NOVELTY - A coating includes 30-40 pts. wt. polyether urethane resin, 30-45 pts. wt. vinyl polyorganosiloxane, 10-14 pts. wt. silicone oil, 5-8 pts. wt. expanded vermiculite, 1-10 pts. wt. thermal expansion microcapsules, 0.5-1 pts. wt. chloroplatinic acid, 0.4-0.5 pts. wt. silazane, 1.5-1.6 pts. wt. sodium lauryl sulfate, 1-2 pts. wt. vegetable gum, 0.5-0.8 pts. wt. anti-wear agent, 43-45 pts. wt. barium sulfate powder, 6-8 pts. wt. wood cellulose, 3.5-4.5 pts. wt. silane coupling agent, 1-3 pts. wt. diatomite, and 3-5 pts. wt. nanosilica.    USE - Coating for windproof textile material (claimed).    ADVANTAGE - The coating has excellent windproof, air permeable, and moisture-permeable effect, and soft fabric hand feeling.    DETAILED DESCRIPTION - Coating comprises 30-40 pts. wt. polyether urethane resin, 30-45 pts. wt. vinyl polyorganosiloxane, 10-14 pts. wt. silicone oil, 5-8 pts. wt. expanded vermiculite, 1-10 pts. wt. thermal expansion microcapsules, 0.5-1 pts. wt. chloroplatinic acid, 0.4-0.5 pts. wt. silazane, 1.5-1.6 pts. wt. sodium lauryl sulfate, 1-2 pts. wt. vegetable gum, 0.5-0.8 pts. wt. anti-wear agent, 43-45 pts. wt. barium sulfate powder, 6-8 pts. wt. wood cellulose, 3.5-4.5 pts. wt. silane coupling agent, 1-3 pts. wt. diatomite, 10-12 pts. wt. inhibitors, 3-5 pts. wt. nanosilica, 5-7 pts. wt. titanium dioxide, 3-10 pts. wt. UV stable agent, and 25-30 pts. wt. ethanol 25-30. The thermal expansion microcapsules are in thermoplastic resin spherical shell containing volatile substance. The spherical shell components include polyethylene, polystyrene, polybutadiene, polyvinyl acetate copolymers, chloroprene rubber and other polymers. The thermal expansion microcapsules volatile package includes butane, isobutane, propane, and dichloroethane. The coating is prepared by shearing vinyl polyorganosiloxane, nanosilica, silazane and ethanol, mixing for 1-2 hours to obtain uniform mixture, adding thermal expansion microcapsules and chloroplatinic acid catalyst, and filtering to give component (A); adding lignocellulose in reaction kettle, adding barium sulfate powder and diatomaceous earth, mixing, milling for 15-20 minutes, adding component (A), adding the rest of the materials, and stirring to obtain component (B); and mixing and milling through ultrasonic dispersion for 25-35 minutes.
