Abstract

The invention discloses a temperature preservation and heat insulation composite on an exterior wall of a building and a construction method thereof; the composite comprises 1 weight portion of composite powders and 0.06 to 0.120 portions of polyphenylene particles. Before construction, the mixing ratio of dry-mixed mortar composite, the polyphenylene particles and water satisfies that composite powders: polyphenylene particles: water is equal to 1(kg): (60 to 120)(g): (1.2 to 1.4)(kg). The ratio of each component in the temperature preservation and heat insulation composite material of the exterior wall provided by the invention is reasonable, leading to excellent temperature preservation and heat insulation effects, and high bonding strength and good chemical performance of the heat insulation material. At the same time, the composite has waterproof function. The large amount of added fly ash of the invention provides a new path for the application of fly ash in the exterior wall temperature preservation system. The application of regenerated polyphenylene foams is a new attempt to make the waste to the worth in the temperature preservation and heat insulation system and also eliminates the harmful environmental pollution caused by the regenerated polyphenylene foams.

Description

technical field [0001] The invention relates to a thermal insulation composite material for building exterior walls, in particular to a thermal insulation and energy-saving material prepared by using recycled polyphenylene particles and fly ash. technical background [0002] The thermal insulation and waterproof materials and construction techniques used in modern buildings have become important indicators for evaluating the scientific and technological content of buildings. Among the existing heat insulating materials, the Chinese invention patent with publication number CN1454959A discloses a large amount of fly ash waterproof and heat insulating material and its construction method.
