Abstract
The invention discloses a wear-resistant solvent-resistant fluorocarbon coating for a photovoltaic module and an application method thereof, wherein the fluorocarbon coating comprises the following components: the coating comprises non-soluble fluorocarbon resin, hydroxy acrylic resin, an inorganic wear-resistant additive, a curing agent and an organic solvent, wherein the non-soluble fluorocarbon resin is insoluble in the organic solvent, and the hydroxy acrylic resin is soluble in the organic solvent. According to the invention, through formulation and process innovation, the non-soluble fluororesin is taken as a main body, and is mixed and ground with an organic solvent to form a suspension, the particle size is ensured to be small enough, the coating film is formed through high-temperature melting and curing, the solvent resistance of the coating film is better, the coating film is obviously different from a soluble fluororesin reaction film-forming mechanism in the prior art, and the inorganic wear-resistant additive is introduced, so that the wear resistance and the solvent resistance of the fluorocarbon coating film are obviously improved on the basis of meeting the requirements on weather resistance and adhesive force, the application of a back plate, a photovoltaic module and the like under most climatic conditions can be met, the coating film can be used as a transparent front plate material of the photovoltaic module, and the universality is stronger.
Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a wear-resistant solvent-resistant fluorocarbon coating for a photovoltaic module and an application method thereof.
Background
Along with the popularization and the use of the photovoltaic module, the fluorocarbon coating back plate is widely applied to the photovoltaic module due to the advantages of good weather resistance, good bonding force, high cost performance and the like.
The Chinese patent of invention, publication No. CN 109735177A, entitled paint for solar cell back panel, discloses: the coating comprises fluorocarbon resin, acrylic resin, pigment, an auxiliary agent, a solvent and an isocyanate curing agent; 9.2-14.4% of fluorocarbon resin, 3.6-9.2% of acrylic resin, 20.5-25.3% of pigment, 37.6-48.1% of solvent and 0.6-1% of auxiliary agent, wherein the molar ratio of the sum of hydroxyl groups in the fluorocarbon resin and the acrylic resin to isocyanic acid radical in the curing agent is 0.8-1.6, and the sum of the components meets the content requirement of 100%. The above patent is based on the soluble fluorocarbon resin chemical crosslinking film forming mechanism, the acrylic resin contains hydroxyl group, which can react with isocyanate in the curing agent, and the hydroxyl group in the fluorocarbon resin also reacts with the curing agent, under the crosslinking action of the curing agent, the fluorocarbon resin and the acrylic resin form chemical bond force, and the good interlayer force of the coating is ensured.
The Chinese patent of the invention, publication No. CN 109054531A, the patent name is a weather-resistant transparent coating and its application, and discloses: the transparent coating is prepared from fluorocarbon resin, modified resin, a first auxiliary agent, inorganic filler, an organic solvent, a second auxiliary agent, a curing agent, a catalyst and the like according to the mass ratio of 100:0-20:0.1-2:0-20:20-120:0.1-40:10-50: 0.1-2. The fluorocarbon resin used in the above patent is mixed with the rest components in advance to prepare transparent coating, and then the transparent coating is coated on the required film, and finally the photovoltaic back plate is obtained through drying and curing.
It should be noted that both of the above two patents are based on the film forming mechanism of the soluble fluorocarbon resin reaction, but the fluorocarbon coating is easy to cause loose structure of the coating due to solvent volatilization, etc., and pinholes are easily formed on the surface, so the wear resistance and solvent resistance are significantly lower than those of the fluorine film type back plate, and the application of the back plate and the photovoltaic module in harsh climatic regions such as desert, coastal areas, etc. is limited. Therefore, the development of a film-forming coating based on insoluble fluorocarbon resin has important practical significance.
