FIELD: textile, paper.
SUBSTANCE: invention relates to papermaking technology, precisely to production of modified paper with higher gas-proof and heat-protective properties, and can be applied in constructions, aircraft and automobile constructions, shipbuilding. The method includes treatment of paper with the mixture of 5-7% aqueous solution of polyvinyl alcohol with 5-7% aqueous solution of chitosan at their ratio 1:1 within 10-15 minutes, thereafter treatment with 15-20% aqueous solution of methyl phosphate borate and drying.
EFFECT: prepared modified paper has increased gas-proof and heat-protective properties, and resistance to thermal-oxidative degradation.
