Abstract

The invention discloses an anti-static polyurethane material for manufacturing shoe soles, a shoe sole manufacturing method and a manufacturing method of dual-density polyurethane safety shoe soles. The anti-static polyurethane material consists of a component A and a component B which are mixed and poured, the component A includes polyatomic alcohol, catalyst, foaming agent, anti-static agent, carbon fiber powder, chain extender and defoaming agent; and the component B is isocyanate. The shoe sole manufacturing method includes steps of baking and drying the polyatomic alcohol and the isocyanate, mixing the rest compositions in the component A and the baked polyatomic alcohol uniformly to form material A, and mixing the material A with the isocyanate of the component B to obtain shoe soles made of anti-static polyurethane materials by pouring forming. The dual-density polyurethane safety shoe soles can be manufactured by secondary pouring by selecting foaming agents in different quantity. The polyurethane materials are high in anti-static performance, and the manufactured shoe soles are proper in hardness. Shoe soles manufactured by the manufacturing methods are fine in demouldingand high in production efficiency.

Description

technical field [0001] The present invention relates to a shoe sole material and a manufacturing method thereof, in particular to an antistatic polyurethane material used for manufacturing shoe soles and a shoe sole manufacturing method using the material, a method of manufacturing double-density polyurethane safety shoe soles, and the shoe sole material of the present invention It is mainly used in places where static electricity may cause combustion and explosion due to static electricity on the human body, such as workplaces in petroleum, chemical, coal mine, printing, rubber, medical, purification, electronics and other industries. Background technique [0002] Anti-static safety shoes are a kind of protective shoes with anti-static function. The special place of use makes it have certain requirements for the hardness of the sole and anti-static performance. Commonly used safety shoes are PU material, TPU material rubber material and PVC material. of four. [0003] In a...
