Insulation Materials

Abstract

The invention provides a heat preservation material, which is prepared from the following raw materials by weight: 20-30 parts of hydrophobic resin, 4-7 parts of polyvinyl alcohol, 35-50 parts of water, 25-32 parts of white latex, 1.3-2.6 parts of a toughening agent, 8-12 parts of a binder, and 3-6 parts of redispersible latex powder. The heat preservation material provided by the invention has significant heat preservation effect, good viscosity, good toughness, light specific gravity and low cost, and is added with white latex, thus having high bonding strength and meeting the requirements of external wall coating.

Description

technical field [0001] The invention relates to the field of construction, 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. Contents of the invention [0003] The invention provides a thermal insulation ...
