Abstract

New polymer composite materials (PCMs) were obtained based on a mixture of phenol–formaldehyde and phthalide-containing phenol–formaldehyde resole-type binders reinforced with polyoxadiazole fiber, and their tribological properties were investigated. A study was made of the effect of the content of the phthalide-containing phenol–formaldehyde polymer in the two-component mixture of binders on the hardness of the surface layer and the tribological and thermofrictional properties of the PCM in various systems of dry friction on steel. It was shown that the resulting PCMs are superior in tribological and thermofrictional properties to PCMs based on phenol–formaldehyde or phthalide-containing phenol–formaldehyde resole-type binders.

基于双组分改性苯酚-甲醛粘合剂的减摩复合材料

摘要基于聚噁二唑纤维增强的苯酚-甲醛和含邻苯二甲酸苯酚-甲醛树脂型粘合剂混合物，获得了新型聚合物复合材料（PCM），并对其摩擦学特性进行了研究。研究了双组分混合物粘合剂中含苯酞酚醛聚合物的含量对表层硬度以及 PCM 在各种钢材干摩擦体系中的摩擦学和热摩擦性能的影响。结果表明，与基于苯酚-甲醛或含邻苯二甲酸苯酚-甲醛树脂型粘合剂的 PCM 相比，所产生的 PCM 在摩擦学和热摩擦特性方面更胜一筹。
