| titleOfInvention | There is the preparation method of the cast composite nylon material of high antifriction antiwear upper layer |
| abstract | The invention discloses the preparation method of the cast composite nylon material with high antifriction antiwear upper layer, first, make dispersion suspensoids in proportion by HMPA, ultrafine kaolin and tolylene diisocyanate; Then, add dispersion suspensoids and ptfe micropowder in hexanolactam melt, cause the reaction of caprolactam anionic ring-opening polymerization by sodium hydroxide-tolylene diisocyanate catalytic activation system; Finally, be cast into by reaction mass in the centrifugal rotation mould of preheating insulation under normal pressure, reaction casting liquid is polymerized and after coagulation forming, progressively cooling and demolding, obtains the cast composite nylon material with high antifriction antiwear upper layer.The inner base of the cast composite nylon material prepared by the present invention and outer surface layer have different stuctures and properties, meet for the supporting all kinds of pulleys of Transport Machinery, tackle gear and mining equiment, roller, rope sheave, guide deflection sheave manufacture and service requirements. |
