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...
