Abstract

The invention relates to a dual organic modified cement-base expanded perlite fireproof thermal-insulation board and a preparation method thereof. The dual organic modified cement-base expanded perlite fireproof thermal-insulation board mainly comprises the following components in percentage by weight: 50-80% of organic modified expanded perlite, 20-35% of Portland cement, 5-10% of polymer emulsion, 0-3% of active filler and 0.5-1% of additive. The preparation method comprises the following steps: evenly mixing raw materials, adding water, stirring to obtain a semidry material, filling the semidry material into a mold, compacting into a fireproof thermal-insulation board, and finally, carrying out high temperature steam curing for several hours. The dual organic modified cement-base expanded perlite fireproof thermal-insulation board not only has the advantages of strong deformation resistance, favorable crack resistance, shock resistance, favorable weather resistance, long service life, favorable fire resistance (Grade A) and the like in the Portland cement-base expanded perlite inorganic thermal-insulation board, but also has the advantages of high strength, low density and low elastic modulus. The invention has the characteristic of high production efficiency, and can implement large-scale production.

Description

technical field [0001] The invention belongs to the field of expanded perlite fireproof insulation board and its preparation, in particular to a double organic modified cement-based expanded perlite fireproof insulation board and its preparation method. Background technique [0002] In recent years, fires of building external insulation materials have occurred one after another in China, causing serious casualties and property losses. Flammable and combustible building external insulation materials have become a new kind of fire hazard, and the fires caused by them have shown a trend of frequent occurrence. Therefore, the fire safety of external wall insulation materials has become the focus of the fire departments. Among the large-scale application of building energy-saving thermal insulation materials, polystyrene foam board has become the most mainstream external thermal insulation material because of its light weight, good thermal insulation and thermal insulation.
