Scaling powder for solar photovoltaic components and preparation method of scaling powder

Abstract

The invention discloses scaling powder for solar photovoltaic components and a preparation method of the scaling powder. The scaling powder comprises 3-9 parts of dicarboxylic acid, 1-2.5 parts of hexadecylsulfonic acid sodium salt, 0.5-1.5 parts of fatty amine polyoxyethylene ether, 1.5-3.5 parts of cetyl dimethyl amine oxide, 0.5-2.5 parts of octadecyl dimethyl benzyl ammonium chloride, 1.0-4 parts of linolenic acid, 0.1-2 parts of an active additive, 5-15 parts of polyethylene glycol and 80-110 parts of absolute ethyl alcohol. The ingredients are uniformly mixed to prepare the scaling powder. The scaling powder is especially suitable for the solar photovoltaic components, and residues are less. The influence of the residues of the scaling powder at the present stage on the solar energy industry is solved.

Description

【Technical field】 [0001] The invention belongs to the field of solar photovoltaic, and relates to a flux for solar photovoltaic components and a preparation method thereof. 【Background technique】 [0002] In the face of resource depletion, human beings have realized its seriousness. Many countries have begun to try to solve the energy crisis by saving energy and protecting the environment, but they cannot change the limited reserves of existing mineral resources and the pollution to the environment after use. Two indisputable facts, but can only alleviate the crisis to a certain extent. The fundamental way and the ultimate way to solve the energy crisis is to find a renewable clean new energy. Thus, the solar photovoltaic industry was born. With the continuous rise of crude oil prices and the attention of environmental and climate issues, governments of various countries, especially developed countries, have paid more and more attention to the development of the solar en...

Problems solved by technology

[0003] With the solar photovoltaic industry gradually turning to integration and multi-functional development, the requirements for flux performance are getting higher and higher, and the existing flux residues are harmful to The impact of photovoltaic modules has the following points: too much flux residue will corrode the battery sheet; too much solid residue will reduce electrical conductivity, cause migration or short circuit; too much residue will bond dust and debris; affect product reliability ; Affect the bonding between EVA and the cell; may generate continuous air bubbles on the busbar of the cell

The existence of the above problems affects the use of flux, so it is necessary to improve the formula and process of flux
