摘　　要：对废旧尼龙6(PA6)渔网进行分级回收,采用玻璃纤维(GF)、马来酸酐接枝乙烯-辛烯共聚物(POE-g-MAH)和硅烷偶联剂(KH550)对其进行改性。结果表明:加入GF可以提升再生料的缺口冲击强度、弯曲模量等力学性能,但会降低其熔体流动速率(MFR);当GF质量分数为30.00%时,随着POE-g-MAH用量的增加,3种再生料的缺口冲击强度均逐渐升高,弯曲模量均先升高后降低,均在POE-g-MAH质量分数为5.00%时达到最大值;当GF,POE-g-MAH,KH550的质量分数分别为30.00%,5.00%,0.25%时,一级品和二级品的再生料的焊接强度均超过54.0 MPa,满足制品焊接要求。The waste nylon 6(PA6)fishing nets were graded and recycled,and modified with glass fiber(GF),maleic anhydride grafted ethylene octene copolymer(POE-g-MAH)and silane coupling agent(KH550).The results show that the addition of GF can improve mechanical properties of recycled materials such as notch impact strength and flexural modulus,but it will reduce melt flow rate(MFR).When the mass fraction of GF is 30.00%,with the increase of POE-g-MAH dosage,the notch impact strength of the three recycled materials gradually increases,and the bending modulus first increases and then decreases,reaching the maximum value when the POE-g-MAH mass fraction is 5.00%.When the mass fractions of GF,POE-g-MAH,and KH550 are 30.00%,5.00%and 0.25%respectively,the welding strength of the recycled materials for the first and second grade products exceeds 54.0 MPa,meeting the welding requirements of the product.
