Toughened antistatic dual-functional plastic master batch for direct injection molding and preparation method thereof

Abstract

The invention belongs to the technical field of plastic modification and processing and in particular relates to toughened antistatic dual-functional plastic master batch capable of being directly used for injection molding of a plastic product and a preparation method of the toughened antistatic dual-functional plastic master batch. The dual-functional plastic master batch is prepared from the following components in percentage by mass: 75.0 to 83.0 weight percent of a vinyl elastic ionomer, 5.0 to 10.0 weight percent of a three-arm telechelic ionomer, 3.0 to 6.0 weight percent of polyvinylpyrrolidone, 5.0 to 10.0 weight percent of carrier resin, 0.03 to 0.08 weight percent of a micro-crosslinking initiator, 0.3 to 0.5 weight percent of dispersant and 0.3 to 0.5 weight percent of a lubricant, wherein the polyvinylpyrrolidone is medium and low molecular weight N-polyvinylpyrrolidone with the K value of 25 to 60. Compared with traditional plastic master batch, the plastic master batch prepared by the invention not only has good toughening and antistatic dual-functional modification effects, but also has the properties of easiness for dispersion and easiness for processing; the toughened antistatic dual-functional plastic master batch can be simply mixed with modified plastic according to a ratio and then a mixture is directly used for injection molding processing of the plasticproduct; and a good modification effect is obtained.

Description

technical field [0001] The invention belongs to the technical field of plastic modification and processing, and in particular relates to a toughened and antistatic dual-functional plastic masterbatch which can be directly applied to injection molding of plastic products and a preparation method thereof. Background technique [0002] Using twin-screw extruder to implement melt blending extrusion method is an important technical development direction in the field of high-performance and multi-functional modification processing of thermoplastics. The high-efficiency and excellent mixing performance of twin-screw extruder can be used for general and Continuous melt blending of engineering plastics and various plastic modification additives and extrusion granulation, the modified special materials prepared are then used in injection or extrusion molding processing, which can not only effectively improve the strength, toughness, Mechanical properties such as stiffness can also end...

Problems solved by technology

However, it is difficult to directly apply elastic ionomers to the toughening modification in the plastic injection molding process. The “sea-island” phase structure with regular shape can be obtained by cutting action, which leads to the decrease of toughening effect.
