Abstract
Изобретение относитс к составам смазок дл металлических форм при производстве железобетонных и бетонных изделий. Цель изобретени - снижение адгезии бетона к форме, улучшение качества бетонной поверхности, упрощение приготовлени смазки и утилизаци отхода. Смазка содержит, мас.%: нефт ной масл ный эмульсол 14-20, побочный продукт очистки изопренового каучука содержит, мас.%: диоксановые спирты 72,7-74,34, метилбутилдиол 2,18-6,83, диметилдиоксан 0,5-0,66, пирановый спирт 1,02-1,14, невозгон емые т желые фракции нефти 14,92-16,0 и примеси остальное. Напр жение отрыва бетона от формы при распалубке составл ет 2-4.10-4 МПа, поверхностна пористость бетона 0,15-0,17%. 2 табл.This invention relates to lubricant formulations for metal molds in the manufacture of reinforced concrete and concrete products. The purpose of the invention is to reduce the adhesion of concrete to form, to improve the quality of the concrete surface, to simplify the preparation of the lubricant and to recycle the waste. The lubricant contains, in wt.%: Petroleum oil emulsol 14-20, a by-product of the purification of isoprene rubber contains, wt%: dioxane alcohols 72.7-74.34, methylbutyldiol 2.18-6.83, dimethyl dioxane 0.5 -0.66, pyran alcohol 1.02-1.14, non-permeable heavy oil fractions 14.92-16.0, and impurities the rest. The strain-off potential of the concrete from the mold during stripping is 2-4 . 10 -4 MPa, the surface porosity of concrete is 0.15-0.17%. 2 tab.
Description
Изобретение относитс к составам смазок дл металлических форм при производстве железобетонных и бетонных изделий .This invention relates to lubricant formulations for metal molds in the manufacture of reinforced concrete and concrete products.

Пример. Смазку готов т путем перемешивани компонентов, вз тых в заданном соотношении .Example. The lubricant is prepared by mixing the components, taken in a predetermined ratio.
В табл. 1 приведены составы смазок (составы смазок 2 - 4 предлагае.мые, и 5 - запредельные значени содержани компонентов ), в табл. 2 - результаты испытаний.In tab. Table 1 lists the lubricant compositions (lubricant compositions 2-4 are suggested, and 5 are prohibitive values of the components), in table. 2 - test results.
