Abstract

Изобретение относится к антифризу, используемому в автомобилях для перевозки СПГ, и к способу его изготовления Оно предлагает новый антифриз для использования в автомобилях для перевозки СПГ в холодных регионах, имеющий превосходные антикоррозийные и антинакипинные свойства при высокой температуре кипения и низкой температуре замерзания. Антифриз, используемый в автомобилях для перевозки СПГ, состоит из следующих веществ, мас.%: 35-55% этиленгликоля, 5-30% диметилсульфоксида, 0,1-0,3% молибдата натрия, 0,1-0,4% дигидрофосфата калия, 0,1-0,6% бензотриазола, 0,1-0,3% о-фталевой кислоты, 0,1-0,3% м-фталевой кислоты, 0,05-0,8% меркаптобензотиазола, 0,1-0,3% нитрата натрия, 0,05-0,2% бензоата натрия, 0,1-0,5% гидрата натрия, 0,0005-0,0015% флуоресцеина, остальное до 100 мас.% композиции составляет деионизированная вода.The invention relates to antifreeze used in vehicles for transporting LNG, and to a method for its manufacture. It provides a new antifreeze for use in vehicles for transporting LNG in cold regions, having excellent anti-corrosion and anti-scale properties at a high boiling point and low freezing point. The antifreeze used in vehicles for LNG transportation consists of the following substances, wt.%: 35-55% ethylene glycol, 5-30% dimethyl sulfoxide, 0.1-0.3% sodium molybdate, 0.1-0.4% dihydrogen phosphate potassium, 0.1-0.6% benzotriazole, 0.1-0.3% o-phthalic acid, 0.1-0.3% m-phthalic acid, 0.05-0.8% mercaptobenzothiazole, 0, 1-0.3% sodium nitrate, 0.05-0.2% sodium benzoate, 0.1-0.5% sodium hydrate, 0.0005-0.0015% fluorescein, the rest up to 100 wt.% Of the composition is deionized water.
