摘　　要：介绍了无溶剂聚氨酯改性环氧树脂及无溶剂隔热涂料的制备方法。对树脂、涂料的热性能进行了评价。结果显示,无溶剂聚氨酯改性环氧树脂隔热涂料的拉伸强度大于10MPa,断裂伸长率大于3%,附着力大于10MPa,室温下比热容1.26kJ/(kg·K),隔热参数为0.07kg2/(m4·s),隔热效率0.175W/(m2·K),综合性能优良。We have first prepared solvent-free PU modified epoxy resin and then solvent-free heat-insulating coatings. On evaluating the properties of resin and coatings, we have got that the tensile strength of the solvent-flee PU modified epoxy heat-insulating coatings is more than 10 MPa, elongation at break is more than 3%, adhesion is more than 10MPa, and specific heat capacity under room temperature is 1.26 kJ/（kg.K）, heat insulation parameter is 0.07kg2/（m4.s） and heat insulation efficiency is 0.175 W/（m2.K）.
