Detailed Description
For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.
The self-cleaning glass heat-insulating coating provided by the embodiment of the invention comprises the following raw materials in percentage by weight: 40-80% of water-based nano heat-insulating dispersion liquid, 18-60% of inorganic film forming material, 0.5-2% of dispersion stabilizer and 0.5-2% of rheological additive.
Further, the aqueous nano heat insulation dispersion liquid is a tin antimony oxide dispersion liquid, an indium tin oxide dispersion liquid or a cesium tungsten bronze dispersion liquid.
Further, the inorganic film forming material is one or more of potassium silicate solution, lithium silicate solution and silica sol mixed at any ratio.
Further, the dispersion stabilizer is a quaternary ammonium salt dispersion stabilizer, a tertiary amine dispersion stabilizer or an organic-inorganic silicide stabilizer.
Further, the rheological aid is hydroxyethyl cellulose ether or an anionic heteropolysaccharide derivative.
A preparation method of a self-cleaning glass heat insulation coating comprises the following specific steps: and (3) placing the aqueous nano heat-insulating dispersion liquid into a container, adding the inorganic film-forming material, the dispersion stabilizer and the rheological aid at a stirring speed of 100-200 r/min, increasing the stirring speed to 300-500 r/min, uniformly stirring, and discharging to obtain the self-cleaning glass heat-insulating coating.
Preparation of TiO in the patent application No. 201710393289.12When ATO composite functional nano powder particles are used, corrosive substances such as concentrated sulfuric acid and hydrogen peroxide are used, so that the problem of high risk is solved; aiming at the problems of poor hardness, scratch resistance, weather resistance and the like of the film forming material which is aqueous polyurethane; one or more of potassium silicate solution, lithium silicate solution and silica sol are selected as film forming substances, so that the coating is high in hardness and good in weather resistance.
Aiming at the patent 'a heat-insulating self-cleaning glass coating' with the application number of 201210229882.X, film-forming substances of the heat-insulating self-cleaning glass coating are organic resin and incomplete environment-friendly materials, and epoxy resin and polyurethane resin are used outdoors and have the problems of poor weather resistance, easy color change, pulverization and the like.
The water-based organic film-forming substance is attached to the surface of the glass through mechanical adhesion and is simply 'adhesion', and the inorganic film-forming substance penetrates deep into the glass substrate and forms a permanent and long-term chemical bonding effect with the glass; and the crystallization property of the inorganic film-forming material determines that the inorganic film-forming material is porous, and the size of the pores can allow water vapor to freely pass through and can prevent liquid rainwater from passing through. By allowing the free passage of water vapor (breathability), blistering and flaking of the coating is almost eliminated. The inorganic film forming material has a Si-O-Si structure, large bond energy (460KJ/mol) and excellent weather resistance. As shown in FIG. 1, the inorganic film-forming material has a film-forming mechanism different from that of the common organic film-forming material, and is a reactive film-forming material, so that the paint film has high hardness and strong adhesion.
The surface of the inorganic film forming material has no residual electrostatic charge, so that dust is not easy to adsorb; meanwhile, the inorganic binder has no thermoplasticity, and the surface of the inorganic binder is not polluted and dirtied by dirt even at high temperature in summer. The organic film-forming material generates static electricity due to friction in wind, and dust particles in the air are attracted to the surface of the coating. Organic film formers exhibit thermoplastic properties and at higher temperatures the surface becomes "tacky" thereby creating ideal conditions for soil particles to stick and agglomerate extensively on the surface. The super-hydrophilic inorganic coating has uniform and consistent surface, can form a water film in a rainwater environment and take away dust and impurities adhered to the surface, is cleaner and has a self-cleaning effect. Inorganic silicate coatings are also resistant to mold and fungus growth because of their high pH and lack of any organic components as nutrients for spore growth, which keeps the surface clean. The silicate structure is highly stable, can resist acid and alkali erosion, and the inorganic coating film is very easy to clean.
Example 1:
50 percent of tin antimony oxide dispersion liquid (the solid content is 30 percent) is weighed and placed in a container, 25 percent of potassium silicate solution with the modulus of 3.5, 12.5 percent of potassium silicate solution with the modulus of 3.9, 7.5 percent of lithium silicate solution with the modulus of 4.8, 2.5 percent of quaternary ammonium salt dispersion stabilizer and 2.5 percent of hydroxyethyl cellulose ether (the solid content is 2 percent) are added in the stirring process at the speed of 200r/min, the stirring speed is increased to 300r/min, the mixture is discharged after being uniformly stirred, and the self-cleaning glass heat-insulating coating is prepared.
Example 2:
weighing 50% of cesium tungsten bronze dispersion (with the solid content of 30%) and placing the dispersion in a container, adding 25% of potassium silicate solution with the modulus of 3.5, 12.5% of potassium silicate solution with the modulus of 3.9, 7.5% of lithium silicate solution with the modulus of 4.8, 2.5% of quaternary ammonium salt dispersion stabilizer and 2.5% of hydroxyethyl cellulose ether (with the solid content of 2%) while stirring at 200r/min, increasing the stirring speed to 300r/min, uniformly stirring, discharging, and preparing the self-cleaning glass heat-insulating coating.
Comparative example 1:
weighing 50% of tin antimony oxide dispersion liquid (the solid content is 30%) and placing the tin antimony oxide dispersion liquid into a container, adding 45% of aqueous polyurethane emulsion, 2.5% of rheological additive and 2.5% of hydroxyethyl cellulose ether (the solid content is 2%) while stirring at 200r/min, raising the stirring speed to 300r/min, uniformly stirring, discharging, and preparing the self-cleaning glass heat-insulating coating.
The following table shows the data comparison between the examples and the comparative examples
From the above table it can be seen that: the comparative example 1 is a conventional waterborne polyurethane emulsion system, the paint film hardness and the adhesive force performance of the conventional waterborne polyurethane emulsion system are both low, and the paint film slightly changes color after ultraviolet aging, the performance parameters highlight the problems that the organic emulsion system is easy to color and fall off and the weather resistance is poor when being used outdoors, the scheme takes an inorganic material as a film forming material, and the prepared self-cleaning glass heat-insulating film has ultrahigh hardness, excellent adhesive force and ultrahigh weather resistance; solves the problem of poor weather resistance of the organic coating.
The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the present invention.
