    Abstract

    This application discloses a hydrophobic automobile rubber seal strip flocking belt and a preparation method thereof. The flocking belt includes a flocking belt film, flocking belt glue, villi and flocking paint. The flocking glue is roller-coated or sprayed on the flocking film to form a flocking glue layer, and the villi is implanted on the flocking glue layer by high voltage static electricity in electrostatic chamber. The flocking paint is roller-coated or sprayed on the villi to form a flocking coating which includes fluorosilicone modified waterborne polyurethane resin, polyurethane modified acrylic emulsion, organic molybdenum, organic silicon, curing agent and solvent. The flocking belt described in this application is installed in a guide groove of the automobile glass, which is enabled to solve the problem of abnormal sounds caused by rising and falling of glass of automobile windows. In addition, the flocking coating feels soft and smooth.
