Fire-proof aluminum composite board

Abstract

The invention relates to a fire-proof aluminum composite board which is manufactured by a conventional process from calcium carbonate, lightweight aggregate, needle-shaped powder, kaolin, fluororesin short fiber, quartz sand, a binder and the like. The aluminum composite board manufactured by the ingredients above has obviously improved toughness and workability of core materials and the fire-proof performance can be up to the standard of A2 level.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a fireproof building material, in particular to an A2 grade fireproof aluminum composite board. Background technique [0002] Aluminum-plastic composite board refers to a three-layer composite board with plastic as the core layer and aluminum on both sides, and the decorative and protective coating or film on the surface of the product is used as the decorative surface of the product. It is obtained in the current building decoration materials. widely used. However, the core material of the aluminum-plastic composite panel usually uses polyethylene plastic as the main material, which is easy to decompose at high temperature to produce strong toxic and corrosive substances, and its fire resistance is poor. Meet fire safety requirements. Although some research institutions now improve its fire performance by adding various flame retardant components to poly...

AI Technical Summary

Problems solved by technology

The short fiber can be inorganic, but the poor flexibility of the inorganic fiber causes the brittleness of the core material to be large, and the workability also decreases thereupon; organic fiber can also be used, such as polypropylene staple fiber used in CN101967045A, the short fiber of this short fiber The flexibility is good, but the fire performance of the aluminum composite panel is reduced
