Abstract

The utility model relates to an improved structure for a self-adhesive composite thin-sheet material. A non-woven fabric sheet material made of proper materials is solubilized and attached with a material layer film sheet with the low-density polyethylene and the equal heat plasticity through a film showering method, then is showering coated with a proper adhesive layer on the non-woven fabric sheet material, and a self-adhesive composite thin sheet is formed and has the flexibility of the non-woven fabric and the characteristics of the polyethylene, such as hardening, etc. Then the surface of the adhesive layer is pressed with patterns, and the patterns are used for promoting the adhesive performance and are beneficial for the interval gas removal of the adhesive procedure.

Description

The improvement structure of tack THIN COMPOSITE sheet material

The utility model is a kind of improvement structure of tack THIN COMPOSITE sheet material, especially refer to a kind of with proper method in conjunction with the adhesive-bonded fabric sheet material, polyethylene (thermoplasticity material layer) and suitable glue-line are in one, make these material good characteristics of certain fusion in one, use to adapt to many-sided tack (as the footwear internal gasket etc.), and, make the cohesive that can promote each material interlayer and the eliminating of applying process bubble, to improve the applying effect at above-mentioned colloid face compacting all over design.

The form of tradition tack compound foil material is with adhesive-bonded fabric material surface coating adhesive-layer, makes its dry hardened forming, and with the hardness and the easy viscosity of soft plasticity of adhesive-bonded fabric and gel; But because the composite sheet of this type is adding man-hour, need to be soaked with the toluene equal solvent, make whole lamellar body softening and present high viscosity, so that processing operation, but well-known, the toluene equal solvent itself has high volatile volatile, if with in these escaping gas suction bodies, can cause certain injury to health; For this reason, the thin slice section bar that 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 thermoplasticity material to be main body, fitting with stacked system in the both sides of this main body adhesive-bonded fabric, resin bed and glue-line more than attached one deck, these utilize lamination to be bonded as the sheet material of one, true pliability with adhesive-bonded fabric, and thermoplasticity material and resin bed strong hardness, then for promptly producing the thermosol utilization of high viscosity after heating, just foot improves the shortcoming that the former needs to soften with harmful human body solvent soakings such as toluene operation to coating appearance glue-line.

Yet above-mentioned improved goods but 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 compatibility of material, and expected be that adhesive-bonded fabric and heat must plastic materials, the indivedual compatible associativity of material such as resin or colloid is all along still accepting, but coat on the resin surface of sclerosis with colloid merely, obviously can't reach the result of suitable satisfaction, so these finished products only need with suitable peeling force effect, can make between the two and separate, this is a big shortcoming of manufactured goods, and above-mentioned glue-line is a flat surfaces, and the applying of taping process is grabbed heat thermosol speed and bubble elimination ability of system power and all is subjected to suitable puzzlement.

The purpose of this utility model provides a kind of structure of brand-new tack compound foil, in the hope of solving above-mentioned shortcoming.Now cooperate suitably graphic state clearly in detail as follows:

Fig. 1 is a manufacture process schematic diagram of the present utility model;

Fig. 2 is a manufactured goods structure section schematic diagram of the present utility model;

Fig. 3 is the utility model taping process structure section schematic diagram;

Fig. 4 is the taping process structure section schematic diagram of traditional structure;

See also Fig. 1 and Fig. 2, the utility model mainly is the adhesive-bonded fabric sheet 10 with suitable material, to drench film Mode is in the above in conjunction with one deck thermoplasticity material diaphragm 20 (can be low density polyethylene (LDPE)), to form one Combination 21, appearance showering one gelatinous layer 30 (can be thermosol) of above-mentioned thermoplasticity material diaphragm 20, And the appearance compacting decorative pattern 40 (can be netted all over design) of this gelatinous layer 30 is like this, the utility model Not only effectively in conjunction with the strong hardness of adhesive-bonded fabric flexibility and thermoplasticity material diaphragm 20, can allow again gelatinous layer 30 Because of the embossing operation, strengthen with the associativity of aforementioned each interlayer, peel off easily the shortcoming that comes off after the improvement adhesion.

Secondly, see also Fig. 3 and Fig. 4 and in conjunction with Fig. 1 and Fig. 2, because embossing 40 is made on the utility model gelatinous layer 30 surfaces, make whole binding face when overlaying, be able to the appropriate system applying power of grabbing that enlarges and strengthen, and be understandable that the thermosol time is shortened, improve process velocity, because the existence of continuity embossing 40, for overlaying process, and the air that laminated material is 50 can have enough pipelines to get rid of successively, improves the shortcoming that reduces viscosity because of air gap, shows that all this design can improve whole stickiness, when improving traditional applying, heating for dissolving length consuming time, grab the shortcoming person that system power is relatively poor and retain bubble 31 easily.

In sum, the utility model provides a kind of tack compound foil structure of novelty, really can solve aforementioned conventional product shortcoming, but has obviously possessed the value on the industry.
