IMPACT OF DIFFERENT DISPERSED MICROFIBER FILLERS ON ADHESION AND FIRE AND HEAT PROTECTIVE PROPERTIES OF ELASTOMERIC COMPOSITIONS
The paper is related to the research on impact of fiber fillers (polyamide, carbon, basalt and asbestos fiber fillers) on adhesion and cohesion properties of gluing compositions based on polychloroprene. It has been determined that modification of gluing compositions with fiber fillers having functionally active groups in their structure provides an effect of multilayer modifying in a glue joint that increases adhesion characteristics of the last one due to the action of different adhesion mechanisms. A possibility of applying the developed gluing compositions as fire and heat protective coatings has been investigated as well. The investigation has showed improved fire resistance of rubber substrates with the layered coatings containing the microfibers to open flame. It has been established that the modification significantly enhances adhesion and fire protective properties of gluing compositions that, in turn, can expand their application areas.
