  The antifreeze of the present invention is including propylene glycol, first material, and second material. The first material is normal aliphatic dicarboxylic acid in which number of carbon atoms is from 10 to 12, salt of the normal aliphatic dicarboxylic acid, or mixture thereof. The second material is benzimidazole compound which has a benzimidazole skeleton, salt of the benzimidazole compound, triazine compound which has a triazine skeleton and has a mercapto group, salt of the triazine compound, or mixture thereof. Such antifreeze has less environment load than antifreeze including ethylene glycol. Furthermore, such antifreeze does not cause metal to corrode more than the antifreeze including ethylene glycol.

  本发明的防冻剂包括丙二醇、第一种材料和第二种材料。第一种材料是碳原子数为 10 至 12 的普通脂肪族二羧酸、普通脂肪族二羧酸的盐或它们的混合物。第二种材料是具有苯并咪唑骨架的苯并咪唑化合物、苯并咪唑化合物的盐、具有三嗪骨架并带有巯基的三嗪化合物、三嗪化合物的盐或它们的混合物。与包括乙二醇在内的防冻剂相比，这种防冻剂对环境的负荷较小。此外，与含乙二醇的防冻剂相比，这种防冻剂不会对金属造成更大的腐蚀。
