Exterior wall thermal insulation foaming putty

Abstract

The invention discloses a novel external wall heat insulating foaming putty, which is mainly formed by the following materials with percentage by weight, 15-25% H2O, 0.05-0.15 preservative agent, 0.8-1.5% acrylate, 0.2-0.5% dispersing agent, 1-1.5% anti-freeze agent, 0.5-2% NH4 HCO3, 1-2% 12 carbon betulin, 3-5% wood fiber or polypropylene fiber, 0.4-0.6% water-loss reducer, 10-20% propyl benzene emulsion, 20-30% CaCO3 powder, 30-40% talcum powder, 3-5% polyphenylene particle and 0.5-1.5% wax emulsion. The external wall heat insulating foaming putty adopts the self-foaming principle, provides heat insulating effect through adding polyphenylene particle in heat-insulating mortar, has excellent heat insulating effect, and can be extensively applied on the external walls of buildings.

Description

technical field [0001] The invention relates to an external wall thermal insulation material, in particular to a novel external wall thermal insulation foam putty. Background technique [0002] Building energy consumption is the largest energy consumer in my country. In the building enclosure structure, the building exterior wall accounts for more than 1 / 3 of the total energy consumption of the enclosure structure. Exterior wall insulation is the focus of building energy conservation. highly valued. In recent years, a series of policies, regulations and technical standards have been promulgated, such as the national standard JG149-2003 "expanded polystyrene board thin plaster external wall external insulation system" and the industry standard JC158-2004 "rubber powder polystyrene particle external insulation system", These technologies have been widely used because of their advantages of reliable thermal insulation effect and mature technology. [0003] The advantage of the...

Problems solved by technology

Among them, EPS particle mortar, as an external wall insulation material, has good thermal insulation performance. EPS particle insulation mortar is composed of inorganic adhesive, organic binder, water retaining agent, EPS particles and other light aggregates. However, at present, EPS insulation mortar has problems such as difficult construction, water seepage, cracking, poor strength, and poor adhesion, which have caused dissatisfaction among users.
