Processing technique of shoe material sponge with negative ions

Abstract

The invention discloses a processing technique of shoe material sponge with negative ions. The shoe material sponge comprises 100 parts of polyether, 15-30 parts of negative ion powder, 0.5-1.5 parts of water, 0.0005-0.0012 part of stabilizer and catalyst, 0.0008-0.0015 part of electrostatic agent, 0.00002-0.0002 part of stannum and 0.04-0.06 part of MDI, silicone oil is adopted as the stabilizer, amine is adopted as the catalyst, and the weight ratio of the silicone oil to the amine is 1:2. The healthcare sponge prepared through the processing technique can release a lot of negative ions with the concentration far higher than the concentration of negative ions in air, and shoe materials or garment interlinings and the like made with the sponge have healthcare effect of sterilization, dust fall and the like and are safer and more environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of sponge processing, in particular to a processing technology for adding negative ion components into sponge. The sponge prepared by the method is used for processing shoe material raw materials, and can obtain high negative ion content, environmental protection and safety, and is beneficial to human health. sole or insole material. Background technique [0002] The current polyurethane sponge is polymerized from polyether polyol and isocyanate. It has the characteristics of good elasticity and softness, and can be used as lining for clothing and shoes. But owing to this sponge in the prior art, its gas permeability, abrasion resistance, environmental protection and health care etc. are relatively deficient. [0003] In order to improve this defect, people began to add negative ion components into the sponge to improve its health care effect. For example, the authorized announcement number is: "A kind of ...

AI Technical Summary

Problems solved by technology

But because above-mentioned first 2 kinds of health-care sponges all make the composition that can release negative ions be attached on the sponge by the mode of viscose bonding, its effect is relatively poor; This kind of raw material is processed by foaming, but it does not disclose the specific ingredients and proportions. Because the negative ion powder is very easy to lose efficacy during the processing process, the finished sponge cannot release negative ions, so its health care effect cannot be verified.
