Abstract

The invention discloses a rigid plastic casing material. The rigid plastic casing material is prepared from raw materials in parts by weight as follows: 2-3 parts of 8-hydroxyquinoline, 3-4 parts of carbon nano tubes, 40-50 parts of thionyl chloride, 3-5 parts of N,N-dimethylformamide, 100-120 parts of quadrol, 16-20 parts of melamine, 36-40 parts of 35%-37% formalin, 170-200 parts of polyvinyl chloride, 20-30 parts of 75%-80% sulfuric acid, 30-40 parts of 95%-98% nitric acid, 30-40 parts of heavy calcium carbonate, 4-6 parts of aluminum-magnesium silicate, 1-2 parts of lauryl dimethyl amine oxide, 2-3 parts of zinc naphthenate, 14-16 parts of glycerol triacetate, 0.3-1 part of ascorbic acid and 2-4 parts of lithium carbonate. A plastic casing is hard, has high strength and good anti-impact performance and is not prone to damage.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a hard 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 nanotubes and ...
