Abstract

The invention relates to a directly-formed high-air-permeability polyurethane insole composite material and a preparation method thereof, and belongs to the technical field of polyurethane. The directly-formed high-air-permeability polyurethane insole composite material is prepared from a component A and a component B, wherein the component A is prepared from polyether polyol 1, polyether ester polyol 2, polyether polymer polyol 3 and other auxiliary agents, and the component B is prepared from polyether ester polyol 2, polyether polyol 4, isocyanate and 10-30 ppm of a storage stabilizer. According to the directly-molded high-air-permeability polyurethane insole composite material disclosed by the invention, the air permeability of an insole prepared from the directly-molded high-air-permeability polyurethane insole composite material is remarkably enhanced. The invention also provides a simple and feasible preparation method.

Description

technical field [0001] The invention relates to a directly formed highly breathable polyurethane insole composite material and a preparation method thereof, belonging to the technical field of polyurethane. Background technique [0002] Polyurethane materials have been widely used in the production of insoles, mainly due to the superior resilience and good mechanical properties of polyurethane materials. [0003] At present, there are two typical processes for the production of polyurethane foam insoles. One is the direct molding process. This process is to inject the mixed composite material into the prefabricated single-piece insole mold, and directly obtain the finished insole after the mold is opened. The advantages are: Direct molding, simple process, and good mechanical properties of the product, but the surface is generally crusted resulting in poor air permeability; the other is the slicing process, which is to inject the mixed composite material into a large-sized m...
