Abstract

The invention discloses a preparation method of a modified polybutylene succinate composite material for a sensor shell, which comprises the following steps: dispersing water-soluble carbon powder indeionized water, conducting grinding, conducting mixing with an acrylate, a silane coupling agent and water-soluble epoxy resin, putting glass fibers into the mixture for dip dyeing, taking out the glass fibers and conducting drying to obtain glass fibers colored by carbon black; mixing silicon dioxide modified by the silane coupling agent with xylene, conducting stirring and dispersing, adding p-toluenesulfonic acid, conducting heating and refluxing under the protection of nitrogen, adding 2,2-dimethylolpropionic acid, carrying out constant-temperature reaction, carrying out reduced-pressuresuction filtration, and carrying out vacuum drying to obtain hyperbranched polyester grafted silicon dioxide; uniformly mixing epoxy resin, a curing agent and the carbon black colored glass fibers, packing the mixture into a mold, and carrying out mold pressing to obtain a mold pressing material; and putting polybutylene succinate, hyperbranched polyester grafted silicon dioxide, surface chemically modified whiskers and an antioxidant into a device, conducting mixing, and carrying out melt blending on the obtained mixed material and the mold pressing material in a screw extruder to prepare thecomposite material.

Description

technical field [0001] The invention belongs to the field of sensors, and in particular relates to a preparation method of a modified polybutylene succinate composite material for a sensor shell. Background technique [0002] Among biodegradable materials, polybutylene succinate has the advantages of relatively low price, high melting point, and good comprehensive performance, so it has become a research and development hotspot for scientific research institutions and enterprises. Filling modification is a common method for modifying polymer materials, but during the modification process, the improvement of mechanical properties is often accompanied by a significant increase in the processing viscosity of the material, which is not conducive to the processing and production of the material and brings adverse effects. As one of the three major biodegradable materials, polybutylene succinate is more and more favored by people because of its good comprehensive performance. How...
