Problems solved by technology

But there are also some problems. For example, almost all PVC floors use PVC wear-resistant layer, and UV coating treatment is done on the wear-resistant layer to adjust the brightness and protect the effect, but this is inevitable in the long-term use process. It will be affected by environmental changes, especially the generation of harmful substances such as VOC under high temperature conditions, which will affect people's health
And even if the PVC wear-resistant layer is treated with UV coating, its scratch-resistant effect is very poor, and scratches are easily generated
Although the same laminated floor is cheaper and wear-resistant than solid wood flooring, it is not environmentally friendly. The reinforced composite uses MDF as the substrate. MDF is made of wood powder and glue, which is airtight, has poor foot feel, is not water-resistant, and is not moisture-proof. , and high formaldehyde emission
The surface of the stone-plastic base material is pressed with the conventional melamine wear-resistant layer. Due to the different tension of the material, the plate shape is prone to warping and deformation when heated or used for a long time.
The entire floor material will have bad phenomena such as "arching", which cannot be used normally
The combination of melamine wear-resistant paper and inorganic board, due to the strong rigidity of the inorganic board, is not easy to deform when exposed to temperature, and can well solve the problem of board warping, but the material is not easy to process and recycle, the production process is relatively complicated, and the defect rate is high. Conducive to production, and the overall cost is higher

Description

technical field [0001] The invention belongs to the technical field of floor manufacturing, and relates to a composite floor, in particular to a scratch-resistant and wear-resistant stone-plastic composite floor. Background technique [0002] PVC flooring is now mature. PVC flooring is a new type of light-weight floor decoration material that is very popular in the world today, also known as "light-weight floor material". It is popular abroad and has entered the Chinese market since the early 1980s. It has been widely recognized in large and medium-sized cities in China and is widely used, such as homes, hospitals, schools, office buildings, factories, public places, supermarkets, businesses, etc. place. But there are also some problems. For example, almost all PVC floors use PVC wear-resistant layer, and UV coating treatment is done on the wear-resistant layer to adjust the brightness and protect the effect, but this is inevitable in the long-term use process. It will be ...
