Problems solved by technology

[0005] Traditional real stone paint, due to the large void ratio, has poor heat insulation effect on the wall
In the existing technology, the reflection and heat insulation function is realized by adding glass microspheres to the composition of the real stone paint. However, the general reflection and heat insulation real stone paint often adopts the construction method of spraying, and the density of the hollow glass microspheres is relatively high. Low, with spraying construction, a large number of hollow glass beads will not be sprayed on the wall and will be scattered in the air, resulting in large losses, and the high spray pressure during construction on the site will also cause the hollow glass beads to break and lose. Therefore, spraying construction, Hollow glass microspheres have particularly high material consumption and loss rates
At the same time, the spraying construction of real stone paint has high requirements for construction workers. During spraying, it is easy to cause the wall surface to bloom due to the immature construction skills of construction workers, and it has high requirements for the construction environment.
If ordinary spraying real stone paint is directly applied by wiping, the construction effect will not be good, and it is prone to blooming. This is because the spraying of real stone paint requires the state of the paint to be fluffy and have large gaps, and the fluidity should not be too good, so that it is not easy to block when spraying. gun, not easy to hang gun
[0006] In addition, spraying construction has high requirements on the construction skills and collaborative construction ability of construction personnel. Different construction conditions such as spraying techniques and construction air pressure will cause the wall to bloom
At the same time, spraying construction cannot be carried out in windy weather

Background technique [0002] In recent years, the real estate industry has developed rapidly. As a new type of coating method, colored sand and real stone paint have attracted great attention from the industry. [0003] Real stone paint is mainly made of high molecular polymer, natural colored sand and related additives. It is as hard as stone after drying and curing, and has the effect of imitating natural real stone. It has strong adhesion, weather resistance, water resistance, and is easy to repair; the coating of real stone paint After the layer is dry and solid, it is very hard and cannot be picked by nails. It is mainly used for building decoration, terrazzo aggregate, etc. Because of its unique appearance and performance,...
