PVC stone plastic floor and preparation method thereof

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.

Description

technical field [0001] The invention relates to the field of manufacturing stone-plastic flooring, in particular to a PVC stone-plastic flooring and a preparation method thereof. Background technique [0002] With the development of science and technology, plastics are more and more widely used in people's daily life. Plastic products are used in everything from space shuttles to people's tableware, and plastic products are widely used in the building materials industry. The application places of PVC stone-plastic floor include indoor homes, hospitals, schools, office buildings, factories, public places, supermarkets, businesses, stadiums and other places. The floor with PVC plastic as the main material is gradually favored by consumers. 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...

AI Technical Summary

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 service life

The invention patent with the application number CN201710917609.9 discloses a stone-plastic floor and its preparation method. The substrate layer, color film layer and wear-resistant layer are formed by embossing rollers. The stone-plastic floor adopts a one-time molding process to avoid the use of glue, energy saving and environmental protection, and the expansion rate and shrinkage rate are relatively small. The performance is more stable and durable. High temperature, longer service life, but the stone-plastic floor produced by the invention has low mechanical properties and low weather resistance, and the stone-plastic floor is easily deformed during processing, which affects the quality of the stone-plastic floor
