POLYMER-MINERAL SOLUTION FOR IMPREGNATING FRAME MADE OF MINERAL AGGREGATE Russian patent published in 2014 - IPC C04B26/06 C04B111/20 

FIELD: chemistry.

SUBSTANCE: polymer-mineral solution for impregnating a frame made of a mineral aggregate, which includes polyether acrylate resin, a hardening initiator, a hardening accelerator and an additive, the hardening initiator being cyclohexanone peroxide, the hardening accelerator being cobalt octoate and the additive being a mixture of quartz filling materials having two particle sizes of 0.071-0.16 mm and 0.16-0.315 mm in ratio of 3:1, said impregnation being carried out by filling voids in the hardened frame with said solution, said frame being obtained by moulding a mixture of the following composition, wt %: polyether acrylate resin 6.0, cyclohexanone peroxide 0.12, cobalt octoate 0.28, granite chips with size of 5-8 mm 93.6, with the following ratio of components, wt %: polyether acrylate resin 24-28, cyclohexanone peroxide 0.48-0.56, cobalt octoate 1.1-1.29, mixture of quartz filling materials having two particle sizes 0.071-0.16 and 0.16-0.315 in ratio of 3:1 - the balance.

EFFECT: improved strength properties.
