摘要
本文在加工设备中采用化学与物理改性相结合的方法对PP——高岭土复合材料的增韧进行了研究。结果表明,该复合体系在PE-g-MAH的存在下,加10份EPDM,体系的缺口冲击强度提高到增韧前的289.7%,无缺口提高到增韧前的342.4%。在MAH、PE、高岭土接枝母料的存在下,EPDM量相同,体系的缺口冲击强度提高到增韧前的324.1%,无缺口提高到增韧前的485.4%。本文还研究了橡胶种类、胶量、高岭土品种及改性工艺对增韧效果的影响,得出胶种以EPDM最好,用量10%,高岭土以超细土的品种为好。
The toughening of PP-kaolin composite by method of combining chemical and physical modifications in processing appara-tus was studied in this paper. The results showed that the notched and no-notched impact strength of the toughened composite,was increased by 289.7% and 342.4% respectively when EPDM (10phr) was added in the presence of PE-g-MAH; thenotched and nonotched impact strength was increased by 324.1% and 485. 4% respectively when the same amount of EPDMwas added in the presence of MAH, PE and Kaolin grafted master botch. The effect of rubber and its content, Kaolin and itskind, and the effect of modifying technology were also studied in this paper. The conclusion was that EPDM, when 10% wasadded, and ultrafine Kaolin were the best modifiers for the toughening.
