Problems solved by technology

[0002] Insoles are a kind of daily necessities commonly used by people. In the production process of insoles, it is often necessary to foam the production raw materials, and then cut them according to the thickness of the insoles. Cut and cut according to the required shape, and finally print the pattern on the fabric. The production process of such insoles is too complicated, which is not conducive to the rapid and effective development of production.

Abstract

The invention discloses a preparation method of a modified waterborne polyurethane insole. The preparation method comprises the following steps: stirring and mixing a waterborne polyurethane prepolymer emulsion, rubber latex, a foaming agent, a foam stabilizer, a catalyst and a hardening agent to form modified waterborne polyurethane; injecting the modified waterborne polyurethane into an insole mold, and heating for foaming formation; taking out an insole after foaming formation out of the mold, and excising residual corners on the insole. According to the preparation method of the modified waterborne polyurethane insole provided by the invention, the production of the insole is carried out by using the method, the production procedure of the insole is simplified, the production of the insole is quicker, the manpower and material resources are saved, and then the production cost is reduced.

Description

technical field [0001] The invention relates to the field of insole preparation. Background technique [0002] Insoles are a kind of daily necessities commonly used by people. In the production process of insoles, it is often necessary to foam the production raw materials, and then cut them according to the thickness of the insoles. Cutting and cutting according to the required shape, and finally printing the pattern on the fabric, the production process of such insoles is too complicated, which is not conducive to the rapid and effective development of production. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide a preparation method of modified water-based polyurethane insoles, utilize this method to carry out the production of insoles, simplify the production process of insoles, make the production of insoles faster, save manpower and material resources, and then reduce Cost of production.
