Problems solved by technology

[0002] Ordinary photovoltaic glass has almost no surface treatment, because most of the spectral reflectance of the treated photovoltaic glass will be changed or weakened to varying degrees, which will affect the photovoltaic conversion efficiency, and the photovoltaic glass will be exposed to the external environment for a long time, and it will be dusty after a period of use , also reduces the photovoltaic conversion efficiency. At this time, manual scrubbing is required, which is time-consuming and laborious. In large-scale photovoltaic projects, the efficiency of manual cleaning is too low

Abstract

The invention relates to the technical field of coatings, and concretely relates to a photovoltaic glass panel surface layer anti-damping coating and a preparation method thereof. The photovoltaic glass panel surface anti-damping coating comprises, by weight, 8-20% of fluorosilicone copolymer resin, 5-12% of silica, 2-8% of a dispersant, 1-5% of a penetrant, 0.5-2% of an antifoaming agent, 1.5-5% of a leveling agent, and the balance of a diluent. The photovoltaic glass panel surface anti-damping coating has a water repellency reaching 95%, has a great water contact angle reaching 130 DEG or more and has a rolling angle being less than 20 DEG, so the coating has a good self-cleaning ability and a light transmittance of 98% or more under rain erosion, and also can guarantee the photovoltaic conversion rate on the premise of a self-cleaning effect. The preparation method of the photovoltaic glass panel surface anti-damping coating has the advantages of simplicity, low cost and high efficiency.

Description

Technical field [0001] The invention relates to the technical field of paint, in particular to an anti-attenuation paint for the surface layer of a photovoltaic glass panel and a preparation method thereof. Background technique [0002] Ordinary photovoltaic glass has hardly undergone surface treatment, because most of the spectral reflectance of the processed photovoltaic glass will change or weaken to varying degrees, which affects the photovoltaic conversion efficiency. The photovoltaic glass is exposed to the external environment for a long time and will be dusty after a period of use. , It also reduces the photovoltaic conversion efficiency. At this time, manual scrubbing is required, which is time-consuming and laborious. In large-scale photovoltaic projects, manual cleaning is too inefficient. Summary of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide an anti-attenuation coati...
