Description
Technical field
The present invention relates to protective film fields, more specifically, it relates to a kind of PE protective film.
Background technique
PE protective film biggest advantage be protected product in production and processing, transport, storage and use process not by
Pollution, burn into scratch, and original bright and clean glossy surface are protected, to improve the quality and the market competitiveness of product.
But protective film is after being used for a while, centre performance is good, but both ends wing rises, and this phenomenon occurs
Main cause is protective film in paste process, level of stretch is larger with protected profile, after note is good, meets high temperature ring
There is unnecessary rebound phenomenon in border.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of PE protective film, can effectively inhibit
PE protective film generates unnecessary rebound phenomenon in use, meanwhile, adhesive-layer is not easily to fall off, is conducive to PE protective film
Use.
To achieve the above object, the present invention provides the following technical scheme that
A kind of PE protective film including PE base, the binder course being successively set on the inside of PE base and adhesive-layer and is set gradually
Anti-retraction layer and protective layer on the outside of PE base；
The raw material of the PE base includes following parts by weight: 35-65 parts of low density polyethylene (LDPE), 12-35 parts of high density polyethylene (HDPE)；

By taking above-mentioned technical proposal, setting anti-retraction layer can reduce PE protective film in use because need not
The molecular structure of the problem of edge caused by the retraction wanted tilts, thermosetting phenolic resin is tridimensional network, is not easy
Deformation, can effectively inhibit the retraction problems of PE protective film, while add bleeding agent can during preparing PE protective film,
Increase penetration of the thermosetting phenolic resin molecule to protective layer and PE base, and then is resisted back using the increase of intermolecular active force
Bonding strength between contracting layer and protective layer and PE base；Binder course is set between adhesive-layer and PE base simultaneously, with low close
Degree polyethylene makes low density polyethylene (LDPE) combine closely by crosslinked action and adhesive-layer and PE base for matrix by crosslinking agent,
Avoid the problem that adhesive-layer, which occurs, to fall off；Polycarbonate in protective layer increases PE protective film using its good mechanical property
Abrasion-resistant surface performance and tear resistance, while dimethyl siloxane is added as hydrophobing agent, it can occur to avoid polycarbonate
Hydrolysis, and dimethyl siloxane itself has good lubricity, can increase the lubricity of PE protection film surface, avoid PE
Protective film is scratched with other articles in use and is damaged；Simultaneously by low density polyethylene (LDPE) and high density polyethylene (HDPE) shape
At PE base can have both the good plasticity of low density polyethylene (LDPE) and the excellent mechanical performances of high density polyethylene (HDPE)；To make
PE protective film of the invention can have good anti-retraction performance, while having that adhesive-layer is not easily to fall off, not easily damaged is excellent
Point.

The setting of the density of density polyethylene and high density polyethylene (HDPE) can make PE protective film have it is good it is thermoplastic simultaneously, intensity obtains
To further strengthening, PE protective film is avoided to tear in use, while the low density polyethylene (LDPE) in binder course raw material
Density setting, makes the draftability of binder course be better than PE base, and then without limitation on arriving the stretching of PE protective film in use
Deng operation, the normal use of PE protective film is not interfered with.
The further setting of the present invention is that the bleeding agent is fatty alcohol polyoxyethylene ether or alkyl phenol polyoxyethylene ether.
By taking above-mentioned technical proposal, fatty alcohol polyoxyethylene ether alkyl phenol polyoxyethylene ether is non-ionic surface active
Agent had not only had hydrophilic group on molecular structure but also had had lipophilic group, and can penetrate into the raw material of protective layer and PE base well
In molecule.
The further setting of the present invention is that the crosslinking agent is the mixture of cumyl peroxide and zinc oxide, described
The weight ratio of cumyl peroxide and oxidisability is (2-5): (1-3).
By taking above-mentioned technical proposal, cumyl peroxide can promote in PE base and adhesive-layer as crosslinking agent
Unsaturated bond and binder course in unsaturated bond crosslink effect and form chemical bond, and then adhesive-layer and PE can be increased
Bonding strength between base avoids the problem that adhesive-layer, which occurs, to fall off, while adding zinc oxide to increase peroxide diisopropyl
The ageing resistance and mechanical strength of benzene, increase the service life of adhesive-layer.
The further setting of the present invention is that the age resister is the mixture of dibutyl hydroxy toluene and silica,
The weight ratio of the dibutyl hydroxy toluene and silica is (1-5): (1-4).
By taking above-mentioned technical proposal, dibutyl hydroxy toluene can rely on its own automatic oxygen as antioxidant
The property of change effectively inhibits PE protective film that oxidative phenomena occurs, while silica is as shield type anti ultraviolet agent, can be effective
Avoid PE protective film by the damage of ultraviolet light.
