LUBRICANT-COOLING LIQUID FOR DIAMOND TREATMENT OF SOFT OPTICAL GLASS Russian patent published in 2002 - IPC

FIELD: technology of glass treatment. SUBSTANCE: invention relates to compositions of lubricant-cooling liquids. The lubricant-cooling liquid has the following composition, wt. %: polyoxyalkylene guanidine salt 0.1-0.3; water, the balance. The following compounds are used as polyoxyalkylene guanidine salt: poly-(4,9- dioxadodecane guanidine) phosphate of the formula: where n = 20-30 or poly-(4,9-dioxadodecane guanidine) chloride of the formula: where n = 20-30 or polyoxyalkylene guanidine phosphate based on polyesteramine with molecular mass 230 Da of the formula: where n = 10-20; x, y, z = 2, 3, 4. Method provides exclusion harmful substances from the sphere of optical production, chemical stability of polymeric component and its constant regeneration by filtering off glass crumble ground off. EFFECT: enhanced output and quality of treated surface, improved ecology of technology, increased life of equipment of lubricant-cooling liquids. 2 cl, 3 tbl, 1 ex
