▎ 摘　　要

NOVELTY - A corrosion-resistant polyoxymethylene carbon fiber reinforced composite material contains 90-100 pts. wt. polyoxymethylene, 10-30 pts. wt. carbon fiber, 2-4 pts. wt. dicyandiamide, 0.4-0.8 pts. wt. N,N-ethylenebis stearamide, 4-5 pts. wt. diatomaceous earth, 0.4-0.7 pts. wt. calcium stearate, 0.3-0.5 pts. wt. 3,5-bis(1,1-dimethylethyl)-4-hydroxybenzenepropanoic acid octadecyl ester, 4-6 pts. wt. glass beads powder, 0.3-0.6 pts. wt. KH-550 (RTM: Silane coupling agent), 2-4 pts. wt. graphene oxide, and 2-3 pts. wt. nano-silica. USE - Corrosion-resistant polyoxymethylene carbon fiber reinforced composite material (claimed). ADVANTAGE - The polyoxymethylene carbon fiber reinforced composite material has excellent corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of corrosion-resistant polyoxymethylene carbon fiber reinforced composite material, which involves adding polyoxymethylene, carbon fiber and 3,5-bis(1,1-dimethylethyl)-4-hydroxybenzenepropanoic acid octadecyl ester to a high speed mixer, uniformly mixing, stirring the mixture at 70-80 degrees C and then drying for 2-3 hours under vacuum, adding nano-silica to the mixture and then sintering at 400-450 degrees C for 2-3 hours under vacuum, adding graphene oxide and anhydrous ethanol to the mixture and then stirring for 5-10 minutes, adding diatomaceous earth and glass beads powder to the mixture and then continuously dispersing for 20-30 minutes, filtering the mixture and then washing using distilled water, drying the mixture and then precipitating, adding KH-550 (RTM: Silane coupling agent) and N-ethylenebis stearamide to the mixture and then mixing, grinding the mixture, adding chopped carbon fiber to the mixture and then preheating, adding paraformaldehyde to the mixture and then placing in a twin screw extruder, extruding the mixture and then cooling, granulating the mixture and then vacuum drying at 70-80 degrees C for 2-3 hours, heating the mixture at 150-180 degrees C and then rapidly cooling, placing the mixture in an injection molding machine and then molding at 180-190 degrees C under a pressure of 50-60 MPa and a speed of 55-60 mm/seconds, holding the mixture for 15-20 seconds, and molding at 70-80 degrees C.
