B02 grade light autoclaved sand aerated concrete fireproof insulation board and preparation method thereof

Abstract

Disclosed is a fire-proof thermal-insulation board of aerated concrete of B02-level lightweight autoclaved sand and its preparation method. Components of the thermal-insulation board are quartz sand, lime, cement, gypsum, aluminum powder, and foam stabilizer, weight percentages of the components are: 56%˜60% of the quartz sand, 8%˜11% of the lime, 20%˜30% of the cement, 2%˜4% of the gypsum, 0.24%˜0.26% of the aluminum powder, and 0.02%˜0.03% of the foam stabilizer. The fire-proof thermal-insulation board is made of an inorganic non-metallic material with lightweight, non-inflammable property and good thermal-insulation performance. The present disclosure well solves the thermal bridge problem of external wall of the building, and has A1-level fire-proof performance and good durability with the same service life as the building. The present disclosure overcomes low product strength, and inconvenience in transportation and construction in the prior art, reduces types of admixture used in the manufacturing process, and reduces the manufacturing cost.

Description

technical field [0001] The invention relates to a new type of green and environment-friendly building material, in particular to a B02 grade light autoclaved sand aerated concrete fireproof and heat preservation board and a preparation method thereof. Background technique [0002] At present, the insulation materials in the domestic construction market mainly include traditional polymer flammable insulation materials such as EPS boards and XPS boards. Their use has huge safety hazards, such as low fire protection rating, short life, poor wind pressure resistance, and wall cracks. , hollowing, shedding and other defects. In recent years, there have been many large fires caused by the low fire protection level of insulation materials. Therefore, it does not meet the requirements of modern people who advocate safety, green, environmental protection, non-toxic, and low VOC. [0003] B02 light autoclaved sand aerated concrete fire insulation board has the characteristics of fire...

AI Technical Summary

Problems solved by technology

[0005] First, the B02 light autoclaved sand aerated concrete fireproof insulation board has high requirements on raw materials, and the product mix ratio is complex

[0006] Second, the production stability of B02 light autoclaved sand aerated concrete fireproof insulation board is poor, and the control requirements of each process link in the production process are relatively high

[0007] The third is that B02 grade light autoclaved sand aerated concrete fireproof insulation board is a brittle inorganic non-metallic material with relatively low strength and has high requirements for production, transportation and construction.
