摘要目前PVC糊制品在工业、生活中应用十分广泛,但其中添加的大量增塑剂,容易受温度、压力以及相接触的介质影响,挥发到空气中、被液体抽出或者渗入到固体中,影响制品的性能和使用,并且危害人体健康。本文主要通过不同增塑糊的性能研究,选择出具有优质性能并且符合绿色健康的环保型增塑糊。主要采用先进的科学方法测试增塑糊的粘度、凝胶化性能、增塑剂迁移程度等方面的性能,对比不同种类增塑剂以及配比对增塑糊质量性能方面的影响。探索出环保型增塑剂,促进我国工业科技在这方面的发展。58529
Abstract The PVC paste products are widely used in industrial or life,but added a large amount of plasticizer,easily influenced by temperature,pressure and the medium influence contact,evaporate into the air,infiltrate been withdrawn liquid or solid,influence on the performance and use of products,and endanger human body health. This paper mainly through the performance study of different plasticized paste,choosing the excellent performance and conforms to the green,healthy and environmentally friendly plasticized paste. This article adopts the advanced scientific method test of plasticized paste viscosity,gelation properties,and degree of plasticizer migration performance,comparing different types of plasticizer and the influence of the ratio of plasticized paste quality performance. Explore environmental protection plasticizer to promote the development of industrial technology in our country..
