| 目的 开发一种低导热系数的功能涂料，应用于某重型车辆，以阻隔动力舱与驾驶舱之间的热量传递。方法 研究聚酯多元醇树脂与多异氰酸酯固化剂的配比、低导热系数功能填料与成膜物的配比以及两种不同粒径的空心微珠复配比例对漆膜导热系数、附着力、断裂伸长率等性能的影响，确定阻隔型隔热涂料的最佳配方。采用自制隔热测试装置对涂料的隔热性能进行测试。结果 选用多异氰酸酯作为固化剂，实现漆膜常温固化。聚酯多元醇中羟基(—OH)与多异氰酸酯(—NOC)的最佳物质的量的比为0.8~1.0，低导热系数功能填料与成膜物的最佳质量比为1.5~2.0。漆膜附着力不小于4 MPa，断裂伸长率不小于50%，导热系数小于0.06 W/(m.K)，漆膜密度小于0.5 g/cm3。隔热涂层经120 ℃/2 h的测试，涂层冷面温度未超过45 ℃。结论 研制的阻隔型隔热涂料具有优异的隔热性能，在某型车辆动力舱与驾驶舱之间进行应用与隔热性测试(涂层厚度1.5~2.0 mm、车辆持续工作3 h)。结果表明，驾驶舱一侧隔板的表面温度未超过38 ℃，隔热效果显著。 |

| To develop a kind of functional coating with low thermal conductivity, and study the effect of preventing from heat transfer between engine cabin and cockpit of a heavy vehicle with the coating material. The high-elasticity polyester polyol and the low thermal conductivity functional filler were researched as main objects, the effects of the ratio of polyester polyol resin to curing agent were studied, and low thermal conductivity functional filler to film-forming and two kinds of hollow microsphere were blended on the thermal conductivity, adhesion and elongation at break of the film to determine the best formula of barrier heat insulation coating.The self-made heat insulation test device was used to test the thermal insulation performance of the coating. Experimental evaluation showed that paiting film was cured at room temperature by using polyisocyanate as curing agent, the optimum mole ratio was determined that hydroxy (—OH) to polyisocyanate (—NOC) is 0.8~1.0 and the weight ratio of functional filler to film-forming was 1.5~2.0. Performance testing of paint film showed that the adhesion was not less than 4 MPa, and the elongation at break was not less than 50%, furthermore, thermal conductivity of film was less than 0.06 W/(m.K), and the density is only 0.5 g/cm3; When one side of paint film was kept for 2 h under the condition of 120 ℃, the temperature of another side that didn’t touch heat source was less than 45 ℃ and the temperature difference reached 75 ℃.The barrier heat insulation coating developed in this paper has excellent heat insulation performance. When the coating was painted between the powering section and the driving compartment, the vehicle continued to work for 3 h and surface temperature of the driving cab was below 38 ℃, and the film thickness was only 1.5 mm~2.0 mm. |
