LOW DENSITY THERMOREACTIVE MATERIAL AND METHOD FOR PRODUCTION THEREOF

摘要

FIELD: inorganic chemistry, in particular low density materials useful in form of molding article as sealing or insulating materials. ^ SUBSTANCE: claimed method includes blending of aluminum silicate hole beads with powder of epoxy or polyester resin in ratio of (2/3-1/3) pts vol. of aluminum silicate to (1/3-2/3) pts vol. of resin. Mixture is formed and heat treated at 200°C for 0.5-1.5 h. Powder of epoxy or polyester resin represents waste from powder coating or hot-drying varnishing and has particle size of 30 mum or less. Aluminum silicate hole beads have diameter of 10-100 mum. Obtained articles have bulk mass of 0.4-0.5 kg/dm3 and compression strength of 10-20 N/cm2. ^ EFFECT: thermoreactive material with low bulk mass and good compression strength. ^ 7 cl, 6 dwg
