Problems solved by technology

However, commonly used materials such as PVC materials and polyurethane have strong polarity, and the produced fireproof boards are relatively hard and brittle, and are easy to break
The commonly used solution is to modify PVC or polyurethane materials to make them have better ductility, but often only 30% to 40% of flame retardants can be added to them, and excessive flame retardants will also cause damage. Reproduces the problem of increased hardness and brittleness of the produced sheet

Abstract

The invention provides a high-toughness high-flame-resistance foaming material. The foaming material comprises the following raw materials in parts by weight: 83-93% of magnesium hydroxide, 9-12% of sawdust powder, 3.5-6% of perlite, 2-4.5% of glass fiber cloth and 0.3-1.5% of a foaming agent. Furthermore, the invention also provides a preparation method of the high-toughness high-flame-resistancefoaming material, and the preparation method comprises the following steps: (1) bulking and crushing various materials; and (2) diluting the foaming agent, then uniformly mixing the diluted foaming agent with other materials, and putting the mixture into a mold for self-foaming. The material prepared by the method is particularly suitable for being used as a fireproof plate core material, and tests prove that the fireproof plate core material achieves A1-grade fireproof performance, is non-toxic, smokeless and odorless, and has high toughness, crack resistance and strength than products in the market.

Description

technical field [0001] The invention relates to the technical field of fire and flame retardant materials, in particular to a high-toughness and high-flame-resistance foaming material and its preparation method and application. Background technique [0002] At present, PVC resin, polyurethane and other materials are widely used in the manufacture of fireproof boards due to their good dissolution polymerization properties and strength, such as floor leather, floor tiles, foam materials, etc. However, commonly used materials such as PVC materials and polyurethanes have strong polarity, and the produced fireproof boards are relatively hard and brittle, and are easy to break. The commonly used solution is to modify PVC or polyurethane materials to make them have better ductility, but often only 30% to 40% of flame retardants can be added to them, and excessive flame retardants will also cause damage. The problem of increased hardness and brittleness of the produced sheet arose ...
