Abstract
The invention discloses a new process capable of increasing the bonding strengths of uppers and soles of injected or mould-pressed shoes. The core of the method is that 1-2 lines are additionally stitched at the bonding parts of the roughed and adhesive-brushed uppers and soles, and adhesive tapes are stitched at specified positions of upper feet; in the method, an adhesive is a vulcanized adhesive, the used adhesive tapes are primer materials, the stitch lines are adhesive-dipped cotton lines, and matched temperature, time and pressure need to be controlled during injection (or mould pressing); the bonding strengths of the products produced by virtue of a normal injection process are as follows: the bonding strengths of left feet are 3.708N/cm, and the bonding strengths of right feet are 2.194N/cm, whereas the bonding strengths of the products produced by virtue of the process are as follows: the bonding strengths of left feet are 4.451N/cm, the bonding strengths of right feet are 8.399N/cm, and the bonding strengths are higher than a standard value of 4.0N/cm.
Description
Technical field
The invention belongs to shoe-making field, relate in particular to a kind of technique increasing bonding strength at the bottom of injection or mold pressing upper of a shoe.
Background technology
For mold pressing (injection) leather shoes (boots) of specific function, require to be bonded in the process of wearing at the bottom of the side of product to should bear more powerful external force.Footwear or the boots bonding strength standard value of this specific function are 4.0N/cm.Normal injection or mould pressing process method make next footwear or boots, and its bonding strength is: left foot 3.708N/cm, and right crus of diaphragm 2.194N/cm, all lower than standard value.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of a kind of new technology increasing bonding strength at the bottom of injection or mold pressing upper of a shoe, the core of this kind of method is that bond site at the bottom of the side of fluffing, brush coating is added seam 1 ~ 2 diatom, adhesive tape is sewn on the assigned position of side pin; The adhesive vulcanization type adhesive of this kind of method, adhesive tape used is bottom sizing, and suture is impregnation cotton thread, during note pressure (or mold pressing), should control the temperature of coupling, time, pressure.
Object of the present invention is achieved through the following technical solutions:
Increase a kind of new technology of bonding strength at the bottom of injection or mold pressing upper of a shoe, comprise the following steps:
A helps pin impression: be enclosed within iron pin on request, and lower iron pin closes limit and touches, and rectifies and extrudes impression;
B helps pin fluffing: evenly fluff, the degree of depth is the 1/4-1/3 of leather thicknesses;
C brush coating, oven dry: even brush coating on request, and enter oven for drying: temperature 50 ~ 60 DEG C, 5 ~ 8 minutes time;
D viscose top: help pin border viscose top on request;
E side seam line: on request to adhesive tape position suture, makes side pin and adhesive tape fixation;
F note pressure, mold pressing: time: 12 ~ 15 minutes, temperature 155 ~ 160 DEG C, pressure 70 ~ 150 ㎏;
G depanning, draw glue: depanning after mold pressing, and draw glue, clear limit on request.
A kind of new technology of bonding strength at the bottom of above-mentioned increase injection or mold pressing upper of a shoe, step e side seam line: on request to suture 1 ~ 2 road, adhesive tape position, two lines are all apart from adhesive tape edge 3 ~ 4 ㎜.
A kind of new technology of bonding strength at the bottom of above-mentioned increase injection or mold pressing upper of a shoe, in step e side seam line, suture is impregnation cotton thread.
A kind of new technology of bonding strength at the bottom of above-mentioned increase injection or mold pressing upper of a shoe, with vulcanization type adhesive viscose top in steps d viscose top.
Adopt technique scheme, the present invention has following advantage: the maximum feature of the present invention is that first adhesive tape is connected by suture, adhesive with helping pin, shaping by injection (or mold pressing) again, reach the mixed-forming of upper of a shoe and outer bottom sizing, suture wherein plays the effect that " reinforcing bar " is reinforced, and greatly can improve the bonding strength at the side end.Its bonding strength of product of normal note compression technology is: left foot 3.708N/cm, right crus of diaphragm 2.194N/cm, and takes the product of this kind of technique, and bonding strength is: left foot 4.451N/cm, right crus of diaphragm 8.399N/cm, higher than standard value 4.0N/cm.
Detailed description of the invention
Increase an a kind of new technology for bonding strength at the bottom of injection or mold pressing upper of a shoe, comprise the following steps:
A helps pin impression: be enclosed within iron pin on request, and lower iron pin closes limit and touches, and rectifies and extrudes impression;
B helps pin fluffing: evenly fluff, the degree of depth is the 1/4-1/3 of leather thicknesses;
C brush coating, oven dry: even brush coating on request, and enter oven for drying: temperature 50 ~ 60 DEG C, 5 ~ 8 minutes time;
D viscose top: help pin border vulcanization type adhesive viscose top on request;
E side seam line: on request to suture 1 ~ 2 road, adhesive tape position, two lines, all apart from adhesive tape edge 3 ~ 4 ㎜, make side pin and adhesive tape fixation, and in suture, suture is impregnation cotton thread;
F note pressure, mold pressing: time: 12 ~ 15 minutes, temperature 155 ~ 160 DEG C, pressure 70 ~ 150 ㎏;
G depanning, draw glue: depanning after mold pressing, and draw glue, clear limit on request.
