Color-matching conductive polysulfone material and preparation method thereof

Abstract

The invention discloses a color-matching conductive polysulfone material and a preparation method thereof. The color-matching conductive polysulfone material is composed of the following raw materialsby weight: 43-88.8 parts of polysulfone as a main material, 1-5 parts of nano SiO2 as an auxiliary material, 10-50 parts of nanometer conductive modified TiO2 as an auxiliary material, and 0.2-2 parts of a lubricant as an auxiliary material. The nano conductive modified TiO2 modified PSU material disclosed by the invention has good conductivity, ultrahigh temperature resistance, freely selectablecolors and good warping resistance flatness, and can meet the increasingly developed complex electronic element processability.

Description

technical field [0001] The invention relates to composite materials, in particular to a color-matching conductive polysulfone material and a preparation method for the conductive polysulfone material. Background technique [0002] With the development of the electronic information industry, especially the arrival of the 5G era, the requirements of electronic products for electronic components are constantly increasing, and the temperature of high-temperature processing of molding originals is getting higher and higher, which prompts the need to continuously upgrade the trays containing electronic components and improve high-temperature stability. and product color distinction. [0003] The requirements for electronic component trays are as follows: 1) Conductive and antistatic, the surface resistance is generally required to be 1.0E+6Ω~1.0E+10Ω; 2) Flat warpage, the warpage is required to be less than 0.5mm, and some precision parts require higher requirements ; 3) High tem...

Problems solved by technology

[0005] There are many conductive fillers for plastics, such as carbon fiber, carbon black, metal, graphite, particle type antistatic agent, conductive plastics containing conductive groups, etc., but these filling materials are purely in some defects, carbon fiber, carbon black, Although carbon nanotubes and graphite products can withstand high temperatures, the product color can only be black. Although particle-type antistatic agents and conductive plastics containing conductive groups can freely choose colors, these materials are not resistant to high temperatures and cannot be used in special engineering plastics middle
