Problems solved by technology

At present, the existing fire-resistant and flame-retardant decorative materials on the market are usually thermosetting resin-impregnated high-pressure decorative laminates obtained by pressing surface paper, colored paper and kraft paper together. This thermosetting resin-impregnated high-pressure decorative laminate (ie HPL: The composition and structure of Decorative high-pressure laminates sheets based on thermosetting resins) is shown in Figure 1. Since the decorative fireproof board is made of pure paper material, although the color is bright and the pattern is rich, it cannot meet people's requirements for being close to nature and for Multi-functional requirements for interior decoration, such as indoor environment, green home, etc.; on the other hand, wood decoration materials rich in aesthetics and texture, such as natural wood, bamboo or recombined technical wood and other wood materials, are very flammable

Abstract

Disclosed is a making method of truewood hot setting resin soaked high-pressure laminated decorative fireproof board, comprising the following steps: immerses a plurality of kraft paper pieces in resin and then dry the kraft paper pieces so as to obtain soaked kraft paper pieces whose resin percentage in weight is more than or equal to 25 percent and less than or equal to 80 percent and whose fugitive constituent percentage in weight is more than or equal to 0.05 percent and less than or equal to 25 percent; pile up the dried kraft paper pieces and cover a truewood skin on the kraft paper pieces to form an initial blank; press the initial blank. In this way, a native truewood decorative fireproof board can be made. The invention is made with natural truewood skin and a plurality of kraft paper pieces immersed in resin under hot press treatment and is pressed into fireproof, heat-resistant, wear-resistant and scrape-resistant decorative materials with both the function of a wooden decorative board and the function of fire resistance of a fireproof board; with the advantages that the invention is of no need to paint, easy to maintain and is environment-friendly, the invention is suitable to be used in the fitment of an office, furniture and cooker.

Description

technical field [0001] The invention relates to a method for manufacturing a decorative fireproof board. Background technique [0002] In recent years, with the rapid development of domestic and foreign construction markets, building decoration materials are also developing and changing with each passing day. While people choose beautiful decoration materials, they also pay more and more attention to the functions of decoration materials, such as waterproof and heat insulation materials. performance, especially the fireproof and flame retardant performance of the material. At present, the existing fire-proof and flame-retardant decorative materials on the market are usually thermosetting resin-impregnated high-pressure decorative laminates obtained by pressing surface paper, colored paper and kraft paper together. This thermosetting resin-impregnated high-pressure decorative laminate (ie HPL: The composition and structure of Decorative high-pressure laminates sheets based o...
