PVC flooring is a new generation of floor decoration materials popular in Europe and the United States home paving market, which was first born in Europe in the early 1960s, and was introduced in the United States in the 1960s. After decades of research and improvement in Europe and the United States, PVC flooring has been widely promoted and used in the world, in Europe and the United States, Japan and South Korea and other regions of the family application has occupied more than 40% of the market share, and showing a gradual upward trend.

SPC is the abbreviation of stone plastic composite, literal translation of stone plastic composite material, referred to as stone plastic floor, belongs to a kind of PVC floor. Traditional sheet and coil LVT PVC flooring also contains stone powder used to enhance product stability, which can also be called SPC flooring, but its stone powder content is much lower than SPC products. There is also a mixture of wood flour and PVC abbreviated as WPC wood plastic composite flooring. The products introduced in this paper are locked SPC products with high content of stone powder.

Healthy, green and environmentally friendly building materials are the goal that people strive for. The source of formaldehyde in the floor is mainly glue, most of the floor installation needs to use glue, and the composite floor is made of glue, so the problem of formaldehyde has been difficult to avoid in the decoration. The reason why SPC floor can achieve 0 methanol comes from its unique material and composition.

SPC floor is made of extruder combined with T-mold extrusion PVC substrate, using calender respectively PVC wear-resistant layer, printing layer and PVC substrate, one-time heating laminating, embossing products, simple process, laminating by heat to complete, do not need glue. The main material of the base of SPC stone plastic floor is natural stone powder, which is tested by the national authority and does not contain formaldehyde and any radioactive elements, which can provide a comfortable and healthy environment for residents. SPC flooring has strong water resistance. Solve the traditional wood floor due to high humidity and mildew, arch, odor. Compared with the PVC floor of LVT sheet, the locking SPC floor has a higher stone powder content, and the pavement does not use glue, which can effectively avoid the opening deformation caused by soaking water.

SPC floor soaked in normal temperature tap water for 24 hours, its surface does not appear bubble deformation, and its expansion rate is only 0.12%, compared with other floor products, this expansion rate is negligible, which shows that SPC floor waterproof performance is extremely superior.

SPC floor fire indicators can reach B1 level, second only to stone, and SPC floor itself will not burn, high temperature is not easy to deform, can effectively play a flame retardant role. Laminate wood floor is the more wear-resistant material in the flooring industry at present, and the wear-resistant degree of its aluminum oxide surface can reach more than 12000 RPM. SPC floor surface according to the thickness of its PVC wear-resistant layer, the degree of wear is not the same, 0.55mm PVC wear-resistant layer can reach 12000-20000 revolution before and after, compared with the soft LVT PVC floor its wear-resistant, impact resistance is stronger.

Because of the superior wear resistance of SPC floor, SPC floor is becoming more and more popular in hospitals, schools, office buildings, shopping malls, supermarkets, transportation and other places with large traffic flow.

Because of the superior wear resistance of SPC floor, SPC floor is becoming more and more popular in hospitals, schools, office buildings, shopping malls, supermarkets, transportation and other places with large traffic flow.

SPC floor feet feel comfortable, and have good elastic recovery and impact resistance, not easy to cause damage, sag and other problems due to external impact. SPC products with cork pads or EVA foam on the bottom can effectively absorb the impact force, thereby reducing the reaction force of the ground against the human body during a fall.

The bottom cushion also has good sound absorption performance, which can effectively reduce the transmission of ground noise. The surface coating of SPC floor can inhibit bacterial reproduction and play an antibacterial effect, so that children and the elderly can better contact with the floor, comfortable and healthy. WPC floor using wood plastic composite material, wood plastic base formula added additional bamboo, wood powder, but due to the addition of bamboo, wood powder, in the processing and recycling processing is more difficult, the current WPC floor substrate formula with little or no wood powder.

WPC flooring combines the water resistance of LVT products with the stability of SPC products, and the overall hardness is improved compared to LVT products, while also being as easy to install as laminate flooring. As shown in the picture, it has added cork and EVA pads, and the foot feel and sound insulation have been greatly improved compared to the LVT floor. The floor uses a stone-plastic composite material, also known as RVP(rigidvinyl plank) in Europe and the United States, a rigid plastic floor. The main raw materials of the floor base are PVC resin and natural stone powder (calcium carbonate).

Compared with LVT floor, WPC wood plastic floor is higher, so SPC stone plastic floor substrate density, higher hardness, floor stability is stronger, more solid and reliable, with better mechanical strength, as well as excellent tensile resistance, extrusion resistance, impact resistance. SPC floor and other PVC floor production process is the same, through high temperature and pressure to make the floor of SPC base, surface wear layer, printing layer one-time fit, avoid the use of glue, from the source to achieve zero formaldehyde. SPC floor does not contain formaldehyde, benzene, VOC and other harmful gases, in line with national environmental standards and European standards, after decoration, non-toxic, tasteless and pollution-free, 24 hours after you can immediately move in, truly achieve today's installation tomorrow, is a real green environmental protection products.

In this warm, humid city in southern China, with plenty of rain, floors can easily become moldy and deformed, breeding bacteria. The unique material composition of the SPC floor makes it not afraid of wind and rain, and can effectively prevent mildew and waterproof, so it is not only the preferred safety floor for the living room and bedroom in home improvement, but also very suitable for the kitchen bathroom. In the northern cities of China, most of the home decoration uses geothermal, SPC floor density is high, physical properties are stable, and thermal conductivity is good, heat dissipation is uniform, the use of home decoration floor heating will not expand deformation. SPC floor in Europe, America, Japan and South Korea and other countries and regions, is the first choice for home heating floor.

It is well known that hospitals pay special attention to the hygiene and quality of decoration and equipment. Providing a sterile, environmentally friendly environment is a must. Many hospitals at home and abroad have paid attention to the selection of interior materials, and the antibacterial property of SPC floor makes it a new upstart of hospital floor material selection. The wear-resistant layer of the specially treated SPC floor has good anti-slip property, and compared with ordinary ground materials, the floor feels more astringent in the case of water, and the application in the hospital can effectively avoid the secondary injury caused by the patient's fall.

Green environmental protection, does not contain formaldehyde, benzene, VOC and other harmful gases, after decoration, non-toxic, tasteless and pollution-free, children in a healthy formaldehyde-free indoor environment to learn more conducive to health.

The wear-resistant layer of the specially treated SPC floor has good anti-slip properties, making it less easy for children to fall.

SPC floor feet feel comfortable, for heavy impact damage has a strong resilience, can greatly reduce the impact on children when falling.

At the same time, SPC floors are easy to clean and stain resistant. Therefore, in public places with high public safety requirements, such as airports, kindergartens, schools, etc., it is an ideal ground decoration material.

SPC floor has a sound-absorbing effect that cannot be compared with ordinary ground materials, which is very suitable for all kinds of commercial places (such as malls, restaurants, theaters, etc.).

The PVC wear-resistant layer on the surface of the SPC floor has good wear resistance, and can be used for 5-10 years under normal circumstances according to the thickness, which is very suitable for public places with many people.

SPC floor fire indicators can reach B1 level, second only to stone. Flame retardant, no spontaneous combustion, automatically extinguished within 5 seconds of leaving the flame, will not produce asphyxiating toxic and harmful gases.

SPC floor has four sides of the lock, glue-free installation is more environmentally friendly, compared with the floor tile, the floor does not need cement, saving labor and time and money. It can be combined with different colors of materials to lay out a variety of material splicing effect, beautiful atmosphere.

As a kind of PVC floor, SPC floor has been widely used in Europe, America, Japan and South Korea and other countries, because of its convenient construction, low price, rich variety, green environmental protection and other characteristics, is gradually replacing wood flooring and marble, become the mainstream interior decoration materials.

At present, the concept of the Chinese people in the field of housing and home improvement is relatively conservative, and the acceptance of new materials and new processes abroad is slow, and many products are popular in foreign countries before they will be accepted and recognized by the Chinese people.

As of the end of 2017, China has more than a dozen enterprises that produce stone plastic flooring, but the domestic market share is less than 3%, and it is mainly used for outdoor engineering projects. Rarely used for home improvement. I believe that when people really understand the advantages of PVC flooring products, they will gradually recognize PVC flooring.
