Abstract—The conditions of synthesis of a composite material in the system consisting of an epoxy–anhydride
polymeric matrix and an analcime-containing rock were studied. Addition of the filler allows the service
characteristics to be improved by 20–25%. Samples with a low content of analcime-containing rock (up to
1 wt %) exhibit the best service characteristics.
One of promising routes of modiﬁ cation of an epoxy
polymer matrix is the use of natural layered and porous
silicates, in particular, montmorillonite and zeolites
[1–4]. The crystal structure of montmorillonite allows
the size of interlayer voids to be increased by using
various surfactants, in particular, quaternary ammonium
bases, with possible accommodation of guest molecules
in these voids . Depending on the amount of foreign
molecules, either “swelling” of intracrystalline voids or
exfoliation of a ﬁ ller particle along interlayer fragments of
the structure, with formation of a hybrid nanocomposite
, can be observed.
Zeolites (alkali and alkaline-earth metal alumino-
silicates) are porous bodies characterized by a deﬁ nite
framework structure and regular pore geometry
(intracrystalline voids and channels) into which various
molecules can penetrate upon dehydration. Exchangeable
cations and aluminosilicate framework can be modiﬁ ed by
chemical treatment, which allows control over chemical
forces acting on sorbed molecules .
In this connection, it is of certain interest to combine
two types of ﬁ llers, e.g., mineral rocks, containing both
montmorillonite and zeolite. In addition, the development
of mineral-ﬁ lled polymeric composite materials with
new service properties and functional possibilities is an
important factor for efﬁ cient utilization of natural raw
materials and for development of new resource-saving
In this study we examined the physicochemical features
of the synthesis of a polymeric composite material in the
system consisting of an epoxy polymer matrix and of
a zeolite- and montmorillonite-containing rock.
As a polymeric matrix we used a well-known system of
ED-20 epoxy–4,4’-isopropylidenediphenol oligomer and
isomethyltetrahydrophthalic anhydride (iso-MTHPA).
The mineral composition of the analcime- and
montmorillonite-containing rock is given in Table 1.
Chemical transformations occurring in the course
of heat treatment of an analcime-containing rock
were studied with an МОМ Q-1500D derivatograph
at a heating rate of 5 deg min
The phase composition was refined by X-ray
phase analysis. The diffraction patterns were taken
with a DRON-4M diffractometer using CuK
(λ = 1.5418 Å).
