Description

The technique that a kind of rubber cement and the rubber cement are applied to the bonding of EVA shoe bottom Method
Technical field
The present invention relates to a kind of binding agent and its using method, and in particular to the rubber bound in the manufacturing process of EVA shoe bottom Agent and the EVA shoe bottom adhesion process field using the rubber cement.
Background technology
At present in shoe-making field, traditional shoe sole production mode generally includes rubber-sole production procedure, bottom production in EVA Flow process, rubber-sole are fitted with bottom in EVA three big step of flow process.The wherein first step, rubber-sole production procedure need first to output rubber Mould, rubber-sole dispensing is put into banbury mixing then, and thickness goes out rubber sole sheet as requested, is put into rubber after appropriate cutting In mould, matched moulds pressurization carries out vulcanizing, repair flash makes rubber-sole finished product, then beats thick through rubber-sole or washes, spreading glue And cross oven cooking cycle；Second step, is respectively necessary for outputing bottom finishing die in EVA foaming moulds and EVA in EVA in the production procedure of bottom Tool, concrete steps need first to extrude EVA particles after bottom production dispensing mix homogeneously in EVA in banbury, then by EVA grains During son is put into EVA foaming moulds, matched moulds foamable makes bottom germule block in the EVA for having foamed, and after beating slightly places into middle bottom In finished product die, bottom in EVA is made in matched moulds pressurization, subsequently standby through repair flash, washing, brush coating water, the step such as oven cooking cycle excessively again With；3rd step, bottom in the rubber-sole finished product and EVA of the spreading glue produced in above-mentioned two step is fit together, by pressing bottom Machine pressure bottom can just complete whole rubber soles processing technology.
There is following defect in now traditional EVA shoe bottom production technology：First, traditional handicraft process needs to issue three altogether Mold, and the expense for issuing mould is more considerable, if can save number of molds in process of production as far as possible, is not merely able to Simplify technique, it is often more important that production cost can be saved；2nd, bottom production in rubber-sole production procedure and EVA in traditional handicraft All it is respectively necessary for finished product is carried out beating thick, washing, spreading glue, crosses the steps such as baking box, tedious process in flow process；3rd, in rubber Need to be vulcanized and deburring in the manufacturing process of bottom, can so cause the waste of rubber leftover pieces.Therefore, in line with reduces cost, The principle of saving of work and time, in addition it is also necessary to have more preferable production technology to substitute traditional handicraft.
The content of the invention
It is an object of the invention to provide it is a kind of can it is cost-effective, and save time, the EVA shoe bottom production technology of saving of labor and Rubber cement used in the production technology.
Technical scheme is as follows：
A kind of rubber cement, it is characterised in that rubber cement each group distribution ratio by weight percentage is：Bullet Property resin 60% ~ 65%；Naphthenic oil 3% ~ 6%；EVA 8%~12%；Lactoprene 8% ~ 12%；White carbon 12% ~ 18%.
Rubber cement each group distribution ratio by weight percentage is：Elastic resin 62%；Naphthenic oil 3%；EVA 10%；Lactoprene 10%；White carbon 15%.
Rubber cement each group distribution ratio by weight percentage is：Elastic resin 60%；Naphthenic oil 5%；EVA 8%； Lactoprene 12%；White carbon 15%.
Rubber cement each group distribution ratio by weight percentage is：Elastic resin 64%；Naphthenic oil 5%；EVA 11%；Lactoprene 8%；White carbon 12%.
The elastic resin is SBS elastic resins or TPU elastic resins；Naphthenic oil is Pentamethylene.；Lactoprene is IR- 2200。
Described rubber cement is applied to the process of EVA shoe bottom bonding, comprises the steps：
1）Rubber cement described in claim 1 ~ 5 any claim is pressed with the rubber compounding for making rubber soles According to 6 ~ 10：90 ~ 100 part by weight is weighed, and puts into banbury mix homogeneously, and mixing temperature is 90 ~ 1200C, incorporation time are 5 ~10min；
2）By the rubber sole sheet containing the rubber cement after mixing according to desired thickness slice, and with die according to institute Need shape cutting molding；
3）The rubber sole sheet of the cutting molding is put in EVA in the finished product die of bottom, is then placed into pre-processed EVA in bottom germule block；
4）Pressure is forced into containing bottom finished product die matched moulds in the EVA of bottom germule block in rubber sole sheet and EVA it is by above-mentioned 100kg/CM2, heating-up temperature is more than 155 DEG C, and pressing time is 8 ~ 12 min, then by mould room temperature water cooling 8 ~ 12 Min, takes out the EVA that the rubber sole sheet of the forming is adhered together with bottom germule block in EVA from EVA in the finished product die of bottom Finished product EVA shoe bottom is formed after sole burr removing.
Preferably, 1 the step of the adhesion process method of EVA shoe bottom）Middle rubber cement and the rubber for making rubber soles Formula weighs part by weight for 8：92, the mixing temperature for putting into banbury is 100 DEG C, and incorporation time is 7min；Step 4）Middle conjunction Temperature when mould pressurizes is 155 DEG C ~ 210 DEG C, and the time is 10min, then by mould room temperature water cooling 10min.
Preferably, step 4）Heating-up temperature when middle matched moulds pressurizes is 180 DEG C.
In rubber cement of the present invention, the main component of main component white carbon is SiO2。
Bottom finished product die in EVA：Bottom semi-finished product in EVA are molded into into the mould of bottom finished product in EVA.
Rubber mold：Refer to by rubber compression molding for rubber sole sheet mould.
EVA foaming moulds：EVA particles are foamed into the mould of the EVA semi-finished product for being close to Bottom Shape in finished product, that is, Make the mould of bottom germule block in EVA.
Germule block in bottom in EVA：Finger is close in finished product bottom semi-finished product in the EVA of Bottom Shape by what is foamed, is put into bottom in EVA It is called EVA germule blocks before mould molding, after the completion of molding, is bottom finished product in EVA.
Bottom in EVA：Bottom germule block in EVA is put into the finished product in EVA in the finished product die of bottom after compression molding by finger.
It is an advantage of the invention that：
1st, without opening rubber-sole mould, save die cost.
2nd, without rubber compression molding flow process, simple flow, less manpower and manufacturing expense, save the damage of molding rubber-sole burr Consumption.
3rd, the flow process of fitting without rubber-sole with bottom in EVA, it is not necessary to using any solvent and glue, saving of labor saves expense, green Colour circle is protected.
4th, using the rubber and plastic binding agent that oneself is researched and developed, rubber-sole is also fine with bottom adhesion effect in EVA.
To sum up:Rubber mold is needed out in traditional process, per mold about $ 1400, molding a pair of glue bottom about $ 0.9, rubber Glue burr loss more than 30%, expends rubber-sole and beats the process of bottom liquid medicine and glue, consumption in the process of thick and liquid medicine and glue and EVA Take rubber to fit with middle bottom expense etc..By cost calculation, compare with the traditional process mode of production, using rubber bound of the present invention In the rubber soles production technology of agent, rubber and EVA bottoms at least less manpower and manufacturing expense 20% that a pair of is combined.Equivalent to Every pair of finished product EVA shoe coxopodite saves $ 0.4 ~ 0.6.
