DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 - Figure 5 As shown, an environmentally friendly coating anti-cracking thin coating structure includes a glass fiber mesh 1; an anti-cracking coating 20, an elastic coating 21 and a water-based coating 22 are sequentially applied on the glass fiber mesh 1 from the inside to the outside;

[0024] During operation, the above-mentioned technology simply provides a layer of waterproof and crack-resistant mortar layer, which is evenly coated on the wall surface with waterproof and crack-resistant mortar to achieve the effect of resisting cracking of the coating. The anti-cracking ability of the coating is relatively limited. Through the design of the anti-cracking coating 20, the elastic coating 21 and the water-based coating 22, the cracking of the coating can be prevented to a large extent, and the anti-cracking effect of the coating can be improved. An anti-cracking coating 20 is provided on the glass fiber mesh 1. The anti-cracking coating 20 can prevent the coating from cracking, so that the coating applied on the glass fiber mesh 1 is not easy to crack, and the elastic coating 21 and the water-based coating 22 are evenly coated on the anti-cracking coating 20, which further improves the anti-cracking effect of the coating while making the coating surface waterproof and easy to clean.

[0025] Furthermore, the anti-cracking coating 20 includes, from the inside to the outside, a first putty layer 23, a first anti-cracking net 24, a second putty layer 25, an anti-cracking mortar layer 26, a second anti-cracking net 27 and a third putty layer 28, and the first anti-cracking net 24 and the second anti-cracking net 27 are both made of polytetrafluoroethylene material;

[0026] When working, the entire anti-crack coating 20 is composed of three putty layers, one anti-crack mortar layer 26 and two anti-crack nets. The first anti-crack net 24 and the second anti-crack net 27 are added to the putty layer to effectively improve the anti-crack effect, making the coating less likely to crack. The first anti-crack net 24 and the second anti-crack net 27 are both made of polytetrafluoroethylene material, which has the characteristics of acid and alkali resistance and resistance to various organic solvents. It is almost insoluble in all solvents and also has the characteristics of high temperature resistance. The design of two sets of anti-crack nets can improve the anti-crack ability of the anti-crack coating 20. The first putty layer 23 will first be applied to the glass fiber mesh 1 to fix the first anti-crack net 24, and then the second putty layer 25 will be evenly applied to the first anti-crack net 24, and the third putty layer 28 will also be evenly applied to the second anti-crack net 27.

[0027] Furthermore, a plurality of grids are provided on the first anti-crack net 24 and the second anti-crack net 27, and the first anti-crack net 24 and the second anti-crack net 27 are arranged in a staggered manner;

[0028] During operation, the first anti-crack net 24 and the second anti-crack net 27 are both placed obliquely on the first putty layer 23 and the anti-crack mortar layer 26, and the excess parts are cut off, and the first anti-crack net 24 and the second anti-crack net 27 are arranged alternately, so that the grids on the first anti-crack net 24 and the second anti-crack net 27 become denser, thereby making the overall anti-crack ability stronger and the anti-crack effect better.

[0029] Furthermore, a layer of anti-cracking mortar layer 26 is applied on the second putty layer 25, and the anti-cracking mortar layer 26 is located between the second putty layer 25 and the second anti-cracking net 27;

[0030] During operation, an anti-cracking mortar layer 26 is evenly applied between the first anti-cracking net 24 and the second anti-cracking net 27. The anti-cracking mortar layer 26 is a mortar made of anti-cracking agent made of polymer emulsion and admixture, cement and sand mixed with water in a certain proportion, which can meet a certain deformation and remain without cracking. It is also a high-quality environmentally friendly material with high tensile strength, easy construction and anti-freezing.

[0031] Further, the elastic coating 21 is formed by evenly applying the elastic coating;

[0032] When working, the elastic coating 21 is a latex paint with elasticity, flexibility and ductility, which can effectively cover the cracks in the wall and will not cause cracks in the coating due to the cracks in the wall. At the same time, it also has certain water resistance and stain resistance and is more textured.

[0033] Further, the water-based coating 22 is formed by evenly applying the anti-cracking water-based paint;

[0034] When working, water-based paint does not contain more harmful substances compared to oil paint, so it is more environmentally friendly, less polluting and odorless. At the same time, it can also make the surface of the coating less likely to crack due to scratches, and the surface is easy to clean.

[0035] Working principle: In the above technology, only a layer of waterproof and crack-resistant mortar layer is simply provided. The waterproof and crack-resistant mortar layer is evenly coated on the wall surface with waterproof and crack-resistant mortar to achieve the effect of resisting cracking of the coating. The anti-cracking ability of the coating is relatively limited. Through the design of the anti-cracking coating 20, the elastic coating 21 and the water-based coating 22, the cracking of the coating can be prevented to a large extent, and the anti-cracking effect of the coating can be improved. An anti-cracking coating 20 is provided on the glass fiber mesh 1. The anti-cracking coating 20 can prevent the coating from cracking, so that the coating applied on the glass fiber mesh 1 is not easy to crack, and the elastic coating 21 and the water-based coating 22 are evenly coated on the anti-cracking coating 20, which further improves the anti-cracking effect of the coating while making the coating surface waterproof and easy to clean.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
