硼酸酯型汽车制动液的研制和开发

Preparation and Development of Boric Acid Ester Type Brake Liquor for Cars

以硼酸酯为主体,含有润滑剂、稀释剂和添加剂的HZ_3、HZ_4型汽车制动液,具有优良的高温抗气阻性、良好的低温流动性。对金属无腐蚀,对橡胶不溶胀,能保证汽车行驶安全。

Take boric acid ester as major component,mixing with lubricants, diluents, and additives, the so prepared HZ3 and HZ(?) type brake liquors for cars possess excellent high temperature anti - gasblock property, good low temperature fluidity, non - corrosive to metals, no swelling effect to rubber, and thus ensures the safety for running cars.
