Abstract

The invention relates to the field of solar cleaning supplies, particularly to a photovoltaic cell panel cleaning agent with good anti-freezing performance, and a preparation method thereof, wherein the cleaning agent comprises: polyoxyethylene fatty alcohol ether, dihexyl sodium sulfosuccinate, coconut acid diethanolamide, sodium pyrophosphate, a buffer solution, isopropanol and distilled water.According to the invention, the prepared cleaning agent has excellent anti-freezing performance; the pH value of the component B is kept at 7-8 by utilizing the buffer solution in the preparation process of the cleaning agent, so that the component B is weakly alkaline so as to effectively enhance the cleaning effect; sodium hydroxide and epoxypropane are introduced into the fatty alcohol polyoxyethylene ether, and the polyether molecular structure can reduce the viscosity to improve the fluidity, so that the modified fatty alcohol polyoxyethylene ether has low foaming property so as to improve the washing property; and the compatibility of the modified fatty alcohol polyoxyethylene ether, the dihexyl sodium sulfosuccinate, the coconut acid diethanolamide and the sodium pyrophosphate is good, so that the photovoltaic cell panel can be efficiently cleaned through the mutual synergistic effect of the four components.

Description

technical field [0001] The invention relates to the field of solar cleaning products, in particular to a cleaning agent for photovoltaic panels with good antifreeze performance and a preparation method thereof. Background technique [0002] With the deterioration of the environment and the deepening of human environmental awareness, photovoltaic power generation, as one of the main green energy sources, has been applied more and more. The number and scale of photovoltaic power plants are also increasing. Once a photovoltaic power station is built, its power generation is basically dependent on the sky. In addition to avoiding the loss of electrical equipment due to failure, the main way that manpower can control is to clean the surface of the components. This is where there is pollution and dust. place is particularly obvious. The impact of dust accumulation on solar photovoltaic power plants: Dust, as a substance with a small thermal conductivity, is attached to the surfa...
