将天然胶乳膜浸泡在不同pH值的氢氧化钾溶液中。研究了浸渍对膜的交联度、可提取蛋白含量和拉伸性能的影响。氢氧化钾溶液通过从天然胶乳膜中浸出可提取蛋白，从而有效地降低了可提取蛋白的含量。结果表明，随着KOH溶液pH的升高，膜的交联度和可提取蛋白含量降低。除断裂伸长率外，其它拉伸性能在pH高于12时均有所下降，尤其是当pH大于12.0时，可提取蛋白含量降低更明显。
Natural rubber latex films were soaked in potassium hydroxide solution of various pH. The effects of soaking on the crosslink density, extractable protein content and tensile properties of the films were investigated. Potassium hydroxide solution was believed to be effective in reducing extractable protein content by leaching out the extractable protein from natural rubber latex films. Results showed that crosslink density and the extractable protein content of the films reduced with increasing pH of the KOH solution. The tensile properties, except elongation at break, reduce when pH of KOH solution is above 12. Extractable protein content was reduced especially when the pH of the solution was greater than 12.0.
