Inorganic closed-cell foamed insulation board

Abstract

The invention provides an inorganic closed-cell foamed insulation board, which comprises the following component in part by weight: 10 to 15 parts of Portland cement, 6 to 10 parts of magnesium oxychloride cement, 3 to 5 parts of Ca powder, 5 to 7 parts of Si powder, 2 to 15 parts of quartz sand, 50 to 60 parts of flyash, 10 to 15 parts of plant fiber and 2 to 3 parts of glass fiber. The insulation board is prepared by foaming the raw materials by adding a foaming agent. The insulation board has good flame retardancy and can reach the A-level standard, and has high strength, the unit weight of less than 400 and the water absorption lower than the national standard.

Description

technical field [0001] The invention belongs to the technical field of heat insulation boards, and in particular relates to an inorganic closed-cell foam insulation board. Background technique [0002] At present, more and more attention has been paid to the fire prevention of building insulation materials, and the existing organic insulation materials cannot meet the fire prevention requirements. Contents of the invention [0003] Aiming at the above-mentioned deficiencies of the existing building thermal insulation materials, the present invention provides an inorganic closed-cell foam thermal insulation board, whose raw material components and parts by weight are configured as follows: ordinary cement: 10-15 parts; magnesium oxychloride cement: 6-10 parts parts; Ca powder: 3-5 parts; Si powder: 5-7 parts; quartz sand: 2-3 parts; fly ash: 50-60 parts; plant fiber: 10-15 parts; glass fiber: 2-3 parts ; The insulation board is obtained by foaming the raw material with a f...
