Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building coatings, and particularly relates to a bounceable colorful imitation stone coating and a preparation method thereof. BACKGROUND

[0002] In the field of building decoration, natural stone is favored as a high-end material, which is elegant and natural, and is suitable for indoor and outdoor decoration of various buildings. However, with the economic development, China pays more and more attention to environmental protection, and the relevant regulations are becoming more and more strict, which makes the cost of mining, processing and transportation of natural stone rise continuously, and limits its application in the field of building decoration. At the same time, China's emphasis on energy saving promotes the development of building external wall insulation technology, and the setting of insulation base on the building external wall is popularized. However, using natural stone for decoration on the basis of the insulation base has a complex construction process and high construction difficulty, which also affects the application of natural stone in the field of building decoration. Based on this background, imitation stone coatings with good waterproof and crack resistance, acid and alkali resistance, good weather resistance and other excellent properties have emerged. It is rich in color, strong in simulation, simple in construction, and can be sprayed on the building external wall, with a simulation degree of 99% to natural stone, and is not limited by the shape and location of the building.

[0003] Among the imitation stone coatings, the most used are colorful imitation stone coatings and natural stone paint. Natural stone paint formula adds natural color sand, so it has a natural advantage in simulation degree with natural stone. However, similarly, color sand mine is an irreversible resource, and the state has gradually paid attention to and controlled it, so the natural color sand resource as the raw material of the stone paint has been limited. Under this circumstance, colorful imitation stone coatings have gradually attracted the attention of the market. However, due to the reasons of raw materials and formula, the simulation degree of colorful imitation stone coatings is still different from that of stone paint, which limits its application in many aspects. At the same time, the high price of materials such as magnesium lithium silicate in its formula limits its large-scale promotion, and even there are cheap material and performance substandard colorful imitation stone coating products on the market. Therefore, how to reduce the production cost while ensuring the quality of colorful imitation stone coatings is an important optimization direction of the product.

[0004] In addition, as a coating, the strength of colorful imitation stone coating is quite different from that of natural stone, and it is easy to be damaged when colliding with hard objects, especially when used in the lower part of the building, there is the disadvantage of being knocked out of the pit. If the coating can bounce back and restore to its original state after being knocked, it will be a major breakthrough in the application of colorful products.

[0005] Therefore, it is urgent to find a technical solution to solve the defects existing in the prior art. SUMMARY
