Изобретение относитс к производству смазок дл металлических форм и найдет применение при изготовлении бетонных изделий.The invention relates to the production of lubricants for metal molds and will find application in the manufacture of concrete products.
Известны различные составы смазок дл металлических форм в производстве бетонных изделий , например нефт ное смазочное масло с дисперсной добавкой 1. Недостатком известных смазок вл етс повышенна адгези бетона к формам, что ухудшает качество поверхности изделий и вынуждает проводить операцию чистки форм.Various formulations of lubricants for metal molds are known in the manufacture of concrete products, for example petroleum lubricating oil with dispersed additive 1. A disadvantage of the known lubricants is the increased adhesion of concrete to the molds, which degrades the surface quality of the products and forces the cleaning of the molds to take place.
Наиболее близкой по составу из известных смазок вл етс смазка, состо ща из минерального масла 97,0-99,99% и алифатической сс-оксикислоты в количестве 0,01-3,0% 2. Однако така смазка не в достаточной степени снижает адгезию бетонных изделий к форме , кроме того, стоимость алифатических ос-оксикислот относительно высока.The closest in composition of known lubricants is a lubricant consisting of mineral oil 97.0-99.99% and aliphatic cc-hydroxy acid in an amount of 0.01-3.0% 2. However, this lubricant does not sufficiently reduce adhesion concrete products to the form, in addition, the cost of aliphatic o-hydroxy acids is relatively high.
С целью снижени адгезии бетона к форме предлагаема смазка содержит в качестве добавки а-дикарбоновую кислоту при следующем соотношении компонентов, вес. %: Минеральное масло98,0-99.9In order to reduce the adhesion of concrete to the form of the proposed lubricant contains as an additive a-dicarboxylic acid in the following ratio of components, weight. %: Mineral oil98,0-99.9
сс-Дикарбонова кислота0 ,1-2.0ss-dicarboxylic acid0, 1-2.0
В предложенной смазке масло гидрофобизирует поверхность формы, а а-дикарбонова кислота реагирует со свободной известью вIn the proposed lubricant, the oil hydrophobizes the surface of the form, and α-dicarboxylic acid reacts with free lime in
поверхностном слое бетона с образованием нерастворимых продуктов. Нримеры состава предложенной смазки вес. % :the surface layer of concrete with the formation of insoluble products. The examples of the composition of the proposed lubricant weight. %:

Моторное масло99,899,9Engine oil99,899,9
Щавелева кислота0,20,1Oxalic acid0,20,1
Смазку готов т следующим образом.The lubricant is prepared as follows.
В моторное масло ввод т щавелевую кислоту и перемешивают смесь в течение 3 ч. Полученную смазку нанос т на поверхность формы , в которой обычным путем изготавливают изделие марки 350. После пропаривани изделие легко отдел ют от формы. Величина адгезии достигает 0,025-0,01 кг/см.Oxalic acid is injected into the engine oil and the mixture is stirred for 3 hours. The resulting lubricant is applied to the surface of the mold, in which a brand 350 product is made in the usual way. After steaming, the product is easily separated from the mold. The value of adhesion reaches 0,025-0,01 kg / cm.
Поверхность формы после 10 циклов формовки не требует очистки.The surface of the mold after 10 molding cycles does not require cleaning.
При применении предлагаемой смазки практически исключаетс операци чистки форм и уменьшаетс пористость поверхности изделий.When applying the proposed lubricant, the operation of cleaning the molds is practically eliminated and the porosity of the surface of the products is reduced.
