Abstract

The invention discloses a composite material for construction and a preparation method thereof. The composite material is prepared from, by weight, 10-15 parts of fly ash, 1-4 parts of calcium hydroxide, 5-16 parts of hemp fiber, 24-37 parts of form-stable phase change material, 5-12 parts of short carbon fiber, 4-8 parts of modified starch, 13-19 parts of modified cellulose aerogel, 1-3 parts ofmodified layered dihydroxy compound hydrotalcite and 21-38 parts of polyving akohol. The composite material has the excellent functions of heat preservation, fire proofing, sound insulation, moistureproofing, mildew proofing and shock absorption, the composite material is green and environmental-friendly, light in weight, good in mechanical performance and good in durability, and the problems ofexcessively heavy volume weight, poor heat preservation effect, toxicity and harm, easily becoming mildewed and incapable of insulating sound are solved.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a composite material for construction and a preparation process thereof. Background technique [0002] With the rapid development of economy and society, people's requirements for living comfort are increasing, and the requirements for environmental protection, heat preservation and moisture resistance of building materials are also getting higher and higher. Existing thermal insulation materials have technical defects such as poor ratio of thermal insulation particles and adhesives, brittleness, high water absorption, excessive product bulk density, and easy cracking. These technical defects are closely related to frequent accidents of thermal insulation materials falling. The direct fall or collision of building insulation materials will cause great harm to pedestrians, vehicles, etc., and seriously threaten the lives and property safety of the people. In addition, summer an...
