COMPOSITION FOR PRODUCING FIRE-RESISTANT CONSTRUCTION MATERIAL IN RECYCLING WASTES Russian patent published in 2020 - IPC C04B26/08 C04B111/28 

FIELD: construction.

SUBSTANCE: invention relates to production of construction and finishing materials, which can be used both for external and internal finishing of premises as skin of houses, facade cladding articles, terrace board, tiles, finishing materials and other articles and structures, including in humid environments. Composition for producing fire-resistant construction material based on wastes and modifying additives includes, pts. wt.: industrial PVC polyvinyl chloride wastes with Ficenter pulse constant (58–64) ± 1 100, expanded vermiculite wastes 20–37, Naftomix MRX 2167 heat-stable stabilizer 4–5.5, processability modifier Paraloid K 175 0.7–1, impact resistance modifier Paraloid KM1 4.5–5.2, modulus of impact strength Tyrin 6000 1.7–2, Listab Ca lubricant 0.15–0.2, pigments 2–5.

EFFECT: technical result is low water absorption, high strength and impact strength of fire-resistant construction material obtained from the disclosed composition, recycling industrial waste.
