Description

technical field [0001] The invention belongs to the technical field of preparation of exterior wall thermal insulation coatings, in particular to an anti-cracking agent for external wall thermal insulation anti-cracking waterproof coatings and a preparation method thereof. Background technique [0002] At present, traditional brick and tile building materials are limited due to competition with farmland, energy consumption, excessive weight, increased transport capacity, and poor heat insulation. They are replaced by frame light structures and steel frame structures. There is a thermal insulation problem for these structures. Even if the brick-concrete structure needs to achieve a certain thermal insulation effect, there is also a problem of wall thickness. In this case, thermal insulation coatings came into being. Applying thermal insulation coatings and adopting strict construction procedures can achieve the same thermal insulation effect and reduce wall thickness. It is a...
