The high wear-resisting polyurea coating is a lining wear-resisting layer material suitable for mine clastic rock transportation, vibratory screening and sediment-containing water pipe transportation as well as site operation. In the traditional related wear-resisting techniques, a polyurethane pouring process is used commonly; since the polyurea coating needs to be prefabricated and cannot be manufactured on spot under the restriction of shapes and assembly structure of wear-resisting components, the application on multiple complex occasions are limited. Currently, a universal type polyurea material is used, the spray device with the reaction raw material volume ratio of VA to VB being 1:1 is adopted for construction, the degree of chemical cross linking of the raw material is obviously lower than the polyurea pouring body, and an optimal wearing-resisting effect can not be achieved in the application of the high wear-resisting polyurea material due to the limitation of application device.
