Embodiment
Embodiment
Natural rubber is 3L mark glue.Based on rubber hydrocarbon (polyisoprene), contain a small amount of protein, moisture, resinous acid, carbohydrate and inorganic salt etc.Elasticity is big, the tensile modulus height, and tear strength and electrical insulating property are good, and wear resistance and drought tolerance are good, and processibility is good, and it is bonding to be easy to other material, is better than most synthetic rubber aspect over-all properties.Shortcoming is that oxytolerant and ozone resistance are poor, aged deterioration easily; Oil resistant and solvent resistance are bad, and the corrosive power of antiacid alkali is low; Thermotolerance is not high.
Synthetic rubber is cis-1,4-polybutadiene rubber.The performance of cis-1,4-polybutadiene rubber is because the molecular structure of cis-1,4-polybutadiene rubber mainly is cis 1, the 4-structure, and molecular arrangement is regular, so its elasticity is better than natural rubber.The elasticity of cis-1,4-polybutadiene rubber is best a kind of in the conventional rubber.Thermotolerance is identical with natural rubber, but heat aging property is better than natural rubber.Tensile strength is all lower than natural rubber, styrene-butadiene rubber(SBR), therefore must add strengthening agents such as white carbon black.The excellent in abrasion resistance of cis-1,4-polybutadiene rubber, hysteresis loss is little, and living heat is low, and the tension set performance is good.
SEBS glue is styrene block copolymer.Because SEBS does not contain unsaturated double-bond and purity is higher, at this and following two kinds of advantages are arranged: (1) antioxygen, ozone resistants are better; (2) contain protein in the natural rubber, can make some patient produce dangerous anaphylaxis, and this blend just can not.
Synthetic EVA is the ethylene-vinyl acetate copolymer after foaming.In the EVA resin that the footwear material uses, vinyl acetate content is generally 15%～22%.Because EVA resin alloy foaming product has performances such as softness, good springiness, resistance to chemical attack, therefore be widely used in the sole and interior material of medium-to-high grade sneakers, climbing boot, slippers, sandals.
White carbon black is as filler, and it can improve wear resistance and the anti-slippery of rubber, and uses the sizing material tensile strength, tear strength, wear resistance etc. of white carbon black to be improved.
Naphthenic oil has saturated and the ring-type carbon-chain structure.And naphthenic oil has aromatic hydrocarbon sector of breakdown character, has the part character of straight chain hydrocarbon again, because naphthenic oil from natural oil, has advantages such as cheap, from the horse's mouth.
When high-active zinc oxide was applied in the rubber, the high-active zinc oxide of rubber special use was mainly as natural rubber, elastomeric activator.Its particle is tiny to be spherical, has very big surface-area, have good dispersiveness and good adsorption, thereby can promote rubber sulfuration, activation and reinforcement anti-aging effect, can strengthen sulfidation, reach stability, processing safety raising, reduce fraction defective significantly, improve rubber item resistance to tearing, wear resistance.Simultaneously, can improve anti-aging, the anti-crawl agentdefiection fragility energy of rubber product.
Other stearic acid of rubber grade is emulsifying agent in the synthetic and course of processing of rubber.Stearic acid plays an important role in the synthetic and course of processing of rubber.Stearic acid is natural gum, elastomeric vulcanization leveller, also can be used as softening agent and tenderizer.Need add stearic acid and make emulsifying agent in producing the synthetic rubber process, stearic acid also can be used as the releasing agent, vulcanization leveller, tenderizer of rubber item etc.
Embodiment is following with materials in weight portion: natural rubber: 40-60 part, synthetic rubber: 30-40 part, SEBS glue: 10-20 part, synthetic EVA:10-20 part, ultralight white carbon black: 30-40 part, naphthenic oil: 6-10 part, high-active zinc oxide: 3-5 part, promoting agent: 3-5 part, vulcanization accelerator: 2-3 part, stearic acid: 1-2 part, glycol ether: 2-3 part, anti-aging agent: 1-3 part.Wherein, natural rubber is 3L mark glue: synthetic rubber is cis-butadiene cement and artificial natural gum IR; SEBS glue is styrene block copolymer, and synthetic EVA is the ethylene-vinyl acetate copolymer after foaming, and super white carbon black is the strong super white cigarette of elasticity.
Step 1: with the 40-60 parts by weight of natural rubber at the Banbury mixer acquisition broken-(down)rubber of plasticating;
Step 2: on the basis of step 1, add the synthetic rubber of 30-40 weight part successively, 10-20 weight part SEBS glue, the 10-20 weight part synthesizes EVA, the super white carbon black of 30-40 weight part, the promoting agent of 3-5 weight part carries out banburying, and the time is 6 minutes;
Step 3: on the basis of step 2, add the high-active zinc oxide of 3-6 weight part, the stearic acid of 1-2 weight part, the anti-aging agent of 1-3 weight part, 2-3 weight part glycol ether, mixing 7 minutes of the naphthenic oil of 6-10 weight part;
Step 4: on the basis of step 3, the vulcanization accelerator of 2-3 weight part, and at 150-160 ℃, pressure are sulfuration 5-8 minute under the condition of 11-18mpa.
In addition, can also be behind slice 18-24h, will expect to carry out again mixing, specifically can followingly operate: weighing 40kg, mixing plate in the mill is put into the 5-6 millimeter, mixing 3 minutes, again plate is got to 3 millimeters, plasticate.Survey its sulphur and become, time T S1.25 minute, TC90:2.4 minute.In the vulcanizer directly sulfidization molding become sole.Just made a kind of ultralight snappiness glue for sole by above material and step, this ultralight snappiness glue that is used for sole has improved the anti-bending degree of sole greatly, make sole have longer life, and elasticity is splendid, can fully guarantee the comfortable of wearer, sense lessens fatigue.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
