| 摘 要： | 通过乳液聚合制备了橡胶粒子尺寸为64～420 nm的丙烯腈-丁二烯-苯乙烯(ABS)共聚物.然后将其与SAN-T树脂熔融共混制备橡胶质量分数为15%的ABS树脂.研究了橡胶粒子尺寸对ABS树脂力学性能影响和材料内部形态结构.结果表明:随着橡胶粒子尺寸的增加ABS树脂的冲击韧性提高.当橡胶粒子尺寸在320 nm时,拉伸强度达到最大,ABS树脂的综合性能达到最好.粒子尺寸在64～110 nm时,橡胶粒子在基体内部发生团聚,材料发生脆性断裂.当橡胶粒子尺寸在216～420 nm时,材料主要以韧性断裂为主,发生脆韧转变.具有双峰分布ABS-110nm/ABS-275 nm共混物大、小橡胶粒子间发生明显的协同作用. |

| Abstract: | A series of ABS copolymers with different particle size ranging from 64 nm to 420 nm were prepared via emulsion polymerization.Then ABS resins of 15%rubber content were prepared by melt blending the ABS copolymers with SAN-T resin.Effects of rubber particle size on mechanical properties and morphology of ABS resins were studied.It was found that the impact strength increased with the rubber particle size increasing.When the rubber particle size was 320 nm,the tensile strength was the largest and the compreh... |
