Description
Technical field
The present invention relates to macromolecular material manufacturing technology field, specifically a kind of elastic composite sole and preparation method thereof.
Background technology
We know that traditional leather shoes sole generally adopts polyolefin plastics to make, and also has at the bottom of rubber soles and the polyurethane shoe.Polyolefin plastics elasticity is better, but wearability is relatively poor; The rubber soles quality is comparatively closely knit, and wearability is better, but poor flexibility, and weight is bigger.Present most of leather shoes sole is all made by homogenous material, and the functional and properties of product of footwear material have many deficiencies.
Summary of the invention in recent years, various functional shoe are also come out one after another on the market, and people are for the size that makes footwear and pin is fit to, and have designed and changed group footwear, sole changeable shoes, changed with footwear respectively etc., the shoe tree type of field replaceable unit and set-back must be abided by and be sought certain rules, to the designing requirement height.
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of rational in infrastructure, dependable performance is provided, and processing cost is low, good springiness, but sole transversal stretching, elastic composite sole comfortable and easy to wear and preparation method thereof.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of elastic composite sole, it is characterized in that: it makes substrate with the General Purpose Rubber material, be provided with the excipient hole in the middle of the substrate, the excipient hole is provided with the telescopic elastic rubber strip, and elastic rubber strip and substrate are compound to be one, and the component of described elastic rubber strip is: natural gum 70-85%, white carbon 7-15%, ring oil firing 5-10%, promoter and activating agent 2-5%, age resister 1-2%.
The above-mentioned elastic composite preparation of soles of the present invention method, it is characterized in that adopting following steps: after the first, base material prepares by component, joining banbury carries out mixing, monitor by the rubber process monitor, mixing time is 5-10 minute, 110 ℃～130 ℃ of temperature, slice, cooling stack; The second, after elastic rubber strip prepares by component, join banbury and carry out mixingly, mixing time is 5-10 minute, 110 ℃～130 ℃ of temperature, and slice, cooling stack; Three, above-mentioned elastic sheet rubber is put into the middle bar groove of mould that designs and vulcanized, curing temperature is 160 ± 2 ℃, and cure time is 5-10 minute, the clout that the elastic rubber strip both sides after cleaning then, the stamping-out sulfuration have more; Four, the substrate rubbers sheet is put into the mould and the elastic rubber strip that design again and vulcanized together, the rubber composition is fused mutually be bonded to one, curing temperature is 160 ± 2 ℃, and cure time is 5 minutes and 30 seconds; Five, slice, stamping-out are made the elastic composite sole.
The present invention firmly is combined into one two kinds of different rubber material layers, and against existing technologies, the present invention makes sole integral body have wearability and better elasticity concurrently, particularly the elastic rubber strip in the middle of the substrate excipient hole has better elasticity, and is scalable, stressed changeable type expansion, laterally the maximal dilation amount can reach 5mm, give the function of modification, reach the purpose of fitting, applicability is strong, and has a higher-strength, wear is comfortable, and day is difficult for into splitting or ftractureing long afterwards, increases the service life.Its rational in infrastructure, dependable performance improves the elasticity and the applicability of sole greatly, and is applied widely.
