发明名称 METHOD OF PREPARING POROUS MATERIALS
摘要 FIELD: chemical industry. SUBSTANCE: porous materials are prepared by mixing binder and porous mineral natural filler with moisture content of not more than 15% selected from group consisting of zeolite, shungite, apatite, perlite, dialomite, trepel and mixtures thereof during molding process on heating. Binder is binder based on thermoreactive resin, e.g. unsaturated oligoethermaleinate or oligoetheracrylate resin, mixtures thereof and epoxyoligomers in combination with hardening initiators in amount of 5-25 wt % per 100 wt % of binder. Foaming is carried out at 60-160 C for time required for complete hardening of resin. EFFECT: greater strength and higher chemical and heat resistance of the porous material and reduced shrinkage deformations. 11 ex, 1 tbl
