Preparation and application of composite straw glass fiber inorganic material decorative integrated plate

Abstract

The invention provides preparation and application of a composite straw glass fiber inorganic material decorative integrated plate. The preparation method comprises the steps of mixing raw materials by weight ratio, and pre-compressing the raw materials to obtain a straw fiber inorganic blank material; the raw materials comprise a 40-70 parts of straw fiber, 10-20 parts of glass fiber, 20-50 parts of cement and / or calcium silicate material, 0.5-1 part of cement thermosetting modifier, and 2-5 parts of diisocyanate. A decoration paper dipped by melamine resin is paved on a surface layer of a stainless steel rust template; the pre-compressed straw fiber inorganic blank material is paved in the middle; then they are molded at once to form a composite straw glass fiber inorganic material decorative integrated plate. The molding condition is that the temperature is between 150 and 190 DEG C; the pressure is between 20 and 25 MPa, and the hot pressing time is between 30 and 90s. <{EN2}>The preparation materials are cheap; the method is simple and effective; and the decorative integrated plate with high intensity, flame retardation and waterproof performance is prepared by one time hot pressing molding.

Description

technical field [0001] The invention relates to decorative material technology, in particular to the preparation and application of an inorganic material decorative integrated board. Background technique [0002] Most of the decorative panels currently on the market are laminated with wood fiber and urea triamine adhesive materials. The energy consumption of the raw materials is high, and the manufacturing process has certain pollution, which is not environmentally friendly. At the same time, it cannot guarantee its high flame retardancy and high water resistance. , If you need to increase waterproof, flame retardant and decorative, you need to add various flame retardants, waterproofing agents, and the effect is very small. The surface coating material also requires secondary coating in the process. The products produced by the traditional process have a large amount of chemical residues, such as formaldehyde and other organic additives. The products are not environmentally...

Problems solved by technology

[0003] The purpose of the present invention is to propose a composite straw glass fiber filament for the above-mentioned existing decorative boards that require secondary coating, poor environmental protection, high cost, and difficulty in integrating light weight, high strength, flame retardancy, waterproof, and decoration. The preparation of the inorganic material decorative integrated board, the material alkali cost is low, all of which are waste straws that cause headaches for the environmental protection department, the use of short random glass fiber and low-cost low-alkali ordinary silicate cement
