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.

Abstract

A method for producing a waterproof and wear-resistant composite floor. First, a PVC composite layer prefabricated part (3) is manufactured, and then a cushion layer (2) is subjected to corona treatment and punching treatment, and finally the PVC composite layer prefabricated part (3), The upholstery layer (2) and the waterproof base layer (1) are combined into one body at one time, the process is simple, easy to implement, the production cycle is shortened, the manpower and material resources required for the production process are reduced, and the production cost is reduced, and the waterproof and wear-resistant product obtained The composite floor not only has a simple structure, but also has very good waterproof and wear-resistant properties, and the waterproof and wear-resistant composite floor will not produce bulges, and it is not easy to delaminate or deform.

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...
