A method for producing sulphuric binding agent, a sulphuric binding agent, sulphur concrete and a method for producing sulphur concrete and application of liquid product of polystyrene pyrolysis

摘要

Object of the invention is a method of preparation of sulphuric binding agent based on sulphur and olefin hydrocarbons is characterised in that sulphur at the amount from 70 wt% to 96 wt% is heated under an inert gas atmosphere, and is fed with the olefin hydrocarbons at the amount from 4 wt% to 30 wt%, and then the reaction mixture is gradually heated to a temperature not higher than 150°C and maintained at such temperature for 3 to 4 hours under constant mixing, the olefin hydrocarbons including a liquid product derived from polystyrene pyrolysis PPS, which is added at a weight ratio of at least 1:1 referred to the remaining olefin hydrocarbons. Object of the invention is also the sulphuric binding agent and the sulphur concrete as well as the methods of its preparation.
