Description

Rubber soles material of a kind of no marking and preparation method thereof

Technical field

The present invention relates to rubber soles material of a kind of no marking and preparation method thereof.

Background technology

Manufacture sole, generally speaking Rubber processing, sulfurization technology are meant that all with rubber such as butylbenzene, suitable fourth and tree elastomer be base mateiral, and add multiple auxiliary agent; Synergist S-421 95 etc.; Adopt under the different technological conditions through various processing equipment, make rubber and various processing aid, filler and vulcanization system etc. mix (rubber unvulcanizate; Cross-linked rubber) and with auxilliary joining of multiple framework material (high molecular polymer) combine, processing is sulfided into the rubber item of typing; Because of judging through research, black cut is from rubber and the carbon black mixing process, and carbon black can't be scattered in the rubber fully, and existing material for sole of shoe very easily causes the cut of rubber soles in the process of preparation.

Summary of the invention

To defective that exists in the prior art and deficiency, the present invention provides a kind of no marking rubber soles material and this preparation methods thereof.

SBR styrene-butadiene rubber(SBR), NR tree elastomer and the BR cis-1,4-polybutadiene rubber matrix plinth material of making a living in the said above-mentioned materials; Carbon black (N330HAF high wearable) is the filler reinforcement system; NO 4010, Triple Pressed Stearic Acid and Microcrystalline Wax (paraffin) are the process operation auxiliary agent; Oleic acid (epoxidation) is the softening finish of plasticising; Antioxidant 1010, antiozonidate Ursol D are protection system; Sulphur S8, M (MBT), DM (MBTS), PEG-4000 polyoxyethylene glycol promote activation system for sulfuration.

The invention allows for a kind of no marking rubber soles preparation methods simultaneously, comprising:

Step 1, rubber is dropped into the mill mastication, smooth up to having an even surface;

Step 2, mastication glue (broken-(down)rubber) is dropped in the Banbury mixer, add Triple Pressed Stearic Acid;

Step 3, with the carbon black input, operated 15 minutes, 95 ± 2 ℃ of controlled temperature in case of necessity, are opened cooling water valve;

Step 4, after other Synergist S-421 95 additives are dropped into (remove sulphur M, DM, ENO is outer);

Step 5, more than be called unvulcanized glue stuff compounding, take out quiet put overnight;

Step 6, weigh quantitative rubber unvulcanizate and do the mill platform, add quantitative sulphur M, the DMT zinc white;

Step 7, above-mentioned sizing material is rolled the typing of plate in blocks or die;

Step 8, in the sulfuration board on, the sulfuration finished product (sole).

Material for sole of shoe of the present invention is compared with other material for sole of shoe, has characteristics such as anti-wear-resisting, anti-cut and production process are simple.

Rubber soles is manufactured employed base mateiral and is all rubber (styrene-butadiene rubber(SBR); Cis-1,4-polybutadiene rubber, tree elastomer) use that a large amount of filling--strengthening agent carbon black (30-40%) carbon black can reduce the elasticity of sizing material, the level that the preferential absorption molecular weight is big is divided; What remaining molecular weight was less helps relaxing for free rubber (or being called occlusion rubber); Reduce the expansion shrinking percentage, use mixer mixing usually, carbon black particle is obtained in rubber in the good moistening and dispersion milling; Because belonging to aniseed (broken-(down)rubber adds 50-60 part carbon black for 100 parts approximately), carbon black must observe the order that feeds intake, one, whole broken-(down)rubbers (rubber is first at the mill mastication); Two, a spot of solid softener (like Triple Pressed Stearic Acid) drops into earlier; Three, carbon black is dropped in the back.

Mixing initial stage particle diameter is very little and carbon black particle that specific surface area is very big relies on it and the compatibility of rubber and the surfactivity of tenderizer; At first moistening by rubber, rubber penetrates into the carbon black that forms high density in the space of carbon black aggregate subsequently--and this is the moistening stage of rubber unvulcanizate rubber group.

The mixing later stage: carbon black--rubber group overcomes the force of cohesion that gathers micelle by powerful shearing force, and carbon black is finely dispersed in the broken-(down)rubber equably.The dispersion size of carbon black aggregate in glue stuff compounding also receives the influence that rubber is met thermogenetic viscoelastic viscosity and velocity of shear size except shearing force, its requirement is that 90% above carbon black agglomerate size is below 5nm.This is bound rubber for (micron order).
