Abstract
The present invention discloses a laminating process during a flexible polyurethane film production process, wherein the laminating process at least comprises three steps such as glue coating, drying and laminating. According to the present invention, the glue consumption, the drying channel temperature and the compounding distance are strictly controlled, and the produced composite film has characteristics of firm adhering and smooth surface.
Description
Technical field:
The present invention relates to polyurethane laminating technique, be specifically related to the multiple membrane process in a kind of flexibel polyurethane film production process.
Background technology:
During the multiple film of traditional polyurethane film, can face the product quality that different problems causes producing low, the too high meeting of such as bake out temperature causes that PE film is overbated, the part demoulding, and the too low meeting of temperature causes viscosity inadequate.
Summary of the invention:
In order to solve the problem existing for background technology, the present invention is by the following technical solutions:
A multiple membrane process in flexibel polyurethane film production process, at least comprises following three steps:
(1) gluing: the PE film adopting 0.2-0.6mm, and evenly coat Environment-friendlyglue glue in the one side of film, adopt the gap length between the clearance gauge control glue application edge of a knife and cylinder, glue quantity is controlled at 0.08-0.12kg/m
2.
(2) dry: drive the PE film of evenly cloth glue to enter drying tunnel by live roll, evaporate unnecessary moisture.Drying tunnel temperature controls between 90-120 DEG C, is specifically determined by the thickness of PE film and glue and the transfer rate of PE film, produces softening being advisable with PE film body.
(3) multiple film: cavernous body is set level, gap between adjustment constant temperature coating machine two pressure rollers, its gap length=cavernous body static thickness-2mm, recombination rate is 2m/min, smooth for ensureing the surfacing of composite membrane, between pressure roller and PE film, adopt release liners as liner.
The present invention strictly controls glue quantity, drying tunnel temperature and compound spacing, and the composite membrane bonding of production is firm, any surface finish.
Detailed description of the invention:
