Fig. 3 is referred to, Fig. 3 is a kind of paper-plastic stick paper for daily use provided in an embodiment of the present invention
The flow chart of manufacture method, as illustrated, the manufacturer of the paper-plastic stick paper for daily use of the present embodiment
Method is comprised the following steps：
S101：In the hot melt that the wherein surface coating fusing point of PE base film layers is 99-110 DEG C
Glue is forming precoating film layer.
The PUR of low melting point is coated on one of surface of PE base film layers, precoating is formed
Film.Pre- gluing is ethylene-vinyl acetate copolymer (EVA) or ethylene-vinyl alcohol copolymer resin
(EVOH), or modified EVA or EVOH, pre-gelatinized fusing point is 99 DEG C -110 DEG C,
It is close and lower slightly with PE base films fusing point.
S102：The PE base film layers for being coated with precoating film layer are heated, and make precoating film layer
In melting state, PE base film layers are in slush state.
It is coated with pre-gelatinized PE base films heating so that pre- gluing is in melting state, PE
Base film is in slush state.Mode of heating can be that flat heating, hot-air through type add
Heat or other mode of heatings.
When heating-up temperature reaches 99 DEG C -110 DEG C, pre- gluing melted by heating, it is changed into fluid, while PE
Base film is also at slush state, and now pre-coating film is just attached to carrier (such as paper for daily use, nothing
Spin cloth etc.) on, a kind of transition zone is formed between paper and PE films, melt under pressure
The pre- gluing for melting is penetrated into paper and PE films after being extruded, and makes paper and PE film close beds
Close, it is to avoid delamination.
S103：PE base film layers after at least one of which paper and heating are carried out into hot pressing pressing, it is cold
But paper-plastic stick paper for daily use is obtained.
Being pressed by hot pressing makes pre-gelatinized PE base films be combined with paper, with precoating film layer phase
Adjacent paper can be one layer of paper or multi-layered paper.When implementing, heat can be carried out by pressure roller
Pressure pressing.Under pressure roller action condition, the PUR of thawing and the PE base films of slush are received
To extruding, so penetrate into formed in paper it is compound.Pressure between compound tense pressure roller is 0.4MPa
- 1.0MPa, preferably 0.55MPa-0.75MPa.PUR penetrates into the infiltration in paper after extruding
Depth is 0.2-1.5mm, therefore, the paper adjacent with pre- rubberised layer can be one or more layers
Paper.PE film layers and the closely compound paper of at least one of which paper are obtained after cooling, solidification
Compound paper for daily use.
Wherein, in the present embodiment, pressing mode is pre-coating film hot pressing, and hot pressing temperature is 99 DEG C -110 DEG C,
It is preferred that 105 DEG C -110 DEG C.It is fluid that pre- rubberised layer melts at a temperature of this, and PE base films are in half
Melting state.Pressure roller can be plain-barreled roll or knurling rolls, preferably knurling rolls, and knurling rolls are laminated better
And the paper-plastic stick paper for daily use of making is more preferably soft.
Using knurling rolls make paper-plastic stick paper for daily use can not only make PE base film layers and
Paper is combined well, improves the performances such as the anti-tear of paper, waterproof, protection against the tide, and improve
The flexibility of paper-plastic stick paper.Embossed pattern can be point-like, convex, other shapes of
The combination of pattern or different pattern；Embossing depth is 0.2mm-3mm, preferably 0.4mm-1.5mm；
The distance between embossed pattern is 0.5mm-5.0mm, preferably 1.0mm-2.0mm；Embossing part accounts for
The ratio of paper is 10%-80%.
Wherein, in the present embodiment, pre- gluing only can be coated on a surface of PE base materials,
Another surface of PE base films directly bonds paper layer, wherein, in PE bases under this mode
The paper layer that another surface of material film directly bonds is preferably individual layer paper layer.
Realized as another kind, can all coat precoating on two relative surfaces of PE base materials simultaneously
Glue, then carries out above-mentioned plus sintering step again.In this manner it is possible to form PE base film layers
Two relative surfaces all with multi-layered paper bond.
Base film layer is a kind of sealed polyethylene plastic of low melting point (PE) in the present embodiment,
Under the conditions of 110 DEG C or so can melted by heat, can be carried out with paper under supplementary means in embossing etc. it is laminated,
Individual layer is laminated not to be fallen off, can be used as pre-gelatinized diaphragm.The PE base films can be common PE
Film or high-low pressure PE films.Preferred PE films are height press mold.In view of high-low pressure PE films have in itself
There is two-sidedness, high pressure low density face easily melts and increases pre-coating film with paper under hot pressing condition
Conformal effect is played in bonding force, low-pressure high-density face, is unlikely to deform film substrate layer.
When PE base film layers one side of the present invention applies pre- gluing, preferred base material is common
PE films, during the pre- gluing of the two-sided painting of PE base film layers, preferred base material is that high-low pressure PE is thin
Film.
Current paper-plastic stick paper generally uses PP, PET, PVC class material as film substrate, this
The fusion temperature of class film substrate requirement is higher, and the combination process cost of investment such as film, coating is high.
And the present invention uses PE as base material, PE and EVA or EVOH PURs and its modified derivative
The fusing point of thing is relatively low, easily heat-sealing, under the conditions of without auxiliary processes such as embossing, PE precoatings
The two sides of film can carry out closely laminated with paper, and EVA or EVOH hot melt glue surfaces can be with
At least one of which paper carries out closely laminated, that is, increased the paper number of plies of bonding, increased again it is single,
The flexibility of double-face layered paper.The paper-plastic stick type paper for daily use of the embodiment of the present invention is using precoating
Glue form carries out hot pressing and is combined, and without organic solvent, environmental protection, the compound paper for daily use is strong
Degree is high, and tear-resistant, pliability is good, and waterproof, moisture resistance are good.Manufacture method PE of the invention
Base material is short with paper recombination time, adhesion strength is strong, and simple production process, low cost is combined life
Delamination is difficult with paper, therefore expands its range of application.
To further illustrate above-mentioned manufacture method of the invention, below in conjunction with specific embodiment to upper
State manufacture method to be illustrated, embodiment described below is with generation cited by the present invention
Limited embodiment of table, specific material, formula rate and a reaction condition being previously mentioned is not
