Abstract

The invention discloses a composite fire-proof insulation board and a preparation method thereof. The composite fire-proof insulation board is prepared from the raw materials of 30-80kg of cement, 20-60kg of coal ash, 0.2-0.7m<3> of glazed hollow beads, 0.2-0.7m<3> of expandable polystyrene (EPS) particles, 0.2-1kg of methylcellulose and water, wherein, the weight of the water accounts for 50% of the weight of the raw materials. The composite fire-proof insulation board provided by the invention is characterized by short curing time and high early strength.

Description

technical field [0001] The invention specifically relates to a composite material fireproof insulation board and a preparation method thereof. Background technique [0002] Existing fireproof insulation boards are directly paved and formed after mixing and stirring raw materials. Usually, excessive water is required to prepare dilute slurry for wet forming. At the same time, the curing time is long, which is not conducive to mass production. Contents of the invention [0003] The purpose of the present invention is to solve the defects in the prior art, and provide a composite material fireproof insulation board with short curing time and a preparation method thereof. [0004] In order to achieve the above purpose, the present invention provides a composite material fire-proof insulation board, which is composed of the following raw materials: 30-80kg of cement, 20-60kg of fly ash, 0.2-0.7m vitrified beads 3 , EPS (expandable polystyrene) particles 0.2~0.7 m 3 , ...
