[0028] Indoor dust reduction refers to measures taken to reduce the concentration of dust and suspended particulate matter in the indoor environment. The current main method of indoor dust reduction is to use air purifiers for purification and filtration. However, air purifiers often need to run continuously to effectively reduce dust, so the energy consumption is high. In addition, air purifiers will generate noise during operation, affecting the quietness and comfort of the room.

[0029] At present, in order to achieve the dust removal effect, a dust-proof coating has also appeared. The principle of this dust-proof coating is to reduce the accumulation and adsorption of surface dust. Specifically, it reduces the accumulation and adsorption of dust by reducing static electricity, improving surface smoothness, and improving wear resistance. It can reduce the accumulation of dust and dirt, making cleaning and maintenance easier. This process does not require equipment investment and has low cost.

[0030] Although this dust-proof coating can reduce the accumulation of dust on the coated surface, dust will still exist in a large amount in the space, thus affecting the indoor air environment.

[0031] To this end, the embodiment of the utility model proposes a coating structure, including a base layer, a water-absorbing material layer and a surface layer arranged in sequence from the inside to the outside, and the water-absorbing material layer is selected from one of a polymer water-absorbing resin layer, a zeolite layer, and an alumina gel layer.

[0032] High molecular absorbent resin is a water-swellable high molecular polymer containing strong hydrophilic groups such as carboxyl and having a certain degree of cross-linking. It has the ability to absorb and retain water, and the amount of water absorbed can reach more than a thousand times its own weight. Zeolite is an aluminum silicate mineral with a microporous structure that can absorb and release water. Alumina gel is a porous metal oxide material with a high water absorption capacity.

[0033] The coating structure of the utility model includes a water-absorbing material layer. When the humidity of the space environment is high, the water vapor in the air collides with the dust particles to form agglomeration, and the formed agglomerated particles are adsorbed by the water-absorbing material layer, thereby reducing the dust content in the air; when the humidity of the space environment is low, the water in the water-absorbing material layer evaporates into water vapor, and the water vapor and dust agglomerate to achieve the effect of dust reduction. Therefore, the coating structure of the utility model can achieve the effect of improving the indoor air environment through the adsorption of the water-absorbing material layer and the evaporation of water vapor to reduce dust.

[0034] It should be noted that the base layer of the utility model can be selected according to the application scenario of the coating. When the coating is applied to the wall, the base layer can be a wall curing agent, latex paint, etc. The surface layer can also be selected from one of paint, topcoat, and wallpaper according to the application scenario of the coating structure. The thickness can be selected between 0.2-20mm.

[0035] In the embodiment of the present invention, the thickness of the water-absorbing material layer is 0.1-1 mm.

[0036] In the embodiment of the utility model, the particle size of the water-absorbing material layer is 50-300 meshes. The water-absorbing material with a particle size in this range has a larger specific surface area and can enhance the water absorption capacity.

[0037] In an embodiment of the present invention, the coating structure further comprises an electrostatic adsorption layer, and the electrostatic adsorption layer is arranged on the inner side of the water-absorbing material layer.

[0038] Since dust molecules may contain polar molecules, these molecules may be charged under certain conditions and thus can be adsorbed by the electrostatic field. Therefore, the utility model provides an electrostatic adsorption layer to utilize the charge attraction to adsorb and settle the dust molecules, thereby further improving the indoor air environment.

[0039] In an embodiment of the present invention, the electrostatic adsorption layer is selected from one of a tourmaline layer, a polyamide fiber layer, and an electret material layer.

[0040] The crystal structure of tourmaline determines that it has the characteristics of permanent charge and permanent positive and negative poles. The test results show that tourmaline can emit 0.16pA of current permanently. The positive pole absorbs negative ions in the air and stores them inside the crystal. The excess negative ions can be released from the negative pole, forming the characteristic of permanent discharge. Therefore, the surface of tourmaline can generate an electrostatic field, thereby attracting and capturing nearby charged particles, including dust particles. In addition, there are many tiny holes and cracks on the surface of tourmaline. These structures can physically capture dust particles, especially those smaller particles.

[0041] The surface of polyamide fiber (nylon) carries static charge. When the polyamide fiber with static charge comes into contact with dust particles in the air, the static field will attract the dust particles. In addition, there are grooves, holes or fluff on the surface of polyamide fiber. These structures can increase the contact area between the fiber and the dust particles, thereby improving the adsorption efficiency.

[0042] Electret material is a material that can maintain electrostatic charge for a long time. This electrostatic property enables the electret material to attract and adsorb dust particles of opposite charge. Commonly used electret materials include polymer materials, such as polyethylene, polypropylene, polyester, etc., and inorganic materials, such as silicon dioxide, aluminum oxide, etc. The utility model does not make specific restrictions on the selection of electret materials.

[0043] In the embodiment of the present invention, the thickness of the electrostatic adsorption layer is 0.1-0.4 mm.

[0044] In the embodiment of the utility model, the particle size of the electrostatic adsorption layer is 100-600 meshes. The electrostatic adsorption material with a particle size in this range has a larger specific surface area and can enhance the adsorption capacity.

[0045] In an embodiment of the utility model, a first bonding layer is provided between the electrostatic adsorption layer and the base layer, and the thickness of the first bonding layer is 0.5-2 mm; and / or a second bonding layer is provided between the electrostatic adsorption layer and the water-absorbing material layer, and the thickness of the second bonding layer is 0.1-1.0 cm.

[0046] In the embodiment of the utility model, a third adhesive layer is provided between the water-absorbing material layer and the surface layer, and the thickness of the third adhesive layer is 0.1-1.0 cm.

[0047] The setting of the adhesive layer can improve the adhesion firmness between the layers and prevent the layers from being delaminated. The first adhesive layer, the second adhesive layer and the third adhesive layer can be adhesive glue, and the selection of the adhesive glue is not specifically limited in the utility model. When the coating structure of the utility model is used for a wall, the first adhesive layer, the second adhesive layer and the third adhesive layer can also be a putty layer.

[0048] The utility model also provides a wall structure, including a wall and a coating structure of the utility model, wherein the coating structure is arranged on the surface of the wall. The specific arrangement of the coating structure refers to the above embodiments. Since the wall structure of the utility model adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

On the one hand, the water vapor in the air collides with the dust particles to aggregate, and the aggregated particles formed are adsorbed by the water-absorbing material layer, thereby reducing the dust content in the air.
