Abstract

The invention discloses a flame retardant plastic shell material. The flame retardant plastic shell material is prepared from, by weight, 1-2 parts of fatty acid diethanol amide, 3-4 parts of carbon nano tubes, 40-50 parts of thionyl chloride, 3-5 parts of N-dimethyl formamide, 100-120 parts of ethylenediamine, 16-20 parts of melamine, 36-40 parts of a 35-37% formaldehyde solution, 170-200 parts of polyvinyl chloride, 20-30 parts of 75-80wt% sulfuric acid, 30-40 parts of 95-98wt% nitric acid, 30-40 parts of talcum powder, 10-13 parts of tributyl citrate, 3-4 parts of pentaerythritol, 4-6 parts of ammonium polyphosphate, 10-12 parts of polytetrafluoroethylene wax, 3-4 parts of allyl polyethylene glycol and 1-2 parts of ferrous sulfate. The talcum powder, the ammonium polyphosphate and the like are added into the flame retardant plastic shell material, the flame retardant performance of finished plastic is effectively improved, and the use safety is improved.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a flame-retardant plastic casing 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 nan...
