▎ 摘  要

NOVELTY - A thermal protective coating comprises component A and component B. The component A comprises 100 pts. wt. organic silicon resin, 10-60 pts. wt. coated composite heat-resistant flame-retardant filler, 1-20 pts. wt. reinforcing filler, 3-40 pts. wt. composite anti-corrosion filler, 3-25 pts. wt. pigment, 0.2-5 pts. wt. adhesion promoter, 0.1-6 pts. wt. mildew preventive agent, 0.1-3 pts. wt. UV absorbent and 5-55 pts. wt. solvent. The component B comprises 3-20 pts. wt. curing agent and 5-25 pts. wt. solvent. The weight ratio of component A to component B is 100:5-30. USE - The thermal protective coating is used for marine environment (claimed) in heat protection of high temperature portion comprising tactical missile, marine launch rocket and ship engine for a long time. ADVANTAGE - The coating has high strength, high temperature resistant ablation, salt spray resistance, damp heat resistance, UV aging resistance and good compatibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing thermal protective coating comprising respectively mixing component A and component B.
