FIELD: chemistry.

SUBSTANCE: invention relates to the field of polymeric binders based on epoxy oligomer with a filler in the form of short fibers to polymeric composite materials (PCM) obtained from the sheet semifinished (SMC-prepreg) the method of direct pressing (sheet moulding compound - SMC-technology) which they can be used to manufacture interior and infrastructure. Epoxyvinylether Binder includes, mass. %: unsaturated oligomer epoxy type 23.0÷37.0, hardener solution 2.0÷6.5, inhibitor solution 0.005÷0.100, thermoplastic solution 0.2÷5.5, a mixture of surface active substances 0.200÷2.995, aluminium hydroxide 23.043.5, magnesium oxide 1.0÷3.5, polyisocyanate3.0÷0.5, an inorganic mineral filler 15.0÷30.0. In addition, the binder may contain zinc stearate in an amount of 0.5-2.5%. SMC-prepreg includes masses. %: 70.0-85.0 epoxy binder, chopped fiberfill 15.0-30.0.

EFFECT: invention allows the creation of cost-effective products from PCM with low shrinkage and increased moisture resistance during prolonged use in open spaces in the environment.
