Abstract

The invention discloses an environmentally-friendly exterior wall heat insulation material and a preparation method thereof, and belongs to the technical field of building materials. The material comprises, by weight, 20-40 parts of meerschaum, 5-15 parts of water glass, 5-15 parts of fly ash, 5-15 parts of volcanic ash, 1-3 parts of a foaming agent, 0.8-1.2 parts of polyvinyl alcohol, 10-30 parts of water, 10-20 parts of a thickener and 2-6 parts of calcined kaolin. The environmentally-friendly exterior wall heat insulation material has the advantages of good heat insulation effect, good heat and sound insulation effects, small water imbibitions, low temperature resistance, and acid and alkali resistance; and the preparation method is simple, and is suitable for large scale production.

Description

technical field [0001] The invention relates to an environment-friendly external wall thermal insulation material and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] With the implementation and development of building energy conservation, thermal insulation materials and products have been paid more and more attention by people. However, the currently used materials are not ideal in various properties, especially in terms of heat preservation, acid and alkali resistance, and weather resistance, which cannot meet people's needs. At present, the most commonly used external wall insulation material is polystyrene plastic foam board, and its main material is polystyrene resin. Because of its high transparency, good rigidity and good chemical corrosion resistance, it has been favored by people. However, it has the defects of large specificity, high thermal conductivity, prone to stress cracking, and high cost. ...
