Description

Technical Field

[0001] The utility model relates to the field of latex paint, in particular to a water-repellent latex paint structure. Background Art

[0002] When latex paint is used on interior walls, indoor personnel will inevitably spill water on the wall when mopping the floor or doing other water-related cleaning work, which will affect the service life of the latex paint. In humid areas, the inner wall will be affected by moisture and will also affect the latex paint on the outside. When latex paint is applied to the exterior wall, there is a probability that rainwater will wash the exterior wall and make it damp. The moisture of the exterior wall will affect the latex paint from the inside to the outside. When the sun shines on the latex paint, the evaporation of moisture between the exterior wall and the latex paint can easily cause the surface of the latex paint to peel and bubble, causing the latex paint to peel and crack due to moisture, thereby reducing its service life.

[0003] Therefore, in order to solve the deficiencies in the prior art, it is necessary to design a water-repellent latex paint structure with a simple structure and good effect. Utility Model Content

[0004] The utility model provides a water-repellent latex paint structure to solve the problems of the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a water-repellent latex paint structure comprises: a mildew-proof layer, a primer layer, a glass fiber reinforced mesh layer, an alkyd resin reflective layer, a latex paint layer and an ethylene-vinyl acetate copolymer waterproof layer, the mildew-proof layer is coated and arranged on the outside of the wall, the primer layer is coated and arranged on the outside of the mildew-proof layer, the glass fiber reinforced mesh layer is bonded and fixed to the outside of the primer layer, the alkyd resin reflective layer is bonded and fixed to the outside of the glass fiber reinforced mesh layer, the latex paint layer is coated and arranged on the outside of the alkyd resin reflective layer, the ethylene-vinyl acetate copolymer waterproof layer is coated and arranged on the outside of the latex paint layer, and matching wavy line concave grooves are provided between the alkyd resin reflective layer, the latex paint layer and the ethylene-vinyl acetate copolymer waterproof layer.

[0006] As a further improvement, protrusions are arranged at intervals on the top surface of the primer layer.

[0007] As a further improvement, hollow microspheres are arranged in the alkyd resin reflective layer, and the diameter of the hollow microsphere particles is less than 200 meshes.

[0008] As a further improvement, the mildew-proof layer is an acrylic modified polyurethane coating.

[0009] According to a further improvement, the primer layer is an epoxy resin coating layer.

[0010] Compared with the prior art, the utility model water-repellent latex paint structure has the following beneficial effects:

[0011] After the bottom mildew-proof layer is applied to the wall, the wall is sealed to reduce the probability of moisture and alkalinity of the wall affecting the outer latex paint layer. The primer layer further improves the connection stability between the mildew-proof layer and the glass fiber reinforced mesh layer. The glass fiber reinforced mesh layer improves the overall strength. The alkyd resin reflective layer can reflect most of the solar heat to prevent the surface of the latex paint from peeling and blistering due to excessive evaporation of moisture in the wall caused by excessive solar temperature. The outermost ethylene-vinyl acetate copolymer waterproof layer has a closed pore structure, does not absorb water, is moisture-proof, and has good water resistance, which protects the inner latex paint layer.

[0012] Matching wavy grooves are arranged between the alkyd resin reflective layer, the latex paint layer and the ethylene-vinyl acetate copolymer waterproof layer to increase the contact area between the layers and further increase the connection strength. BRIEF DESCRIPTION OF THE DRAWINGS
