Problems solved by technology

The addition of conventional toughening agents to stably realize the super-toughening of nylon requires the addition of more than 15wt% of toughening agents, but the grafts made by conventional methods have a high degree of crosslinking, poor fluidity, and are not easy to disperse. The processability of toughened nylon has a great impact. In addition, since POE, EPDM, etc. are composed of flexible chain segments, a higher addition amount will lead to a significant loss of nylon tensile strength

Abstract

The present invention relates to a polyolefin elastomer compound grafted with nanoparticles and maleic anhydride and its preparation; the polyolefin elastomer comprises POE, POE-nanoparticle functionalized masterbatch, maleic anhydride Anhydrides, peroxides, crosslinking inhibitors, antioxidants and lubricants. The preparation method of the polyolefin elastomer is: after mixing the POE of the polyolefin elastomer and the functionalized masterbatch of POE-nano particles uniformly, adding from the main feeding port of the twin-screw extruder, adding maleic anhydride, After mixing the peroxide, cross-linking inhibitor, antioxidant and lubricant, they are added from the first side feed port, and ultrasonic treatment is performed while blending to obtain the polyolefin elastomer. The advantages of the present invention are: 1. The toughening efficiency of polyolefin elastomer in toughened nylon is improved by introducing composite grafting of nano rigid particles; 2. The industrialization of rigid particle toughening is realized through ultrasonic technology and step-by-step processing Production.

Description

technical field [0001] The invention belongs to the field of macromolecules, and relates to a polyolefin elastomer compound-grafted with nanoparticles and maleic anhydride and a preparation method thereof. Background technique [0002] Nylon has good comprehensive mechanical properties, and is wear-resistant and oil-resistant. In recent years, it has been ranking first among the five major engineering plastics. There are high requirements for toughness in many fields. It is of great theoretical and practical significance to study the toughening efficiency of tougheners and take into account other properties. [0003] The toughening agent for nylon is generally POE-g-MAH or EPDM-g-MAH. The addition of conventional toughening agents to stably realize the super-toughening of nylon requires the addition of more than 15wt% of toughening agents, but the grafts made by conventional methods have a high degree of crosslinking, poor fluidity, and are not easy to disperse. The proces...
