METHOD OF PRODUCING EPOXY TRANSLUCENT ARTIFICIAL STONE IMITATING ONYX Russian patent published in 2020 - IPC C04B26/14 B44F9/04 

FIELD: construction; chemistry.

SUBSTANCE: invention relates to methods of making mortar, concrete and cement, namely, a composition of translucent artificial stone containing polyepoxides and imitating onyx. To carry out the method of making epoxy translucent artificial stone, which imitates onyx, an active diluent of epoxy resins, a mixture of amine curing agents, is added to epoxy resin. Dye and aluminium hydroxide are added to obtained mixture. Mixture is stirred and evacuated in a mixer, divided into several parts depending on the recipe of the specific texture. Dyes and additives regulating fluidity and density are added to each separate container. Mixtures are then mixed with each other in a common vessel and poured onto a matrix. Mixture is held at rest for cross-linking and polymerisation. Produced sheets are placed into the forced ventilation oven where they are heated. After cooling sheets are removed from tooling and cut.

EFFECT: technical result is the possibility of making epoxy translucent strong high-glossy sheet material - artificial stone imitating onyx without the need for further processing.
