摘要
硫酸钙晶须是一种性价比高、绿色环保材料,其结构完整,力学性能优异,是塑料、橡胶、胶粘剂等材料改性时的重要增强组元。本文介绍了硫酸钙晶须的主要性能和制备方法,并对其在塑料中的应用进行了综述。当硫酸钙晶须填充量为5%～20%时,塑料的耐热性、拉伸强度、耐摩擦性、弹性模量等性能有明显提高。
As an environment friendly material,calcium sulfate whisker is one of the important intensifiers for material modification with high cost performance in plastic,rubber,adhesive,due to its structural integrity and excellent mechanical properties.The main properties of calcium sulfate whisker are introduced and its preparation and application in plastics are reviewed.When the amount of whisker was 5% ～ 20%,the performance of plastics,including thermostability,tensile strength,abrasion resistance,elastic modulus,was improved obviously.
