应用加工助剂提高冷喂料挤出质量

Application of processing aids to improve cold-feed extrudate quality

研究了增塑剂A和胶易素T 78在轮胎胎面胶中的应用。结果表明 ,在原生产配方中加入 1 5份增塑剂A和 0 8份胶易素T 78,可明显地降低胶料的门尼粘度 ,改善胶料的流动性及加工工艺性能 ,解决了冷喂料挤出过程中出现的因混炼胶分散不均而造成挤出胎面有气孔和气泡等质量问题。

The application of plasticizer A and Gum easy T 78 to tire tread compound was investigated.The results showed that the Mooney viscosity of the compound decreased significantly,the flowability and processibity of the compound improved,and the blisters in the cold feed extruded tread resulted from the unevenly dispersed mix were eliminated by adding 1 5 phr of plastisizer A and 0 8 phr of Gum easy T 78.
