Abstract

The utility model provides a waterborne environmental protection sole, include the last extremely lower upper strata of superimposed sole in proper order of follow, sole middle level and sole lower floor medial upper surface of sole and lower surface are provided with a plurality of convex parts respectively, and the lower surface on sole upper strata with the upper surface of sole lower floor then be provided with with each convex part assorted concave part, and be in between sole upper strata and the sole middle level and it has a waterborne polyurethane gluing agent layer to adhere respectively between sole middle level and the sole lower floor. The utility model discloses an agent of waterborne polyurethane gluing is adhere, compares with prior art's solvent sole, and its organic solvent who contains less much to safer, environmental protection, simultaneously through setting up the convex part and the concave part that can match each other on the sticky interface of each level, but the adhesive surface between each level of greatly increased is long -pending, thereby using the adhesive strength that can effectively promote this each level of sole under the same prerequisite of gluing kind, reduces the emergence of the sole condition of coming unstuck.

Description

A kind of aqueous, environmental protective sole

Technical field

This utility model relates to footwear material technical field, a kind of aqueous, environmental protective sole of concrete offer.

Background technology

The structure of sole is considerably complicated, the most in the broadest sense, it may include all compositions such as outer bottom, the middle end and heel The material of bottom.For narrow sense, for the most only referring to outer bottom, the common characteristic of general material for sole of shoe should possess Wear-resisting, water-fast, oil resistant, heat-resisting, pressure, impact resistance, good springiness, easily it is suitable for after foot type, sizing not Flexible type, insulation, easily absorption dampness etc., the end in simultaneously more coordinating, have braking action when the change of feet on foot It is unlikely to slip and be prone to terms and conditions such as stopping.

In the production process of sole, in order to outer bottom, the middle end, are effectively combined with heel, it will usually use molten Dosage form footwear glue is adhesively fixed, but, this solvent-borne type sole produced contains substantial amounts of methyl first The organic solvents such as amide, toluene, butanone, these solvents not only can produce serious pollution to environment, more It is can affect people healthy, therefore hinders development and the application of molten Ji type sole.On existing market Occur in that a lot of aqueous sole using aqueous footwear glue, owing to not containing or containing minimal amount of organic solvent And the most safe and environment-friendly, but, owing to the aqueous footwear glue gluing intensity of prior art is not enough, and sole Use intensity higher, the most usually there will be the phenomenon of sole degumming, hamper the popularization of aqueous sole.

Utility model content

Therefore, in order to solve the problem that prior art exists, this utility model provides one to have higher intensity Aqueous, environmental protective sole.

For solving this technical problem, this utility model takes below scheme: a kind of aqueous, environmental protective sole, including Sole upper strata, sole middle level and the sole lower floor being sequentially overlapped from top to bottom, at the upper table in described sole middle level Face and lower surface are respectively arranged with a plurality of protuberance, and under the lower surface and described sole on described sole upper strata The upper surface of layer is then provided with the recess matched with each protuberance, and in described sole upper strata and sole middle level Between and described sole middle level and sole lower floor between be bonded with an Aqueous Polyurethane Adhesives layer respectively.

Improve further: described sole upper strata includes flexible polyurethane foaming layer.

Improve further: described sole middle level includes EVA foaming layer.

Improve further: described sole lower floor includes abrasive rubber layer.

Improve further: the thickness of described Aqueous Polyurethane Adhesives layer is 1.3-2.5mm.

By using preceding solution, useful aspect of the present utility model is: each level of this utility model The particular design of sequence is to draw through repetition test, is not simple superposition, and this sole uses aqueous polyurethane Adhesive bonds, compared with the solvent sole of prior art, and the organic solvent much less that it contains, from And more safe and environment-friendly, this sole can be mutually matched by setting on the gluing interface of each level simultaneously Protuberance and recess, the gluing area can being greatly increased between each level, thus using the premise of identical glue kind Can effectively promote down the adhesive strength of each level of this sole, reduce the generation of sole degumming situation, be more beneficial for The popularization of aqueous sole.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model embodiment.

Detailed description of the invention

In conjunction with the drawings and specific embodiments, this utility model is further illustrated.

With reference to Fig. 1, the open a kind of aqueous, environmental protective sole of this utility model embodiment, including folding the most successively Sole upper strata 1, sole middle level 2 and the sole lower floor 3 added, in the upper and lower surface in described sole middle level 2 Being respectively arranged with a plurality of protuberance 4, the most described protuberance 4 is directly by by sole middle level 2 pressing mold Be molded with, lower surface on described sole upper strata 1 and the upper surface of described sole lower floor 3 be then provided with The recess 5 that each protuberance 4 matches, in the present embodiment, described recess 5 is directly by by sole upper strata 1 Be molded with sole lower floor 3 pressing mold, and between described sole upper strata 1 and sole middle level 2 with in described sole Layer 2 and sole lower floor 3 between be bonded with an Aqueous Polyurethane Adhesives layer 6 respectively, for by sole upper strata 1, Sole middle level 2 and sole lower floor 3 being bonded into one structure, the most described aqueous polyurethane gluing The thickness of oxidant layer 6 is 1.8mm, in actual production, as long as the thickness of this Aqueous Polyurethane Adhesives layer 6 exists The purpose of this utility model all can be implemented between 1.3-2.5；

In the present embodiment, flexible polyurethane foaming layer is selected on described sole upper strata 1, can play the effect of buffering, Improve comfort level；

In the present embodiment, EVA expanded material is selected in described sole middle level 2；

In the present embodiment, described sole lower floor 3 is then to select abrasive rubber material, has good wear-resisting effect Really.

By using preceding solution, useful aspect of the present utility model is: each level of this utility model The particular design of sequence is to draw through repetition test, is not simple superposition, and this sole uses aqueous polyurethane Adhesive bonds, compared with the solvent sole of prior art, and the organic solvent much less that it contains, from And more safe and environment-friendly, this sole can be mutually matched by setting on the gluing interface of each level simultaneously Protuberance and recess, the gluing area can being greatly increased between each level, thus using the premise of identical glue kind Can effectively promote down the adhesive strength of each level of this sole, reduce the generation of sole degumming situation, be more beneficial for The popularization of aqueous sole.

Although specifically showing in conjunction with preferred embodiment and describing this utility model, implement this technical side Case method and approach are a lot, and the above is only preferred implementation of the present utility model, but art Technical staff should be understood that at the spirit of the present utility model limited without departing from appended claims and model In enclosing, this utility model can be made a variety of changes in the form and details, be of the present utility model Protection domain.
