Abstract

The invention discloses an aerated concrete block with high thermal insulation property. The aerated concrete block with high thermal insulation property is prepared by the following raw materials by weight: 0.04-0.06 part of nekal BX, 0.003-0.01 part of magnesium powder, 0.04-0.05 part of triethanolamine oleate, 4-5 parts of cement, 0.1-0.3 part of oxidized starch, 0.002-0.006 part of glycerin triacetate, 0.01-0.03 part of ethylene glycol monomethyl ether, 0.1-0.5 part of wood fiber, 10-20 parts of expanded perlite powder, 7-9 parts of slag powder, 17-19 parts of kaolin, 1-2 parts of alum and 0.2-0.4 part of chitosan.

Description

technical field [0001] The invention relates to the field of aerated bricks, in particular to an aerated concrete block with high thermal insulation performance. Background technique [0002] Aerated bricks are aerated concrete blocks produced by high-temperature autoclaved equipment. "Aerated brick" can be understood as a simplified or a general name. The range of products it covers should be larger, that is, bricks produced by various other processes including autoclaving. [0003] In the past, the wall materials used in the construction market were mainly red bricks, but now many advanced areas have completely banned the use of red bricks. [0004] The existing technology of aerated bricks is slow to develop and cannot meet the diversified market demands. Contents of the invention [0005] The object of the present invention is to provide an aerated concrete block with high thermal insulation performance. [0006] The above purpose is achieved through the follow...
