ENVIRONMENTALLY FRIENDLY EPOXYAMINE FILLED COMPOSITIONS OF LOW-TEMPERATURE CURING.

It is established that in comparison with other polymeric binders, the processes of obtaining the epoxy-amine compositions, used in construction, meet 8 of 12 principles of "green" chemistry. It is shown that the use of low-molecular weight substances as acid catalysts of the curing reaction reduces the value of E-factor by one order and the value of atom efficiency of the process by two orders. It is experimentally proved that the disperse mineral fillers, which have hydroxyl groups with various functions of acidity on the surface, can be used for the acceleration of reaction of cross-linking in the production of polymeric construction materials based on the epoxyamine compositions. This will allow to improve the environmental safety of the preparation, application, use and utilization of these materials by the exclusion of toxic and environmentally hazardous to humans and biosphere low-molecular weight substances.
