との重量比が4:1〜1:1である融氷雪剤である。(Means for Solving the Problems) In view of the above problems, the present inventors have excellent slip resistance without impairing the excellent melt-and-snow performance of the water-soluble inorganic salt having deliquescent property, and are inexpensive melt-and-snow snow. The agent was thoroughly studied.
As a result, in addition to the water-soluble deliquescent water-soluble inorganic salt in combination with a specific ratio of ammonium chloride, the problems caused by the concentration of the snow-melting snow-melting agent are solved, and the intended purpose is achieved. The inventors have found the present invention and have proposed the present invention. That is, the present invention is a deliquescent water-soluble inorganic salt (hereinafter, also simply referred to as "water-soluble inorganic salt") and ammonium chloride as a main component, the weight ratio of the water-soluble inorganic salt and ammonium chloride is 4: It is a 1 to 1: 1 ice melting snow agent.

目的はより効果的に達成されると考えられる。The present invention is characterized in that it is used as a composition consisting of ammonium chloride and a water-soluble inorganic salt having deliquescent property, and the ice-melting agent for such a composition has a viscosity of only the water-soluble inorganic salt during melting snow. It is lower than that of, and the slip resistance of the road surface increases, so it does not easily slip, and ammonium chloride also has snow-melting snow performance. Therefore, the excellent ice-melting snow performance of the deliquescent water-soluble inorganic salt is not impaired. Rather, the main purpose of the ice-melting snow agent is to penetrate into the fixed portion between the snow and snow and the road surface, and in view of improving the peelability of the portion, the ice-melting snow agent of the present invention exhibits a rapid effect on the ice-melting snow. After the water-soluble inorganic salt reaches the road surface, the slow-acting ammonium chloride gradually exerts the snow-melting property on the road surface, and therefore the above object is considered to be achieved more effectively.
