FIELD: chemistry.
SUBSTANCE: invention relates to production of technical paper with a polymer coating, in particular to methods of applying coatings capable of hardening on paper substrates, and a method of producing paper with a heat-resistant polymer coating. Method involves formation on a paper substrate of an adhesive, coloured ground and lacquer layers from compositions based on a thermosetting aqueous acrylic dispersion. Each of the layers is cured successively during application onto the substrate. First, partially at temperature of 60–70 °C for 3–5 minutes, and then finally at 150–160 °C for 5–7 minutes simultaneously with surface finishing of relief embossing of material by pressing under pressure of 25–30 kgf/cm2.
EFFECT: invention provides high heat resistance of the material and the possibility of its subsequent use in technological processes associated with high-temperature action, and environmental friendliness of the technology of its manufacture.
