Abstract

FIELD: protective coatings. SUBSTANCE: invention relates to compositions applied for finishing concrete and stucco surfaces to be protected against radiations. Known composition based on clay and optical glass wastes manifest unsatisfactory protective characteristics. More acceptable ones are achieved with composition containing (in wt %): liquid glass, 50.0- 54.1; sodium silica-fluoride, 5.0-5.4; optical glass wastes, 13.5- 25.7; barium sulfate, 12.5-16.3; and magnetite, 4.0-13.5. EFFECT: improved protective characteristics.

Description

Изобретение относится к составам покрытий, применяемых для отделки бетонных и штукатурных поверхностей, подлежащих защите от излучения. The invention relates to coating compositions used for finishing concrete and plaster surfaces to be protected from radiation.

Известен состав, включающий (в мас.) полиметилфенилсилоксан 50-79, тетроэтоксисилан 20-42, метилфенилсиликонат натрия 1-8 [1]
Наиболее близким по технической сущности и достигаемому результату является состав, включающий жидкое стекло, кремнефтористый натрий, хромит [2]
Недостатком указанных составов является низкая прочность сцепления с основной конструкцией, высокое значение предельного напряжения сдвига, что затрудняет нанесение композиции на защищаемую конструкцию.
A known composition, including (in wt.) Polymethylphenylsiloxane 50-79, tetroethoxysilane 20-42, sodium methylphenylsiliconate 1-8 [1]
The closest in technical essence and the achieved result is a composition including liquid glass, sodium silicofluoride, chromite [2]
The disadvantage of these compositions is the low adhesion to the main structure, the high value of the ultimate shear stress, which makes it difficult to apply the composition to the protected structure.

Цель изобретения повышение прочности сцепления, снижение предельного напряжения сдвига при сохранении защитных свойств покрытия. The purpose of the invention is to increase the adhesion strength, reduce the ultimate shear stress while maintaining the protective properties of the coating.

Цель достигается тем, что композиция для защитного покрытия, включающая связующее жидкое стекло, отвердитель кремнефтористый натрий и наполнитель, содержащий магнетит, в качестве наполнителя она содержит смесь магнетита, отходов оптического стекла и сернокислого бария при следующем соотношении компонентов, мас. жидкое стекло 50-54,1, кремнефтористый натрий 5-5,4, магнетит 4-13,5, отходы оптического стекла 13,5-25,7, сернокислый барий 12,5-16,3. The goal is achieved in that the composition for a protective coating comprising a binder liquid glass, a hardener sodium silicofluoride and a filler containing magnetite, as a filler it contains a mixture of magnetite, waste optical glass and barium sulfate in the following ratio, wt. liquid glass 50-54.1, sodium silicofluoride 5-5.4, magnetite 4-13.5, optical glass waste 13.5-25.7, barium sulfate 12.5-16.3.

Отходы оптического стекла имеют следующий химический состав, мас. Na2O 0,5; K2O 1,27; Al2O3 0,3; PbO 70,93; SiO2 27,27. Линейный коэффициент поглощения гамма-лучей при энергии гамма-квантов от 0,5 до 3 МэВ составляет соответственно 0,8-0,24 см-1. Плотность отходов оптического стекла составляет до 4,5 г/см3.Optical glass waste has the following chemical composition, wt. Na 2 O 0.5; K 2 O 1.27; Al 2 O 3 0.3; PbO 70.93; SiO 2 27.27. The linear absorption coefficient of gamma rays when the energy of gamma rays from 0.5 to 3 MeV is respectively 0.8-0.24 cm -1 . The density of the waste optical glass is up to 4.5 g / cm 3 .

Технология приготовления композиции следующая. В барабан лопаткой мешалки загружают последовательно жидкое стекло, кремнефтористый натрий, перемешивают, после чего добавляют отходы оптического стекла, сернокислый барий и магнетит и вновь перемешивают. Конкретные примеры составов и их свойства приведены в табл. 1, 2. The technology for preparing the composition is as follows. Liquid glass, sodium silicofluoride are sequentially loaded into the drum with a stirrer blade, mixed, then optical glass wastes, barium sulfate and magnetite are added and mixed again. Specific examples of compositions and their properties are given in table. 12.

Линейный коэффициент ослабления определяли при облучении от моноэнергий мелкого источника Cs137. Эквивалентная толщина пленки из алюминия определялась на аппарате РУП-150 при напряжении U=150 кВ.The linear attenuation coefficient was determined by irradiation from the monoenergies of a shallow source of Cs 137 . The equivalent thickness of the aluminum film was determined on an RUP-150 apparatus at a voltage of U = 150 kV.
