Abstract

The invention discloses an anti-static high-tenacity PP / PA6 composite. A preparation method of the anti-static high-tenacity PP / PA6 composite comprises the steps that a synergic compatibilization and toughening agent is added into a PP and PA6 composite, melt blending injection molding is adopted for obtaining the PP / PA6 composite, wherein in the mixed system, the total mass percentage of PP and PA6 is 80-95%, the mass percentage of the synergic compatibilization and toughening agent is 5-20%, the weight ratio of PA6 to PP is 1:9-2:3, the synergic compatibilization and toughening agent is prepared from 4.9-15% of ionic liquid and 0.1-5% of fumed nano-silica, positive ions in the ionic liquid are imidazoles or pyridines, and the negative ions are chloride ions. The elongation at break of the anti-static high-tenacity PP / PA6 composite prepared through the method is 250-800%, and the surface resistance of the anti-static high-tenacity PP / PA6 composite is 105-108 omega.

Description

Technical field [0001] The invention belongs to the field of polymer materials, and specifically relates to a preparation method of a method for synergistic compatibilization and toughening PP / PA6 composite material. Background technique [0002] Blending modification is a simple and effective modification method. Blending PP with other plastics can prepare polymer alloys with the properties of these polymers. However, PA6 is a strongly polar polymer, and PP is a weakly polar polymer. The solubility parameters of the two are quite different and they are not thermodynamically compatible. Therefore, a simple blend of PP and PA6 exists. This is the disadvantage of poor compatibility. [0003] At present, the commonly used compatibilizers are divided into three main categories according to the main chain structure: the first category is the graft copolymer of rubber (such as ethylene propylene rubber) and polar monomer (such as maleic anhydride); the second is Graft copolymers of PP ...
