METHOD FOR PRODUCING ANTIFREEZE AGENT
To provide a method for producing an antifreeze agent by using a chloride and a corrosion inhibitor, where these materials can be mixed homogeneously.SOLUTION: Provided is a method for producing an antifreeze agent, comprising: charging as materials of the antifreeze agent a chloride, an antifreeze component, and a hydrate of disodium hydrogen phosphate, a corrosion inhibiting component, into a blender; performing blending while maintaining the temperature of the blender in a range of 50°C-95°C so that the disodium hydrogen phosphate reaches a temperature at which at least a part of its crystal water dissolves; and, after completion of blending, cooling the mixture in the blender to room temperature to obtain an antifreeze agent. The temperature of the blender is in a range of 70°C-80°C. When the total material of the antifreeze agent is set to 100 mass%, the chloride amounts to 97-99 mass% and the hydrate of disodium hydrogen phosphate amounts to 3-1 mass%.SELECTED DRAWING: Figure 1
【課題】塩化物と防錆剤とを用いた凍結防止剤の製造方法において、これらの材料を均一に混合させることができる凍結防止剤の製造方法を提供する。【解決手段】凍結防止剤の材料として、凍結防止成分である塩化物と、防錆成分であるリン酸水素二ナトリウムの水和物とを混合機に投入し、前記リン酸水素二ナトリウムがその結晶水の少なくとも一部が溶解する温度となるように前記混合機の温度を５０℃〜９５℃の範囲に維持して混合を行い、混合完了後、前記混合機内の混合物を室温に冷却して凍結防止剤として取得することを特徴とする凍結防止剤の製造方法である。前記混合機の温度が７０℃〜８０℃の範囲である。前記凍結防止剤の材料全体を１００質量％としたとき、前記塩化物が９７〜９９質量％、前記リン酸水素二ナトリウムの水和物が３〜１質量％である。【選択図】図１
