Production process of EVA (Ethylene Vinyl Acetate) colored solar film

Abstract

The invention belongs to the field of building materials, particularly relates to a production process of an EVA (Ethylene Vinyl Acetate) colored solar film, and provides the following scheme aiming at the problems of low viscosity and low elongation of the existing film. Comprising the following steps that materials including 100 parts of EVA resin, 1-5 parts of a color pigment powder bag, 5-15 parts of a luminescence agent, 60-85 parts of a mixed solution, 60-85 parts of hydrochloric acid and 45-65 parts of macromolecular wax are prepared, and the luminescence agent comprises an anhydride monomer, a pyrazoline derivative, nickel dioxide powder, a coumarin derivative and hyaluronic acid; the EVA resin can be better fused with other materials through modification of the EVA resin, the viscosity of the EVA resin can be ensured not to be interfered by utilizing the treated colored pigment powder bag and the luminous agent, the layering phenomenon is avoided, the luminous agent and the macromolecular wax can also enhance the strength of the film, increase the elongation of the film and reduce the risk of film breakage, and the service life of the film is prolonged. And the product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a production process of EVA color solar film. Background technique [0002] In the field of architectural decoration, laminated glass has been more and more widely used due to its excellent characteristics such as beauty and firmness. The patent application number CN201710857654.X discloses a production process of EVA color solar film. The invention provides A production process of EVA color solar film, by using EVA material instead of traditional PVB material and adopting low-temperature molding process in the production process, the glass film made can be laminated with glass at a lower temperature, which effectively avoids The effect of high temperature lamination on stained glass film was investigated. [0003] However, there are also some problems in the production process of this EVA color solar film. For example, the degree of mutual fusion between the material...

Problems solved by technology

[0003] However, there are also some problems in the production process of this EVA color solar film. For example, the degree of mutual fusion between the materials is low, which leads to a decrease in the viscosity of the film, and cannot effectively connect the glass plates on both sides, which easily leads to delamination of the product. The strength is reduced, the elongation is reduced, and it is easy to break once it is pulled by an external force
