【Abstract】 In order to improve the flexibility, corrosion resistance, water resistance and low temperature curing ability of polyamine curing agent, a new type of tung oil-modified amine(TPH) curing agent was synthesized from tung oil through transesterification, Friedel-Crafts substitution, Mannich base condensation and amidation. The physicochemical indicators were characterized. The effect of the addition amount of monofunctional(benzyl glycidyl ether) and difunctional(1,4-butanediol diglycidyl ether) reactive diluent on the coating properties, and the mechanical properties and anti-corrosion properties of the coating were tested, which were compared with the properties of the cardanol phenalkamine(PCD) cured paint film. The results showed that when the amount of diluent in the anti-corrosion coating was 10%, the tack-free and hard drying time of TPH paint film surface was 40 and 90 min, respectively. Its impact toughness was 80 cm, flexibility was 1 mm, pencil hardness was 5H, and impact resistance was ≥40 cm. Heat resistance(150 ℃±3 ℃, 4 h) showed slightly foaming paint film without falling off, the heat and humidity resistance was 1 000 h under the temperature of 47 ℃±1 ℃, and the relative humidity of 96%±2%, and salt spray resistance showed no rust, no bubbles, and no discoloration(1 500 h). The hardness of aviation kerosene(168 h) was up to 4H, and 4109 engine lubricant(121 ℃±3 ℃, 24 h) and 15# hydraulic oil(66 ℃±3 ℃, 24 h) all showed non-foaming and non-falling off. Compared with PCD film, TPH film had excellent impact flexibility, pencil hardness, high and low temperature resistance and solvent resistance.Key word:更多还原
