The invention belongs to the technical field of waste cloth recovering and reusing, and particularly relates to waste-cloth-containing recovered fiber coating slurry and coating, and a preparation method thereof. 0.5-8 parts by weight of recovered fiber of waste cloth, 95-110 parts by weight of waterborne polyurethane, and 4-6 parts by weight of curing agent are prepared into recovered fiber coating slurry. The recovered fiber coating slurry is printed on a base cloth or a base plate, and dried to obtain a recovered fiber coating having a thickness of 0.1-1.0 mm. According to the technical solution provided by the invention, the field of physical method recycling of waste cloth is expanded to coating. Because the particle size of recovered fiber of the waste cloth is fine, the recovered fiber coating obtained by mixing waterborne polyurethane with a curing agent in a proper proportion has excellent abrasion resistance and mechanical properties.

The present invention relates to an aqueous dispersion of polymeric microspheres with a high surface Young's modulus and a relatively low core Young's modulus.
