Thermal insulation material

Abstract

The invention discloses a thermal insulation material. The material is prepared from, by weight, the following raw materials: 40-50 parts of hydrophobic resin, 10-20 parts of polyvinyl alcohol, 100 parts of water, 35-40 parts of white latex, 3-5 parts of a flexibilizer, 15-17 parts of a binder, and 8-10 parts of re-dispersible latex powder. The thermal insulation material has the characteristics of remarkable heat preservation effect, good viscosity, good toughness, light specific gravity, low cost, and has high bonding strength and meets requirements for external wall coating and protection by addition of the white latex.

Description

technical field [0001] The invention relates to the field of materials, in particular to a thermal insulation material. 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.
