Fire-resistant decorative material and preparation method thereof

Abstract

The invention relates to the technical field of building decoration materials, and aims to provide a preparation method of a fire-resistant decorative material. The process is optimized, the operation is simple, and the fire-resistant decorative material prepared by the method has the characteristics of low formaldehyde content, moisture resistance, water resistance, environment-friendliness and high stability of product quality. The method comprises the following steps of: (1) mixing and stirring 40%-70% by weight of high molecular weight epoxy water-based emulsion, 25%-40% by weight of medium-high molecular weight epoxy water-based emulsion, 1%-5% by weight of a latent epoxy curing agent and an accelerant, 5%-15% by weight of a melamine formaldehyde resin solution and 0.5%-1% by weight of a silane coupling agent to obtain a water-based environment-friendly binder; (2) coating the surface of an inorganic non-combustible core material with the obtained water-based environment-friendly binder in a roller coating mode, then covering the surface, coated with the water-based environment-friendly binder in a roller coating mode, of the inorganic non-combustible core material with a glass fiber surface mat, and standing for 24-48 hours; and (3) sequentially laying decorative paper and wear-resistant paper on the outer surface of the glass fiber surface felt, and carrying out high-temperature and high-pressure hot-pressing curing and compounding to obtain the fire-resistant decorative material.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a refractory decoration material and a preparation method thereof. Background technique [0002] Refractory decorative materials are indispensable materials in many architectural decorations, especially in places with high requirements for fire protection and environmental protection. The refractory decorative material provides the decorative effect of pattern patterns, and when the decorative material is used in public places, it also provides particularly good fire resistance. [0003] At present, the production of such materials in the high-pressure refractory decorative panel industry in the market is mainly through the use of the following raw materials and steps: [0004] The first step: roller coating or spraying the adhesive on the surface of the inorganic non-combustible board (such as high-density cement fiber board), and then heating in an oven t...

Problems solved by technology

[0005] This kind of process has a disadvantage, that is, the production of semi-finished products requires two times of drying and heating. The second is the two-time drying process. The loss of energy and labor will also affect the overall cost of the product. The third is that after kraft paper or other paper is impregnated with phenolic or other glue after high temperature and high pressure curing and bonding, it will be heated indoors in the northern winter. Shrinkage stress will be generated under low humidity conditions, which will have destructive force on the inorganic non-combustible board and cause damage to the board. Fourth, the production of the product requires the coordination of two drying processes, which may also have a potential impact on the delivery of the order
