Abstract

The invention discloses an antistatic plastic shell material. The antistatic plastic shell material is prepared from, by weight, 10-15 parts of tributyl citrate, 3-4 parts of carbon nanotubes, 40-50 parts of thionyl chloride, 3-5 parts of N,N-dimethylformamide, 100-120 parts of ethidene diamine, 16-20 parts of melamine, 36-40 parts of a formaldehyde aqueous solution with the concentration of 35%-37%, 170-200 parts of polyvinyl chloride, 20-30 parts of sulfuric acid with the concentration of 75 wt%-80 wt%, 30-40 parts of nitric acid with the concentration of 95 wt%-98 wt%, 2-3 parts of formamide, 2-3 parts of dodecyl dimethyl betaine, 4-6 parts of fatty acid polyglycol ester, 3-4 parts of ammonium molybdate, 4-7 parts of calcium stearate, 1-2 parts of p-toluene sulfonic acid and 10-14 parts of silica powder. According to the material, by adding dodecyl dimethyl betaine, fatty acid polyglycol ester and the like, the antistatic property of the surface of a plastic shell can be effectively improved, and the use safety is improved.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to an antistatic plastic shell material and a preparation method thereof. Background technique [0002] Carbon nanotubes have excellent mechanical properties and self-lubricating properties. As a filling material, if they can be uniformly dispersed in the polyvinyl chloride matrix and can form good interfacial compatibility with the polyvinyl chloride matrix, they can be used effectively. Improve the mechanical properties and friction properties of polyvinyl chloride matrix. However, due to the large surface energy and specific surface area of ​​carbon nanotubes, carbon nanotubes are easy to aggregate; at the same time, the surface of carbon nanotubes presents a strong non-polarity, making it insoluble in any solvent and polymer. Therefore, in order to improve the dispersion of carbon nanotubes in the polymer matrix and enhance the interfacial compatibility between carbon nanotube...
