Abstract

The invention relates to a flame-retardant pearl wool foam board which consists of a main body, a flame-retardant layer and an auxiliary layer, wherein the flame-retardant layer consists of polyacrylate, aluminum sulfate octadecahydrate, basic magnesium aluminum carbonate, polycarbonate and a dispersant; and the auxiliary layer consists of waterborne polyurethane, polyacrylamide, carboxymethyl guar gum, carboxymethyl cellulose, an activated carbon fiber, porous latex and a dispersant. The flame-retardant pearl wool foam board provided by the invention has a flame-retardant layer, both the aluminum sulfate octadecahydrate and the basic magnesium aluminum carbonate can emit moisture when being combusted, then an ambient temperature can be reduced, and functions of fire extinguishing and flame retardancy can be achieved. Meanwhile, due to adoption of the auxiliary layer consisting of dilution materials, moisture in the environment can be absorbed by the auxiliary layer at normal time, andthe absorbed moisture can be released in combustion or at a high temperature; and partial humidity of the environment can be increased, partial temperatures of the environment can be reduced, then combustion can be prevented or retarded, the flame-retardant layer is assisted, and the flame retardancy effect of the pearl wool foam board can be improved.

Description

technical field [0001] The invention relates to the field of pearl cotton, in particular to a flame-retardant pearl cotton foam board. Background technique [0002] EPE pearl cotton, also known as polyethylene foamed cotton, is a new type of environmentally friendly packaging material. It is composed of numerous independent bubbles produced by physical foaming of low-density polyethylene fat, and has a non-crosslinked closed-cell structure. Pearl cotton has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance. It is an ideal substitute for traditional packaging materials. However, the flame retardancy of pearl cotton is relatively general, which prevents its application range. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art and provides a foamed pearl cotton board with go...
