Manufacturing method of environment-friendly nontoxic decorating plate

Abstract

The invention discloses a manufacturing method of an environment-friendly nontoxic decorating plate, and belongs to the technical field of building materials. The method comprises the steps that a hindered amine light stabilizer is dispersed in melamine modified resin, and woodgrained paper is sequentially subjected to first-time immersion treatment, first-time drying, second-time immersion treatment and second-time drying in the melamine modified resin to prepare a high-color-fastness facing layer; the melamine modified resin is prepared, particularly, thee times of melamine addition polycondensation are carried out, one time of urea polycondensation is carried out, and the mole ratio of HCHO to NH2 is 0.5; second-time immersion treatment is carried out, particularly, nanosilicon dioxideis added successively, wherein the adding amount of the nanosilicon dioxide is 8% of the mass of the melamine modified resin; the upper surface and the lower surface of a substrate layer are coated with environment-friendly glue, wherein the substrate layer is multiply plywood; the upper surface and the lower surface of a substrate are prepressed, wherein prepressing unit pressure is 0.8 MPa, andtime is 30 min; a prepressing plate is subjected to hot pressing, wherein hot pressing unit pressure is 1.2 MPa, time is 15 min, the temperature is not lower than 120 DEG C, and finally the decoratingplate with high environmental protection performance is obtained.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a method for manufacturing a decorative board, in particular to a method for manufacturing an environmentally friendly and non-toxic decorative board. Background technique [0002] Decorative board is a kind of man-made board. It is a thermosetting laminated plastic made of high-temperature and high-pressure adhesive after chemical treatment with a variety of special papers. The board surface has various wood grains or patterns, bright and flat, bright and beautiful. The walls and roofs of many high-end houses, well-made cabinets, cabinets, tables, beds, workbenches for precision instruments, laboratory test benches, TV sets, radios and other shells of broadcasting and telecommunications equipment, mostly use this new type of material. Decorative plates. [0003] After the existing plywood, blockboard and veneer are decorated, indoor odors such as toluene and xylene can...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the existing plywood, blockboard and veneered panels, after being decorated, indoor toluene, xylene and other odors cannot dissipate for a long time, which seriously affects the living room environment and restricts the use of products. There are few volatile organic substances in the room, but the formaldehyde emission of impregnated paper-decorated wood-based panels is significantly higher than that of ordinary wood-based panels. An environmentally friendly and non-toxic decorative panel manufacturing method is proposed, which can improve the environmental performance of decorative panels
