Background
The cross flow fan is one of the important air conditioner functions, and the fan blade which is the mainstream at present is a resin base material, wherein AS resin is mainly used. However, the AS resin material has a surface that is prone to dust adhesion due to factors such AS high surface energy and strong surface polar groups; meanwhile, as the fan resin base material has insulativity, the fan resin base material is rubbed with air in the operation process to cause electrostatic accumulation so as to adsorb dust in the air, and the humidity of the internal environment of the air conditioner is higher, so that the adhesion and accumulation of the dust are aggravated. According to investigation and measurement, 20% -30% of dust in the air conditioner is accumulated on the surface of the fan at present, the dust is one of the most serious parts in the air conditioner, and further bacteria can be bred to pollute indoor air.

The surface of the fan blade has higher antistatic performance, low dust amount adsorbed and accumulated in long-term operation and long service life.
However, although the fan blade has high antistatic performance, the antistatic and dustproof performance of the fan blade is not durable due to small interaction among the components.

Detailed Description
The technical solutions in the embodiments of the present invention will be fully described in detail below. It is obvious that the described embodiments are only some specific embodiments, not all embodiments, of the general technical solution of the present invention. All other embodiments, which can be derived by a person skilled in the art from the general idea of the invention, fall within the scope of protection of the invention.
The invention provides a cross-flow fan, wherein the surface of the cross-flow fan is provided with a composite coating, the composite coating comprises a primer layer and a finish paint layer, the primer layer comprises 10-25 mass% of film-forming resin, 0.5-5 mass% of first coupling agent, 0.01-3 mass% of surfactant and 70-89 mass% of water; the finishing paint layer comprises 5-20 mass% of film-forming resin, 0.5-5 mass% of graphite, 0.2-3 mass% of inorganic nanoparticles, 0.5-5 mass% of second coupling agent, 0.01-3 mass% of surfactant, 0-1 mass% of auxiliary agent and 70-93 mass% of water. The cross-flow fan has the characteristics of strong and durable anti-static capability, good antifouling performance to diversified dirt, capability of inhibiting growth of water drops and excellent durability. The raw materials of the composite coating do not use the traditional organic solvent, but the surfactant is added into the water to fully activate the molecules of the film-forming resin in the water, so that the film-forming resin is dispersed in the water, the use of the organic solvent is greatly reduced, and the use of the surfactant reduces the use of the organic solvent, so that the composite coating is more environment-friendly.
Further, the addition amount of the film-forming resin in the primer layer is limited to 10-25% of the total mass of the primer layer liquid, because the curing time of the coating is prolonged due to the excessively high content of the film-forming resin, the production efficiency is reduced, and the cost is increased; the film forming effect of the coating is not good easily caused by the low content of the film forming resin; the addition amount of the first coupling agent is limited to 0.5-5 mass percent, because the first coupling agent cannot play a role in crosslinking when the content of the first coupling agent is too low, so that the film forming property of the coating is poor, and the crosslinking degree of the coating is increased easily when the content of the first coupling agent is too high, the coating is hardened and the toughness of the coating is poor; the wear resistance of the composite coating can be further improved by adding the inorganic nano particles into the finish paint layer,the roughness of the composite coating is reduced, the addition amount of the inorganic nano particles is limited to be 0.5-5% of the total mass of the finishing paint liquid by the technical scheme, and the reason is that the formation of the coating is difficult to control due to the excessively high addition amount of the inorganic nano particles, the cost is greatly increased, and the wear resistance of the coating is poor due to the excessively low content of the inorganic nano particles; the graphite structure is relatively stable, cracking and breaking are not easy to occur, the effect is durable, the graphite is not easy to break to provide a carbon source for growth and attachment of microorganisms for small molecules, and meanwhile, the graphite and inorganic nanoparticles such as nano titanium dioxide and the like are jointly used as raw materials of a finish paint layer, so that on one hand, the nano zinc oxide and the nano titanium dioxide can play a role of an opacifier, and the long-term irradiation of ultraviolet light is prevented from causing the service life attenuation of the graphite; on the other hand, graphite can be mixed with part of inorganic nanoparticles (TiO)2、CuO、Cu2O、Fe3O4) The complex formulation can shorten the forbidden bandwidth of inorganic nano particles, or can excite electron-hole pairs to separate and decompose dust when potential energy such as temperature changes, and further improve the dustproof effect, so that the surface of the cross flow fan can have permanent antistatic performance by adding graphite into the finish paint layer, and the technical scheme also limits the addition amount of the graphite to be 0.5-5% of the total mass of the finish paint liquid, because the composite coating has stronger antistatic performance in the range; the addition amount of the second coupling agent is limited to 0.5-5 mass%, because the second coupling agent cannot play a role in crosslinking when the content of the second coupling agent is too low, so that the film forming property of the coating is poor, and the crosslinking degree of the coating is increased easily when the content of the second coupling agent is too high, the coating becomes hard, and the toughness of the coating is poor. Further, the embodiment also limits the addition of the film-forming resin in the finish paint layer, because the film-forming resin can enhance the bonding effect of the finish paint material, improve the material strength, improve the surface hardness and improve the corrosion resistance of the finish paint.
In a preferred embodiment, the film-forming resin is at least one selected from the group consisting of acrylic resin, polyurethane resin, alkyd resin, fluororesin, and epoxy resin. The technical scheme particularly limits the types of the film-forming resins, and the reason is that at least one of the film-forming resins can effectively improve the film-forming property of the primer layer, so that the performance of the composite coating is improved. It will be appreciated that the film-forming resin may also be other materials reasonably selected by one skilled in the art in combination with common general knowledge in the art.
In a preferred embodiment, the surfactant is selected from an anionic surfactant or a polymeric surfactant; the anionic surfactant is selected from at least one of sodium dodecyl benzene sulfonate, stearic acid and sodium dodecyl sulfate; the high molecular type surfactant is at least one selected from sodium polymethacrylate, polyacrylamide, polyvinylpyrrolidone, polyoxyethylene stearate, acrylamide copolymer, polyethylene benzyl trimethyl ammonium salt and sodium carboxymethyl cellulose. The technical solution defines the kind of surfactant in particular, it being understood that the surfactant may also be other substances reasonably selected by the person skilled in the art in combination with the common general knowledge in the art.
In a preferred embodiment, the first coupling agent and the second coupling agent are each independently selected from at least one of a silane coupling agent, a bimetallic coupling agent, a titanate coupling agent, and an aluminate coupling agent, optionally, the first coupling agent and the second coupling agent are each independently selected from at least one of n-octyltrimethoxysilane, dodecyltrimethoxysilane, octadecyltrimethoxysilane, octadecyltrichlorosilane, tridecafluoroctyltrimethoxysilane, tridecafluoroctyltriethoxysilane, perfluorodecyltriethoxysilane, perfluorodecyltrichlorosilane, methoxytrimethylsilane, hexamethyldisilazane, 2-bis (allyloxymethyl) -1-butoxytris (dioctylphosphonoxy) titanate, distearoyloxyisopropoxy aluminate, and (acetoacetic acid ethyl) diisopropoxyaluminate. The present solution defines in particular the type of first and second coupling agents, it being understood that the first and second coupling agents may also be other substances reasonably chosen by the person skilled in the art in combination with the common general knowledge in the field.
In a preferred embodiment, the inorganic nanoparticles are selected from at least one of nano-silica, nano-alumina, nano-magnesia, nano-titania and nano-copper oxide; the average particle diameter of the inorganic nanoparticles is 10-100 nm. The technical scheme further defines the types and average particle sizes of the inorganic nanoparticles, which is beneficial to further improving the wear resistance of the composite coating and obviously reducing the roughness of the composite coating, and it can be understood that the inorganic nanoparticles can also be other substances reasonably selected by the skilled person in combination with the common general knowledge in the art, and the average particle size can also be any point value within the ranges of 20nm, 30nm, 40nm, 50nm, 60nm, 70nm, 80nm and 90 nm.
In a preferred embodiment, the auxiliary agent comprises a leveling agent. The technical scheme specifically limits the types of the auxiliary agents, and it is understood that the auxiliary agents can also be other substances reasonably selected by the person skilled in the art in combination with the common knowledge in the field. It should be noted that the addition of the additive is beneficial to improving the performance of the composite coating, the cost is obviously increased due to the excessively high content of the additive, and the performance cannot be obviously improved continuously; if the content of the inorganic acid is too low, the performance of the composite coating is not obviously improved.
In a preferred embodiment, the primer layer has a thickness of 1-10 μm and the topcoat layer has a thickness of 1-5 μm. The technical scheme limits the thicknesses of the primer layer and the finish paint layer, and has the advantages that the cost is obviously increased due to overhigh thicknesses of the primer layer and the finish paint layer, the performance is not greatly increased, and the stability is reduced; the problem of poor wear resistance of the composite coating is easily caused when the thicknesses of the primer layer and the finishing paint layer are too low.
In a preferred embodiment, the cross-flow fan is obtained by:
adding 10-25 mass% of film-forming resin, 0.5-5 mass% of first coupling agent and 0.01-3 mass% of surfactant into 70-89 mass% of water, and uniformly mixing to obtain primer solution;
uniformly mixing 5-20 mass% of film-forming resin, 0.5-5 mass% of graphite, 0.2-3 mass% of inorganic nanoparticles, 0.5-5 mass% of second coupling agent, 0.01-3 mass% of surfactant, 0-1 mass% of auxiliary agent and 70-93 mass% of water to form a finish paint liquid;
spraying the primer liquid on the surface of the cross-flow fan substrate to form a primer layer;
and spraying the finish paint liquid on the surface of the primer layer to form a finish paint layer, and obtaining the cross-flow fan.
The invention also provides an air conditioner regulator which comprises the cross flow fan in any technical scheme. The air conditioner regulator has better dustproof performance, improves the quality of the air conditioner, and ensures the health of human bodies.
