Problems solved by technology

All surfaces need to be painted, especially not cold-resistant. Although cold-resistant materials are introduced, they still do not meet the low-temperature resistance standard and are easy to split when exposed to cold. Therefore, only sandals and single shoes can be produced, and cotton shoes are almost not made of this material.
Only single-color production is possible. Although double-color production can be produced through machine transformation, it is still based on TPU, which cannot avoid the disadvantage of physical properties: non-recyclable
[0008] The last thing to mention is that the synthetic rubber foam material combined with EVA material and SEBS material currently on the market solves the problems of density and surface roughness, but it needs to be produced by vulcanization process, the output is too low, and the cost price is too high

Abstract

The invention discloses an ultra-light foamed TPR material synthesized of modified thermoplastic rubber and a preparation method thereof, and belongs to the technical field of chemical materials. The invention provides a novel TPR material and a preparation method thereof, wherein the TPR material has the advantages of great foaming capacity, low density, tear resistance, bend resistance and wear resistance, and is produced through the melt blending of acrylonitrile-butadiene rubber, which has high viscosity, and linear three embedded copolymers(SEBS), which uses ethylene-butene copolymers as a middle elastic embedded segment and has high rebound resilience. The novel TPR material and the preparation method have the characteristics of batch production and low production cost.

Description

technical field [0001] The invention relates to rubber materials in the field of chemical materials, in particular to a modified ultra-light foaming TPR material added with SEBS, nitrile rubber and microsphere foaming agent on the basis of traditional TPR and a preparation method thereof. Background technique [0002] At present, there are the following kinds of sole materials on the market, 1. Traditional TPR; 2. Rubber; 3. EVA foam material; 4. Polyurethane foam material; 5. PVC material. [0003] TPR material is one of the main sole materials, fitness equipment materials and toy materials. It has been developed for decades since 1963. The products are constantly updated, but there are still too high density (generally 0.9-1.2 / cm 3 ), and the surface is rough. The density and wear resistance of TPR are generally solved by adding foaming agents and wear-resistant agents on the market. However, due to the decrease in density, the tearing force and bending resistance of the m...
