The application prospect of calcium carbonate in stone-plastic floor is broad
PVC floor is a new generation of floor decoration material which is popular in the European and American home decoration market. It was first born in Europe in the early 1960s and was introduced into production and use by the United States in the 1960s. After decades of research and improvement in Europe and the United States, PVC floor materials have been widely promoted and used in the world. The application of PVC floor materials in families in Europe, the United States, Japan and South Korea has occupied more than 40% of the market share, and shows a gradual upward trend.
SPC is the abbreviation of stone plastic composite, literally translated into 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 to enhance product stability. It can also be called SPC flooring, but its stone powder content is much lower than SPC products. There is also a wood plastic composite floor, which is abbreviated as WPC by mixing wood flour and PVC. The products introduced in this paper are lock SPC products with high content of stone powder.
Advantages of SPC Floor
The advantages of the SPC floor
Green environmental protection zero formaldehyde
Healthy, green and environmentally friendly building materials are people's diligent goal. The main source of formaldehyde in flooring is glue. Most flooring installation needs glue. Composite flooring is made of glue, so the problem of formaldehyde in decoration has been unavoidable. The reason why SPC floor can achieve 0 methanol comes from its unique material and composition.
SPC floor is made of PVC base material extruded by extruder combined with T-shaped die. PVC wear-resistant layer, printing layer and PVC base material are respectively heated and laminated by calender. The process is simple and the lamination is completed by heat without glue. The main material of SPC stone-plastic floor is natural stone powder. The material does not contain formaldehyde and any radioactive elements. It can provide a comfortable and healthy environment for residents.
Waterproof, skid-proof, fire-proof and flame-retardant
SPC floor has strong waterproof performance. It solves the problem of mildew, arch and peculiar smell of traditional wood flooring due to high humidity. Compared with the PVC floor made of LVT sheet, the stone powder content of lock-type SPC floor is higher. Paving without glue can effectively avoid the glue deformation caused by soaking.
When SPC floor is immersed in tap water at room temperature for 24 hours, there is no bubble deformation on its surface, and its expansion rate is only 0.12%. Compared with other floor products, this expansion rate can be neglected, which shows that the waterproof performance of SPC floor is extremely superior.
The fire-proof index of SPC floor can reach B1 level, next only to stone, and SPC floor itself will not burn, high temperature is not easy to deform, can effectively play a flame-retardant role.

Strengthened wood flooring is a relatively wear-resistant material in the flooring industry. The wear resistance of its aluminium trioxide surface can reach more than 12,000 revolutions. The wear resistance of SPC floor surface varies according to the thickness of its PVC wear-resistant layer. The wear resistance of 0.55mm PVC wear-resistant layer can reach around 12000-20000 rpm. Compared with the soft LVT PVC floor, its wear resistance and impact resistance are stronger.
Because of the superior wear resistance of SPC floors, SPC floors are becoming more and more popular in hospitals, schools, office buildings, shopping malls, supermarkets, transportation and other places with large traffic.
Elastic Restoration Noise Reduction Antibacterial
SPC floor feet feel comfortable, and has good resilience recovery and impact resistance, not easy because of external impact and damage, depression and other issues. SPC products with cork mat or EVA foam on the bottom can effectively absorb the impact force, thus reducing the reaction force of the ground to the human body when falling down.
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 antimicrobial effect, so that children and the elderly can better contact with the floor, comfortable and healthy.
Low expansion coefficient without expansion joint
Low expansion coefficient is the biggest advantage of locking SPC floor compared with traditional floor materials, which can effectively avoid thermal expansion and contraction caused by external environment, and avoid floor deformation.
Due to its low expansion coefficient, large area pavement can be realized without reserving expansion joints in the process of SPC floor paving. Traditional floor paving over 8 meters requires the installation of T-shaped strips, while stone-plastic floor can be paved in a large area of 400 square meters without T-shaped strips, and no buckles need to be installed in the doorway position when the whole house is paved.
SPC Floor Heating Test
In order to understand the tolerance of SPC floor more clearly, we quoted a small experiment. The SPC floor with high stone powder content and the traditional LVT floor with low stone powder content were put into a closed space at the same time, and then the indoor temperature was gradually raised and lowered to observe the surface changes of SPC floor and LVT floor.
