The specific embodiment
Below in conjunction with the specific embodiment, the present invention is further detailed explanation.
As shown in Figure 1, one-body molded sole provided by the invention, by EVA upper strata 1, adhesive coating 2 and rubber lower 3, formed, by heating mould and the mode that applies mold pressing, EVA upper strata 1, adhesive coating 2 and rubber lower 3 are carried out to hot pressing, each weight proportion of described adhesive coating 2 is: natural gum 10---12%, butadiene rubber 10---12%, white cigarette 20---25%, EVA 45---50%, Zinc Oxide 2.5---3%, anti-wear agent 0.5---0.6%, activating agent 2-3%, stearic acid 0.8---1% and resin 6---7%.Particularly, described natural gum is natural gum 3L, described butadiene rubber BR9000, and described EVA is EVA7470, and described anti-wear agent is anti-wear agent HP158, and described activating agent is activating agent PEG4000, and described stearic acid is ST stearic acid, described resin is resin M 60.
Wherein, each weight proportion on described EVA upper strata 1 is: EVA 60---63%, POE 8---10%, PE 5---7%, talcum powder 18---20%, Zinc Oxide 0.6---0.8%, stearic acid 0.4---0.6%, adhesion agent 0.5-0.7% and flowable 1---2%.Particularly, described EVA is EVA460, described in, described POE is POE8480, and described talcum powder is talcum powder TH108, and described stearic acid is ST stearic acid, and described adhesion agent is adhesion agent HT-01, described flowable is flowable YC-100.
Wherein, each weight proportion of described rubber lower 3 is: natural gum 10---12%, butadiene-styrene rubber 10---12%, butadiene rubber 30---32%, EVA 5---6%, white cigarette 27---30%, naphthenic oil 6-8%, activating agent 5---7%, nanometer calcium 5---6%, Zinc Oxide 4-5%, stearic acid 0.4---0.5%, age resistor 1.4---1.6%, paraffin 0.4---0.5% and resin 0.5-0.7%.Particularly, described natural gum is natural gum 3L, described butadiene-styrene rubber is styrene butadiene rubber sbr 1502, described butadiene rubber is butadiene rubber BR9000, described EVA is EVA7470, described activating agent comprises that weight proportion is the activating agent DEG of 2---3% and the activating agent PEG4000 that weight proportion is 3---4%, described nanometer calcium is nanometer calcium CCR, described stearic acid is ST stearic acid, described age resistor comprises that weight proportion is the antioxidant SP of 0.5---0.6% and the antioxidant MB that weight proportion is 0.9---1%, and described resin is resin M 60.
Adhesive coating 2 provided by the invention is that primary raw material becomes adhesive coating by mixed refining process by EVA and rubber, is used in bonding with rubber of EVA; Preparation method is as follows: according to each weight proportion of adhesive coating described above 2, prepare required material, utilize profit to take machine by mixing 25～30 minutes of mixed material, temperature is got to 95 ℃～100 ℃, then utilizes rubber mixing machine to be processed as the glued membrane that 0.3～0.5 ㎜ is thick blend glue stuff; This adhesive coating 2 has following advantage with respect to traditional glue: one, this kind of glued membrane can replace the glue that traditional shoe-making process is used. not only environmental protection but also save cost of labor; Two, this kind of glued membrane directly fired on rubber lower sheet, than traditional rubber beat slightly, brush coating reduces manual work flow process, the bonding force of avoiding human negligence to cause is not enough; Three, this synthetic glued membrane can make more than EVA and the rubber pulling force after mould heat pressure reaches 4 ㎏/㎝, and uses the pulling force of glue to be generally 3 ㎏/㎝ left and right; Four, in order to alleviate the weight of sport footwear, existing increasing rubber-sole adopts a lot of small pieces, and traditional rubber is beaten slightly, brush coating cannot complete, and adopts synthetic glued membrane directly to fire in rubber-sole, then can complete through hot pressing is one-body molded with EVA.
The processing step of one-body molded sole is as follows: one, will synthesize glued membrane, and with die, be cut into required shape and big or small standby; Two, the raw material being made into by each weight proportion of rubber lower is put into mould, the synthetic glued membrane of getting ready is lain on raw material, through being hot pressed into rubber lower (temperature of mould need reach more than 140 ℃); Three, the rubber lower baking is inserted to position corresponding in EVA mould, then the material that each weight proportion on EVA upper strata is made into is put into mould (mold temperature need reach more than 140 ℃) through hot-forming.Through test manufacture for a long time, our obtain-optimum heating temperature is 140-160 ℃, applies mold pressing optimum value 70-80KG/CM
2.
As shown in Figure 2, the pulling experiment data of the tension of the sole of producing for one-body molded sole of the present invention and traditional approach, as seen from Figure 2, use the tension pulling force of adhesive coating more much larger than using the tension pulling force of glue, in the actual use procedure of shoes, the situation that the sole that adopts adhesive coating to make comes unglued does not almost have, and the situation that the sole that uses glue to make comes unglued is very common.
Traditional bonding mode of employing glue, because glue is easily loss and volatile of liquid, makes its bonding effect poor, easily comes unstuck.The adhesive coating that the present invention adopts composite material that EVA and rubber are primary raw material to make is the cointegrate of rubber and plastic, nontoxicity; By heating mould and the mode that applies mold pressing, make its fusing, then carry out hot pressing with rubber lower and EVA upper strata, the bonding place between rubber lower and EVA upper strata can not produce space like this, and bonding compactness is better, and bonding tensile strength is better; Because this composite material contains EVA composition and EVA upper strata carries out having superpower bonding force after hot pressing, contain again rubber constituent and rubber lower and carry out also thering is superpower bonding force after hot pressing, so just make rubber lower and EVA upper strata is molten is integrated, substantially overcome the large end and the middle end phenomenon of coming unglued, it adopts mechanization production in process of production, can save a large amount of human costs, and overcome in traditional production technology health is threatened, improve the production environment of factory.
The above embodiment has only expressed embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
