Description
Technical field
The present invention relates to a kind of environment-friendlythin thin film, more particularly to a kind of eva film.
Background technology
Eva film is a kind of environment-friendlythin thin film, is to extrude produced film by being cast by EVA raw materials.Its is degradable.Nothing
Poison is tasteless, and is free of heavy metal.High transparency, softness and tough and tensile.With it is superpower low temperature resistant the characteristics of.
However, the degradation time length of traditional eva film, and finished product has toughness, and feel is poor, and inside is deposited
Particulate matter it is more, cause the finish of film poor.
The content of the invention
In view of the deficienciess of the prior art, the invention provides a kind of good hand touch, reduction speed is fast, degraded cost is cheap
Eva film.
To achieve the above object, the invention provides following technical scheme：A kind of eva film, it is characterised in that it is processed
Recipe ingredient is configured to by mass fraction：50 parts -70 parts of ethylene-vinyl acetate base co-polymer；Antioxidant 10 parts -18
Part；20 parts -25 parts of ultraviolet absorber；15 parts -25 parts of degradation agent；5 parts -8 parts of dispersant；The double stearoylketene amine of N, N ethenylidene
3 parts -5 parts；2 parts -4 parts of dihydric alcohol.
Wherein, antioxidant 2,2- methylene-bis-（4- ethyl -6-6 tert-butyl phenols）.
Wherein, ultraviolet absorber 3,5- di-tert-butyl-4-hydroxybenzoic acid cetyl esters.
Using above-mentioned technical proposal, N, the addition of the double stearoylketene amine of N ethenylidenes can eliminate film endoparticle, avoid finished product
Jaundice, while feel is without toughness, it is smooth, promote the finish of finished films to be improved, the characteristic with high transparency.Antioxygen
Agent is 2,2- methylene-bis- from antioxidant（4- ethyl -6-6 tert-butyl phenols）On the one hand it is due to that its is cheap,
Good in oxidation resistance simultaneously, further can prevent finished films to turn to be yellow；Ultraviolet absorber has anti-ultraviolet effect, to prevent
Its aging provides guarantee.
It is further arranged to：Degradation agent includes low density polyethylene (LDPE) or ultra-low density polyethylene, Et-MAH-EA ternarys are total to
Polymers and dispersant.
Wherein, dispersant is TAS-2A lubrication dispersing agents.
Using above-mentioned technical proposal, each component has preferable compatibility in depressant, after it is added in film proportioning,
Preferable compatibility is likewise supplied with, and degradation speed is fast, and degradation effect is obvious.
