Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
The preparation method of a kind of shoe pad, comprises the following steps:
1) ETPU granule average mark is dispersed on shoe pad tool; Quantitative ETPU granule is poured on shoe pad tool, and by staff or machine, ETPU granule is uniformly distributed, be substantially and keep ETPU granule not have the situation of overlap to occur, so can ensure quality;
2) will simultaneously have sticking thin slice (this thin slice the present embodiment uses non-woven fabrics) at least within and be laid on the shoe pad tool being covered with ETPU granule, and make ETPU granule on average be pasted onto on this thin slice, form semi-finished product; On ETPU granule all adhesive band thin slices, related for thin slice ETPU granule can be easily transferred to subsequent processing;
3) these semi-finished product are placed in shoe pad mould, and irrigate shoe pad injection raw material, then compressing again; This shoe pad injection raw material is generally adopted PU material, and concrete production can be replaced as required;
4) through post processing, finished product is made; The operation of post processing is deburring etc.
Wherein, also needed to be punched out described thin slice before described step 1), make described thin slice is evenly distributed with through hole. The size of punching determines according to the size of footwear and the size of ETPU granule. In principle still. This through hole can when perfusion injection raw material, enable injection raw material to be penetrated in the ETPU granule of thin slice bottom surface by through hole, and rapidly, uniformly, be fully filled between ETPU granule and ETPU granule, finally by seamless for ETPU granule parcel, reach the effect of the best.
Wherein, in described step 1), it is dispersed in the diverse location on shoe pad tool according to the size of ETPU granule, with the diverse location of corresponding shoe pad. Wherein, quantitative little ETPU granule is placed on shoe pad tool and is positioned at the arch of the foot position to sole, quantitative big ETPU granule is placed on shoe pad tool and is positioned at the arch of the foot position to heel. Owing to the thickness of shoe pad changes according to the position difference of sole to arch of the foot to heel, in general, the thickness of heel is thicker than the thickness of sole, so in order to make that buffering effect is all even to be given full play to, arranging the ETPU granule for size according to shoe pad different-thickness.
