Problems solved by technology

[0002] Traditional soft foamed footwear materials mainly use POE, SEBS and other elastomers for blending and modification, and the purpose of reducing the hardness of the material is achieved by increasing the foaming ratio. The product material has a clear sense of plastic and its physical properties are greatly reduced.

Abstract

The invention discloses a foaming material of a propylene based elastomer. The foaming material is prepared from the following raw materials in parts by weight: 40-80 parts of a propylene based elastomer, 10-30 parts of modified resin, 20-40 parts of a filler, 0.8-1.4 parts of a cross-linking agent, 0.5-1.5 parts of a cross-linking accessory ingredient, 6-10 parts of a foaming agent, 0-1.6 parts of a foaming accessory ingredient and 0-1.6 parts of a lubricating agent. The foaming material of the propylene based elastomer prepared by using the above technical scheme is excellent in comprehensive properties, has the characteristics of high flexibility, high elasticity, low hardness, light weight, great foaming ratio and simple production process and can be widely used in the fields of shoe materials, sports auxiliary materials and package.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a foaming material, in particular to a propylene-based elastomer foaming material. Background technique [0002] Traditional soft foamed footwear materials mainly use POE, SEBS and other elastomers for blending and modification, and the purpose of reducing the hardness of the material is achieved by increasing the foaming ratio. The product material has an obvious plastic feel and its physical properties are greatly reduced. [0003] Vistamaxx TM Propylene-based elastomers are based on ExxonMobil Chemical's proprietary Exxpol TM Olefin elastomers produced by metallocene technology. They are unique semi-crystalline propylene-ethylene copolymers. In Vistamaxx TM In propylene-based elastomers, the mainly amorphous propylene-ethylene (EP) matrix is ​​embedded in a network of fine, uniformly dispersed isotactic polypropylene (PP) crystals, thereby obtaining elasticity. When blended...
