Abstract
The invention discloses a high-temperature heat-insulation flame-retardant coating and a preparation method thereof. The coating consists of two components of polyester heat-insulation flame-retardantslurry and an adduct; the polyester heat-insulation flame-retardant slurry is prepared by mixing adipic acid polyester resin with a flame-retardant filler according to 1:1.2, wherein the adipic acidpolyester resin is prepared from the following raw materials in parts by weight: 33 parts of adipic acid, 24 parts of diethylene glycol, 3 parts of dimethylolpropionic acid, and a proper amount of a solvent consists of xylene and cyclohexanone; the flame-retardant filler consists of the following raw materials in parts by weight: 15 parts of ammonium polyphosphate, 11.9 parts of ammonium pentaborate, 7.38 parts of zinc oxide, 5 parts of starch, 5.95 parts of antimony trioxide and 4.76 parts of talcum powder; and the adduct consists of 2.216 parts of toluene diisocyanate, 1.334 parts of dehydrated trihydroxy methyl propane, 0.3 part of organosilicon isocyanate and a proper amount of cyclohexanone. The high-temperature heat-insulation flame-retardant coating prepared by the method provided by the invention has good comprehensive performance, the fire-resistant limit reaches 9.0 / h or above, and when the temperature of a hot surface is 250 DEG C, the temperature of a cold surface is 75 DEGC or lower in 4 hours.
Description
technical field [0001] The invention relates to the technical field of paint preparation, in particular to a high-temperature heat-insulating flame-retardant paint and a preparation method thereof. Background technique [0002] Although the existing heat-insulating and flame-retardant coatings have reached a relatively high level in a single performance index, it is still difficult to meet the stringent requirements in the aviation and aerospace fields with comprehensive indexes such as temperature resistance, flame retardancy, and heat insulation. It mainly has the following disadvantages: [0003] 1. The weather resistance and water resistance of the product generally cannot meet the requirements; [0004] 2. In the event of a fire, the film-forming substances of these coatings cannot withstand the rapidly rising temperature and are quickly burned, and cannot play the role of fire prevention. [0005] 3. Poor performance in anti-corrosion, acid and alkali resistance. ...
