中文摘要:
      胶乳蛋白分为结合蛋白和水溶性蛋白,而天然橡胶过敏原主要来自水溶性蛋白。吸附沉淀法和 酶解法针对不同类型的蛋白质产生作用。以不同脱蛋白方式得到的脱蛋白橡胶为研究对象,研究不同的蛋 白去除方式对天然橡胶的外观特性、门尼粘度、硫化特性、力学性能等影响。结果表明,酶解法水解脱蛋白 工艺能有效降低总蛋白质含量,而吸附沉淀法脱蛋白工艺能有效去除水溶性蛋白质,同时兼顾其他非胶物 质的纯化,达到降低蛋白水平降低过敏性与纯化橡胶的双重目的。在性能保持方面,吸附沉淀法优于酶法 脱蛋白。
英文摘要:
      Latex proteins are divided into binding proteins and water-soluble proteins,while the water-soluble proteins are recognized allergen of natural rubber. The adsorption precipitation method and enzyme hydrolysis method are used to handle the latex and act on different types of proteins. The deproteinized natural rubbers by different preparation had been studied,on and investigated the effect on appearance of natural rubber,Mooney viscosity, curing characteristics,mechanical properties and so on. The results showed that the properties including mooney viscosity,mechanical properties and heat aging properties could be reduced by the degree of protein removal increases. Enzymatic hydrolysis of protein removal process could effectively reduce the total protein content,while the adsorption precipitation process could effectively remove water-soluble proteins and other non-rubber substances and achieve the double purpose of reducing allergy and purifying rubber. Adsorption precipitation method for protein removal is superior to enzyme hydrolysis method .
