A study of the modifying effect of additions of boric acid polymethylene-p-triphenyl ester in rubber-based polymer composites.

摘要

In an earlier work, [1, 2] the prospects of using phenol polymethylene ether and boric acid polymethylene-p-triphenyl ester as modifiers for friction polymer composites containing rubbers and operating in high-duty friction assemblies in a wide temperature range were shown. For the case of standard brake linings it was demonstrated that, with the addition of 5 wt% boron-containing polymer, there is a considerable increase in strength and heat and wear resistance [2]. This increase in strength, in our view, occurs by the interaction of the organoboron modifier with sulphur to form a three-dimensional vulcanisation network, while the presence of a boron atom in the composition of the polymer suggests an increase in interaction between all components of the composite. This work is devoted to a study of the properties of composites that may, in our view, confirm the formation of three-dimensional interpenetrating polymer networks when the friction composites are modified with a boron-containing polymer.
