Abstract
The object of the invention is to propose a kind of the environment-friendly paper based composites and the processing method thereof that are easy to recycling.Environment-friendly paper based composites of the present invention is composited by PE modified layer, PE layer, adhesive layer, aluminium foil, adhesive layer, PE layer, paper fibrage, adhesive layer, PE layer, and key is that described PE layer is mixed by PE and release agent.The processing method of the above-mentioned environment-friendly paper based composites that the present invention proposes is as follows: PE material and release agent are added in batch mixer and mix, then through extruder hot-melt extruded, curtain coating is compound in adhesive layer, form the composite bed of adhesive layer and PE layer, last again by PE modified layer, aluminium foil, paper fibrage according to paper-based composite material each layer distribution respectively with composite bed compound, obtain paper-based composite material.Environment-friendly paper based composites cost of the present invention is low, easy to be recycled, therefore has good market value, and the processing method technique of environment-friendly paper based composites of the present invention is simple, easy to operate, is convenient to popularize.
Description
Technical field
The invention belongs to paper product manufacturing technology field, be related specifically to a kind of environment-friendly paper based composites and processing method thereof.
Background technology
Existing liquid food aseptic packaging box generally adopts paper-based composite material to make, and this kind of paper-based composite material comprises plastic layer, paper fibrage and aluminium foil, has the advantage that cost is low, fresh keeping property is good, is therefore widely used by the liquid beverage producer.But the plastic layer in this kind of paper-based composite material, paper fibrage cannot thoroughly be separated after a procedure with aluminium foil, easy contaminated environment.Although there is now the method that waterpower is separated, can only recoverer separation fibrage, still plastic layer and aluminium foil cannot be recycled, therefore be necessary to design a kind of paper-based composite material being easy to recycle, to improve its feature of environmental protection.
Summary of the invention
The object of the invention is to propose a kind of the environment-friendly paper based composites and the processing method thereof that are easy to recycling.
Environment-friendly paper based composites of the present invention is composited by PE modified layer, PE layer, adhesive layer, aluminium foil, adhesive layer, PE layer, paper fibrage, adhesive layer, PE layer, and key is that described PE layer is mixed by PE and release agent.
Above-mentioned PE modified layer, adhesive layer, aluminium foil, paper fibrage all can adopt existing Lile packaging material, the present invention improves PE layer by being added in PE layer by release agent, make PE layer and other layer more easily separated, various material is this makes it possible to reclaim respectively, improve recovery utilization rate, make paper-based composite material environmental protection more.
Further, described release agent is tetrapentaerythritol ester (i.e. AT-1010), and the tetrapentaerythritol ester in described PE layer and the weight ratio of PE are 0.5 ~ 1:99 ~ 99.5.Through experimental verification, adopt this kind of release agent each layer can be separated easily completely, recovering effect is best.
The processing method of the above-mentioned environment-friendly paper based composites that the present invention proposes is as follows: PE material and release agent are added in batch mixer and mix, then through extruder hot-melt extruded, curtain coating is compound in adhesive layer, form the composite bed of adhesive layer and PE layer, last again by PE modified layer, aluminium foil, paper fibrage according to paper-based composite material each layer distribution respectively with composite bed compound, obtain paper-based composite material.
Environment-friendly paper based composites of the present invention and traditional paper-based composite material cost are more or less the same, but (utilizing the seperator that market is now sold each layer of paper-based composite material of the present invention can be separated) more easy to be recycled, therefore there is good market value, the processing method technique of environment-friendly paper based composites of the present invention is simple, easy to operate, be convenient to popularize.
Accompanying drawing explanation
Fig. 1 is the structural representation of environment-friendly paper based composites of the present invention.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in Figure 1, the environment-friendly paper based composites of the present embodiment is composited by PE modified layer 9, PE layer 8, adhesive layer 7, aluminium foil 6, adhesive layer 5, PE layer 4, paper fibrage 3, adhesive layer 2, PE layer 1, key is that described PE layer 8,4,1 is mixed by PE and tetrapentaerythritol ester (i.e. AT-1010), and the tetrapentaerythritol ester in PE layer 8,4,1 and the weight ratio of PE are 0.5 ~ 1:99 ~ 99.5.
Above-mentioned PE modified layer 9, adhesive layer 7,5,2, aluminium foil 6, paper fibrage 3 all can adopt existing Lile packaging material, the present invention improves PE layer by being added in PE layer by release agent, make PE layer and other layer more easily separated, various material is this makes it possible to reclaim respectively, improve recovery utilization rate, make paper-based composite material environmental protection more.
The processing method of the above-mentioned environment-friendly paper based composites that the present invention proposes is as follows: PE material and release agent are added in batch mixer and mix, then through extruder hot-melt extruded, curtain coating is compound in adhesive layer, form the composite bed of adhesive layer and PE layer, last again by PE modified layer, aluminium foil, paper fibrage according to paper-based composite material each layer distribution respectively with composite bed compound, obtain paper-based composite material.
