Abstract
The invention discloses a water-based resin strippable transparent heat-insulating coating capable of being filled in an aerosol can, which is prepared from the following raw materials in percentage by mass: 40-60% of water-based resin, 10-30% of nano metal oxide, 5-25% of solvent and 5-15% of auxiliary agent; the waterborne resin is one or more of waterborne modified acrylate resin and waterborne modified polyurethane dispersoid; the nano metal oxide is at least one of indium tin oxide, antimony tin oxide and modified antimony tin oxide. The water-based resin strippable transparent heat-insulating coating can be filled in an aerosol can, is convenient to spray, use and operate, simultaneously has heat-insulating property and daylighting property, and is green and environment-friendly; and can be easily peeled from the glass when not needed.
Description
Technical Field
The invention belongs to the technical field of water-based transparent heat-insulating coatings, and particularly relates to a water-based resin strippable transparent heat-insulating coating capable of being filled in an aerosol can.
Background
With the continuous improvement of the requirements of people on working and living environments, the transparent heat-insulating coating is used as a new coating variety, and provides a new choice for people. For example, in the fields of building glass curtain walls, household glass doors and windows, lighting strips of factory warehouses and the like, the transparent heat-insulating coating has irreplaceable effects, not only meets the heat-insulating requirement, but also keeps certain lighting effect.
At present, technical researches on transparent heat-insulating coatings mainly aim at solving the problems of high light transmittance, high infrared shielding effect, high hardness, high adhesive force, no VOC (volatile organic compounds) emission and the like. The transparent heat-insulating coating mainly comprises a functional filler transparent conductive oxide and a film-forming filler, wherein the functional filler transparent conductive oxide is uniformly dispersed in a dispersion medium through a physical or chemical method to form a stable and uniform dispersion liquid, then the stable and uniform dispersion liquid is mixed with a certain proportion of high polymer resin, a certain amount of coating film-forming additives such as a dispersing agent, a leveling agent, a defoaming agent, a thickening agent and the like are added into the dispersion liquid, and the mixture is uniformly stirred to obtain a final product. The transparent heat-insulating coating can be coated on cleaned glass by spraying, brushing, curtain coating and other methods, and a coating film capable of realizing heat-insulating and heat-preserving effects is formed on the surface of the glass in a natural air drying, heat curing, ultraviolet aging and other modes.
And for the construction simplicity of the transparent heat-insulating coating, the personalized requirements of people and other aspects, corresponding technologies are lacked. The prior art discloses transparent heat-insulating coatings, which require professional constructors and construction equipment. For example, document CN114933328a discloses a fluorine-tungsten co-doped nano titanium dioxide transparent heat-insulating material, which is prepared by mixing octadecanol or hexadecanol as a solvent, octadecene or n-tetradecene as a surfactant, oleic acid and oleylamine as morphology control agents in a titanium source, a fluorine source and a tungsten source substrate, uniformly stirring and heating in a nitrogen atmosphere until solid particles in the raw materials are dissolved, degassing, heating to 300-330 ℃, keeping the temperature for 1-2 hours, cooling, washing, drying and grinding. The construction operation has high technical requirements on constructors, and once the operation is improper, the transparent heat-insulating coating cannot exert the corresponding performance, but the appearance and the lighting effect are influenced. Meanwhile, once the transparent thermal insulation coating is applied to the surface of an object, the thermal insulation coating is very cumbersome and difficult to remove.
Document CN114854305a discloses an ion-doped titanium dioxide/copper sulfide composite transparent heat-insulating coating, which is obtained by adding ion-doped titanium dioxide and metal ion-doped copper sulfide nanosheets into an organic solvent, adding a film-forming resin, uniformly mixing under high-speed stirring, adding a dispersing agent, and uniformly stirring; the organic solvent is dimethyl sulfoxide, toluene or butyl acetate; the film-forming resin is polydimethylsiloxane, ethyl cellulose and epoxy resin. However, the document adopts toxic dimethyl sulfoxide and toluene as organic solvents, which are not only harmful to the health of constructors and residents, but also high in the emission of VOCs to the environment.
