Problems solved by technology

[0002] Due to the poor anti-skid effect of ordinary polyurethane for shoes, especially some polyurethane midsole materials for shoes, in order to meet the anti-skid requirements of customers, a thin layer of polyether-type low-hardness transparent non-slip must be poured before the midsole material is poured. material, increase the anti-slip effect of the product, and the sole produced by the shoe resin of the present invention has low hardness, good anti-slip effect, easy processing, good elasticity, hydrolysis resistance, and good adhesion with polyurethane midsole insole. Colorants of different colors are made into transparent bottoms of various colors, which are very popular among consumers. However, the common polyether resin products for shoes on the market are poor in elasticity. Bubbles, resulting in poor transparency, some products have poor strength and will break as soon as they are torn, and the defective rate is high

Embodiment Construction

[0022] The forming and processing conditions of the resin for shoes of the present invention are as follows: component A and component C are pre-mixed as material A, taken out and directly reacted with material B, and casted at one time.

[0023] (1) Manual operation: Weigh 100 parts of component A and 40 parts of component B, pour them into the mold cavity for 5-9 seconds under strong stirring at 2500r / min to foam.

[0024] (2) Mechanical operation: the mixture of component A is added to the material tank A of the shoe machine, and the component B is added to the material tank B of the shoe machine, and it is casted at one time through the high-speed stirring of the machine head.

[0025] (3) The mixing equivalent of component A is about 80, the pressure of pump A is 0.35-0.40MPa, and the material temperature is 30-35°C, which is close to room temperature.

[0026] The mixing equivalent of component B is 215±5; the pressure of the pump is 0.41-0.46MPa, and the material temper...

Abstract

The invention belongs to three-component polyurethane resin for shoes, and in particular relates to low-hardness transparent polyether resin for antiskid shoes, wherein a component A refers to polyether glycol containing oxhydryl (OH) group, a component B refers to a performed polymer containing isocyanate NCO group, and a component C refers to a glycol solution containing trimethylene diamine; and the component A and the component C are mixed to form a material A, and the material A is taken as a component and subjected to chemical reaction with the component B. The low-hardness transparent polyether resin for the antiskid shoes is stirred at a high speed by a foaming machine for low-pressure shoes, injected into a die by means of injection molding, and is subjected to a one-step injection molding. Materials of the formula have low viscosity, good fluidity and wide foaming range, and are not required to be heated before use; and sole products are antiskid and transparent.

Description

technical field [0001] The invention belongs to a three-component polyurethane shoe resin, in particular to a polyether-type low-hardness transparent anti-skid shoe resin. Component A is polyether polyol containing hydroxyl (OH) group, component B is prepolymer containing isocyanate NCO group, component C is ethylene glycol solution containing trimethylene diamine, component A Mixed with component C to form A material as a component to chemically react with component B. After high-speed stirring with a foaming machine for low-pressure shoes, it is injected into the mold for one-time injection molding. Background technique [0002] Due to the poor anti-skid effect of ordinary polyurethane for shoes, especially some polyurethane midsole materials for shoes, in order to meet the anti-skid requirements of customers, a thin layer of polyether-type low-hardness transparent non-slip must be poured before the midsole material is poured. material, increase the anti-slip effect of t...
