Description
Technical field
The present invention relates to footwear material field, relate in particular to a kind of ultra-soft degree glue for sole and preparation method thereof.
Background technology
Sole is the important part in footwear material field, and the major function of sole is to protect foot, and is anti-skidding, and damping guarantees the comfortable of user's foot, reduces the occurrence probability of sport injury.
The material of sole is in the majority with rubber-sole at present.At the bottom of General Purpose Rubber, thermoplastic shaping, minute natural rubber and regenerated rubber.Although wear resistance is good, anti-skidding, flexible, easy fracture not, pliability is better, expandability good, contraction is stable, hardness is good, good bandability, waterproof.The comfort level of sole depends on elasticity and the snappiness of sole, yet present sole elasticity and snappiness are not enough, is difficult to satisfy the demand of high standard.
Summary of the invention
Based on this, be necessary the problem for existing sole elasticity and snappiness deficiency, thereby provide a kind of elasticity and snappiness that can effectively increase sole to increase to a greater extent the ultra-soft degree glue of dressing comfortableness.
A kind of ultra-soft degree glue for sole is made by the raw material of following weight part: natural rubber 40-50 part, synthetic rubber 40-50 part, white carbon black 20-30 part, naphthenic oil 6-7 part, sulphur 1.5-2.5 part, vulcanization leveller 4-5 part, vulcanization accelerator 1.8-2.5 part, zinc oxide 4-6 part, stearic acid 0.8-1 part, antifogging agent 0.3-0.8 part, anti-aging agent 1.5-2 part.
Natural rubber is 3L mark glue and IR glue.
Synthetic rubber is cis-butadiene cement.
A kind of preparation method of the ultra-soft degree glue for sole comprises the steps: step 1, and the natural rubber of 40-50 weight part at the Banbury mixer acquisition broken-(down)rubber of plasticating, is deposited after one day and cut glue; Step 2 on the basis of step 1, adds the synthetic rubber of 40-50 weight part successively, the white carbon black of 20-30 weight part, and the vulcanization leveller of 4-5 weight part carries out banburying, and the time is 2-3 minute; Step 3: on the basis of step 2, add the zinc oxide of 4-6 weight part, the stearic acid of 0.8-1 weight part, the naphthenic oil of 6-7 weight part, the antifogging agent of 0.3-0.8 weight part, the mixing 6-8 of the anti-aging agent of 1.5-2 weight part minute, the cooling of upper roller slice, and park more than half a day; Step 4 on the basis of step 3, adds the sulphur of 1.5-2.5 weight part, and the vulcanization accelerator of 1.8-2.5 weight part, and at 145-160 ℃, pressure are sulfuration 5-7 minute under the condition of 12-20mpa, namely obtain described a kind of ultra-soft degree glue for sole.
Natural rubber is 3L mark glue and IR glue.
Synthetic rubber is cis-butadiene cement.
The ultra-soft degree glue that should be used for sole, scientific formulation, cost is low, and preparation technology is simple, has strengthened elasticity and the snappiness of sole, the comfort level of can Effective Raise dressing.
Embodiment
The present invention will be further described below in conjunction with specific embodiment.
Synthetic rubber adopts cis-butadiene cement, and the winter hardiness of the cis-1,4-polybutadiene rubber after the sulfuration, wear resistance and elasticity is excellence especially, and heating is lacked under the dynamic load, and ageing resistance is fair, easy and natural rubber, chloroprene rubber or butyronitrile rubber and usefulness; Cis-1,4-polybutadiene rubber intermolecular forces is little, and molecular weight is high, thereby Chain Flexibility is large, and second-order transition temperature is low, is amorphous state when normal temperature is zero load, and very high deformability is arranged when bearing external force, is the best synthetic rubber of elasticity and winter hardiness.And because molecular chain is more regular, can obtain the crystallization reinforcement during stretching, add the black-reinforced effect that carbon black can obtain showing again, over-all properties is good.
The effect of white carbon black is as stopping composition on the one hand, and it can improve wear resistance and the anti-slippery of rubber simultaneously, and uses the sizing material tensile strength, tear strength, wear resistance etc. of white carbon black to be improved.
Naphthenic oil has the saturated cyclic carbon-chain structure, has low pour point, high-density, high viscosity, the characteristics such as have no side effect, and on its ring, usually also can connect saturated side chain.Because this structure makes naphthenic oil have the strong character of stability, the wear resistance of sole is had very great help.
When zinc oxide is applied in the rubber, should select the special-purpose zinc oxide of rubber, mainly as natural rubber, elastomeric activator.Its particle is tiny to be spherical, has very large surface-area, have good dispersiveness and good adsorptivity, thereby can promote rubber sulfuration, activation and reinforcement anti-aging effect, can strengthen sulfidation, reach stability, processing safety raising, decrease fraction defective, 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, and the vulcanization leveller of widespread use in synthetic rubber and the latex also can be used as softening agent and tenderizer.Need add stearic acid and make emulsifying agent in producing the synthetic rubber process, when making spongy rubber, stearic acid can be made pore forming material, and stearic acid also can be used as the releasing agent of rubber item.The industry stearic acid is widely used in makeup processed, plastics cold resistant plasticizer, releasing agent, stablizer, tensio-active agent, thiofide, promoting agent.
Under a kind of embodiment, prepare the material of following weight part: natural rubber 40-50 part, synthetic rubber 40-50 part, white carbon black 20-30 part, naphthenic oil 6-7 part, sulphur 1.5-2.5 part, vulcanization leveller 4-5 part, vulcanization accelerator 1.8-2.5 part, zinc oxide 4-6 part, stearic acid 0.8-1 part, antifogging agent 0.3-0.8 part, anti-aging agent 1.5-2 part.
Wherein, natural rubber is 3L mark glue and IR glue; Synthetic rubber is cis-butadiene cement.
Concrete preparation process is as follows:
Step 1 at the Banbury mixer acquisition broken-(down)rubber of plasticating, is deposited the natural rubber of 40-50 weight part after one day and is cut glue;
Step 2 on the basis of step 1, adds the synthetic rubber of 40-50 weight part successively, the white carbon black of 20-30 weight part, and the vulcanization leveller of 4-5 weight part carries out banburying, and the time is 2-3 minute;
Step 3: on the basis of step 2, add the zinc oxide of 4-6 weight part, the stearic acid of 0.8-1 weight part, the naphthenic oil of 6-7 weight part, the antifogging agent of 0.3-0.8 weight part, the mixing 6-8 of the anti-aging agent of 1.5-2 weight part minute, the cooling of upper roller slice, and park more than half a day;
Step 4 on the basis of step 3, adds the sulphur of 1.5-2.5 weight part, and the vulcanization accelerator of 1.8-2.5 weight part, and at 145-160 ℃, pressure are sulfuration 5-7 minute under the condition of 12-20mpa, namely obtain described a kind of ultra-soft degree glue for sole.
Just made a kind of ultra-soft degree glue for sole by above material and step, this ultra-soft degree glue scientific formulation for sole, cost is low, preparation technology is simple, has strengthened elasticity and the snappiness of sole, Effective Raise the comfort level of dressing.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
