CONSTRUCTION AND FINISHING MATERIAL Russian patent published in 2024 - IPC C04B28/02 

FIELD: construction.

SUBSTANCE: invention relates to construction materials and specifically to production of mixtures and compositions for arranging protective and decorative coatings for both external and internal finishing of buildings and structures. Solution of the technical task is achieved due to the fact that the construction and finishing material contains a mineral binder, that is cement, a mineral filler, that is sand, polymer component in form of a mixture of epoxy resin, amine type curing agent and copolymer of styrene, acrylic acid and butyl acrylate, modifying additive activated by thermal treatment at temperature up to 200°C tripoli, a functional additive and water with the following content of components, wt.%: mineral binder - cement 18–21, mineral filler - sand 33.5–42, tripoli 0.5–3, functional additive 0–2, epoxy resin 1–3, amine type curing agent 0.5–1.5, copolymer of styrene, acrylic acid and butyl acrylate 17–21, water - 6.5–15.

EFFECT: creation of polymer-cement construction and finishing material with improved complex of physical and mechanical properties.
