Background technology
EPDM and ethylene propylene diene rubber, belong to polyolefin family, thus have fabulous cure, and in the middle of all rubber, the proportion of EPDM is minimum, is all widely used in various fields.But, produce on EPDM material because of the increase of consumption viscosity strengthen, it is impossible to guarantee injection moulding and injection technique be smoothed out more have shortcoming wear-resisting, that anti-slip effect is not good, thus having limited to the scope of its processed and applied.
China Patent Publication No. is CN101747564B, theme is the patent of invention of a kind of high-flow EPDM material and preparation method thereof, it utilizes its formula and preparation technology that EPDM has been modifiied so that it is mobility has reached the requirement of Shooting Technique, strengthens the intensity of EPDM simultaneously.But, in footwear material field, elastomeric material not only to have higher intensity and the characteristic being easily worked, to elasticity, cushioning ability, on-slip with ageing-resistant have higher requirement equally.
Summary of the invention
Present invention aims to the problems referred to above, it is provided that meet that Shooting Technique requires, heat resistant, wear-resisting, on-slip, the hot controllability high polymer elastic composite rubber material of a kind of TCR that intensity is high, elastic strong.
In order to reach the effect above, the technical solution used in the present invention is: a kind of hot controllability high polymer elastic composite rubber material of TCR, described material is formed by following Raw material processing: elastomeric material, olefin block copolymers, injection material, ethylene-octene copolymer, foaming agent, vulcanizing agent, rubber chemicals, filler, activating agent and accelerator；Wherein the weight portion of elastomeric material is 60-70 part, the weight portion of olefin block copolymers is 15-20 part, the weight portion of injection material is 20-30 part, the weight portion of ethylene-octene copolymer is 5-10 part, and the weight portion of foaming agent is 4-6 part, and the weight portion of vulcanizing agent is 0.3-2 part, weight portion 0.3-2 part of accelerator, the weight portion of rubber chemicals is equal to the 1-3% of elastomeric material, and the weight portion of filler is equal to the 5-15% of elastomeric material, and the weight portion of activating agent is equal to the 3-5% of elastomeric material.
Further, described injection material is mixed by the raw material of following weight ratio: ethylene-vinyl acetate copolymer 60%-70%；Ethylene propylene diene rubber 30%-40%.
Further, described filler is nano-calcium carbonate.
The beneficial effect of the hot controllability high polymer elastic composite rubber material of a kind of TCR of the present invention has:
One, this materials'use tradition elastomeric material mixed olefins block copolymer, as material modified, improve tradition injection material injection technique unstability in actual injection moulding is applied and is subject to the shortcoming of bigger limitation and the performance of final finished physical property.
They are two years old, olefin block copolymers in formula also can make original tradition injection its crafters density of finished product of making of material thus increase, aperture diminishes and becomes fretting map technical finesse and improve its uniformity, the density making material diminishes, resilience and elongation at break significantly improve, and tensile strength and hardness reduce.
Its three, this material possesses the heat resistant of traditional cross-linking vulcanized rubber, wear-resisting, the every excellent properties of on-slip, possesses again the low-density characteristic of foaming EVA simultaneously.
