Polyurethane elastomer with increased frictional coefficient and manufacturing process thereof

Abstract

The invention relates to a polyurethane elastomer with an increased frictional coefficient and a manufacturing process thereof. The manufacturing process of the polyurethane elastomer with the increased frictional coefficient comprises the following steps of mold assembly, specifically, all components of a mold are assembled, the whole mold is mounted at a fixed position, and an injection moldingcomponent is fixed in the mold to complete assembly; pre-heating, specifically, the assembled mold is preheated to be dried to avoid internal residues and then is cleaned; and casting, specifically, polyurethane elastomer castable is poured in a mold cavity, and a cylinder is started to drive an upper mold body to be downward clamped in the mold cavity to extrude the castable for a period of time.According to the polyurethane elastomer with the increased frictional coefficient and the manufacturing process thereof, a cooling device is additionally arranged in a lower mold body, so that standing for cooling for a period of time is not needed anymore after molding by casting, and unnecessary time waste is reduced; and cooling liquid can be injected into the mold cavity to rapidly cool a molded product, so that the waiting time is shortened, and the manufacturing efficiency is improved.
