Problems solved by technology

PVC stone-plastic floor is a new type of floor decoration material developed by high-quality, high-tech research and development. It uses natural marble powder to form a solid base layer with high-density, high-fiber mesh structure, and the surface is covered with super wear-resistant polymer PVC. The wear-resistant layer is processed through hundreds of processes, and the PVC stone-plastic floor is easily deformed due to insufficient strength during the processing process, which seriously affects the quality of the PVC stone-plastic floor. The requirements for the mechanical properties of the PVC stone-plastic floor are not only not met. , its weather resistance and waterproof performance are important factors affecting its se

Abstract

The invention discloses a PVC stone plastic floor and a preparation method thereof, which belong to the field of stone plastic floor manufacture. The stone plastic floor comprises the following raw materials in parts by weight: 200-300 parts of PVC resin powder, 400-800 parts of calcium filler, 20-40 parts of glass fiber, 1-2 parts of an activator, 3-7 parts of a thickener, 5-10 parts of a dispersant, 10-15 parts of a stabilizer, 5-15 parts of a plasticizing regulator, and 5-10 parts of a defoaming agent. The method not only significantly improves the mechanical properties of the PVC stone-plastic floor, but also improves the weather resistance of the PVC stone-plastic floor, enhances the chemical corrosion resistance of the PVC stone-plastic floor surface, and avoids the deformation of the PVC stone-plastic floor during the processing by the specific ratio of the raw material components, the prepared PVC stone plastic floor has excellent waterproof performance and sound insulation effect, and has higher toughness, high strength and lower weight than that of the traditional stone plastic floor, and has short production cycle and low cost, and is suitable for production of the PVC stone plastic floor.
