СПОСОБЫ УЛУЧШЕНИЯ СВОЙСТВ ПОЛИМЕРНЫХ КОМПОЗИТОВ НА ОСНОВЕ МОДИФИЦИРОВАННОГО ДИАТОМИТА

Abstract

This publication discusses possible ways to increase the physical, mechanical and operational properties of paint and varnish coatings by introducing a mineral filler, including a modified filler.  In the production of paints and varnishes, mineral fillers are used as inexpensive components to reduce production costs. By selecting fillers, it is possible to significantly improve such characteristics of paints and varnishes as adhesion, moisture resistance, viscosity, pouring, weather resistance, mechanical strength, hardness, etc. The main trends in the development of formulations of paints and varnishes using new types of fillers are outlined. Various methods of treating the surface of fillers and their influence on the properties of paints and coatings are considered.  American scientists have presented a paint and varnish composition that includes from 20 to 97% (by weight) of filler. The filler includes at least one material with a hollow structure. Such a filler can be diatomite, zeolite or carbon. According to geological prospecting data, siliceous rocks within the Aktobe region of the Republic of Kazakhstan are widespread. Most of the surface of the areas is occupied by siliceous Paleogene deposits, forming numerous deposits of diatomites.
