[0012] As a preferred embodiment of the heavy-weight plaster putty coating structure with high-efficiency waterproof and moisture-proof performance of the present invention, the cement nails are 2.5×25mm.

[0013] As a preferred embodiment of the heavy-weight plaster putty coating structure with high-efficiency waterproof and moisture-proof performance of the present invention, four cement nails are provided, and the four cement nails are respectively located at the four corners of the alkali-resistant glass fiber mesh cloth.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By arranging an alkali-resistant glass fiber mesh cloth on one side of the inner waterproof putty coating, fixing the four corners of the alkali-resistant glass fiber mesh cloth with cement nails, and then filling the alkali-resistant glass fiber mesh cloth with a waterproof adhesive layer, the adhesion between the alkali-resistant glass fiber mesh cloth and the inner waterproof putty coating can be increased, thereby improving the connection strength between the mortar leveling layer, the inner waterproof putty coating and the wall base layer, and reducing the warping and falling phenomenon.

[0016] By using the waterproof adhesive layer to fill the 1-2mm protruding from the alkali-resistant glass fiber mesh cloth, the waterproof adhesive layer can form an additional protective layer on the alkali-resistant glass fiber mesh cloth, which not only improves the service life of the alkali-resistant glass fiber mesh cloth, but also further improves the waterproof and moisture-proof effect. At the same time, the protruding portion of the waterproof adhesive layer will also cover the nail heads of the cement nails, so that the outer plaster gypsum layer and the outer waterproof putty coating will not be affected by the protruding nail heads of the cement nails during painting, thereby ensuring the overall beauty.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-3 The present invention provides the following technical solutions: a heavy-duty plastering gypsum putty coating structure with high-efficiency waterproof and moisture-proof performance, comprising a wall base 1, a mortar leveling layer 2 is arranged on one side of the wall base 1, an inner waterproof putty coating 3 is arranged on one side of the mortar leveling layer 2, an alkali-resistant glass fiber mesh cloth 4 is arranged on one side of the inner waterproof putty coating 3, a waterproof adhesive layer 5 is arranged on one side of the alkali-resistant glass fiber mesh cloth 4, a plastering gypsum layer 6 is arranged on one side of the waterproof adhesive layer 5, an outer waterproof putty coating 7 is arranged on one side of the plastering gypsum layer 6, and cement nails 8 are penetrated through the surfaces of the wall base 1, the mortar leveling layer 2, the inner waterproof putty coating 3 and the alkali-resistant glass fiber mesh cloth 4; It should be noted that the arrangement of the inner waterproof putty coating 3, the alkali-resistant glass fiber mesh cloth 4, the waterproof adhesive layer 5, the plastering gypsum layer 6, and the outer waterproof putty coating 7 can effectively improve the waterproof and moisture-proof effect of the heavy plastering gypsum putty coating structure; What is more important to note is that before the coating is applied to the wall base layer 1, the wall base layer 1 needs to be processed first to ensure that the wall base layer 1 is flat, oil-free and powder-free. The plaster layer 6 is located between the waterproof adhesive layer 5 and the outer waterproof putty coating 7, which can play a role in leveling, enhancing the wall strength and providing a certain thickness. The thickness of the plaster layer 6 can be adjusted according to actual conditions.

[0021] Preferably, the mortar leveling layer 2 is a polymer cement waterproof mortar, and the thickness of the mortar leveling layer 2 is 3-5 mm, and the thickness of the inner waterproof putty coating 3 is 5-10 mm; It should be noted that polymer cement waterproof mortar is a mortar made of cement, polymer dispersion as binder and sand. After the polymer cement mortar hardens, the polymer in the mortar leveling layer 2 can effectively close the connected pores, increase the density and crack resistance of the mortar leveling layer 2, thereby improving the impermeability and impact resistance of the mortar.

[0022] Preferably, the weaving angle of the alkali-resistant glass fiber mesh cloth 4 is 90 degrees, and the thickness of the alkali-resistant glass fiber mesh cloth 4 is 0.5-1 mm.

[0023] During specific use, an alkali-resistant glass fiber mesh cloth 4 is arranged on one side of the inner waterproof putty coating 3, and the four corners of the alkali-resistant glass fiber mesh cloth 4 are fixed with cement nails 8, and then the alkali-resistant glass fiber mesh cloth 4 is filled with a waterproof adhesive layer 5, so that the adhesion between the alkali-resistant glass fiber mesh cloth 4 and the inner waterproof putty coating 3 can be increased, thereby improving the connection strength between the mortar leveling layer 2, the inner waterproof putty coating 3 and the wall base layer 1, and reducing the warping and falling phenomenon.

[0024] Preferably: the waterproof adhesive layer 5 is a mineral adhesive layer, and the thickness of the waterproof adhesive layer 5 is 2.5-5.5 mm, the waterproof adhesive layer 5 is 1-2 mm higher after filling the holes of the alkali-resistant glass fiber mesh cloth 4, the cement nail 8 is 2.5×25 mm, four cement nails 8 are provided, and the four cement nails 8 are respectively located at the four corners of the alkali-resistant glass fiber mesh cloth 4, and the nail head part of the cement nail 8 is located between the alkali-resistant glass fiber mesh cloth 4 and the waterproof adhesive layer 5; It should be noted that the nail head of the cement nail 8 needs to be larger than the hole size on the alkali-resistant glass fiber mesh cloth 4, so that the nail head can be used to press the alkali-resistant glass fiber mesh cloth 4 to achieve fixation. The cement nail 8 is made of high-strength steel and the surface is rust-proofed to improve service life and safety. It should be noted that if a 0.5 mm thick alkali-resistant glass fiber mesh cloth 4 is selected, the thickness of the waterproof adhesive layer 5 is between 1.5-2.5 mm. Since the alkali-resistant glass fiber mesh cloth 4 has holes, when the waterproof adhesive layer 5 fills the holes, there will be an extra 1-2 mm of alkali-resistant glass fiber mesh cloth 4 wrapped.

[0025] During specific use, by using the waterproof adhesive layer 5 to fill the 1-2 mm protruding from the alkali-resistant glass fiber mesh cloth 4, the waterproof adhesive layer 5 can form an additional protective layer on the alkali-resistant glass fiber mesh cloth 4, thereby further improving the waterproof and moisture-proof effect. At the same time, the protruding part will also cover the nail head of the cement nail 8, so that the outer plaster gypsum layer 6 and the outer waterproof putty coating 7 will not be affected by the protruding nail head of the cement nail 8 during painting, thereby ensuring the overall beauty.

[0026] Working principle: First, an alkali-resistant glass fiber mesh cloth 4 is arranged on one side of the inner waterproof putty coating 3, and the four corners of the alkali-resistant glass fiber mesh cloth 4 are fixed with cement nails 8, and then the alkali-resistant glass fiber mesh cloth 4 is filled with the waterproof adhesive layer 5, so that the adhesion between the alkali-resistant glass fiber mesh cloth 4 and the inner waterproof putty coating 3 can be increased, thereby improving the connection strength between the mortar leveling layer 2, the inner waterproof putty coating 3 and the wall base layer 1, and reducing the warping and falling phenomenon. In addition, since the waterproof adhesive layer 5 is 1-2mm higher after filling with the alkali-resistant glass fiber mesh cloth 4, the waterproof adhesive layer 5 can form an additional protective layer on the alkali-resistant glass fiber mesh cloth 4, thereby further improving the waterproof and moisture-proof effect. At the same time, the raised part will also cover the protruding nail head of the cement nail 8, so that the outer plaster gypsum layer 6 and the outer waterproof putty coating 7 will not be affected by the protruding nail head of the cement nail 8 during painting, thereby ensuring the overall beauty.

[0027] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
