Abstract

The invention discloses a high performance reflective insulating gypsum-based composite insulation material and a preparation method thereof, belongs to the technology field of architectural heat preservation material and preparation thereof, and aims to solve the problem of poor durability of building insulation materials in existing technology. According to the technical solution, the insulationmaterial includes, by weights: 400-600 parts of gypsum, 250-500 parts of quartz sand, 100-150 parts of heat-insulated light aggregate, 3-5 parts of modified methyl cellulose, 5-10 parts of water reducing agent 6-15 parts of latex powder and 1-15 parts of anti-cracking fiber. Each component is powder or granule, and does not contain the composition that can react with gypsum to produce sodium sulfate. The composite insulation material has the advantages of good reflection insulation, good durability, easy use and low cost. The invention discloses a preparation method of the insulation material, and the method has the advantages of simple process, low thermal conductivity coefficient and high reflectance of sunlight and near-infrared reflectance, and excellent water resistance, weather resistance and durability.
