Оцінка можливості використання вторинної мінеральної сировини виробництва соняшникової олії у складах еластомерних композицій

We determined the characteristics of products obtained from secondary raw materials from the sunflower oil production as highly dispersed thermostable mineral fillers of elastomeric compositions. It is shown that they contain triacylglycerides and esters of monocarbonic acids with monoatomic long-chain alcohols as an organic fraction. We assessed the influence of 10, 20 and 30 wt. part of sludge after filtration and its purified form on technological and physicalmechanical properties of elastomeric compositions based on nonstereoregular butadiene-methylstyrene rubber of the brand SKMS30 ARK relative to the action if kaolin. It is shown that the purified form of the sludge after the filtration of sunflower oil is a mineral filler of the semi-reinforcing action which provides improved technological properties to the rubber compounds, as well as enhanced kinetic parameters of sulfuric vulcanization. This filler can be recommended for use in rubber compounds for the compression method of manufacturing rubber products.
