摘　　要：用天然松香与二元醇、二元酸和甲苯二异氰酸酯(TDI)合成了不饱和聚氨酯树脂,再加入稀释剂苯乙烯配制成家具涂料。采用国标方法对家具涂料的柔软性、硬度、抗冲击性、固化收缩率、附着力等物理性能进行测试。结果表明,不同二元醇对合成UP/PU树脂家具涂料的性能影响较大,其中乙二醇型UP/PU的聚酯家具涂料且具有优良的抗冲击性、硬度较高、附着力好、固化收缩率低等优越性能。The PU/UP unsaturated polyester have been synthetized by rosin, diatomic alcohol, diprotic acid and toluenediisocyanate （TDI）, and the furniture coatings have been confected by adding styrene diluting agent into the PU/UP unsaturatedpolyester. Such physical property as softness, hardness, impact resistance, curing shrinkage, adhesion was investigated by aseries of performance test method. The results indicated that the type of diatomic alcohol has a obviously effect on the propertiesof the furniture coatings, and those synthetized by using ethanediol as reagent possess very excellent physical properties.
