| titleOfInvention | Improvements in abrasive bodies bonded with synthetic resins |
| abstract | Abrasive bodies, e.g. grinding and snagging wheels, are obtained by bonding abrasive grains with an aromatic amine-aldehyde condensate produced in the presence of strong acid and bonding and hardening the mixture by heating it to 130-190 DEG C. in presence of a melamine hydrohalide. There are specified: aromatic amines-aniline, m - phenylenediamine, m - toluidine, diamino diphenyl methane; melamine hydrohalides-the mono, di or tri hydrochlorides or bromides; abrasives-alumina, emery, corundum, silicon carbide, quartz, diamonds; acids-hydriodic, hydrochloric, phosphoric, tri and dichloro-acetic, maleic, oxalic, picric, sulphuric acids. The grains may be plasticised with furfural. Aniline is dissolved in hydrochloric acid and, after standing, the solution is neutralized with sodium hydroxide. The precipitated resin is washed, filtered, dried, and powdered. The powder is then mixed with melamine trihydrochloride and alumina grit and the mixture moulded and cured at 160 DEG C. |
