High-conductivity polystyrene-polyethylene composite conductive material and preparation method thereof

Abstract

The invention discloses a high-conductivity polystyrene-polyethylene composite conductive material and a preparation method thereof, and relates to the field of composite conductive materials, polystyrene, polyethylene, a lubricant, an antioxidant, a flame retardant, a plasticizer and a compatilizer are uniformly mixed and then extruded by a granulator, carbon black is added according to the proportion for granulation, and the high-conductivity polystyrene-polyethylene composite conductive material is obtained. The high-conductivity polystyrene-polyethylene composite conductive material is obtained by sufficiently kneading all the components in a molten state, extruding, cooling and pelletizing, and the problems that resin is influenced by a high-temperature environment and is easy to crack and the product performance is reduced in the using process of an existing composite conductive material, and the flame retardance of the composite conductive material is poor are solved; polystyrene and polyethylene are used as base materials, an antioxidant is added to increase the anti-aging performance, a flame retardant is added to increase the flame retardant performance, and a lubricant and a compatilizer are added to improve the lubricity of the conductive material during extrusion, so that a product with large width is smoothly extruded, and the prepared product is better in uniformity.

Description

technical field [0001] The invention relates to the field of composite conductive materials, in particular to a high-conductivity polystyrene-polyethylene composite conductive material and a preparation method. Background technique [0002] Polymer materials have excellent electrical insulation properties, so they are widely used in various fields of industrial production and life. However, due to the high resistivity of general polymer materials, their products are easily generated and accumulated due to the friction and impact of airflow and liquid flow. Static electricity, which accumulates on the surface of the product may bring difficulties to the molding operation, affect the quality of the product, and also make the surface of the product difficult to clean, and affect the appearance of the assembly and application in an ultra-clean environment, or Noise or clutter is generated during recording and video recording. What is particularly serious is that when the static ...

Problems solved by technology

[0007] (1) After mixing polystyrene, polyethylene, lubricant, antioxidant, flame retardant, plasticizer and compatibilizer, extrude with a granulator, add carbon black to granulate according to the stated ratio, each The components are fully kneaded in the molten state and then extruded and cooled to pelletize to obtain the high-conductivity polystyrene-polyethylene composite conductive material, which solves the problem that the resin is affected by the high temperature environment during the use of the existing composite conductive material. It is easy to crack, reduces product performance, and the flame retardancy of composite conductive materials is poor;
