Abstract
The invention discloses a composite film production process, the surface of kraft paper is coated with a resin binder by a compounding machine, and the resin binder is attached on a polyethylene terephthalate film by heating and rolling; the surface of the kraft paper is coated with a water soluble resin adhesive and a water dispersion resin adhesive, the water soluble resin adhesive and the water dispersion resin adhesive are compounded with the polyethylene terephthalate film, and attached on the polyethylene terephthalate film by roller pressing and drying; the polyethylene terephthalate film is extruded into a thin film by an extruder, the surface of kraft paper is coated and glued with the polyethylene terephthalate thin film for compounding, then cooling and curing; a thin film, paper surface and aluminum foil surface are coated with a heat flux which is obtained by doping rosin, xylene resin, styrene resin and paraffin wax bottom-sticking reducing agent into resin, the thin film, the paper surface and the aluminum foil surface are compounded onto the kraft paper, and then cooled; the production process is simple and practical, and the composite film produced by the production process has the advantages that the colour and lustre is consistent, and miscellaneous points are small, and has a broad market prospect.
Description
Technical field
The present invention relates to membrane material production technology, particularly relate to a kind of production technology of composite membrane.
Background technology
PVC main component is polyvinyl chloride, for micro-yellow is translucent, glossy.Transparency is better than polyethylene, polypropylene, is worse than polystyrene, and different with auxiliary dosage, be divided into soft, PVC-U, soft goods is soft and tough, and feel is glued, and the hardness of boardy product is higher than low density polyethylene (LDPE), and lower than polypropylene, in flexion, place there will be albinism.Common product: sheet material, tubing, sole, toy, door and window, wire outer skin, stationery etc.It is a kind of macromolecular material using a chlorine atom to replace a hydrogen atom in polyethylene.PVC industry in whole world development rapidly; have a extensive future; each state all has an optimistic view of the potentiality of PVC and it is to the benefit of ecological environment; to common people, the performance that PVC is superior with it, unique proves that its function and position is that any other products all cannot replace; social development needs it; environmental protection needs it, and it is the inexorable trend of our civilization of human society progress.
Summary of the invention
The invention provides a kind of production technology of composite membrane.For realizing object of the present invention, technical scheme of the present invention is as follows:
A production technology for composite membrane, is characterized in that, its concrete steps are:
1) resinoid bond is coated on the surface of brown paper by compounding machine, PET is dissolved in absolute ethyl alcohol, the hydration ammonia solution that content is 25% is dripped again in absolute ethyl alcohol, continue after dropping terminates to stir 20-30 minute at 55-65 DEG C, drip ethyl orthosilicate again to continue to stir 15-18 hour, obtain PET film;
2) water-soluble resin binding agent, water-dispersed resin binding agent are coated in brown paper surface, with PET film compound, then echo drying with roll-in and carry out compound.
3) with extruder by PET film extrusion film shape, be coated with and be bonded at brown paper surface in addition compound, then through cooling, solidification.
4) in resin, the hot solvent of blending rosin, xylene resin, styrene resin and paraffin sticky end depressant is coated on film, paper, aluminium foil surface, is compounded on brown paper, then cools.
Preferably, in step 3), chilling temperature controls at 13 DEG C.
Preferably, in step 4), the temperature of hot solvent controls at 80 DEG C.
Beneficial effect: the production technology that the invention provides a kind of composite membrane, its key step comprise dry to mediate-just refining-refining-extrude feeding, calendering-cooling is batched, be sent to extrude feeding machine before filtration treatment is carried out to plasticizing material can remove and not plastify material grain and impurity, carry out the internal stress that Ageing Treatment can eliminate film, this production technology is simple, with the composite membrane of this kind of explained hereafter, there is the advantage that consistent, the assorted point of color and luster is little, there are wide market prospects.
Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
A production technology for composite membrane, is characterized in that, its concrete steps are:

2) water-soluble resin binding agent, water-dispersed resin binding agent are coated in brown paper surface, with PET film compound, then echo drying with roll-in and carry out compound.
3) with extruder by PET film extrusion film shape, be coated with and be bonded at brown paper surface in addition compound, then through cooling, solidification.
4) in resin, the hot solvent of blending rosin, xylene resin, styrene resin and paraffin sticky end depressant is coated on film, paper, aluminium foil surface, is compounded on brown paper, then cools.
In step 3), chilling temperature controls at 13 DEG C.
In step 4), the temperature of hot solvent controls at 80 DEG C.
The invention provides a kind of production technology of composite membrane, its key step comprise dry to mediate-just refining-refining-extrude feeding, calendering-cooling is batched, be sent to extrude feeding machine before filtration treatment is carried out to plasticizing material can remove and not plastify material grain and impurity, carry out the internal stress that Ageing Treatment can eliminate film, this production technology is simple, with the composite membrane of this kind of explained hereafter, there is the advantage that consistent, the assorted point of color and luster is little, there are wide market prospects.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
