Research of the Influence of Carbon Microfiber on the Properties of Elastomer Fire-Protective Materials

The influence of carbon microfiber on the physicomechanical, thermophysical, and fireproof characteristics of elastomeric compositions based on ethylene propylene diene rubber is considered. Microfibrous filler contributes to the manifestation of the effect of “micro-reinforcement,” which leads to an increase in the heatprotective properties of the material due to the increase in the strength of coke. The correction of microfibers with a phosphorus-boron-containing oligomer enhances the carbonization of the material, which leads to an increase in the warming-up time of the unheated sample surface by 8–10% and a decrease in the linear combustion rate by 10–15% compared to known analogues.     

Chlorosulfonated polyethylene modified with aminoderivatives of glycidyl methacrylate

The products of interactions between glycidyl ester of methacrylic acid and aniline were used as modifiers for chlorosulfonated polyethylene adhesives providing an enhanced strength of adhesive joints between vulcanized rubbers.     

Adhesive compounds based on natural rubber,modified by nitrogen-containing compounds

The possibility of modifying adhesive compounds based on natural rubber by nitrogen-containing adhesion promoters has been studied. It was shown that the properties of modified adhesive compounds based on natural rubber are comparable to those of adhesive compounds based on polychloroprene, as well as that the implementation of the elaborated technology will enable one to obtain high-strength constructions based on different rubbers.     

Improvement of adhesion strength of compositions based on chlorosulfonated polyethylene to rubbers

In order to increase the adhesion strength to rubbers, chlorosulfonated polyethylene was modified with amino-containing compounds. It is shown that such modification increases the adhesion strength of the compositions to resins by two to five times.     

Development of adhesive ozone-resistant compositions based on chlorosulfonated polyethylene for elastomeric materials

Chlorosulfonated polyethylene (CSPE) is modified by a Diafen FP amine-containing compound. It is shown that compositions based on modified CSPE can be used as adhesive compositions for rubber splicing and coatings for rubber protection from ozone aging.     

Modification of adhesive compositions based on polychloroprene with element-containing adhesion promoters

The possibility of using nitrogen-containing compounds as highly efficient adhesion promoters for adhesive compositions based on polychloroprene is studied. Common regularities of enhancing the adhesion strength of a glue bond for vulcanizates based on variable rubbers are revealed.     

Adhesive compositions based on perchlorovinyl resin with enhanced adhesion to polymeric elastic materials

A possibility of modifying the adhesive compositions based on perchlorovinyl resin with amino-containing compounds is studied. Aniline and N-nitrosodiphenylamine were used as amino-containing adhesion promoters. It is shown that, at an optimal content of an adhesion promoter, ED-20 resin, and plasticizer additives in the gluing composition, the bond strength of vulcanized resins based on different rubbers and linoleum increases by 1.7–3.3 times.     

Development of phosphorus-boron-nitrogen-containing modifier for elastomeric compositions

Synthesis of phosphorus-boron-nitrogen-containing modifier (PEDA) has been performed, and the properties thereof have been studied. It has been shown that introduction of PEDA as a modifying additive in elastomeric compositions makes it possible to improve their adhesive and fire–heat protective properties.     

Study of mechanisms for the improvement of adhesive properties of polychloroprene-based compositions by their modification with amine-containing compounds

Possible mechanisms for an increase in the adhesion parameters of polychloroprene-based adhesive compositions modified with adhesion promoters on the basis of epoxy compounds and aniline derivatives are studied.
