汽车制动液  汽车液压制动系统中传递制动压力的液态介质。对汽车制动液的性能要求是:粘温性好,凝固点低,低温流动性好;沸点高,高温下不产生气阻;使用过程中品质变化小,并不引起金属件和橡胶件的腐蚀和变质。    制动液有三种类型。①蓖麻油-醇型:用精制蓖麻油和乙醇按1:1配制而成。在寒冷地区,用蓖麻油34%、丙三醇(甘油)13%、乙醇53%配制成的制动液,在-35℃左右仍能保证正常制动,但沸点低,易产生气阻。②合成型:用醚、醇、酯等掺入润滑、抗氧化、防锈、抗橡胶溶胀等添加剂制成,使用性能良好,工作温度可高达150℃,但价格较高。③矿油型:用精制的轻柴油馏分加入稠化剂和其他添加剂制成,工作温度范围为-70℃至150℃。它的使用性能良好,但制动系统须配用耐矿油的橡胶件。中国的矿油型制动液分"7号"和"9号"两种,"7号"用于严寒地区,"9号"用于气温不低于-25℃的地区。各种制动液不可混存和混用,否则会出现分层而失去作用。
