FIELD: construction materials.
SUBSTANCE: method for producing shaped and linear polystyrene articles with a 3D texture of wood of various species or stone, resistant to weather conditions and UV radiation. The method includes co-extrusion in two extruders. Moreover, when extruding the inner layer of polystyrene in the main extruder, a foaming agent is added, and when extruding the outer reinforced layer of impact-resistant polystyrene in the auxiliary extruder, coloring pigments and UV stabilizers are added, followed by cooling, hardening and drying with compressed air of the entire product, thermal transfer and embossing of the pre-applied pattern wood of various species or stone from a transport film to the outer hardened layer of the product.
EFFECT: creation of a shaped and linear articles that are resistant to the effects of natural conditions, mechanical damage, rotting, and corrosion.
