Abstract

The invention discloses a heat insulation building composite material and a preparation method thereof. The heat insulation building composite material is prepared from the following components in parts by weight: 30 to 45 parts of building waste powder, 6 to 8 parts of sodium mercaptobenzothiazole, 5 to 8 parts of methyl acetoacetate, 6 to 10 parts of disodium dihydrogen pyrophosphate, 2 to 6 parts of waterborne polyurethane, 5 to 8 parts of barium metaphosphate, 2 to 5 parts of calendic acid, 7 to 16 parts of illite, 8 to 15 parts of gangue, 5 to 8 parts of fluorocarbon alcohol, 0.5 to 1 part of glycyrrhetinic acid monoglucuronide, 0.5 to 1 part of lignin, and 0.1 to 1 part of water reducing agent. The heat insulation building composite material has the advantages that the heat insulation property is good, the compressive strength and neutral salt mist-resistant property are good, the weight of the heat insulation building material is light, and the requirement of modern buildings is well met; by using the building waste as the raw material, better energy-saving and environment-friendly effects are realized.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a thermal insulation building composite material and a preparation method thereof. Background technique [0002] At present, building energy accounts for a large proportion of the world's total energy consumption, about 27%. The use of external wall insulation materials can save huge energy and reduce CO 2 emissions, from this point of view, external wall insulation materials can be called green energy. Using insulation materials in the construction industry has become one of the best ways to save energy. For today's energy shortage, it is imminent to develop external wall insulation materials with good comprehensive performance. At present, thermal insulation building materials have heavy weight, poor thermal insulation performance, and low compressive strength, which cannot meet the requirements of modern buildings. Therefore, the present invention provides a nove...
