Fiber-reinforced polyvinyl chloride composite floor and its production process

Abstract

The invention discloses a fiber reinforced polyvinyl chloride composite floor and a production process thereof, belonging to the technical field of new materials. Through the use of carbon fiber, basalt fiber and glass fiber as additives, the three-layer fiber reinforced polyvinyl chloride composite floor is formed by using co-extrusion process. The upper and lower surface layers are made of fiber reinforced polyvinyl chloride, and the middle layer is polyvinyl chloride flooring. Using of fiber thermal stability and scientific formula, fiber reinforced polyvinyl chloride composite floor is lighter than the stone floor, and compared with ordinary PVC plastic flooring, the fiber reinforced polyvinyl chloride composite floor does not deform after sunlight irradiation for a long time and stability is good at average temperature. Fiber reinforced polyvinyl chloride composite floor is the ideal substitute for wood and machinable wood skin compound high-grade new floor is the most popular product in international market. The application technical problem of plastic flooring is solved by fiber modification, so that the technology application performance and the product technology content are improved and additional value is added.

Description

technical field [0001] The invention belongs to the technical field of new materials, and relates to a fiber-reinforced polyvinyl chloride composite floor and a production process thereof. The fiber-reinforced polyvinyl chloride composite floor is produced by using carbon fiber, basalt fiber and glass fiber as additives and adopting a foaming co-extrusion production process. Background technique [0002] Along with the increasing shortage of domestic and foreign timber markets, various new types of floors that replace timber emerge in an endless stream. At present, various floorings with PVC as the main raw material have become mainstream products in the domestic and foreign markets. However, ordinary PVC plastic floors have serious deformation problems, especially long-term sunlight or geothermal temperature, which will cause deformation of plastic floors. .

AI Technical Summary

Problems solved by technology

At present, various floorings with PVC as the main raw material have become mainstream products in the domestic and foreign markets. However, ordinary PVC plastic floors have serious deformation problems, especially long-term sunlight or geothermal temperature, which will cause deformation of plastic floors.

The deformation of the wood-plastic floor is slightly better, but there are still deformation problems

The deformation of the stone-plastic floor is relatively small, but the weight of the floor per unit area increases

Due to the deformation of ordinary PVC plastic flooring, PVC boards cannot be processed into high-grade laminated veneer flooring. However, veneer flooring is very popular in the international market, and the profit margin is relatively high.
