COMPOSITION FOR PRODUCING CATION-EXCHANGE FIBRE MATERIAL Russian patent published in 2014 - IPC C08L61/10 C08L61/04 C08K7/04 C08J5/20 C02F1/42 

FIELD: chemistry.

SUBSTANCE: composition is also used to soften and desalinate process water, in production of synthetic detergents, in the paint industry and industry of polymer materials. The composition for producing cation-exchange fibre material consists of paraphenol sulphonic acid, formalin, basalt wool subjected to preliminary heat treatment for 1 hour at 350-450°C and microwave treatment at radiation power of 750 W for 30 s, and further contains phenol resin - a phenol production waste. The composition contains, wt %: paraphenol sulphonic acid 48.4-54.4, formalin 35.3, heat- and microwave-treated basalt wool 9.1, phenol resin 1.2-7.2.

EFFECT: composition enables synthesis of cation-exchange fibre material with an improved set of properties, particularly higher static exchange capacity and low filtrate oxidation susceptibility, and solves the problem of recycling phenol resin.
