Abstract

A method for making self-adhering composite sheet includes such technological steps as immersing non-woven cloth in resin, drying and hardening, sticking it onto both surfaces of an appropriate thermoplastic membrane, and coating adhesive (such as thermosol) on non-woven cloth.

Description

The manufacture method of tool autohension compound foil material

The present invention is a kind of manufacture method of tool autohension compound foil material, especially refer to a kind of with proper method in conjunction with the tNonwovens sheet material, tree refer to and suitably glue-line make the good characteristic that merges these materials in one in one, use to adapt to many-sided autohension (as the footwear internal gasket etc.).

The method for making of tradition autohension compound foil material is with tNonwovens material surface coated adhesive-layer, makes its dry hardened forming, and with the hardness and the easy viscosity of soft plasticity-of tNonwovens and plastic mass; But because the composite sheet of this type is adding man-hour, need be soaked, make whole lamellar body softening and present high viscosity, so that the processing operation with the toluene equal solvent; But well-known, the toluene equal solvent itself has high volatile volatile, if with in these volatile gases suction bodies, can cause certain injury to health; The thin slice section bar that for this reason just has the dealer to develop to form a kind of many stacked systems to make solves the problems referred to above, promptly utilize a thermoplastically material to be main body, fitting with stacked system in the both sides of this main body tNonwovens, resin layer and glue-line more than attached one deck, these utilize lamination to be bonded as the sheet material of one, snappiness with tNonwovens, and thermoplastically material and resin layer strong hardness, then for promptly producing the thermosol utilization of high viscosity after the heating, improving the former just need be with the shortcoming of the softening operation of harmful human body solvent soakings such as toluene for coating appearance glue-line.

Yet the said products still has a distinct disadvantage; Be that processing method is to adopt folded mutually layer by layer mode combination, the combination of each interlayer needs to consider the associativity and the consistency of material, and expected be that the indivedual compatible associativity of tNonwovens and materials such as thermoplastically material, resin or colloid all still can be accepted, but coat on the hardened resin surface with colloid merely, obviously can't reach the result of suitable satisfaction, so these finished products only need can make between the two and separate with suitable peeling force effect, this is a big shortcoming of finished product.

The manufacture method that the purpose of this invention is to provide a kind of brand-new autohension compound foil in the hope of solving the aforesaid drawbacks, cooperates suitably graphic being described in detail as follows now;

Fig. 1 is a manufacturing processed synoptic diagram of the present invention.

Fig. 2 is a finished product structure section synoptic diagram of the present invention.

Fig. 3 is another feasible finished product structure section synoptic diagram of the present invention.

Please refer to the drawing 1, Fig. 2 and Fig. 3, manufacture method of the present invention mainly is the adhesive-bonded fabric with suitable material Sheet material 10 impregnated in suitable hardening resin 20 (such as the acrylic resin), makes the tissue of adhesive-bonded fabric sheet material 10 Inside and outside all impregnation hardening resins 20 and be combined into a combination 21 are again to drench the film mode at above-mentioned combination 21 The side Surface Mount close thermoplasticity material layer 30 (such as polypropylene etc.), more can be thus with plural combination Body 21 is bonded, then again in the appearance coated glue layer 40 (can be thermosol) of combination 21; So in conjunction with processing mode, because adhesive-bonded fabric material 10 is that complete impregnation is combined into one with hardening resin 20 Body, so the applying effect between itself and other materials, the characteristic that can merge both is supplied mutually, namely utilizes and does not knit The good compatible associativity of cloth material and other materials overcomes hardening resin or thermoplasticity material and other glue The relatively poor shortcoming of layer 40 compatible associativity; Therefore, the present invention can not only be effectively in conjunction with the flexibility of adhesive-bonded fabric And the strong hardness of hardening resin and thermoplasticity material, more can allow the associativity of glue-line 40 and aforementioned each interlayer Strengthen, peel off easily the shortcoming that comes off after the improvement adhesion.

In sum, the invention provides a kind of manufacture method of autohension compound foil of novelty, really can solve the relatively poor shortcoming of product bond effect of aforementioned conventional method for making, but obviously possessed the utility value on the industry.
