Abstract

The changes in the thermophysical and fire- and heat-shielding properties of compounds based on ethylene propylene rubber when hollow aluminosilicate microspheres (MSPs) are introduced were studied. The MSPs were treated with a heteroorganic modifier – phosphorus–boron–nitrogen-containing oligomer (PEDA), which is a combustion inhibitor. The physicomechanical characteristics of the vulcanisates and the magnitude of the Payne effect were determined. The vulcanisates contained 30 parts filler BS 120 and a sulphur vulcanising group, and also 1 part MSPs. The optimum MSP/PEDA ratio was 1:3. The ultra-high-frequency treatment of the mixture of MSPs and PEDA was especially effective. Using a Versa 3D electron microscope, the increase in the diameter of MSPs as a result of modification and the change in the atomic composition of the surface of MSPs were recorded. The modification of MSPs leads to a reduction in the Payne effect, to an increase in the interaction between rubber and filler, to a reduction in density, and to an increase in the cohesive strength. By comparison with a specimen without MSPs, the rate of linear combustion according to GOST 28157-89 decreases by 10%. The modification of MSPs leads to a decrease in this parameter by 5% by comparison with a specimen containing unmodified MSPs. The time of heating to 100°C of the unheated surface of a specimen heated on the other side to 2000°C increases by 50–60% and 11–19% respectively. The resistance to separation under conditions of erosion entrainment increases by 4–7%. The use of PEDA makes it possible to improve the adhesion of coating to substrate. A scheme of the interaction of MSPs and PEDA is put forward.
用异质有机改性剂*改性微球的热屏蔽弹性材料
研究了引入中空硅酸铝微球(MSPs)后,乙丙橡胶基化合物的热物理性能和防火隔热性能的变化。用杂有机改性剂含磷硼氮低聚物(PEDA)处理MSPs, PEDA是一种燃烧抑制剂。测定了硫化胶的物理力学特性和佩恩效应的大小。硫化胶含有30份填料bs120和硫硫化基团,还有1份msp。最佳MSP/PEDA比为1:3。MSPs与PEDA混合的超高频治疗效果特别好。利用Versa三维电子显微镜,记录了改性后MSPs直径的增加以及MSPs表面原子组成的变化。MSPs的改性导致Payne效应减弱,橡胶与填料之间的相互作用增加,密度降低,内聚强度增加。与不含MSPs的试样相比,根据GOST 28157-89的线性燃烧速率降低了10%。与未修改MSPs的样品相比,MSPs的修改导致该参数降低5%。另一侧加热至2000℃的试样,其未加热面加热至100℃的时间分别增加了50-60%和11-19%。在冲蚀夹带条件下,其抗分离能力提高了4-7%。PEDA的使用可以提高涂层与基材的附着力。提出了一种MSPs与PEDA相互作用的方案。
