Embodiment Construction

[0024] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0025] Such as figure 1 As shown, an improved expanded particle 10 related to the present invention includes a cylindrical elastic body 11, and the cylindrical elastic body 11 is formed with a through hole 12 in the middle position, and the cylindrical elastic body 11 is extruded The shaped cylindrical particles 40 with holes are made by foam molding.

[0026] Wherein, the shape of the cylindrical elastic body 11 is a cylinder composed of a cylindrical side surface 111 , an upper bottom surface 112 and a lower bottom surface 113 , and the through hole 12 is an upper and lower through hole extending along the central axis.

[0027] Such as figure 2 As shown, an improved foam molding 20 related to the present invention includes several cylindrical elastic bodies 11 and an adhesive layer between adjacent cylind...

Abstract

The invention discloses an improved foaming particle, a molded body and a production process of the improved foaming particle. The improved foaming particle comprises a cylindrical elastomer, whereina through hole is formed in the middle position of the cylindrical elastomer, and the cylindrical elastomer is prepared by foaming and molding extruded cylindrical particle with holes. Compared with the prior art, the improved foaming particle, the molded body and the production process enrich the types of foaming particles, the weight of the particles per unit volume can further be reduced, and the cushioning performance of products can be improved to a certain extent.

Description

technical field [0001] The invention relates to the field of shoe materials, in particular to an improved foamed particle, a molded body and a production process thereof. Background technique [0002] At present, due to the research and development of TPU materials, it has brought new vitality to the market. The common etpu popcorn soles on the market are generally obtained by foaming oval TPU particles first to obtain oval TPU foamed particles, that is, etpu particles; then put the etpu particles into the mold, and get the shock-absorbing sheet in the mold by steam foaming, and finally brush a layer of glue on the bottom of the shock-absorbing sheet, and through the glue layer A layer of rubber is connected to form a sole with better performance in terms of wear resistance, anti-slip and shock absorption. [0003] The above-mentioned etpu particles can meet most of the use requirements, but because they are basically solid, they are relatively heavy in weight, and it is di...
