Description

Technical Field

[0001] The utility model relates to the technical field of latex paint layers, in particular to a weather-resistant coating structure of latex paint. Background Art

[0002] Latex paint is a type of organic paint. It is a type of water-based paint made from synthetic resin emulsion as the base material with the addition of pigments, fillers and various additives. The weather resistance of the coating refers to the coating's tolerance to various physical, chemical or biological factors after long-term use under different external environmental conditions. Generally speaking, a coating with strong weather resistance can extend the product's service life, maintain good performance, and reduce equipment maintenance costs. It is one of the very important quality indicators in coating processing.

[0003] With the rapid development of the times, the construction industry at home and abroad attaches great importance to the development and application of green and energy-saving building materials. However, traditional latex paints have disadvantages such as poor durability, mildew resistance, crack resistance, and flame retardancy. Therefore, traditional latex paints have gradually been unable to meet the current painting needs. Utility Model Content

[0004] In order to overcome the shortcomings mentioned in the above background technology, the utility model provides a weather-resistant coating structure of latex paint to solve the above problems.

[0005] The technical solution of the utility model is: a weather-resistant coating structure of latex paint, comprising a primer layer, a base layer, an anti-cracking layer, a flame-retardant paint layer and a topcoat layer, wherein the primer layer is provided with a base layer, the base layer is provided with an anti-cracking layer, the anti-cracking layer is provided with a flame-retardant paint layer, and the flame-retardant paint layer is provided with a topcoat layer.

[0006] In one embodiment, the primer layer is a mildew-proof and alkali-resistant primer, and the thickness of the primer layer is 0.8-1.5 mm.

[0007] In one embodiment, the base layer is made of ultrafine titanium dioxide, and the thickness of the base layer is 0.8-1.5 mm.

[0008] In one embodiment, the anti-cracking layer is made of polypropylene fiber, and the thickness of the anti-cracking layer is 0.3-0.6 mm.

[0009] In one embodiment, the flame retardant paint layer is made of magnesium hydroxide nano-modified material, and the thickness of the flame retardant paint layer is 0.8-1.6 mm.

[0010] In one of the embodiments, nano titanium dioxide particles are also included. The topcoat layer contains nano titanium dioxide particles, and the thickness of the topcoat layer is 0.5-0.8 mm.

[0011] Beneficial effects: 1. The utility model first applies a primer layer, and uses the mildew-proof and alkali-resistant primer to isolate the wall from the latex paint surface, thereby reducing the possibility of latex paint peeling and cracking due to moisture, and then uses a polypropylene fiber anti-cracking layer to increase the flexibility of the coating, further preventing the coating from cracking, thereby extending the service life of the latex paint and improving the weather resistance of the latex paint to adapt it to new painting needs.

[0012] 2. The utility model provides a base layer of ultrafine titanium dioxide to enhance the bonding strength between structures, thereby improving the overall structural strength and ensuring the firmness of latex paint. The flame retardant paint layer of magnesium hydroxide nano-modified material is provided to effectively inhibit the spread of flames, thereby improving safety. Finally, nano titanium dioxide particles are added to the topcoat layer to improve the anti-aging property of the latex paint and further extend the service life of the coating.

[0015] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0016] Embodiment: A weather-resistant coating structure of a latex paint, such as Figure 1 As shown, it includes a primer layer 1, a base layer 2, an anti-cracking layer 3, a flame retardant paint layer 4 and a topcoat layer 5. The primer layer 1 adopts a mildew-proof and alkali-resistant primer, and the mildew-proof and alkali-resistant primer can isolate the wall from the latex paint surface. The thickness of the primer layer 1 is 0.8-1.5mm. The upper surface of the primer layer 1 is provided with a base layer 2, and the base layer 2 adopts ultrafine titanium dioxide. The base layer 2 of ultrafine titanium dioxide can enhance the bonding strength and structural strength. The thickness of the base layer 2 is 0.8-1.5mm. An anti-crack layer 3 is provided on the upper surface, and the anti-crack layer 3 is made of polypropylene fiber. The polypropylene fiber can increase the flexibility of the coating. The thickness of the anti-crack layer 3 is 0.3-0.6mm. A flame retardant paint layer 4 is provided on the upper surface of the anti-crack layer 3. The flame retardant paint layer 4 is made of magnesium hydroxide nano-modified material. The magnesium hydroxide nano-modified material can effectively inhibit the spread of flames. The thickness of the flame retardant paint layer 4 is 0.8-1.6mm. A topcoat layer 5 is provided on the upper surface of the flame retardant paint layer 4.

[0017] like Figure 1As shown, nano titanium dioxide particles 6 are also included. The topcoat layer 5 is provided with nano titanium dioxide particles 6. The nano titanium dioxide particles 6 will improve the aging resistance of the latex paint, and the thickness of the topcoat layer 5 is 0.5-0.8 mm.

[0018] When latex paint is needed, first apply a primer layer 1 with a thickness of 0.8-1.5mm on the putty wall. The mildew-proof and alkali-resistant primer can isolate the wall from the latex paint surface, thereby reducing the possibility of peeling and cracking of the latex paint due to moisture. Then apply a base layer 2 with a thickness of 0.8-1.5mm. The base layer 2 with ultrafine titanium dioxide can enhance the bonding strength and structural strength, thereby ensuring the firmness of the latex paint. Then apply a 0.3-0.6mm thick anti-cracking layer 3, which uses polypropylene fiber. The anti-cracking layer 3 can increase the flexibility of the coating, thereby effectively preventing the coating from cracking. Then a flame retardant paint layer 4 with a thickness of 0.8-1.6 mm is applied. The flame retardant paint layer 4 made of magnesium hydroxide nano-modified material has good heat insulation and flame retardant properties, and can effectively inhibit the spread of flames, thereby improving safety. Finally, a topcoat layer 5 with a thickness of 0.5-0.8 mm is applied. The nano titanium dioxide particles 6 on the topcoat layer 5 will greatly improve the aging resistance of the latex paint and further extend the service life of the coating.
