Description
Technical field
The present invention relates to a kind of method making composite membrane is and in particular to a kind of use water-soluble glue makes the side of composite membrane
Method.
Background technology
The coating complex method of non-woven fabrics and PE film adopts traditional solvent-type film-covered adhesive, with science all the time mostly
The development aqueous laminating adhesive gradual perfection molding of technology, people more recognize the harm that solvent-type film-covered adhesive is brought：To behaviour
Make workman's damaging greatly, because the benzene class in solvent and esters can enter the body fluid of people from the body surface of people, and then enter the blood of people
Liquid, heavy dose of contact for a long time causes to accumulate too much in vivo, thus causing various diseases；Inflammable and explosive, hazard rating is high, state
Inside therefore cause heavy losses appear in the newspapers repeatly to；High cost；Increase VOC (volatile organic matter matter) discharge, environment is made
Become pollution；In product, solvent is remaining for a long time, endangers later stage user.And aqueous laminating adhesive successfully overcomes disadvantage mentioned above, tool
There is product viscosity low, transparency is good, combined strength bination is high, steady quality is easy to use, do not have foaming, delamination, yellowing, wrinkling
Etc. phenomenon, and glue is dry rear colourless, tasteless, nontoxic, pollution-free, is a kind of environmental type Laminating adhesive.
Traditional coating machine kept watch by the way of aerator feeding drying tunnel heated, and then drying coated after base
Body.But in the method using aqueouss peritoneum glue, need the moisture carrying in baking water peritoneum glue rapidly and efficiently, at present
Generally existing drying efficiency is low, the problem of drying time length, and drying efficiency lowly directly limit the speed of production of coating process,
The drying rate of prior art is only capable of reaching 20 ms/min.It is badly in need of the new side providing a kind of use water-soluble glue to make composite membrane
Method, to significantly improve speed of production.
Content of the invention
It is an object of the invention to provide a kind of method that use water-soluble glue makes composite membrane, to solve at present using solvent
Type Laminating adhesive makes the big shortcoming of composite membrane toxicity, and the technique speed making PE film, nonwoven fabrics composite film using water-soluble glue
Spend slow problem.
