Two hardness soles and preparation method thereof
Technical field
The present invention relates to a kind of making method of sole, specifically, is the making method of two hardness soles, belongs to the footwear technical field.
Technical background
The sole making method of existing two kinds of hardness combinations mainly is that low-durometer material is adopted at the half sole position in the prior art, and high hardness material production is adopted at the whole position of heel (after the pin loin).But the shortcoming of using this technology is that the resistance to oxidation effect of bi-material is different, causes two kinds of hardness combining sites that obvious vestige (rubber look, transparent color more obvious) is arranged, and the bi-material binding site has the risk at the disconnected end that disconnects simultaneously; Because high rigidity spring heel density (proportion) is large, sole is heavy in addition.
Summary of the invention
For the problems referred to above, the present invention discloses two kinds of hardness joint marks of a kind of effective solution problem, effectively avoids the fracture of the disconnected end simultaneously, two hardness soles comfortable and easy to wear and preparation method thereof.
Last technical scheme of the present invention is: this pair hardness sole, half sole and heel peripheral portion adopt low-durometer material to make, and the keel position adopts the high rigidity light material to make in the middle of the heel.
Further, above-mentioned two hardness soles, described low-durometer material comprises the component of following mass parts: cis-1,4-polybutadiene rubber, 24-26 part; Natural rubber SVR-3L5.5-6.5 part; Styrene-butadiene rubber(SBR) 11-13 part; White carbon black 14-16; White carbon black promoting agent DEG7.5-8.5 part; PEG-40005.5-6.5 part; Stearic acid 3.5-4.5 part; Zinc carbonate 2.0-2.4 part; Antideteriorant BHT 1.8-2.2 part; Microcrystalline Wax 1.8-2.2 part; Rubber prevents telling creme 3.8-4.2 part; Altax 5.5-6.5 part.
Further, above-mentioned two hardness soles, described high hardness material comprises the component of following mass parts: cis-1,4-polybutadiene rubber 8-10 part; Natural rubber SVR-3L8-9 part; Styrene-butadiene rubber(SBR) 1.8-2.2 part; High-phenylethylene 24-26 part; White carbon black 13-14 part; 1.5 parts of naphthenic oils; White carbon black promoting agent DEG, 6.5-7.5; PEG-40003.5-4.5 part; Stearic acid 4-5 part; Zinc carbonate 1.8-2.2 part; Antioxidant SP-P4.5-5 part; Altax-802.5-3.5 part.
Further, above-mentioned two hardness soles, the durometer level of described high hardness material is at 70-100 ° of shore A.
Further, above-mentioned two hardness soles, the durometer level of described low-durometer material is at 40-70 ° of shore A.
A technical scheme is after of the present invention: the making method at the bottom of this pair hardness sole shoes comprises the steps: 1 successively) by following mass parts, take by weighing each component, cis-1,4-polybutadiene rubber 24-26 part; Natural rubber SVR-3L5.5-6.5 part; Styrene-butadiene rubber(SBR) 11-13 part; White carbon black 14-16; White carbon black agent DEG7.5-8.5 alive part; PEG-40005.5-6.5 part; Stearic acid 3.5-4.5 part; Zinc carbonate 2.0-2.4 part; Antideteriorant BHT 1.8-2.2 part; Microcrystalline Wax 1.8-2.2 part; Rubber prevents telling creme 3.8-4.2 part; Altax powder 5.5-6.5 part, method for preparing rubber prepares respectively low-durometer material routinely; Take by weighing again: cis-1,4-polybutadiene rubber 8-10 part; Natural rubber SVR-3L 8-9 part; Styrene-butadiene rubber(SBR) 1.8-2.2 part; High-phenylethylene 24-26 part; White carbon black 13-14 part; 1.5 parts of naphthenic oils; White carbon black promoting agent DEG 6.5-7.5 part; PEG-4000 3.5-4.5 part; Stearic acid 4-5 part; Zinc carbonate 1.8-2.2 part; Antioxidant SP-P4.5-5 part; Altax-80,2.5-3.5 part, preparation low-durometer material;
2) at the low-durometer material cutting sole basic unit that step 1) prepares, cutting spring heel keel on the high hardness material;
3) matched moulds production sulfuration, first sole basic unit is positioned over mold bottom, again spring heel is positioned over the peripheral place of spring heel, again keel are embedded in the mould top cover die keel, guarantee that concavo-convex position and the concavo-convex position of mould of expecting are consistent, matched moulds sulfuration between 160-170 ℃.
Further, the making method at the bottom of above-mentioned two hardness sole shoes, described keel comprise the first keel and the second keel.
High hardness material of the present invention has the characteristics of lightweight, has guaranteed that spring heel density is little, and sole is light, and is comfortable and easy to wear.
