Polyurethane emulsion and coating agent used for aquosity coating agent of knitted lining glove as well as preparation method and coating method thereof

The invention discloses a polyurethane emulsion used for aquosity coating agent of knitted lining glove and a preparation method thereof. In the preparation process, no softening agent, coupling agent, or a crosslinking agent is needed to be added, and the invention aims to replace oil-soluble polyurethane products to prepare the aquosity coating agent of the knitted lining glove. In the invention, the aquosity coating agent is obtained by mixing aquosity polyurethane emulsion with auxiliary materials, and is coated on a glove through the steps of immersing into the coating agent, solidifying and shaping, and washing and drying. The aquosity coating agent prepared by the method is environmental friendly without pollution and is beneficial to protect the health of workers, and the glove has the advantages of good mechanical performance, cutting resistance, penetrating resistance, good grabbing performance, waterproof and air permeability, comfortable hand feel and flexible operation.
