Abstract

The invention relates to a mulling device, in particular to an auxiliary mulling device for improving water resistance of a polyurethane material. The invention provides the auxiliary mulling device with a grinding function for improving the water resistance of the polyurethane material. The auxiliary mulling device for improving the water resistance of the polyurethane material comprises a base, a mixer, a stirring device and a grinding device; a workbench is arranged at the top of the base, the mixer is arranged on the workbench, the stirring device is arranged in the mixer, and the grinding device is arranged at the top of the mixer. Tetrafluoroethylene can be ground into micro powder through the grinding device, to facilitate mixing with a polyurethane raw material in the mixer, the grinding device drives the stirring device to work while working, and automatic stirring operation is achieved.

Description

technical field [0001] The invention relates to a kneading device, in particular to an auxiliary kneading device for improving the water resistance of polyurethane materials. Background technique [0002] Polyurethane is a synthetic material with excellent performance. Compared with other elastomers, it has extremely high mechanical properties, such as extremely high tensile strength, high elasticity under high hardness, and high elongation, which are much higher than those of general-purpose rubber. Wear resistance, these properties make polyurethane suitable for engineering elastomers, such as papermaking, steel rolling rubber kun cladding, solid tires, wear-resistant linings, papermaking shoe pressure sleeves and high-pressure sealing fields. [0003] Since the polyurethane elastomer contains chemical bonds and groups that are easy to hydrolyze, such as ether bonds, ester bonds, isocyanate bonds, hydroxyl groups, and carboxyl groups, the hydrolysis resistance of polyureth...
