NOVELTY - High-strength super wear-resistant MC nylon composite material comprises 80-120 pts. wt. caprolactam, 2-5 pts. wt. ABS powder, 0.1-0 .3 pts. wt. metal salt solution, 0.5-1.5 pts. wt. catalyst, 1-4 pts. wt. modified lubricant, 1-3 pts. wt. activator, 0.1-0.4 pts. wt. carboxy-terminated polysilicoxane; the ABS powder is 300-600 mesh; the metal salt solution is 0.3-0.6 mol/l zinc chloride or copper chloride aqueous solution; the catalyst is hydrogen sodium or sodium methoxide; the modified lubricant is prepared from cerium dioxide, mica powder, tung oil, and graphene oxide fibers; the active agent is N-caproyl caprolactam or 2,4 toluene diisocyanate. USE - The casting nylon composite material is useful in machinery, textile, transportation, petrochemical and metallurgy. ADVANTAGE - The high-strength ultra-wear-resistant MC nylon composite material has excellent strength, wear resistance and hydrophobic performance, and the application range is wider. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing a high-strength super wear-resistant MC nylon composite material, comprising (i) adding cerium oxide, graphene oxide fiber, mica powder and isopropanol into the reaction vessel and stirring for 20-50 minutes, adding tung oil, and ultrasonically dispersing at 40-60°C for 1-3 hours to mix evenly, washing and drying by centrifugation to obtain product A; low-temperature plasma treatment to obtain a modified lubricant; (ii) heating and melting caprolactam under the protection of nitrogen according to the weight ratio, then adding ABS powder, heating and melting; then adding metal salt solution, and stirring to react; (iii) passing nitrogen to release vacuum, under normal pressure, adding catalyst in step (ii) by weight ratio, continuing vacuuming; (iv) feeding nitrogen to remove vacuum, adding modified lubricant and activator, stirring evenly with carboxy-terminated polysiloxane, pouring it into a pre-heated mold, insulating for reaction, cooling to room temperature and demolding.
