Description
Известна мастика, используема дл покрыти полов, включающа поливипилацетатную эмульсию с размером частиц 1-4 мк, портландцемент , песок и воду.A known mastic used for floor coatings, comprising a polyvipyl acetate emulsion with a particle size of 1-4 microns, portland cement, sand and water.
Однако в нзвестпой мастике содержитс большое количество воды, влекущее за собой увеличе1П1е пористости и усадки покрыти , а также снижение его прочности.However, in the past paste there is a large amount of water, which entails an increase in porosity and shrinkage of the coating, as well as a decrease in its strength.
Целью изобретени вл етс повышение прочности покрытн , а также улучшение его адгезионных свойств.The aim of the invention is to increase the strength of the coating, as well as the improvement of its adhesive properties.
Это достигаетс тем, что, мастика содержиг следующие компопенты, вес. %:This is achieved by the fact that the mastic contains the following components, weight. %:
Поливинилацетатна эмульси Polyvinyl acetate emulsion
с величиной частиц 0,05-0,4 мк Портландцемент Наполнитель Вода Эмульси имеет в зкость пор дка 240 спз.with a particle size of 0.05-0.4 microns Portland cement Filler Water Emulsion has a viscosity of about 240 centipoise.
Дл изготовлепи эмульсии используют поливиппловый сппрт с эмульгаторами.For the manufacture of emulsions, a poly-hipplite with emulsifiers is used.
Приготавливают мастику путем перемешивани всех вышеуказанных компонентов в смесителе.A paste is prepared by mixing all the above components in a mixer.
Применение тонкодисперсной поливинилацетатной эмульсии обеспечивает рабочую в зкость мастики при водоцементном отношении ,95-1,0, а также способствует повышению механической прочг ости покрыти при увеличении плотности структуры.The use of a finely dispersed polyvinyl acetate emulsion provides a working mastic viscosity at a water-cement ratio of 95-1.0, and also contributes to an increase in the mechanical strength of the coating with an increase in the density of the structure.
Предусматриваетс использовать в мастике портландцемент, пе содержащий активных миперальпых добавок, преимущественно марки «400.It is intended to use Portland cement in the mastic, which does not contain active miperaplyh additives, mainly brand "400.
