Abstract

The invention relates to a wall heat insulation coating. The wall heat insulation coating is characterized by being prepared from the following components in parts by weight: 40 to 50 parts of styrene-acrylic emulsion, 10 to 12 parts of rock wool, 4 to 8 parts of heat insulation light aggregate, 10 to 20 parts of sericite powder, 0.5 to 2 parts of dispersant, 0.5 to 3 parts of wetting agent, 0.5 to 2.5 parts of thickener, 1 to 6 parts of defoamer, 0.5 to 2.5 parts of film forming additive, 1 to 3 parts of ammonia water, and 40 to 50 parts of water. The wall heat insulation coating has the beneficial effects that the heat insulation and isolation properties are good, the coating surface is dense, the coating interior is loose, the waterproof property and the heat insulation and isolation properties can be effectively combined, and the heat stability is high; the wall heat insulation coating is a composite wall heat insulation material with excellent property, and can be applied to multiple fields, especially building outer walls.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a thermal insulation coating for walls. Background technique [0002] In recent years, due to the development of exterior wall heat insulation technology, the heat insulation coating of building walls has gradually changed from interior walls to exterior walls. Energy is the premise and foundation for the survival and development of human society, and it provides the driving force for economic development. With the progress and development of science and technology, the contradiction between the increase of energy demand and the relative decrease of energy supply in human society is becoming more and more serious. At present, the energy utilization rate in the world is generally low, which seriously restricts the sustainable development of human society in the 21st century. The development of new green energy and the improvement of energy utilization have become ...
