DOUBLE POLYCYLACATE OF ALKALI METAL AND ORGANIC BASE Russian patent published in 2019 - IPC C08G77/02 C01B33/32 

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry of silicates. Disclosed is a double polysilicate of an alkali metal and an organic base of formula (I) (4-12)SiO₂∙M₂O∙(0.5-0.05)(N_1-2R₄^1,2,3,4)₂O∙(10-60)H₂O, where M is an alkali metal cation, N_1-2R₄^1,2,3,4 – organic base – polymer based on oxyalkylated amine or diamine. Disclosed double polysilicate is in form of particles with specific surface area of 340–740 m²/g; surface of particles contains polycation of organic base in amount of 0.1–0.2 nitrogen functional groups per 10 nm². Obtained double polysilicates have characteristic absorption bands of infrared spectrum in regions of 1,026–1,121 cm^-1 and 1,634–1,651 cm^-1.

EFFECT: disclosed double polysilicate can be obtained from available crude components and can be used as binder for producing thin coatings on metal, plastic and other materials, components of heat-resistant paints, adhesives used in various fields of engineering.
