Problems solved by technology

[0002] In the prior art, insoles are generally composed of an elastic bottom layer and a cloth surface layer. During production, the elastic bottom layer is first made, then glue is applied on the surface of the elastic bottom layer, and the cloth layer is pasted, and then cut and trimmed. The finished product has the following disadvantages: it needs to be pasted with glue, there are many processes, and the quality of the bonding between the two layers of the insole is not high;
[0004] At the same time, foot movement will produce a lot of sweat, the breeding of bacteria on the feet, and reduce the comfort of the foot environment. The current insoles have the disadvantage of poor porosity, resulting in poor air permeability.

Abstract

The invention discloses a compression-resistant and breathable insole, which is composed of the following raw materials in parts by weight: Eva 25-30, polyolefin thermoplastic elastomer 20-30, thermoplastic polyurethane elastomer 35-40, and nucleating agent 1-30 3. Foaming agent 2-3, zinc oxide 1-2, stearic acid 0.4-0.6, bridging agent 0.4-0.6, elasticity enhancer 0.4-1, the finished insole of the present invention has good pressure resistance and high resilience , high wearing comfort and superior quality.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a compression-resistant and breathable insole. Background technique [0002] In the prior art, insoles are generally composed of an elastic bottom layer and a cloth surface layer. During production, the elastic bottom layer is first made, then glue is applied on the surface of the elastic bottom layer, and the cloth layer is pasted, and then cut and trimmed. The finished product has the following disadvantages: it needs to be pasted with glue, there are many processes, and the quality of the bonding between the two layers of the insole is not high; [0003] When a person is exercising, it is done through the strength of the foot, so that the impact force of a relatively large load is concentrated on the foot; therefore, an insole with better resilience can play a good role in shock absorption, buffering effect; [0004] At the same time, foot movement will produce a large a...
