Preparation method of high-resilience gum-dipped labor protection glove coating

The invention provides a preparation method of a high-resilience gum-dipped labor protection glove coating. The method specifically comprises the following steps: adding 60-110 parts by mass of dehydrated polyalcohol and 40-100 parts by mass of isocyanate into a container, uniformly stirring and heating to 60-100 DEG C, adding 3-50 parts by mass of a chain extender and 1-10 parts by mass of a catalyst, reacting for 1-3 hours by controlling the temperature to be 50-95 DEG C, then adding a chain extender solvent, reacting for 1-3 hours at 50-80 DEG C until the content of isocyanate groups is constant, and cooling to obtain a polyurethane prepolymer; neutralizing the polyurethane prepolymer by using an amine neutralizer, adding water for emulsifying to obtain a waterborne polyurethane emulsion, removing the solvent to obtain polyurethane resin, adding 1-10 parts by mass of a wetting dispersant, 1-5 parts by mass of a flatting agent and 1-20 parts by mass of a foam stabilizer, and stirring for 30 minutes under no
