Problems solved by technology

[0003] For building decoration materials, the Chinese national standard (GB8624-2006) has a total of A1, A2, B, C, D, E and F for the combustion performance classification. (GB8624-2006), which belongs to the flame retardant grade, that is, the B1 grade of the standard (GB8624-1997), can only be applied to decorative applications in general places, such as cruise ships and spaceships with high requirements, which are difficult to meet the requirements of use
In addition, there are also non-combustible decorative materials at home and abroad, most of which belong to inorganic boards such as ceramic tiles and gypsum boards. Their shortcomings are insufficient elasticity, poor impact resistance, no nail holding power, etc., and do not have the characteristics of traditional Compute boards.
[0004] On the premise of not changing the existing high density and other performances of the Compaite board, it is difficult for the Compaq board to reach the non-combustible level, that is, the A1 and A2 levels. The main reason is that the fiber raw material itself is a flammable substance. It is a difficult point in the existing technology to change the performance of Composite and reach the non-combustible level

Abstract

The invention relates to a non-combustible high-density compact plate and a preparation method thereof. The non-combustible compact plate comprises a core plate and decoration paper on two sides of the core plate, and is characterized in that: the core plate comprises the following components in percentage by weight: 30 to 45 percent of fiber, 30 to 40 percent of phenolic resin, 10 to 20 percent of inert filler, 10 to 20 percent of flame retardant, 0.3 to 1 percent of dye and 0.15 to 0.7 percent of coupling agent, wherein the diameter of inert filler solid particles is 0.01 to 0.5mm, and the inert filler is one or a combination of more of calcium carbonate, kaolin and talcpowder. The compact plate has the characteristics of high strength, high adhesion, fire resistance and flame retardance, and has the density of about 1.4g / cm<2>, combustion performance reaches a non-combustible level A1 in the national standard on the premise that the high performance such as high density and the like of the compact plate are not changed, and the requirement of special industry on high fire resistance of building decoration materials is met.

Description

technical field [0001] The invention relates to a decorative building material, in particular to a non-combustible high-density combite board and a preparation method thereof. Background technique [0002] Combeite board (also known as Kangbeite board) is a one-piece decorative material produced by dissolution and irreversible aging hardening under high temperature and high pressure. The board material has high stability, shockproof and drop-proof, cold-resistant and heat-resistant, fire-resistant, moisture-proof and smoke-resistant, and the density is mostly 1.3-1.4g / cm 3 Among them, the application range of anti-fold special board is extremely wide, such as kitchen countertops, wash tops, dining tables, desks, door leaves in home life, and even bathroom and toilet cubicles, sinks, reception counters, lockers, ceilings, office panels in public spaces. Desks and office cubicles, etc., can be made of Compiler board. [0003] For building decoration materials, the Chinese na...
