Making this is the high-molecular coating glue of main ingredient with the ethylene-vinyl acetate copolymer, and its method is as follows:
Earlier raw material is dropped into the reactor from batching hole by the above proportioning that provides and fully stir, reactor progressively is warming up to 180 ℃～200 ℃ again, Deng fully the fusing after, opening bleeder valve will expect slowly to be released in the shaping dish, through the cooling tank cooling, by dicer glue is cut into the blob of viscose of suitable size then.
Below be embodiment:
Embodiment 1: raw material is prepared by prescription 1, drop in the reactor and fully stir, simultaneously reactor progressively is warming up to 180 ℃, and keep this temperature, and to treat to open bleeder valve after material melts fully, discharging is to the shaping dish, through the cooling tank cooling, through dicer glue is cut into the blob of viscose of suitable size again.
Embodiment 2: raw material 4 is prepared by prescription, drop in the reactor and fully stir, simultaneously the temperature of reactor is risen to gradually 190 ℃ and keep this temperature, wait to expect to melt fully back discharging, cooling, stripping and slicing to the suitable blob of viscose of specification.Present embodiment has best effect.
Embodiment 3: prepare raw material by prescription 5 and drop into reactor, fully stir, simultaneously the still temperature is progressively risen to 200 ℃, and keep this temperature to treat material fusing fully, discharging then, cooling, stripping and slicing.
The purposes of this thermally melting high-molecular coating glue, be to make master that a kind of leather shoes use with and the packet header material.This material is high-molecular coating glue (bulk) to be given add fusing in hot glue groove (4), (5), make through giving the yarn fabric of processing or base material (10) that non-woven fabrics is the base skeleton and at the uniform velocity add running roller (2), (3) upper surface in hot glue groove (4), (5) by immersion, thermally melting coating glue in the groove is coated on by running roller (2), (3) on the base material (10) that slowly passes through, and the thickness of coating glue-line and smooth uniformity coefficient are by placing running roller (2), (3) both sides, making with scraper (6), (7) of running roller axially parallel.Yarn fabric or non-woven fabrics can single spreading also can double spread.
The temperature that adds hot glue groove (4), (5) remains on 180 ℃～200 ℃, and the temperature of scraper (6), (7) remains on 150 ℃～160 ℃.
Adopt this high-molecular coating glue make footwear with mainly follow, the packet header material has thermoplasticity, not only will simplify the leather shoes production technique greatly, improve mechanization degree and production efficiency that shoemaking is produced, reduce cost, alleviate labor strength, eliminate the harm of toxic gas, and because the proportion of material is little, good springiness, strong, the good stability of toughness, can strengthen the sense comfortable and easy to wear of leather shoes greatly, improve the stability of leather shoes moulding.
