Description
Technical field
The present invention relates to a kind of rubber soles and preparation method thereof, be specifically related to a kind of wear-resisting high-elastic microvesicle rubber soles and preparation method thereof.
Background technology
At present, along with developing rapidly of economy, people to the dress of leather shoes to solid, wear-resisting gradually to the different demand angle development and change such as light, comfortable and attractive in appearance, especially, along with the lifting of leisure demand, lightweight formed sole product is more and more subject to people's favor. But at the bottom of shaping foam, product all can only carry out stamping-out and edging, dress along rear processing processing such as bars after sulfur foam at present, and cannot make footwear the same as General Purpose Rubber formed sole limit upper of a shoe straight forming, after being mainly foaming sulfuration die sinking, foamed shoe sole can expand and become large, size is unstable, and shoe sole print is unintelligible, the inaccurate meeting of expansion ratio control cause size too little can not with or the excessive stamping-out of size after decorative pattern to not going up, the sulfurizing mould that will use special setting contracting ratio when production, has expanded production cost.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of wear-resisting high-elastic microvesicle rubber soles and preparation method thereof, and preparation method is simple, the bubble rubber soles lightweight good springiness of making, and decorative pattern definition, finished size and die cavity shape are reached 1: 1 ratio.
The technical scheme that technical solution problem of the present invention adopts is: a kind of wear-resisting high-elastic microvesicle rubber soles, the rubber raw materials that is 62～65% by mass percent, 16～18% EVA resin, 8% reinforcing agent, 1.7% activating agent, 5% plasticizer, 1% antiflatulent, 1～2% blowing agent, 1% crosslinking agent and 0.5～2% colouring agent form, and styrene butadiene rubber sbr that described rubber raw materials is 10%-28% by percentage by weight 1502,42%～70% natural gum, cis-1 and 15%～35% 4-polybutadiene rubber (cis-butadiene cement) form.
Preferred as one, in described EVA resin, the content of vinyl acetate is 18%; Described reinforcing agent is white carbon; Described activating agent is zinc oxide and stearic acid, and described zinc oxide and stearic acid weight ratio are 1: 0.7～0.8; Described plasticizer is rubber naphthenic oil; Described antiflatulent is the antiflatulent FC-617 that flows; Described blowing agent is physical blowing agent; Described physical blowing agent is a kind of small spherical plastic grain, and its maximum blowing temperature is 161～171 DEG C; Described crosslinking agent is tasteless DCP(cumyl peroxide); Described colouring agent is organic pigment coloring agent.
A preparation method for wear-resisting high-elastic microvesicle rubber soles as above, comprises the steps:
(1) determine base material factory formula.
(2) first natural gum is carried out to banbury and plasticate 10～15 minutes, place 4～6 hours;
(3) by above-mentioned natural gum and butadiene-styrene rubber, cis-butadiene cement, EVA resin, reinforcing agent, activating agent, plasticizer and antiflatulent proportioning by weight, adopt mixer mixing, by technique mixing 15 minutes, temperature reached 135 ± 5 DEG C, by the mill slice that turns refining, cooling rear for subsequent use after binder removal;
(4) by the elastomeric compound preparing, turn refining with mill, control temperature below 110 DEG C, then add crosslinking agent and blowing agent to turn refining to mix, adopt indirect type of cooling slice, and cooling for subsequent use, base-material slice THICKNESS CONTROL is at 0.2mm;
(5) select forming vulcanization die, take this elastomeric compound and only add crosslinking agent and do not add blowing agent, after sulfidization molding, claim its weight, then reduce 17% established standards weight in foaming ratio;
(6) weigh up base-material by standard weights, put into and be confined to the sulfuration of mould molding sulfuration machine, sulfuration design temperature is 172 DEG C, and the time is 15～20 minutes, and it is cooling that cure time finishes rear taking-up deburring.
The invention has the beneficial effects as follows: selected specific physical blowing agent Sweden EXPANCEL model 091DU40, while making product be heated to 120 DEG C in die cavity, expand rapidly, base material is strutted and is full of die cavity, temperature reaches the blowing temperature of blowing agent maximum while being raised to 170 DEG C, the crosslinking rate of tasteless DCP is more smooth, producing base material expansion while being cross-linked completes, after sulfuration finishes molding, product can not reexpand, finished size and die cavity shape are reached 1: 1 same ratio, product decorative pattern shoe last or hat block type can not change, owing to being still closed spheroid after blowing agent foaming, size is less than 50 μ m and stabilized structure has very strong resistance to pressure, can not produce to shrink and there is good elasticity and wearability, improve the wear resistance decrease that conventional foamed products causes due to the impact of material mesopore bubble existence, this product can reach the wearability of conventional formed sole product. product has been broken through the limitation of rubber pange to decorative pattern variety production, and the pattern effect of existing common formed sole has again the lightweight of foaming bottom, and kind is horn of plenty more, and product density can be controlled in 0.7g/cm3～0.85g/cm3, the mould inventory of phase homomorphs reduces 17～20% on year-on-year basis, reduces the use of material, and can use the mould of normal size to produce, and without another system contracting, than mould, lifting economic benefit reduces production costs.
