Description
Technical field
The present invention relates to thin film technique field, specifically, more particularly to high intensity cleaning PE films and preparation method thereof.
Background technology
In recent years, a kind of new model of the container by the use of packaging film as plastic flexible package oneself through being used widely, packaging
Case transport packaging film, common packaging film content have:Oily substance, plasticizer, pitch and fruit juice etc..In the market liquid
Flexible packaging made from plastic film is mainly polyethylene (PE) co-extrusion film, but due to polyethylene（PE）The puncture resistant power of co-extrusion film is poor, holds
Cracky, causes leakage occurs using process and fruit juice aoxidizes, cause direct economic loss and some indirect economic loss,
Loss of material so is caused, while pollution can be also brought to environment, very big not side is brought to Container Transport material
Just.
The content of the invention
The purpose of the present invention is overcome the shortcomings of the prior art, there is provided a kind of high intensity cleaning PE films and its preparation
Method.
The purpose of the present invention is achieved through the following technical solutions：
A kind of high intensity cleaning PE films, it includes being mixed by common polythene and hp-ldpe from inside to outside successively
Resin material formed anti-puncture internal layer, linear high-density polyethylene strength enhancing middle level and forced down by common polythene and height
The anti-puncture outer layer that the resin material of density polyethylene mixing is formed, the weight ratio of the internal layer, middle level and outer layer is 1:1:1,
And three forms one by casting machine co-extrusion.
Preferably, the hp-ldpe in the internal layer accounts for 1% ~ 3% of quality in total material.
Preferably, the hp-ldpe in the outer layer accounts for 1% ~ 3% of quality in total material.
Preferably, the polytetrafluoroethylene (PTFE) being arranged on the outer layer.
Preferably, the thickness ratio of the internal layer, middle level and outer layer is：1:1.2:1.
Present invention further teaches a kind of preparation method of high intensity cleaning PE films, include the following steps,
The blend step of S1, raw material, send mixing common polythene and hp-ldpe into single screw extrusion machine and are kneaded,
The extruder temperature of the single screw extrusion machine is 150~190 DEG C, and the head temperature of first single screw extrusion machine is 170
~200 DEG C, 40~100 revs/min of the rotating speed of the screw rod, extrudes 30~50Mpa of tonnage, the height forces down close
Degree polyethylene accounts for 1% ~ 3% of quality in total material, forms puncture resistant layer；
S2, three-layer co-extruded step, Hi-fax is three-layer co-extruded as inside and outside two layers progress as intermediate layer, puncture resistant layer
Go out, three layers of fluidised form raw material merges extrusion in the casting machine, forms film bubble, and film bubble is cold under 10~20 DEG C of cooling wind
But it is molded；Film bubble is sent into draw-gear after collapser is pressed into flat and carries out traction stretching, and it is thin to form high intensity cleaning PE
Film.
The beneficial effects are mainly as follows：It is reasonable in design, forced down by increasing height in internal layer and outer layer
Density polyethylene materials can reach the purpose being modified to it, greatly strengthens its anti-puncture ability, is effectively prevented from packaging film and breaks
Damage, causes unnecessary economic loss.Simultaneously as internal layer is made of the linear polyethylene material with high intensity, so that
Its integral strength is greatly enhanced, drastically increase the security used.
Brief description of the drawings
Technical solution of the present invention is described further below in conjunction with the accompanying drawings：
Fig. 1：The structure diagram of the present invention.
Embodiment
Below with reference to embodiment shown in the drawings, the present invention will be described in detail.But these embodiments are simultaneously
The present invention is not limited to, structure that those of ordinary skill in the art are made according to these embodiments, method or functionally
Conversion is all contained in protection scope of the present invention.
As shown in Figure 1, present invention is disclosed a kind of high intensity cleaning PE films, it includes by commonly gathering successively from inside to outside
The anti-puncture internal layer 1 of the resin material formation of ethene and hp-ldpe mixing, linear high-density polyethylene intensity carry
Middle level 2 and the anti-puncture outer layer 3 formed by the resin material that common polythene and hp-ldpe mix are risen, it is described interior
The weight ratio of layer 1, middle level 2 and outer layer 3 is 1:1:1, and three forms one by casting machine co-extrusion.
In the present invention, the hp-ldpe in the internal layer 1 and outer layer 3 accounts for 1% ~ 3% of quality in total material.
Further, the polytetrafluoroethylene (PTFE) being arranged on the outer layer 3 is further included in the present invention, selects polytetrafluoroethylene (PTFE) to be
Because it has higher wearability, corrosion resistance, insulating properties etc..It is of course also possible to select other materials, the present invention is in
Protection domain in.
Preferably, the thickness ratio of the internal layer 1, middle level 2 and outer layer 3 is：1:1.2:1.
Present invention further teaches a kind of preparation method of high intensity cleaning PE films, include the following steps,
The blend step of S1, raw material, send mixing common polythene and hp-ldpe into single screw extrusion machine and are kneaded,
