Problems solved by technology

[0003] Traditional exterior wall coatings are generally hard and flat. During use, the exterior wall will inevitably be squeezed, collided, and rubbed by external objects, resulting in excessive local stress and weakened local strength. As a result, it is easy to cause local peeling and peeling, thus losing the protective effect on the outer wall of the area

Embodiment

[0045] see figure 1 , a building exterior wall coating with anti-falling off, comprising a fracture buffer layer 1 coated on the surface of the exterior wall, the outer surface of the fracture buffer layer 1 is fixedly connected with a grid cloth 2, the fracture buffer layer 1 and a grid The surface layer 3 is fixedly connected between the cloth 2, and the inside of the crack buffer layer 1 is evenly filled with a plurality of tearing and replenishing particles. The coating preparation method is as follows:

[0046] S1. Prepare the exterior wall paint, and freeze the tearing and replenishing particles at the same time;

[0047] S2, uniformly mixing a part of the exterior wall paint and the tearing refill particles to obtain a mixture;

[0048] S3, evenly coating the mixture on the surface of the exterior wall, and forming a complete solid coating after drying;

[0049] S4, covering the grid cloth 2 on the surface of the above-mentioned solid coating, and then coating another...

Abstract

The invention discloses an anti-falling building outer wall coating, and belongs to the field of building outer wall coatings. A solid coating can be broken through heating change of tearing and refilling particles, a crack buffering layer with blocks and powder is formed, and when the crack buffering layer is subjected to external acting force, the crack buffering layer is stressed to generate an internal migration process, so that acting force is transmitted to the periphery, the force is dispersed, weakened and buffered, and the stressed part is effectively protected against peeling and falling due to damage; and when the external acting force is excessively large and is dispersed and weakened through the crack buffering layer, the remaining acting force reaches the tearing and refilling particles, an outer spherical shell is stressed and broken, a repairing liquid flows out and fills all gaps of the crack buffering layer, the broken crack buffering layer is repaired into a hard whole again, the crack buffering layer recovers to a certain hardness to resist external acting force, and a double compression resistance effect of the crack buffering layer is achieved.

Description

technical field [0001] The invention relates to the field of building exterior wall coatings, in particular to an anti-shedding building exterior wall coating. Background technique [0002] Exterior wall paint is used to paint the exterior wall of a building to form a coating material that can play a certain role. It is used to protect the exterior walls of buildings and improve the service life of exterior walls, such as anti-corrosion coatings, thermal insulation coatings, waterproof coatings, etc. [0003] Traditional exterior wall coatings are generally hard and flat. During use, the exterior wall will inevitably be squeezed, collided, and rubbed by external objects, resulting in excessive local stress and weakened local strength. As a result, it is easy to cause local peeling and peeling, thus losing the protective effect on the outer wall of the area. Contents of the invention [0004] 1. Technical problems to be solved [0005] In view of the problems existing in...
