Method for preparing ternary complex antiager and emulsion and application thereof in neoprene

三元复合防老剂、乳液的制造方法及在氯丁橡胶中的应用

Abstract

三元复合防老剂、乳液的制造方法及在氯丁橡胶中的应用,由一种双酚单丙烯酸酯类防老剂、一种受阻酚类防老剂和一种硫醚防老剂按着规定的配比进行复配,混合,制成三元复合防老剂;室温下,将上述方法制备的三元复合防老剂用有机溶剂溶解,然后加入歧化松香酸皂水溶液与磺酸类阴离子表面活性剂水溶液的混合物制成的乳化剂进行充分的混合,分散后制成三元复合型防老剂乳液;在合成氯丁橡胶胶乳中,按着氯丁橡胶的干胶质量计为1∶0.03~0.07的比例添加三元复合防老剂乳液。老化实验研究表明:添加了本发明的三元复合防老剂乳液制成的氯丁橡胶产品,其橡胶外观颜色、门尼黏度、门尼焦烧时间、力学强度性能指标均优于使用防老剂BHT所制成的氯丁橡胶产品。
The invention provides a method for preparing ternary complex antiager and an emulsion and an application thereof in neoprene. The ternary complex antiager is prepared by formulation and mixing of a bisphenol mono-acrylate antiager, a hindered phenolic antiager and a sulfoether antiager according to specified proportioning. The preparation method comprises the following steps: dissolving the ternary complex antiager prepared by the above method with an organic solvent at room temperature; adding an emulsifying agent prepared by the mixture of disproportionated rosin acid soap water solution and sulfoacid anionicsurfactant water solution for fully mixing; and obtaining the ternary complex antiager emulsion after dispersing. In the process of synthesizing the neoprene rubber latex, the ratioof the dry glue of the neoprene in terms of the added ternary complex antiager emulsion is 1:0.03-0.07. The research of an aging test shows that the neoprene product prepared by adding the ternary complex antiager emulsion of the invention is superior to the neoprene product prepared by using the antiager BHT in the aspects of appearance color, Mooney viscosity, Mooney scorch time and mechanicalintensity property indexes.
