FIELD: chemistry.
SUBSTANCE: invention relates to thermal-protective materials. A fibre-forming solution is prepared from aluminium oxychloride, silica sol and an organic polymer. The mixture of initial components is used in form of a dry concentrate which is dissolved in water of required viscosity. The dry concentrate of the mixture of initial components is dissolved in water heated to 40-60°C in air while constantly stirring at a rate of 200-400 rpm.
EFFECT: shorter process cycle, increased controllability of the process of achieving the required viscosity of fibre-forming solution and stability of the chemical composition and properties of the obtained fibre.
