AI Technical Summary

Problems solved by technology

Its shortcomings are that the strength is not high, the self-protection is not strong, and the anti-cracking effect is poor.
However, most of the domestic waterproof coatings used for roofs and exterior walls have single functions and poor comprehensive performance, which cannot meet the requirements of building energy conservation.

Description

technical field [0001] The invention relates to the technical field of waterproof and heat-preserving materials, in particular to a waterproof and heat-retaining coating for building exterior walls and a preparation method thereof. Background technique [0002] With the improvement of people's quality of life, people pay more and more attention to the waterproof performance of buildings. At present, problems such as roof leaks, leaky underground works, indoor kitchen leaks, leakage of external wall plastering cracks, and wet long hairs on the walls are more prominent. , not only disrupted people's normal life, work, and production order, but also caused huge economic losses. The occurrence of leakage will directly endanger the structure of the building, and then affect its life; the housing will be moldy and smelly due to long-term damp, which will directly affect the health and quality of life of residents; and for enterprise factories, etc., it will damage public facilitie...
