Abstract
The disclosure provides a polyurethane-acrylate water repellant prepared by double bonds in the side chain, and belongs to the technical field of environment-friendly polymers. The disclosure introduces the carbon-carbon double bonds into the polyurethane side chain through a carbon-carbon double bond-containing dihydroxy micromolecular chain extender having a carbon chain structure to adjust the number of double bonds on a waterborne polyurethane chain segment participating in a free radical polymerization with acrylate monomers, thereby generating a branched structure, and improving the compatibility of polyurethane and acrylate; the fastness of a fabric is increased by combining an oxime blocking structure with the fabric. The polyurethane-acrylate water repellant prepared by the disclosure is non-toxic and low in VOC, and the finished fabric has significantly improved physical and chemical properties, and good application prospects.
