文章研究了有机硅聚氨酯低聚物对丁腈橡胶СКН-26M等硫化胶硫化网络结构形成的影响。由于在高温作用下,有机硅聚氨酯低聚体能够积极地参与丁腈橡胶等合成橡胶的热硫化过程,从而对橡胶硫化网络的形成产生积极的影响。具体表现为能提高橡胶硫化网络的密度和力学性能,并且在高温下能较长时间的保持橡胶的弹性和强度性能。这就为制造在高温下使用的具有较长使用寿命的橡胶工业制品创造了条件。
In this paper, the effects of silicone urethane oligomers on the formation of sulfide vulcanizates such as acrylonitrile-butadiene rubber СКН-26M were studied. Silicone urethane oligomers can actively participate in the thermal vulcanization of synthetic rubbers such as nitrile butadiene rubber (NR) due to the high temperature effect, which has a positive impact on the formation of rubber vulcanizates. Specific performance can improve the density and mechanical properties of rubber vulcanization network, and at a high temperature for a long time to maintain the flexibility and strength of the rubber properties. This creates the conditions for the manufacture of rubber industrial products that have a long service life at high temperatures.
