Composite board of artificial base material and adhesive impregnated veneer and production process

Abstract

The invention discloses a composite board of an artificial base material and an adhesive impregnated veneer and a production process. The composite board comprises the artificial base material, and the melamine adhesive impregnated veneer is arranged on the front surface of the artificial base material. The production process comprises the following steps of A, carrying out dull polish treatment on the surface of the artificial base material to obtain a board A; B, coating the front face and the back face of the board A with a waterproof high-temperature-resistant bonding adhesive to obtain aboard B, wherein the coating amount of the waterproof high-temperature-resistant bonding adhesive is 30-100 g / m<2>; C, paving the melamine adhesive impregnated veneer on the front face of the board B,and paving melamine impregnated paper on the back face of the board B to obtain a board C; D, performing hot press molding on the board C to obtain a board D, wherein the hot pressing temperature is115-180 DEG C, the pressure is 0.5-1.2 MPa, and the pressure maintaining time is 500-1200 seconds; and E, cooling and shaping the board D, and cutting to obtain a finished product board, wherein the cooling temperature ranges from 20 DEG C to 60 DEG C, the pressure ranges from 0.5 MPa to 1.2 MPa, and the pressure maintaining time ranges from 500 seconds to 1500 seconds. According to the compositeboard of the artificial base material and the adhesive impregnated veneer and the production process, the simple and convenient production, the good wear-resisting property and the high waterproof andflame-retardant properties can be considered at the same time.

Description

technical field [0001] The invention relates to an artificial composite board, in particular to a composite board made of artificial base material and glue-impregnated veneer and its production process. Background technique [0002] Artificial base materials mainly include plywood, Polaroid board, fiberboard, blockboard, particle board, wood wool board and sawdust board. A layer of surface-bonded material that facilitates consumer selection for purchase. For materials such as Polaroid board and vinyl material board (such as stone-plastic board, wood-plastic board, etc.), the surface bonding materials currently include PVC color film + wear-resistant, wood sheet and melamine impregnated paper. However, due to the relatively smooth surface of substrates such as Polaroid boards and vinyl material boards, traditional melamine-impregnated paper cannot be directly pressed and pasted with vinyl materials to form it, requiring multiple processes for secondary molding.

AI Technical Summary

Problems solved by technology

However, due to the relatively smooth surface of substrates such as Polaroid boards and vinyl material boards, traditional melamine-impregnated paper cannot be directly pressed and pasted with vinyl materials to form it, requiring multiple processes for secondary molding. At the same time, melamine-impregnated paper is a printed product with poor texture and visual aesthetics. After curing and forming, melamine-impregnated paper can achieve strong wear resistance, but because it is printed and then impregnated with melamine glue products, so once the wear-resistant layer and printing layer are damaged, the stability and aesthetics of the product will be greatly reduced

As for wood sheet, it has strong texture and good visual aesthetics, but its wear resistance is very poor. To improve its wear resistance, it must go through various painting processes, which are complicated, and its flame retardancy and waterproof performance are extremely poor.

PVC color film + wear-resistant method is a PVC printed product with poor texture and visual aesthetics, and surface anti-wear materials need to be applied in the later stage of the production process, but even so, the wear-resistant ability is still poor

Therefore, the existing technology has the problem of being unable to take into account the simple and convenient production, good wear resistance, strong waterproof and flame retardant properties at the same time.
