Sulfron D3515是一种芳纶浆粕型的混料添加剂,既可用于炭黑混料也可用于白炭黑和炭黑混料,可以降低滞后效应。在SulfronD3515高温混料过程中产生的反应中间体会与炭黑颗粒起化学反应,降低填料-填料之间的相互作用(改进了Payne效应),因而降低了混料的摩擦能量,使混料的滞后性能得以改善。其化学反应过程原理是基于自由基化学,它与填料和高分子的化学反应同时进行。另外,芳纶的加入也可以增强橡胶基体的强度。一、实验部分
Sulfron D3515 is a Kevlar pulp type compounding additive that can be used in both carbon black and carbon black blends to reduce hysteresis. The reaction intermediates produced during the high temperature compounding of Sulfron D3515 react chemically with the carbon black particles to reduce the filler-filler interaction (improving the Payne effect), thereby reducing the frictional energy of the compound and allowing the hysteresis of the compound Performance is improved. The chemical reaction process principle is based on free radical chemistry, which is carried out simultaneously with the chemical reactions of fillers and polymers. In addition, the addition of aramid fiber can also enhance the strength of the rubber matrix. First, the experimental part
