给水管用PVC的改性研究

Study on Modified Poly(vinyl chloride)

采用活性碳酸钙和甲基丙烯酸甲酯-丁二烯-苯乙烯三元接枝共聚物(MBS)对PVC进行改性,研究了二者对改性PVC抗冲击性能的影响。结果表明,活性碳酸钙和MBS的加入,改性PVC的抗冲击性能可提高17.3%,改性PVC管在低温下的抗冲击性能得到明显提高。

I he mOClltlecl poty （vinyl chloncte） was prepared using active （SatSO3 and methyl methacrylate butadiene-styrene copolymer （MBS） as modifiers. The influence of CaCO3 and MBS on the impact performance of PVC was studied. The resuks showed that the impact strength of PVC could be improved 17.3% and the cold-resistance performance was also improved with the addition of CaCO3 and MBS.
