SULPHUR CEMENT PRE-COMPOSITION AND PROCESS FOR PREPARING SUCH SULPHUR CEMENT PRE-COMPOSITION

摘要

The present invention provides a sulphur cement pre- composition, comprising sulphur and at least an organotitanate, which organotitanate is of the general molecular formula (1) or (2) : wherein OR1, OR2 and OR3 are independently chosen from acyloxy, phosphato, pyrophosphate, sulfonato and glycoxy; and XO and X'O are independently chosen from alkoxy or neoalkoxy group or XO and X'O together form a glycoxy group. The invention further provides a process for preparing such sulphur cement pre-composition, processes for the preparation of a sulphur cement product, a sulphur cement product and the use of such sulphur cement pre-composition. The invention even further relates to the use of an organotitanate stabilizing agent.
