Abstract

The invention discloses a rare earth plastic shell material. The rare earth plastic shell material is prepared from the following raw materials in parts by weight: 0.1 to 0.2 part of cerium oxide, 0.1 to 0.2 part of lanthanum citrate, 3 to 4 parts of carbon nanotubes, 40 to 50 parts of thionyl chloride, 3 to 5 parts of N,N-dimethylformamide, 100 to 120 parts of ethylenediamine, 16 to 20 parts of melamine, 36 to 40 parts of 35 to 37% formaldehyde aqueous solution, 170 to 200 parts of polyvinyl chloride, 20 to 30 parts of 75 to 80 wt% sulfuric acid, 30 to 40 parts of 95 to 98wt% nitric acid, 2 to 3 parts of sodium carboxymethylcellulose, 4 to 7 parts of anhydrous calcium chloride, 30 to 40 parts of attapulgite, 2 to 3 parts of dimethylethanolamine and 10 to 13 parts of octyl epoxy stearate. According to the rare earth plastic shell material, the cerium oxide and the lanthanum citrate are added, so that the surface strength of a finished plastic shell product can be effectively increased, and the weather resistance is increased.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a rare earth 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 nanotube...
