Description

Изобретение касается составов сухих сырьевых смесей для приготовления замазок, которые могут быть использованы для выравнивания поверхностей бетонных, асбестоцементных изделий, заполнения дефектов.The invention relates to the composition of dry raw mixes for the preparation of putties, which can be used for leveling the surfaces of concrete, asbestos-cement products, filling defects.

Известно использование асбеста низких сортов в сочетании с портландцементом при его количестве от 0-400 мас.ч. на 100 мас.ч. портландцемента в сухой смеси, используемой путем затворения ее водой [1].It is known to use low grade asbestos in combination with Portland cement at an amount of 0-400 parts by weight. per 100 parts by weight Portland cement in a dry mixture used by mixing it with water [1].

Известна сырьевая смесь для приготовления замазки, содержащая, мас. %: портландцемент 30-35; асбест 7 сорта 10-15; карбоксиметилцеллюлоза 0,2-0,3; молотый до прохождения через сито 014 кварцевый песок 27,7-31,7; вода 23-27 [2].Known raw mixture for the preparation of putty, containing, by weight. %: Portland cement 30-35; asbestos grade 7 10-15; carboxymethyl cellulose 0.2-0.3; quartz sand 27.7-31.7 ground before passing through a sieve 014; water 23-27 [2].

Задача изобретения состоит в уменьшении расхода вяжущего в составе сухой сырьевой смеси для приготовлении замазки, снижении водопоглощения замазки, расширении ассортимента замазок.The objective of the invention is to reduce the consumption of the binder in the composition of the dry raw mixture for the preparation of the putty, to reduce the water absorption of the putty, to expand the range of putties.

Технический результат достигается тем, что сухая сырьевая смесь для приготовления замазки, содержащая портландцемент, кварцевый песок, асбест 7 сорта, дополнительно включает измельченные до прохождения через сито 008 молотое кварцевое стекло и полиакрилат натрия при следующем соотношении компонентов, мас.ч: портландцемент 100; кварцевый песок 210-220; асбест 7 сорта 60-70; указанное кварцевое стекло 70-75; полиакрилат натрия 0,1-0,4.The technical result is achieved by the fact that the dry raw mixture for the preparation of putty, containing Portland cement, quartz sand, grade 7 asbestos, additionally includes ground quartz glass and sodium polyacrylate crushed before passing through a sieve 008 with the following ratio of components, wt.h: Portland cement 100; quartz sand 210-220; asbestos grade 7 60-70; the specified quartz glass 70-75; sodium polyacrylate 0.1-0.4.

Полиакрилат натрия - натриевая соль полиакриловой кислоты, имеет химическую формулу вида [-CH2-CH(COONa)-]n. Представляет собой анионный полиэлектролит с отрицательно заряженной карбоксильной группой в основной цепи, выпускается промышленностью в гранулах.Sodium polyacrylate - sodium salt of polyacrylic acid, has a chemical formula of the form [-CH2-CH (COONa) -] n. It is an anionic polyelectrolyte with a negatively charged carboxyl group in the main chain, produced by the industry in granules.

В таблице приведены составы сырьевой смеси для приготовления замазки.The table shows the composition of the raw mix for the preparation of putty.

Все компоненты дозируют в требуемых количествах и перемешивают. Сухую сырьевую смесь дозируют в водонепроницаемые пакеты, мешки, бочки. Перед использованием в смесь добавляют воду в количестве, необходимом до придания ей рабочей консистенции и выдерживают в течение 15-30 мин. при комнатной температуре. Полученную замазку используют по назначению.All components are dosed in the required quantities and mixed. The dry raw mixture is dosed into waterproof bags, bags, barrels. Before use, water is added to the mixture in the amount necessary to give it a working consistency and kept for 15-30 minutes. at room temperature. The resulting putty is used for its intended purpose.
