Abstract

The invention provides a foam concrete composite board for a fireproof isolation belt. The foam concrete composite board is composed of two foam concrete panels and a polyurethane foam sandwich, wherein sections of the two foam concrete panels are L-shaped; the two L-shaped foam concrete panels can be closed to form a mold cavity provided with a closed end, and polyurethane foam can be poured into the mold cavity to form the foam concrete composite board for the fireproof isolation belt; and the foam concrete panels are made of one of a pulverized fuel ash foam concrete sheet material, a slag foam concrete sheet material, a polystyrene granule light-weight foam concrete sheet material, an expanded perlite foam concrete sheet material and s fiber-reinforced foam concrete sheet material. The composite insulation board has the advantages of excellent fireproof performance, light weight, thermal insulation, low cost and good durability, can be produced into composite boards of different volume weights, and is applicable to the fireproof isolation belt for an external wall of a building.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a foam concrete composite board for a fireproof isolation belt. Background technique [0002] The existing building insulation boards are mainly organic polystyrene boards, which have poor fire resistance and potential safety hazards. In the actual construction process, it is necessary to set up a fire barrier. The traditional fire barrier materials are mainly rock wool, inorganic thermal insulation mortar, polyphenolic foam, etc. These materials have disadvantages such as high price, complicated construction technology or insufficient durability. [0003] Utility model patent 200820104071.6 relates to a polyurethane rigid foam sandwich integrated thermal insulation lightweight wallboard. A layer of polyurethane rigid foam sandwich layer is poured between two layers of concrete lightweight wallboards to make an integrated thermal insulation wallboard. When the patented product ...
