增黏树脂是橡胶加工过程中重要的助剂之一,其主要作用是提升橡胶胶料的自黏性和互黏性,改善轮胎加工成型和使用性能,减少胎胚质量缺陷。目前被轮胎、橡胶行业广泛应用的增黏树脂,主要包括烷基酚乙炔树脂、烷基酚甲醛树脂、古马隆树脂以及石油树脂等,其中综合性能最好的是烷基酚乙炔树脂。烷基酚乙炔树脂具有高增黏性、长效性、耐湿热性、低压缩生热等优异性能,具有其他增黏树脂无法比拟的性能。其增黏机理为:树脂中不仅含有
Tackifying resin is one of the most important additives in rubber processing. Its main function is to improve the self-adhesive and mutual viscosity of rubber compounds, to improve the processing and forming properties of tires and to reduce the defects of the quality of the embryo. At present, the tackifying resins widely used in tire and rubber industry mainly include alkylphenol acetylene resin, alkylphenol formaldehyde resin, coumarone resin and petroleum resin, among which the best overall performance is alkylphenol acetylene resin. Alkylphenol acetylene resin with high viscosity, long-lasting, heat-resistant, low compression heat and other excellent performance, with other tackifying resin unmatched performance. The thickening mechanism is: the resin contains not only
