Abstract
The invention discloses application of an SEBS (styrene-ethylene-butylene-styrene) in a sports equipment preparation process as a foaming modifier. After being modified with an SEBS foaming material, EVA (ethylene-vinyl acetate) has better dynamic viscoelastic property and meets the testing requirement of human engineering; and the properties of EVA are improved in the aspects of flexibility, compressibility resistance, limited slip resistance, elasticity, material stretchability and the like. The SEBS foaming material has the characteristics of good elasticity, plasticity absent in a thermosetting material and rim leftover retrievability.
Description
Technical field
The present invention relates to the application of SEBS, relate to SEBS particularly and in sports equipment preparation technology, use as the foaming modification agent as the foaming modification agent.
Background technology
SBS is a kind of polystyrene thermoplastic elastomer, and it needn't promptly have the physical properties of similar vulcanized rubber through sulfuration, but the direct injection moulding, and one of can percentage hundred recycle.But contain the two keys of great amount of fat family on the SBS main chain, not good to the resistivity of ultraviolet ray, ozone and heat, deterioration makes its range of application still receive many restrictions easily.Therefore, s-generation polystyrene thermoplastic elastomer styrene-ethylene/butylene-styrene fragment SEBS (styrene block copolymer) arises at the historic moment.SEBS utilizes the hydrogenation mode with the aliphatic double bonds saturation, in the hope of enlarging the product application scope.As the SEBS of saturation type thermoplastic elastomer since soft section be the alkene architecture of saturation type, weathering resistance, heat-resistant aging are better than SBS, and rerum natura is also more tough than SBS, so range of application is more extensive.
The SEBS thermoplastic elastomer is a kind of novel high polymer material between rubber and resin, not only can replace part rubber, can also make plastics obtain good modification.SEBS have and traditional rubber phase with elasticity, recovery, obdurability and weathering resistance, and the characteristic of the equally easy machine-shaping of thermoplastics and can reclaim advantage such as use again.And the plastic raw materials of it and other has splendid compatibility; And because SEBS can adjust material softer hardness by adding expansion oil, so can make durometer level foaming product widely, foaming finished product durometer level can be 5-60 ℃; Proportion is extremely low, between 0.08-0.3.SEBS is because of having hot mouldable characteristic, so the moulding article after the foaming also can carry out the secondary typing again making complex-shaped finished product, and the finished product that foams can be recycled.
At present in the sports equipment field, lack a kind of manufacturing materials that can substitute traditional rubber.
Summary of the invention
To above-mentioned defective, the invention provides a kind of method of making high-performance sports equipment material.Particularly, SEBS is used in the preparation sports equipment as the foaming modification agent.More specifically, the present invention uses SEBS in the preparation process of following product.
The purposes as modification agent of SEBS in sports equipment preparation technology.
Preferably, SEBS conduct foaming modification agent in the technology of making sole.
Preferably, SEBS conduct foaming modification agent in the technology of making sports pad.
Preferably, SEBS conduct foaming modification agent in the technology of making yoga mat.
Preferably, SEBS conduct foaming modification agent in the technology of making Shoulder-guard pad, knee pad.
Preferably, SEBS conduct foaming modification agent in the technology of making kickboard, floating bed.
Beneficial effect of the present invention is following.
EVA through after the modification of SEBS foam material has better dynamic viscoelastic matter, and improves the foaming composition of EVA.The test request of ergonomic, its performance at aspects such as flexibility, resistance against compression, on-slip property, elasticity and material extending property all increases.The characteristic of SEBS foam material is splendid elasticity, plasticity-, rim charge returnability that thermosetting material lacked.
In addition, SEBS foam material and various rubber, plastics compatibility are high, can mix the product of different qualities and function according to the difference of prescription base material.
Embodiment
This embodiment is in the preparation technology of move materials, to add the concrete application of SEBS as whipping agent.
When foaming as importing 5628-F in the EVA foaming material or with pure 5628-F, foaming material sense of touch can become softer, and it is softer that hardness also can become, and has the high-quality sense of rubber like foam material.Performances such as use is inserted with dimensional stability in sports shoes good, and the counter process of transporting has heat-resistant quality good, and making shoe-pad has compression set little, and surperficial mist degree is good.For example, in the process of shoemaking pad, also can do the askew modification of compression to EVA.
When importing 8500-F in the EVA foaming material, the foaming material is under the condition that hardness remains unchanged, and expansion ratio can increase, and the proportion of the material that therefore foams also can be along with decline, and reaches the purpose of light weight upgrading.Therefore, the big end, also have the characteristics of on-slip, wear-resisting and incompressible distortion in the footwear.
Below for adopting SEBS carries out modification to EVA testing data.VA18% representes that the content of vinyl acetate between to for plastic among the EVA (VA) is percentage 18, the per-cent of the product type that+X% representes in above-mentioned EVA, to add.
