轻量化PP/MCHGB/POE复合材料的制备与性能研究
Preparation and Performance Research of Lightweight PP/MCHGB/POE Composites
摘要
Abstract
A variety of silane coupling agents were used to modify hollow glass beads(HGB)to improve the interface compatibility between HGB and polypropylene(PP),and the maximum addition amount of modified HGB was explored.At the same time,low density polyolefin elastomer(POE)was introduced to toughen PP.The results show that the HGB modified by coupling agents has good compatibility with PP and improves the thermal stability of the composites,among which vinyl trimethoxysilane(A-171)has the best modification effect.Compared with the unmodified PP/HGB composites,the tensile strength and bending strength of PP/A-171-HGB are increased by 4.02 MPa and 9.28 MPa,respectively,and the density decreases to 0.902 g/cm3.When 10%modified HGB and 15%POE are added,the balance of rigidity and toughness of the composite can be ensured.Compared with the unmodified PP/HGB composites,the elongation at break of the composite is increased by 73.4%,and the density decreases to 0.864 g/cm3.关键词
