Abstract
The invention discloses a dissolvent-free composite film preparation method. Firstly, a printing layer and an intermediate structural layer are compounded through a dissolvent-free adhesive layer to obtain a composite film, and then the composite film and a heat-sealing layer are compounded through the dissolvent-free adhesive layer, wherein the dissolvent-free adhesive layer is made of a dual-component dissolvent-free polyurethane agent, adopts polyisocyanate as a main agent and a terminal hydroxyl polyether glycol as a hardener; the printing layer is a bidirectional stretching polyethylene terephthalate film or a bidirectional stretching polypropylene film; the intermediate structural layer is an aluminized polyester film; the heat-sealing layer is a polyethylene film or a polypropylene film. The dissolvent-free composite film preparation method causes no dissolvent volatilization, and is safe in use and environmental-friendly; the pallet oven dissolvent removal is needless, accordingly, the preparation method belongs to an energy saving and emission reduction technique; the production efficiency is high, and the method is suitable for automatic production line; the product cost is lowered due to no dissolvent.
Description
Technical field
The present invention relates to package compound film manufacturing method, be specifically related to a kind of solvent-free composite membrane manufacture method.
Background technology
In plastic flexible package industry, modal Film laminated mode is carried out film with adhesive compoundly exactly, obtains the different package compound film of various properities.The adhesive that wherein used, bi-component polyurethane adhesive is the kind that kind is maximum, consumption is maximum, purposes is the widest.Bi-component polyurethane adhesive is by there being solvent-free solvent-borne type and the large class of no-solvent type 2 of being divided into.Solvent borne polyurethane adhesive technology is ripe, but resource is not only wasted in the volatilization of organic solvent, also can threatening environment and production safety.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, solvent-free composite membrane manufacture method is provided.
Solvent-free composite membrane manufacture method, carries out printed layers and intermediate structure layer compoundly with the first solvent-free adhesive layer, resulting composite membrane carries out compound with hot sealing layer with the second solvent-free adhesive layer again.
The first described solvent-free adhesive layer and the second solvent-free adhesive layer are double component solvent-free type polyurethane adhesive, and its host is polyisocyanates, the PPG that curing agent is terminal hydroxy group.
Described printed layers is biaxial tension PETG film or biaxially oriented polypropylene film.
Described intermediate structure layer is aluminized polyester film.
Described hot sealing layer is polyethylene film or polypropylene screen.
Beneficial effect of the present invention:
The first, solvent-free volatilization, use safety and environmental protection;
The second, without drying tunnel, remove desolventizing, belong to energy-conserving and emission-cutting technology;
Three, production efficiency is high, is applicable to automatic production line;
Four, owing to there is no solvent, reduced product cost.
Accompanying drawing explanation
Fig. 1 is by the structural representation of the solvent-free composite membrane of the present invention's manufacture,
In figure, comprise printed layers 1, intermediate structure layer 2, the solvent-free adhesive layer 4.2 of the solvent-free adhesive layer 4.1, second of hot sealing layer 3, first.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
embodiment 1
First printed layers 1 and the solvent-free adhesive layer 4.1 of intermediate structure layer 2 use first are carried out compoundly, resulting composite membrane carries out compound with the solvent-free adhesive layer 4.2 of hot sealing layer 3 use second again.The first described solvent-free adhesive layer 4.1 and the second solvent-free adhesive layer 4.2 are double component solvent-free type polyurethane adhesive, and its host is polyisocyanates, the PPG that curing agent is terminal hydroxy group; Printed layers 1 is biaxial tension PETG film; Intermediate structure layer 2 is aluminized polyester film; Hot sealing layer 3 is polyethylene film.
embodiment 2
First printed layers 1 and the solvent-free adhesive layer 4.1 of intermediate structure layer 2 use first are carried out compoundly, resulting composite membrane carries out compound with the solvent-free adhesive layer 4.2 of hot sealing layer 3 use second again.Wherein the first solvent-free adhesive layer 4.1 and the second solvent-free adhesive layer 4.2 are double component solvent-free type polyurethane adhesive, and its host is polyisocyanates, the PPG that curing agent is terminal hydroxy group; Printed layers 1 is biaxially oriented polypropylene film; Intermediate structure layer 2 is aluminized polyester film; Hot sealing layer 3 is salivation polypropylene screen.
