高级硼酸酯型制动液
摘要：
本发明公开了一种高级硼酸酯型制动液，按质量百分比计，包括下列组分：多乙二醇甲醚：5～8％，三羟基聚氧化丙烯醚：0.5～1.0％，三乙二醇甲醚硼酸酯：80～88％，苯丙三氮唑：0.2～0.4％，N-苯基吗啉：0.3～0.5％，2，2-二(4-羟基苯基)丙烷：0.5～0.9％，硫代二丙酸双十二醇酯：0.04～0.10％，4，4′-亚丁基双(6-特丁基间甲酚)：0.1～0.2％，2，2′-(环己基亚氨基)二乙醇：0.05～0.10％，十二烯基丁二酸(T746)：0.1～0.2％，碱度调节剂：0.5～13.05％。其优点是：不仅具有满足国家标准GB12981-2003要求的高低温性能，还具有良好的低温运动粘度和耐腐蚀效果，其特殊耐久金属腐蚀性能从GB12981-2003规定的120h延长到了480h，极大提高了高级硼酸酯型制动液的适应性能，可以满足长期耐久使用的要求。
摘要（英）：

The invention disclose an advanced borate type braking fluid which comprises the following components in mass percent: 5-8% of methoxypolyethylene glycol, 0.5-1.0% of trihydroxy-polyoxypropylene ether, 80-88% of triethylene glycol methyl ether borate, 0.2-0.4% of benzotriazol, 0.3-0.5% of N-phenylmorpholine, 0.5-0.9% of 2,2-bis(4-hydroxyphenyl)propane, 0.04-0.10% of thiodipropionic acid didodecyl alcohol ester, 0.1-0.2% of 4,4'-butylidene-bis(6-tert-m-cresol), 0.05-0.10% of 2,2'-(cyclohexylimino)bis-ethanol, 0.1-0.2% of dodecencylsuccinic acid (T746) and 0.5-13.05% of alkalinity regulator. The advanced borate type braking fluid not only has high and low temperature properties meeting GB12981-2003 requirements, but also has good low-temperature kinematic viscosity and corrosion resistant effect, and the special durable metal corrosion resistant time is prolonged to 480h from 120h specified in GB12981-2003, thereby greatly improving the adaptability of the advanced borate type braking fluid, and meeting the requirement on long-term durable use.
