Abstract

The invention relates to a waterproof ventilated type aerated concrete block surfactant which simultaneously has better adhesive property, moisture retention property, waterproof property, weather resisting property and air permeability, can solve the difficult problem bothering people for a long time in the application of aerated concrete blocks, is suitable for large-scale popularization and application and has remarkable economic benefit.

Description

technical field [0001] The invention belongs to the technical field of building materials, and more specifically relates to a PTB waterproof and air-permeable air-entrained concrete block interface agent and its application method. Background technique [0002] The interface agents of air-entrained concrete blocks currently on the market have problems to varying degrees, which lead to cracking and hollowing of the walls of air-entrained concrete blocks, which limits the engineering application of air-entrained concrete blocks to a certain extent. Aiming at the cracking and hollowing phenomenon of aerated concrete block walls, many scientific and technical personnel at home and abroad have studied many methods and supporting materials for improving the interface of aerated concrete block walls according to the material characteristics of aerated concrete blocks, and have achieved certain results. Progress. At present, there are few studies on interface agents for air-entrain...
