Thermal insulation material using aerated concrete block crushing particles as raw material, and preparation method thereof

Abstract

The invention relates to a thermal insulation material using aerated concrete block crushing particles as a raw material, wherein the thermal insulation material comprises aerated concrete block waste, cement, sand and a proper amount of water, and a ratio of the aerated concrete block waste to the cement to the sand is 3:1.1:1.2. The preparation method comprises: crushing aerated concrete block waste to achieve the particle size of 20-50 mm, mixing the crushed waste, cement and sand according to the ratio of the aerated concrete block waste to the cement to the sand of 3:1:1, adding a proper amount of water, uniformly stirring in a stirrer, conveying the obtained mixed material to the processing surface, placing and paving the mixed material to achieve the set thickness, coating a cement mortar layer on the upper surface of the paved mixed material having the set thickness, and placing the thermal insulation semi-finished product for more than or equal to 24 h so as to obtain the thermal insulation material with characteristics of good quality and low price and used for partition and wall building, wherein the ratio of the cement to the mortar in the cement mortar is 1:2. According to the present invention, advantages of local material obtaining, low price, good quality and multi-purpose achieving through the one technology are provided.

Description

technical field [0001] The invention relates to the technical field of heat preservation material preparation, in particular to a heat preservation material using broken particles of aerated concrete blocks as raw materials. Background technique [0002] An existing Chinese invention patent with the application number CN201010106091.9 titled "Lightweight Dry Powder Masonry Mortar" discloses a light dry powder masonry mortar comprising cement, fly ash, aerated concrete particles, vitrified micro Beads, PP fiber, latex powder, composite air-entraining agent, the weight ratio of each component is as follows, cement (200-300): fly ash (80-120): air-entrained concrete particles (400-1400): vitrified micro Beads (80-140): PP fiber (0.8-1.6): latex powder (2-12): composite air-entraining agent (3-15). The mortar avoids on-site batching and mixing, reduces construction dust and noise pollution, reduces site occupancy, and has accurate proportioning, low cement consumption, and low ...
