15.1 INTRODUCTION
In recent time the mineral fillers attract attention as active filling agents in polymer
composites [1, 2]. Thanks to these fillers many properties of the composites are im-
proved increases the durability and rigidity, decrease the shrinkage during harden-
ing process and water absorption, improves thermal stability, fire proof and dielectric
properties, and finally the price of composites becomes cheaper [3-5]. At the same
time it must be noted that the mineral fillers at high content lead to some impair of
different physical properties of composites. Therefore, the attentions of the scientists
are attracted to substances, which would be remove mentioned leaks. It is known that
silicon organic substances (both low and high molecular) reveal hydrophobic proper-
ties, high elasticity and durability in wide range of filling and temperatures [6, 7].
The purpose of presented work is the investigation effect of modify by tetraethyl
orthosilicate (TEOS) of the mineral diatomite as main ¿ ller and same mineral with an-
desite (binary ¿ ller) on some physical properties of composites based on epoxy resin.
15.2 BASIC PART
The mineral diatomite as a filler was used. The organic solvents were purified by dry-
ing and distillation. The purity of starting compounds was controlled by an LKhM-8-
MD gas liquid chromatography, phase SKTF-100 (10%, the NAW chromosorb, carrier
gas He, 2m column). Fourier transform infrared (FTIR) spectra were recorded on a
Jasco FTIR-4200 device.
