Compounds of monolithic floors
A new type of adhesive composition based on kumaron resins for gluing alkyd linoleum is developed by the Kyiv branch of VNIInsm.
To replace scarce plasticizers, reducing the cost and improvement of the quality of these mastics, plasticizers based on the product of the processing of puff oil – cheese and cubic residues of the SZK. Such a replacement of a scarce plasticizer in adhesive mastics will give an economic effect of about 250 thousand. rub. per year with the annual issue of mastic 1 thousand. T.
Seamless floors are currently widespread in construction practice using OSB plates. There is a tendency to improve seamless floors through the widespread use of polymeric materials, as well as the use of these sexes not only in industrial, but also in residential buildings. VNIINSMEM has developed compounds of monolithic mastic and polymer -cement coatings for floors based on polyvinino acetate emulsion (elastic and hard floors), epoxy resin and funeral polymers. The cost of such monolithic coatings ranges from 1 from 3 to 7.5 rubles2 depending on the composition.
High physico-mechanical and operational indicators are possessed by polyester compositions for bulk covers developed by the Institute of Nimosstroy. When testing at industrial and civil construction facilities, they showed reliability in operation. The cost of 1 m2 of polyester coating is 4.75 rubles. in construction conditions and 4.2 rubles. – In the factory.
In order to reduce internal stresses in polyester mastics, it was proposed to modify them with carboxylate rubber of SKD-1B, introduced into polyester resin during its manufacturing in the form of a solution in a monomer. At the same time, along with a decrease in internal stresses, the water resistance of polyester mastics increases.
Compositions of monolithic floors based on copolymers of the Indden-kumaron resin (ICAS-1), which have high chemical resistance, have been developed by the VNIITVOLOSISION Institute.
