Embodiment 1

[0034] A XB-S-water-soluble high-reflective photovoltaic backplane glass coating is produced by the following steps:

[0035] a) Mixing: first mix and stir the water-soluble acrylic modified resin, diethylene glycol butyl ether and purified water for 10-20 minutes, then add low-temperature glass powder and stir together for 10-20 minutes, then add polyethylene glycol 400 and stir. 10-20 minutes, finally add titanium dioxide and stir for 20-30 minutes;

[0036] b) Grinding: Grind the product of step a) below 70°C, with a fineness of 10-20μm;

[0037] c) Secondary mixing: adding melamine formaldehyde resin and phenethyl alcohol oleate to the product obtained in step b) and stirring for 10-20 minutes to obtain the crude XB-S-water-soluble high-reflective photovoltaic backplane glass coating;

[0038] d) Detection: take part of the crude paint in step c) and dry it at 170-190°C for 10 minutes, and then take part of the crude product and bake it at 680-700°C for 90-110 seconds to test the ...

Embodiment 2

[0052] Same as Example 1, but the difference is:

[0053] The amount of raw materials added in the step a) and step c) is calculated by mass percentage, and the ratio is:

[0055] 0.5% melamine formaldehyde resin,

[0056] Phenyl alcohol oleate 0.5%,

[0057] Polyethylene glycol 400 0.5%,

[0058] Titanium dioxide 33.5%,

[0059] Low temperature glass powder 45%,

[0060] Diethylene glycol butyl ether 5%,

[0061] Clean water 5%.

Embodiment 3

[0063] Same as Example 1, except that:

[0064] The amount of raw materials added in the step a) and step c) is calculated by mass percentage, and the ratio is:

[0065] 15% water-soluble acrylic modified resin,

[0066] 0.5% melamine formaldehyde resin,

[0067] Phenyl alcohol oleate 0.5%,

[0068] Polyethylene glycol 400 0.5%,

[0069] Titanium dioxide 33.5%,

[0070] Low temperature glass powder 40%,

[0071] Diethylene glycol butyl ether 5%,

[0072] Clean water 5%.

Abstract

The invention relates to an XB-S-water-soluble high-reflection photovoltaic backboard glass coating material and an application scheme thereof, wherein the XB-S-water-soluble high-reflection photovoltaic backboard glass coating material is obtained from an acrylic acid modified resin, a leveling agent, an antifoaming agent, a dispersing agent, titanium dioxide, low-temperature glass powder, diethylene glycol butyl ether and purified water through five steps of a) mixing, b) grinding, c) secondary mixing, d) detecting and e) packaging. The application scheme comprises: spray coating, silk-screen printing, roll coating and shower coating. According to the invention, the XB-S-water-soluble high-reflection photovoltaic backboard glass coating material is high in reflectivity, high in adhesionrate, strong in wear resistance and environment-friendly, meets ROSH detection, does not affect the photovoltaic conventional test, can improve the reflection of light by the film layer so as to absorb more light into the battery sheet, and improve the photoelectric conversion power of the assembly; and different application schemes are selected according to requirements, and the application performance of the product is improved.

Description

Technical field [0001] The invention relates to a water-soluble glass paint, in particular to a XB-S-water-soluble high-reflection photovoltaic backplane glass paint and an application scheme thereof. Background technique [0002] The glass coating undergoes a strengthening method of 680-720℃ high temperature instant baking and instant cooling, so that the glass pigment and the glass body are melted into one body, and the adhesion and durability of the color are realized. The glass structure after being colored and strengthened is strong and strong. Atmospheric corrosion has strong resistance, good corrosion resistance and hiding power. [0003] Photovoltaic backplane glass coatings are mainly used for photovoltaic power generation glass to increase light reflection and improve light utilization. At present, the common glass coatings for photovoltaic backplanes cannot have a balance between high performance and environmental protection. Therefore, it is of great significance to i...
