Abstract
The invention discloses a wrapping paper surface lamination process which comprises the following steps: one side of an EVA (ethylene-vinyl acetate) film is coated with glue; the glued EVA film flatly covers wrapping paper requiring lamination, and the EVA film is softened under the action of high temperature; the wrapping paper and the EVA film are placed into a lower mold together, and an upper mold presses down; the wrapping paper is taken off from the mold, heated, cooled and deburred to obtain a finished product. The process is simple to operate and low in cost; a paper-plastic product after lamination has attractive appearance as well as smooth, flat and elastic surface, and the strength, toughness and buffer performance of the product are improved greatly.
Description
Technical field
The present invention relates to coating technique field, particularly a kind of wrapper surface coating technique.
Background technology
Traditional paper pulp moulding product is all one-sided smooth, and one side is more coarse, and general paper pulp moulding product poor toughness, easily fracture and be out of shape.And traditional coating technique is all carry out between the product of two kinds of planes, as between paper and plastic foil or between harmless cloth and expanded polyethylene foam.Concavo-convex surface treatment only has spraying and flocking two kinds and cost is very high, can only play the effect of any surface finish.A technological gap by laminating for the material of the plane surface at concavo-convex product.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of wrapper surface coating technique, and improve surface smoothness, intensity, toughness and shock-absorbing capacity, make it reusable to solve in prior art the above-mentioned multinomial defect caused.
For achieving the above object, the invention provides following technical scheme: a kind of wrapper surface coating technique, specifically comprises the following steps:
1) be arranged on respectively on hydraulic press by the upper and lower mould of overlay film mould, mold temperature is 25 DEG C;
2) by coated on one side one deck glue of EVA film thick for 2-3mm;
3) need on the wrapping paper of overlay film by smooth for the EVA film after gluing covering, both are long by a 10m together, and temperature is the drying tunnel of 120-140 DEG C, and EVA film is softening under the effect of high temperature;
4) wrapping paper is put into counterdie together with EVA film, patrix is depressed, upper and lower mould matched moulds 10s, and the EVA film after gluing is at high temperature softening meets the sizing of cold mould, is bonded in the surface of wrapping paper under the effect of pressure and glue;
5) taken off from mould by the wrapping paper after laminating, at the temperature of 50 DEG C, heat 150s, after cooling, pare off burr, finished product completes.
Preferably, in step 3), by smooth for the EVA film after the gluing surface covering wrapping paper, form one side film.
Preferably, in step 3), by the smooth upper and lower surface covering wrapping paper respectively of the EVA film after gluing, form two-sided overlay film.
The beneficial effect of above technical scheme is adopted to be: technological operation of the present invention is simple, with low cost, can one side film, also can two-sided overlay film.Specious by the paper products after present invention process overlay film, smooth surface is smooth and flexible, intensity, toughness, shock-absorbing capacity improves greatly, product after two-sided overlay film matches in excellence or beauty large-scale sheet blister plastic packaging goods in performance, and ageing-resistant performance and buffering protective value are better than Blister product, and cost is 1/5th of plastic products; Meanwhile, paper and EVA are biodegradable, belong to environment-friendly materials, are convenient to outlet.
Detailed description of the invention
The following detailed description of the preferred embodiment of the present invention.
The specific embodiment of the present invention: a kind of wrapper surface coating technique, specifically comprises the following steps:
1) be arranged on respectively on hydraulic press by the upper and lower mould of overlay film mould, mold temperature is 25 DEG C;
2) by coated on one side one deck glue of EVA film thick for 2mm;
3) smooth for the EVA film after gluing covering is needed on the wrapping paper of overlay film, both are long by a 10m together, temperature is the drying tunnel of 130 DEG C, EVA film is softening under the effect of high temperature, by smooth for the EVA film after the gluing surface covering wrapping paper, form one side film, by the smooth upper and lower surface covering wrapping paper respectively of the EVA film after gluing, form two-sided overlay film;
4) wrapping paper is put into counterdie together with EVA film, patrix is depressed, upper and lower mould matched moulds 10s, and the EVA film after gluing is at high temperature softening meets the sizing of cold mould, is bonded in the surface of wrapping paper under the effect of pressure and glue;
5) taken off from mould by the wrapping paper after laminating, at the temperature of 50 DEG C, heat 150s, after cooling, pare off burr, finished product completes.
EVA formal name used at school is ethane-acetic acid ethyenyl (vinyl acetate) ester copolymer, is called for short EVA or E/VAC.The feature of EVA vacuolar membrane is exactly have good flexibility, and the elasticity as rubber and toughness are biodegradable, thermoplasticity and good coating performance.These good performances make it and male and fomale(M&F) is laminating creates possibility.
Technological operation of the present invention is simple, with low cost, can one side film, also can two-sided overlay film.Specious by the paper products after present invention process overlay film, smooth surface is smooth and flexible, intensity, toughness, shock-absorbing capacity improves greatly, product after two-sided overlay film matches in excellence or beauty large-scale sheet blister plastic packaging goods in performance, and ageing-resistant performance and buffering protective value are better than Blister product, and cost is 1/5th of plastic products; Meanwhile, paper and EVA are biodegradable, belong to environment-friendly materials, are convenient to outlet.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
