摘要
利用废弃花蛤壳粉和SEBS,通过熔融共混的方法协同改性PP,发现花蛤壳粉和SEBS可以起到协同增韧、增强PP的效果。当填充质量分数为20%的SEBS和5%的花蛤壳粉时,PP的拉伸强度提高了9%,冲击强度提高了101%,同时PP的结晶速度和结晶度也有了明显提高。利用扫描电镜观察发现SEBS的质量分数超过10%时,PP的断裂行为开始由脆性断裂转变为韧性断裂。
In this research,polypropylene(PP)is synergistically modified by a kind of discarded clam shell powder and SEBS through a method of melt blending.It is found that CSP and SEBS can be used to toughen and enhance the effect of polypropylene.When 20%of SEBS and 5%CSP are filled,the tensile strength of PP increases by 9%;the impact strength of PP increases by 101%;and the crystallization rate and crystallinity of PP increase significantly.Scanning electron microscopy(SEM)shows that the fracture behavior of PP begins to change from brittle fracture to ductile fracture when the addition of SEBS exceeds 10%.
