Description
Technical Field
The invention relates to the technical field of paint, in particular to a photovoltaic glass plate paint with high water resistance and high light transmittance and a preparation method thereof.
Background
The photovoltaic glass is used as an external component of the photovoltaic module, so that the conversion rate of the photovoltaic module is influenced, and the photovoltaic module is protected from external factors. The existing photovoltaic glass plate is ultrathin, surface coated and low-iron (ultra-white) glass and the like. The most widely used solar photovoltaic glass today is high transmittance glass, which is a low iron content glass, known in the industry as ultra-white glass. In order to improve the service life, the protection effect and the aesthetic effect of the photovoltaic glass, the application of the photovoltaic glass plate coating is wider and wider, so that the life cycle of the photovoltaic glass plate is longer, the power attenuation rate is low, the water vapor transmittance is close to zero, the wear resistance is good, and the PID attenuation is small.
Typical photovoltaic glazing panel coatings are exposed to open air conditions and are susceptible to high temperatures and rain, resulting in flaking and thus affecting the useful life of the photovoltaic glazing panel.
The prior patent CN201310495873.X discloses a preparation method of high-hardness water-based glass baking varnish, the prepared high-hardness water-based glass baking varnish film has high hardness, scratch resistance and good wear resistance, but is mainly used for protecting and decorating the surfaces of products such as wine bottles, perfume bottles and the like, the glass products are polished first in the application process, then the baking varnish is carried out, the process is complex, and the light transmittance and the water resistance of the glass products are to be enhanced.
Disclosure of Invention
The invention provides a high-water-resistance high-light-transmittance photovoltaic glass plate coating, which is prepared from 40 to 50 parts of organic resin, 0.2 to 0.4 part of nano color pigment, 0.2 to 0.4 part of high-light-transmittance pearlescent pigment, 5 to 10 parts of cosolvent, 1.5 to 3 parts of thickener, 0.5 to 1 part of coupling agent, 0.5 to 1 part of dispersing agent, 5 to 10 parts of filler, 0.3 to 0.5 part of defoamer, 0.2 to 0.5 part of flatting agent and 45 to 50 parts of deionized water according to parts by weight.
Preferably, the organic resin comprises one or more of acrylic dispersion, silicone resin, aqueous amino resin, aqueous urethane acrylic resin and epoxy resin.
Preferably, the acrylic dispersion includes a fluorine-containing acrylic dispersion and a hydroxyl-containing acrylic dispersion.
Preferably, the acrylic dispersion comprises one or more of Hua Tongrui to 537, basf S938AP, scion chemical BV9300; further preferred is the scion chemical BV9300.
Preferably, the scion chemical BV9300 is a hydroxyl acrylate secondary fraction containing hydroxyl functional groups.
Preferably, the pH value of the amentoflavone chemical BV9300 is 6-8, the ion type is anions, the solid content is 45+/-2%, the viscosity is 1000-3000cps/25 ℃, the formaldehyde/APEO is Free, and the solid content of hydroxyl is 3.3%.
According to the invention, by adding the acrylic acid dispersion of the BV9300 in the Tay chemical industry, the light transmittance of the photovoltaic glass plate coating is improved, and meanwhile, the water resistance and the ageing resistance of the photovoltaic glass plate coating are improved. The inventors found that the water resistance was greatly improved by adding a hydroxyl group-containing acrylic resin during the experiment. However, acrylic resins of different brands affect their light transmittance and thus the light conversion efficiency of their photovoltaic modules. Through continuous experiments, the inventor finally discovers that the water resistance and ageing resistance of the photovoltaic glass plate coating are maintained while the light transmittance of the photovoltaic glass plate coating is improved by adding the acrylic acid dispersion of the chemical BV9300. The inventors speculate that the hydroxyl group is contained in the acrylic resin, which can improve the water resistance, but the more the hydroxyl group belongs to the energy absorbing group, the greater the absorption of visible light and near infrared light, the lower the light transmittance, thereby influencing the working efficiency of the photovoltaic module. The specific acrylic acid dispersoid in the ear-to-ear chemical BV9300 influences the performance of the photovoltaic glass plate coating by the specific structure and the unique physical parameters, so that the light transmittance of the photovoltaic glass plate coating can be improved, and the water resistance and the ageing resistance of the photovoltaic glass plate coating can be improved.
Preferably, the nano-color pigment comprises nano-high-permeability paste.
Preferably, the color of the nano-colored pigment comprises one or more of white, yellow, violet, blue or red.
Preferably, the nano color pigment is TSI series of guangdong new materials science and technology limited company.
Preferably, the color of the high-transmission pearlescent pigment comprises one or more of white, yellow, violet, blue, or red.
Preferably, the high-permeability pearlescent pigment is pearl chemical high-permeability pearlescent powder.
According to the invention, the high-transmittance nano color paste and the high-transmittance pearlescent pigment are added to be compounded with each other, so that the light transmittance of the coating film is improved, and the power generation efficiency of the photovoltaic module and the decoration effect of the photovoltaic glass are improved. The invention adopts the high-transmittance nano-level color paste and the pearlescent pigment, and compared with the common color paste and the pearlescent pigment, the light transmittance of the invention is greatly improved.
Preferably, the cosolvent is two of dipropylene glycol methyl ether, diethylene glycol methyl ether, propylene glycol butyl ether, ethylene glycol, dipropylene glycol methyl ether acetate, ethylene glycol butyl ether acetate, ethylene glycol ethyl ether and ethylene glycol butyl ether.

Preferably, the coupling agent comprises one or more of Nanjing Orcheng chemical AC-313, jin Runna KRN8028B and Nanjing holohedral chemical QX-6045.
According to the invention, the KRN8028B coupling agent is added, so that the weather resistance and the service life of the coating are improved, and the adhesive force of the coating is also improved. The inventor finds that after the acrylic acid dispersion of the amentoflash chemical BV9300 and the filler are added, the light transmittance and the water resistance of the amentoflash chemical BV9300 are greatly increased, but the adhesive force, the weather resistance and the service life of the amentoflash chemical BV9300 are not improved, the inventor finds that the coupling agent with the model of KRN8028B is selected in a long-term test, the PCT test time is longest, the time reaches 48 hours, the adhesive force can reach the first level, and the amentoflash chemical BV can withstand long-term exposure and rain drop. The inventors speculate that the siloxy groups of the KRN8028B coupling agent are reactive with the filler and that the organic functional groups are reactive and compatible with the scion chemical BV9300 acrylic dispersion. Therefore, when the silane coupling agent is between the inorganic and organic interfaces, a bonding layer of the organic matrix-the silane coupling agent-the inorganic matrix can be formed, thereby improving the weather resistance and the service life of the coating and improving the adhesive force of the coating.
Preferably, the filler is porous silica microspheres.
Preferably, the porous silica microspheres are purchased from beijing, the company of the sciences, kokumi.
Preferably, the dispersant is alkylaryl phosphate and sodium polymethacrylate.
Preferably, the weight ratio of the alkylaryl phosphate to the sodium polymethacrylate is (2-4): 1, a step of; further preferably, it is 3:1.
preferably, the alkylaryl phosphate is ZETASPERSE 3800.
In the invention, the weight ratio of alkylaryl phosphate to sodium polymethacrylate is controlled to be 3:1, the viscosity stability and the light transmittance of the paint are improved. The inventors found that the weight ratio of alkylaryl phosphate to sodium polymethacrylate in the dispersant is different, and in the system, the dispersion performance can be improved, the initial viscosity of the paint can be reduced, the initial viscosity can reach 305 mPa.S at 25 ℃, and the viscosity change is small under the heat storage of 50 ℃ for 28 days. The inventor finds in experiments that when only sodium polymethacrylate is used, the dispersion performance is poor, the light transmittance is also reduced to a certain extent, and the inventor speculates that controlling the weight ratio of alkylaryl phosphate to sodium polymethacrylate can possibly improve the energy barrier between porous silica microspheres, thereby increasing the repulsive force between particles, fully dispersing the porous silica microspheres and pigment, and greatly reducing the density and light refractive index of silica; meanwhile, the specific surface area of the hollow structure of the silica microsphere is large, and sunlight can be continuously reflected inside the hollow structure, so that the light utilization rate is high, and the light transmittance of the coating is improved.
