Problems solved by technology

The technical solution of ZL02133287.8 has the advantages of low construction cost, convenient construction, and anti-aging. However, because the formula contains asbestos velvet, which is a harmful substance, people are very cautious about this substance, so that the application of this coating In addition, due to the poor water resistance of polyvinyl alcohol (PVA), although it is modified with sodium silicate, its water resistance is still unsatisfactory; the technical scheme of ZL02145516.3 has low cost and easy construction. However, since the main raw materials used as heat insulation are waste polystyrene foam and expanded perlite, the density of waste polystyrene foam cannot be guaranteed, and waste polyphenylene foam is recycled, and its density cannot be controlled, especially When the particle diameter is less than 3mm, not only the heat insulation effect is very poor, but also the compressive strength becomes very fragile; although ZL98122731. thermal insulation effect

Abstract

The present invention relates to a double-component gypsum base polystyrene foam particle heat-insulating coating for thermal insulation of building internal wall, external wall and roof. Its composition includes (by weight portion) 2-6 portions of polystyrene foam particle, 4-10 portions of modified calcium oxide, 4-10 portions of synthetic resin emulsion, 35-45 portions of water, 0.1-1.5 portions of thickening agent, 0.1-1.5 portions of modifying agent, 0.1-2 portions of reinforcing fibre, 0.5-1.5 portions of delayed coagulant, 30-50 portions of calcined gypsum powder and 0.1-0.3 portion of foaming agent. Besides, said invention also provides its preparation method.

Description

technical field [0001] The invention relates to a two-component gypsum-based polystyrene foam particle thermal insulation coating, which is used for thermal insulation of the inner and outer walls and roofs of buildings, and belongs to the technical field of thermal insulation coatings for buildings. Background technique [0002] Aiming at advocating and advocating an energy-saving society, the Ministry of Construction of my country has issued relevant regulations requiring the implementation of thermal insulation measures for residential buildings. Therefore, thermal insulation materials that are economical, easy to use, and have ideal thermal insulation effects are becoming more and more popular among people. attention and favor. In this regard, it can be seen from the house insulation coating disclosed in Chinese Patent No. ZL02133287.8, the composite insulation coating disclosed in ZL02145516.3, and the information on a waterproof coating disclosed in ZL98122731.7. The t...
