LUBRICANT COMPOSITIONS FOR OILING SHAPES FOR PRODUCING WHITE GAS-CONCRETE BUILDING ELEMENTS

Lubricant compsn. for white, gas-concrete walling and buildings element manufacturing patterns comprises (all wt.%'s): (a) 38-75 refined mineral oil of 30 - 50 mmsq/s viscosity at 100 deg.C, not greater than -5 deg.C congealing pt., of an acid value less than 0.1 mgKOH/g and having an open-cup flash pt. not less than 240 deg.C. (b) 23 - 60 refined mineral oil of 61.2 - 748 mmsq/s viscosity at 40 deg.C; not greater than -10 deg.C congealing pt.; less than 0.1 mgKOH/g acid value and at least 190 deg.C open cup flash pt. (C) 1.0 - 2.0 oxidised microcrystalline paraffin wax of 400 - 700 average mol. wt., 15 - 40 mgKOH/g acid value and 60 - 70 deg. drop pt. (d) multifunctional inhibitor of tackifying, corrosion preventing, simultaneous rust converting, E.P. and wear-resistant characteristics, contg. 100 pts. wt. alkali-sulphonates in aq. soln. These sulphonates are by-prods. of acid refining of mineral oils and of mineral oil prods. of 300 - 700 average mol. wt. and 30 - 60 mgKOH/g acid value; 50 - 200 pts. wt. of refined hydrocarbon prods. of 60 - 75 mmsq/s viscosity at 40 deg.C; 0.5 - 5 pts. wt. phosphoric acid monoester with higher (10 - 28C) alcohols, as catalyst; 6 - 35 pts. wt. 8 - 12 alkylamine, arylamine, aralkyl-amine, cyclo-hexyl-amine, di:cyclo-hexyl-amine, mono:-, di:- and/or tri:-ethanolamine; and 5 - 20 pts. wt. phosphoric and/or tannic acid.
