摘　　要： 用"反应法"制备纳米ZrO2/UPR,是将纳米ZrO2粉在合成不饱和聚酯时加入。用正交优选试验得到合成树脂最佳配方为:二元酸与二元醇的摩尔比是1∶1,饱和酸与不饱和酸的摩尔比是1∶1,纳米ZrO2含量是7%,邻苯二甲酸酐与己二酸的摩尔比是1∶1,过氧化苯甲酰用量为1%。经测试,纳米ZrO2/UPR弯曲强度和冲击强度分别为121.3MPa,10.1kJ/m2,较UPR分别提高28.4%和16.1%,得到了同时增韧增强的树脂。 The nano-ZrO_2/unsaturated polyester resin (referred to as nano-ZrO_2/UPR hereafter) was prepared with the reaction method which the nano-ZrO_2 powder is added as a raw material upon synthesizing the unsaturated polyester resin (UPR) to form nano-ZrO_2/UPR. The optimal formula of the prepared nano-ZrO_2/UPR by the orthogonal experiments is:the molar ratio of the dibasic acid and the dibasic alcohol is 1∶1, the saturated and unsaturated acid is 1∶1, the amount of nano-ZrO_2 powder is 7%, the molar ratio of phthalic annydride and adipic acid is 1∶1, the amount of benzyl peroxide(BPO) is 1%. The bending strength and impact strength of the nano-ZrO_2/UPR are (121.3) MPa and (10.1) kJ/m^2, increases (28.4%) and (16.1%) respectively as compared with that of UPR. So the simultaneous strengthening and toughening resin is obtained.
