Waterproof and wear-resistant composite flooring and production method

Abstract

A waterproof and wear-resistant composite flooring and production method is disclosed and comprises the following steps: a PVC composite layer prefabricated part (3) is made, and corona treatment andpunching treatment are performed on the cushion layer (2); finally, the PVC composite layer prefabricated part (3), the cushion layer (2) and the waterproof base material layer (1) are composited intoone at a time. The method is simple in technology, easy in implementation, short in production cycle, and low in production cost. Manpower and material resources needed in production processes can bereduced, obtained waterproof and wear-resistant composite flooring is simple in structure and high in water resistance and wear resistance and can be prevented from being easily swollen or layered ordeformed.

Description

technical field [0001] The invention relates to the technical field of composite floors, in particular to a waterproof and wear-resistant composite floor and a production method thereof. Background technique [0002] Composite flooring is composed of multiple layers of different materials that are pasted together with glue in sequence. The material layer of composite flooring includes a wear-resistant layer on the surface, a plastic layer in the middle, and a substrate layer on the bottom layer as the main layer. The substrate layer is selected Wood-plastic layer or stone-plastic layer, the current processing technology of composite flooring is simply glue coating, hot pressing and pressure holding, specifically pressing the corresponding material layer upwards on the surface of the base material layer, which is first Glue is rolled on the adjacent surfaces of two adjacent material layers, and then heat-pressed and pressure-holding is carried out to finally obtain a composit...

AI Technical Summary

Problems solved by technology

[0004] First, the traditional production process has many steps, requiring multiple hot pressing and long-time pressure-holding processing, and the pressure-holding process after each hot-pressing needs to hold pressure for 12 to 24 hours. The traditional production process requires High energy consumption, long production cycle, low effective efficiency and high production cost

[0005] Second, during the hot pressing process, the middle plastic layer cannot discharge the air existing in the middle area. After the pressing operation is completed, there are often various bulges in the hollow area, which seriously affects the quality and life of the composite floor

[0006] Third, due to the different material characteristics between different materials, their coefficients of thermal expansion and contraction are also different. Different material layers have different degrees of internal stress in the production process, and glue is used as a binder. Delamination is still easy to occur between layers. After the composite floor is put into use for a period of time, it is easy to warp around the composite floor, and its waterproof performance is also very poor.
