しても有害であり、環境汚染の一因ともなっていた。Conventional anti-icing agents or snow-melting agents that are sprayed on roads, etc. have been made by dissolving sodium chloride, calcium chloride, magnesium chloride, etc. in water or using them in powder form. However, because these compounds contain a lot of salt, they are highly corrosive to metals, and when sprayed on roads, they corrode the metal parts of structures such as automobiles, aircraft, and sewers, causing rust and destruction. Not only was it harmful to crops and seafood, but it was also a contributing factor to environmental pollution.
本発明はかかる事情に鑑みてなされ、腐蝕性や毒性の少

It is characterized by being a ~35% aqueous solution.

上述の化合物を良好に分散させる分散媒として作用する
ものである。The glycol used is a viscous glycol such as ethylene glycol or propylene glycol, which has a high viscosity and is difficult to freeze, so even when dissolved in water, the freezing point of the aqueous solution is lowered and acts as an antifreeze. Further, urea has endothermic properties, and when dissolved in water, it has the property of absorbing heat from the solvent. For this reason, the aqueous solution containing urea releases heat into the environment, raising the environmental temperature and melting snow.
It has an ice-melting effect. Sodium formate is a salt consisting of a strong acid and a strong base, and completely ionizes in an aqueous solution, significantly lowering the freezing point of the aqueous solution. In addition, this sodium formate is easily separated and does not remain for a long period of time unlike sodium chloride, so it causes less harm to the environment. As the alcohol, liquid alcohol such as methanol, ethanol or propatool is selected,
It acts as a dispersion medium that disperses the above-mentioned compounds well.

コール5〜25部であり、使用目的、使用状況に応じて
この範囲内で適宜増減が可能である。下記i1表はかか
る配合比の一例を示している。The blending ratio of these compounds is 35 to 55 parts of glycol,
The amounts are 1 to 10 parts of urea, 25 to 45 parts of sodium formate, and 5 to 25 parts of alcohol, and can be adjusted as appropriate within these ranges depending on the purpose and conditions of use. Table i1 below shows an example of such a blending ratio.
(以下余白)
第 1 表
以上のように調合された混合物は、次いで水に溶解され
、25〜35%の水溶液の状態で道路面等に散布される
。この濃度も混合物の配合比と同様に調整されるもので
あり、融氷、融雪速度゛を上昇させる場合には高濃度の
水溶液が使用される。(The following is a blank space) Table 1 The mixture prepared as shown above is then dissolved in water and sprayed on roads etc. in the form of a 25-35% aqueous solution. This concentration is also adjusted in the same way as the blending ratio of the mixture, and a highly concentrated aqueous solution is used to increase the ice and snow melting rate.
実施例1
第1表の配合比で得られた混合物を水に溶解して濃度3
0%の融雪剤を調合した、この融雪剤を1n1″当り、
0,5jの割合で道路上の雪に散布し、時間経過を観察
した。この場合、外気温は+1゜θ℃〜−10,8℃で
あり、湿度は、40〜92%であった。
1散布後、0.5時間経

0.5〜1時間で道路の舗装面が表れ、2時間後には、
はとんどの雪が融けた。Example 1 A mixture obtained at the blending ratio shown in Table 1 was dissolved in water to give a concentration of 3.
This snow melting agent mixed with 0% snow melting agent per 1n1″,
It was sprinkled on the snow on the road at a rate of 0.5j and the time course was observed. In this case, the outside temperature was +1° θ°C to -10.8°C, and the humidity was 40 to 92%.
After 0.5 hours after the first application, the snow becomes sherbet-like, containing a large amount of water.
The paved surface of the road appears in 0.5 to 1 hour, and after 2 hours,
Most of the snow has melted.
実施例2
実施例1と全く同等に調合した水溶液を、氷1ゴに対し
て0.57散布して時間経過を観察した。Example 2 An aqueous solution prepared in exactly the same manner as in Example 1 was sprinkled at a rate of 0.57 per ice cube, and the elapsed time was observed.
2時間後に氷の2anまで浸透し、5時間後には4m、
10時間後に8cm、15時間後に12〜16(至)に
まで浸透して道路の舗装面まで到達した。その後、除氷
作業を行ったが、この作業は従来の碌〜純の所要時間で
終了した。After 2 hours, it penetrated to 2 an of ice, and after 5 hours, it penetrated to 4 m,
It penetrated to a depth of 8 cm after 10 hours, and to a depth of 12 to 16 cm after 15 hours, reaching the paved surface of the road. Afterwards, de-icing work was carried out, but this work was completed in the usual time required.
以上のような本発明によると、金属に対する腐蝕性が少
ないため自動車や舗装道路等の構造物に対する弊害が小
さい。又、植物や魚介類に対する毒性も少なく、環境を
汚染することがない。さらに融雪、融氷速度が大きく、
早期に融雪、融氷が行われる、という効果がある。According to the present invention as described above, since there is little corrosiveness to metals, there is little harm to structures such as automobiles and paved roads. Furthermore, it is less toxic to plants and seafood, and does not pollute the environment. Furthermore, the speed of snow and ice melting is high,
This has the effect of melting snow and ice early.
