Manufacturing process for sponge with anions

Abstract

The invention discloses a manufacturing process for a sponge with anions. The manufacturing process comprises the following steps that 1, 100 parts of polyether and 15-30 parts of anions are mixed and ground; 2, heat insulation and soaking are carried out at the temperature of 22-24 DEG C for 24 h; 3, 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 tin and 0..04-0.06 part of MDI are added; 4, high-speed stirring is carried out at the temperature of 22-24 DEG C for 15-20 s, and foaming reaction is carried out for 20-50 min; 5, a foaming machine sprays out liquid materials, the liquid materials fall to a conveying belt paved with bottom paper, top paper conveyed synchronously along with the conveying belt is arranged above the conveying belt, the top paper is wound and laid above the liquid materials through a winding drum, the top paper is flatly laid above the liquid materials through a pressing mechanism, side films are arranged on the two sides of the conveying belt, the liquid materials are wrapped by the side films, the bottom paper and the top paper so as to be conveniently conveyed by the conveying belt into a drying box to be heated and cured, and cured materials are molded into a long sponge block which is conveyed, cut and transferred to a finished product collection place.

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.
