Abstract

At present, the footwear industry of the Republic of Belarus faces the task of developing optimal approaches to the replacement of expensive and high-quality imported materials with domestic equivalents. The latter should also look preferable to imported ones from the economic point of view. Therefore, it is obvious that these equivalents should reproduce the main characteristics of world-class footwear materials or approach them, but at the same time have a low cost.

The use of recycled raw materials for obtaining new materials with high added value is one of the options for the development of composite materials industry. The introduction of various kinds of cheap fillers in the form of by-products of wood processing in the composition of secondary polyurethane foam allows for significant cost reduction and improvement of properties.

The aim of the research is to develop the technology for obtaining materials for the external parts of shoe bottoms, including the necessary list of operations for its implementation, as well as the recipe composition for injection moulding. Research methods: standard methods of assessment of physical-mechanical, elastic-strength and operational properties for materials (shoe plates).

Results: It has been determined that values of properties of materials (shoe plates) are higher when manufacturing modified and filled granulate as an intermediate product. Further moulding of products (casting of materials and soles) allows for obtaining the specified (required) property values.
