Abstract

The invention discloses a composite permeability bonding agent for a building outside wall and a preparation method and application thereof. The composite permeability bonding agent comprises 400-600 parts of silica powder and 400-600 parts of a mixture consisting of silicate cement with the fineness of 2500-3500 meshes, silicate cement with the fineness of 200 meshes, an ultramicro building material highly-efficient additive and ordinary silicate cement. The invention further discloses a preparation method of the composite permeability bonding agent and the application of the composite permeability bonding agent as a bonding agent for a building outside wall insulation board. The composite permeability bonding agent for the building outside wall disclosed by the invention has excellent bonding performance and insulation performance, is low in water absorption rate and high in fire resistance, and can effectively improve the anti-aging performance of the insulation board.

Description

technical field [0001] The present invention relates to an adhesive, in particular to a building exterior wall penetrating adhesive and a preparation method thereof. The invention further relates to the application of the building exterior wall composite penetrating adhesive in building exterior wall insulation, which belongs to Adhesives for exterior wall insulation. Background technique [0002] Energy conservation is a major issue facing the world at present, and China, as a developing country with a large energy consumption, pays special attention to it. In 2008, the State Council promulgated and implemented the "Regulations on Energy Conservation of Civil Buildings" (Decree No. 530 of the State Council), which regards building energy conservation as an important national policy in China, and also proposes to achieve 50% building energy efficiency based on building energy consumption from the 20th century to the early 1980s. Target. The Ministry of Construction has suc...
