Preparation method of epoxy floor spraying material

The invention discloses a preparation method of an epoxy floor spraying material, and the method comprises the following steps: preparing a component A, namely preheating 40-60 parts of hydrogenated phenylmethane diisocyanate, adding 40-60 parts of polytetramethylene ether glycol, heating, cooling, sealing and storing; preparing a component B, namely, mixing and stirring 30-60 parts of amine-terminated polyether amine and 30-60 parts of polyaspartic acid ester, adding 1-5 parts of polyurea color paste, stirring, adding 1-5 parts of an adhesion promoter, stirring, filtering, discharging, sealing and storing; heating the component A and the component B to 55-65 DEG C respectively, and under the pressure of 2000-2500 PSI, performing impact type mixing on the component A and the component B ina spray gun nozzle. The epoxy floor spraying material has the beneficial effects of good elasticity, high flexibility, good temperature change resistance, no embrittlement at-40 DEG C, wear resistance, skid resistance, shock
