▎ 摘　　要

NOVELTY - Anti-scour radiation heat insulation coating comprises bonding primer layer and high emissivity layer, where the primer layer of the bonding layer is formed by solidifying the primer layer of the bonding, the high emissivity layer is formed by curing high emissivity coating, the thickness of the coating layer bonding the primer layer is 2-30 microns, the coating thickness of the high emissivity layer is 20-50 microns, the infrared emitting rate of the anti-scour radiation heat insulation coating is not less than 85 %, the adhesive force of the coating on the titanium alloy is not less than 4.0MPa, the adhesive force of the coating after heat treatment at 700 degrees centigrade per 10 min is not less than 2.0 megaPascal, and the bonding of the primer layer is less than 20 micrometer. USE - Anti-scour radiation heat insulation coating used for titanium alloy and in high speed aircraft, weapon (claimed). ADVANTAGE - The anti-scour radiation heat insulation coating is convenient to use air spraying, has good adhesion and good anti-high speed airflow flushing ability after high temperature heating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a anti-scour radiation heat insulation coating, involving: a. spraying and curing the primer layer to bonding the primer layer bonding then spraying and curing the high emissivity coating to obtain high emissivity layer, bonding primer layer, firstly spraying sand to the titanium alloy to remove the oxide layer, the primer for bonding air, adjusting the viscosity before spraying, the primer spraying is surface drying, and curing heating obtain the primer coating; and b. high emissivity coating for air spraying, before spraying the A component and B component are mixed uniformly, and adjusting the viscosity, coating after coating for surface dry heating, and curing to obtain product.
