Embodiment Construction

[0015] This embodiment is a specific application of adding SEBS as a foaming agent in the preparation process of sports materials.

[0016] When 5628-F is introduced into the EVA foam material or foamed with pure 5628-F, the foam material will become softer in touch and softer in hardness, with a high-quality feeling similar to rubber foam material. It has good dimensional stability when used in sports shoes, good thermal stability during container transportation, small compression deformation and good surface haze when made into insoles. For example, in the process of making insoles, EVA can also be modified to resist compression and deformation.

[0017] When 8500-F is introduced into the EVA foam material, the expansion rate will increase under the condition that the hardness of the foam material remains unchanged, so the specific gravity of the foam material will also decrease, so as to achieve the purpose of lightweight modification . Therefore, the outsole in the shoe ...

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 [0001] The invention relates to the application of SEBS as a foam modifier, in particular to the application of SEBS as a foam modifier in the preparation process of sports equipment. Background technique [0002] SBS is a styrene-based thermoplastic elastomer, which has physical properties similar to vulcanized rubber without being vulcanized. It can be directly injection molded and can be 100% recycled. However, the main chain of SBS contains a large number of aliphatic double bonds, which has poor resistance to ultraviolet rays, ozone and heat, and is easy to deteriorate, so its application range is still subject to many restrictions. Therefore, the second-generation styrene-based thermoplastic elastomer styrene-ethylene / butylene-styrene segment SEBS (styrene block copolymer) came into being. SEBS uses hydrogenation to saturate aliphatic double bonds in order to expand the range of product applications. As a saturated thermoplastic elastomer, SEBS has be...
