Abstract: 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.

Abstract: The invention relates to low baking temperature ultraviolet (UV) radiation curable or thermally curable powder coating polymer materials and compositions for heat-sensitive and/or flexible substrates. More specifically, such powder coating polymer materials and compositions are based on crystalline or semi-crystalline polymers but when subject to melting and flow-out at low temperatures (60° C.-140° C.) and upon curing in molten state by UV radiation or thermal energy, will give a (highly) flexible coating having either complete amorphous, non-crystalline, low glass transition temperature (Tg) polymeric matrix or low degree of crystallinity, low Tg polymeric matrix.
