い。The concentration of the ammonium salt in the snow melting agent composition of the present invention is 10 to 300 with respect to 100 parts by weight of urea.
Parts by weight, preferably 20 to 200 parts by weight. When the amount of ammonium salt is 10 parts or less with respect to 100 parts by weight of urea, the snow melting effect is reduced, and further, adverse effects such as an increase in corrosiveness with respect to metals occur. Even if the amount is 300 parts by weight or more, the snow melting effect is not improved, and the effect of reducing the corrosiveness against metals is eliminated, which is not economically advantageous.

全に使用することができる。As shown in the examples, the snow-melting agent composition of the present invention has a lower freezing temperature and higher anti-freezing effect than urea used as a snow-melting agent. In addition to the freezing temperature, the snow melting effect is related to physical properties such as snow temperature (ice temperature), deliquescent, and heat of melting, and is difficult to quantitatively evaluate because it is affected by the weather conditions during use. Since the ammonium salt used in the snow melting agent composition of the present invention has a large deliquescent property, the snow melting effect in the actual snow melting experiment in Niigata has the same effect as calcium chloride. Further, the snow melting agent composition of the present invention has almost no corrosiveness to metals and can be used extremely safely in any place.
