Embodiment Construction

[0019] A nylon blend plastic shell material, which is composed of the following parts by weight:

[0020] Melamine 16, ethylene diamine 100, polyisoprene 5, potassium sodium tartrate 1, carbon nanotubes 3, thionyl chloride 40, N, N dimethylformamide 3, polyvinyl chloride 160, 75wt% sulfuric acid 20. 95wt% nitric acid 30, nylon PA6640, dioctyl sebacate 10, dodecyl mercaptan 3, polyamide wax powder 6, quartz sand 30, 35% formaldehyde aqueous solution 36.

[0021] A method for preparing the nylon blended plastic shell material includes the following steps:

[0022] (1) Mix the above 75wt% sulfuric acid and 95wt% nitric acid, stir evenly, add carbon nanotubes, oscillate ultrasonically for 2 hours in a constant temperature water bath at 50°C, add deionized water 8 times the weight of the system to dilute, and leave to stand in the warm After the solution is stratified, the supernatant is discarded, the lower solution is suction filtered, and the filter cake is vacuum dried at 80°C for 10...

Abstract

The invention discloses a nylon blended plastic casing material. The material is prepared from raw materials in parts by weight as follows: 16-20 parts of melamine, 100-120 parts of ethylenediamine, 5-7 parts of polyisoprene, 1-2 parts of sodium potassium tartrate tetrahydrate, 3-4 parts of carbon nanotubes, 40-50 parts of thionyl chloride, 3-5 parts of N,N-dimethylformamide, 160-210 parts of polyvinyl chloride, 20-30 parts of 75wt%-80wt% sulfuric acid, 30-40 parts of 95wt%-98wt% nitric acid, 40-50 parts of nylon PA66, 10-13 parts of dioctyl sebacate, 3-4 parts of lauryl mercaptan, 6-10 parts of polyamide wax micro-powder, 30-40 parts of quartz sand and 36-40 parts of a 35%-37% formalin. According to a plastic casing, polyvinyl chloride and nylon are blended, so that the surface hardness, resistance, waterproof performance and acid and alkali resistance of the finished casing product are further improved.

Description

Technical field [0001] The invention relates to the field of plastic production, in particular to a nylon blend plastic shell material and a preparation method thereof. Background technique [0002] Carbon nanotubes have excellent mechanical properties and self-lubricating properties. As a filler, if they can be uniformly dispersed in the polyvinyl chloride body, and can form good interface compatibility with the polyvinyl chloride body, it can be effectively Improve the mechanical properties and friction properties of polyvinyl chloride. However, due to the large surface energy and specific surface area of ​​carbon nanotubes, the carbon nanotubes are easy to agglomerate; at the same time, the surface of carbon nanotubes presents a strong non-polarity, making them insoluble in any solvents and polymers. Therefore, in order to improve the dispersibility of carbon nanotubes in the polymer matrix and enhance the interface compatibility between carbon nanotubes and the polymer matri...
