Embodiment Construction

[0011] The present invention provides a high-light-transmitting EVA film whose processing formula components are composed of parts by mass: ethylene-vinyl acetate-based copolymer 50 parts to 70 parts; antioxidants 10 parts to 18 parts; binary 2 parts to 4 parts of alcohol; 1 part to 3 parts of brightener; 20 parts to 25 parts of ultraviolet absorber; 3 parts to 6 parts of compatibilizer. The brightener is erucamide. The ultraviolet absorber is cetyl 3,5-di-tert-butyl-4-hydroxybenzoate. The antioxidant is 2,2-methylene-bis(4-ethyl-6-6 tert-butylphenol). The antioxidant is 2,2-methylene-bis(4-ethyl-6-6 tert-butylphenol). The compatibilizer is ethylene-methacrylic acid copolymer. In the above technical scheme, the addition of N,N vinylidene bis-stearamide can eliminate particles in the film, avoid local aging, and promote the transparency of the finished film to be improved, and it has the characteristics of high transparency. Antioxidant is selected as 2,2-methylene-bis(4-eth...

Abstract

The invention relates to a thin film and especially relates to a high-light-transmittance EVA thin film which is prepared from, by mass, 50-70 parts of ethylene-vinyl acetate based copolymer, 10-18 parts of an antioxidant, 2-4 parts of dihydric alcohol, 1-3 parts of a brightening agent, 20-25 parts of an ultraviolet absorbent, and 3-6 parts of a compatibilizer. By means of the technical scheme, the EVA thin film has high light transmittance, is free of particles, can prevent yellowing and has anti-aging effect.

Description

Technical field [0001] The invention relates to a film, in particular to a high-transmittance EVA film. Background technique [0002] EVA film is a kind of environmentally friendly film, which is produced by casting and extruding EVA raw materials. It is degradable. It is non-toxic, tasteless, and does not contain heavy metals. [0003] However, after the traditional EVA film is processed and formed, there are more granular objects on it, which not only causes the EVA film to be insufficiently transparent, but also easy to age. Summary of the invention [0004] In view of the shortcomings of the prior art, the present invention provides a high light transmittance EVA film with high light transmittance, no particles, anti-yellowing and anti-aging. [0005] In order to achieve the above objective, the present invention provides the following technical solutions: a high-light-transmitting EVA film, which is characterized in that its processing formula components are composed by mass p...
