ら植物成育面に好影響を及ぼすことが示唆されている。A method of melting snow by spraying carbon black or a mixture thereof with a powder such as siliceous earth on agricultural land, ranches, golf courses, etc. has been known for a long time. Snow melting by carbon black progresses based on the effect of black heat absorption,
f Carbon Black in Non-Ru
According to bberIndustries, “P. 3,
Channel black at a rate of 500g/rrf topsoil 5
It is said that by spraying it in a thickness of 1 cm, it will raise the soil temperature by 1 to 2°C. In addition, it has been suggested that carbon black has a positive effect on plant growth, although it is unclear, such as having the effect of suppressing drying in the soil.
これらカーボンブラック系融雪剤の散布は対象地域が小

なわれる。Spraying of these carbon black-based snow melting agents is carried out by hand when the target area is small, or by aerial spraying from a helicopter or light aircraft when the target area is large.
ところが、カーボンブラックは極めて軽量の微粉体であ

に伴うカーボンブラック消費量ならびに作業量の増大化
、あるいは堆積残留したカーボンブラックの乾燥飛散に
よる環境汚染等を惹起する。However, since carbon black is an extremely lightweight fine powder, it is difficult to spread it uniformly over the target area, and in many cases, the amount of spraying is localized. For this reason,
Areas that have not been sprayed must be sprayed again, and in areas where too much is sprayed, the carbon blank will remain in the soil even after the snow melts, resulting in a reduction in carbon black consumption due to respraying. This also causes an increase in the amount of work or environmental pollution due to drying and scattering of the carbon black that remains deposited.
［発明が解決しようとする課題］
上記のような従来事情から、カーボンブラックを最小有
効量で均一散布することができれば融雪効果ばかりでな
く、経済面、公害防止面からの効能も多大となる。[Problems to be Solved by the Invention] Based on the above-mentioned conventional circumstances, if carbon black can be uniformly dispersed in the minimum effective amount, it will not only have a snow melting effect but also have great economic and pollution prevention effects.
通常、この種の粉状体を均一に散布するための手段とし
て水に分散してから散水または噴霧する方法が考えられ
る。しかし、カーボンブラックは著しく疎水性界面を有
する微小粒子であるため、水への分散性は極めて悪い。Usually, as a means for uniformly dispersing this type of powder, a method of dispersing it in water and then sprinkling or spraying it is considered. However, since carbon black is a fine particle having an extremely hydrophobic interface, its dispersibility in water is extremely poor.
本発明は、カーボンブラックにフミン酸を併用すること
による水分散性の向上ならびに土壌改良機能を活用した
水性懸濁液からなる融雪剤を提供するものである。The present invention provides a snow melting agent consisting of an aqueous suspension that utilizes improved water dispersibility and soil improvement function by using humic acid in combination with carbon black.

をもつカーボンブラックを用いることが望ましい。There are no particular restrictions on the type, properties, etc. of carbon black that can be used in the present invention, but it has a slow burying speed in snow when snow melts, and humic acid, which is a soil improvement component, is effectively adsorbed and supported within particle aggregates. It is desirable to use carbon black which has a large agglomerated structure with an acrylate Stokes diameter of 100 nm or more.

子表面性状を改質して親水性に転化し、水に対する分散
性を著しく向上させる働きをする。Humic acid is an alkali-soluble, amorphous polymeric organic acid found in young crusts such as peat and lignite with a low degree of coalification, and is known to have soil improvement functions similar to humic acid (compost component). There is. Moreover, humic acid modifies the surface properties of carbon black particles to make them hydrophilic, thereby significantly improving their dispersibility in water.
フミン酸は、水溶性のアンモニウム塩、カリウム塩もし
くはカルシウム塩として供用することが好適である。Humic acid is preferably used as a water-soluble ammonium salt, potassium salt, or calcium salt.

することが望ましい。An effective way to treat carbon black with an aqueous humate solution is to knead it into a paste using an appropriate device such as a kneader-1 granulator. Sufficient effects are exhibited at 10% by weight or less. Carbon black treated with dispersibility modification in this way is stirred and mixed with water to form an aqueous suspension, but the concentration as a spray liquid is preferably at most 20% by weight from the viewpoint of workability such as spraying. It is desirable to set the content to 15% by weight or less.

なり、融雪の進行速度も早くなる。The carbon black dispersed on the snow surface gradually penetrates and buries into the snow together with the suspended water, but in this process, solar energy is absorbed not only on the snow surface as when dispersing powder, but also on the snow volume unit. do. This action makes the snow melting effect more uniform and speeds up the progress of snow melting.

進行を一層促進するために機能する。Carbon black after melting snow is absorbed as water permeates into the soil, stays at an appropriate depth in the soil, and releases the humic acid supported in the atarigate into the soil. At the same time, carbon black continues to absorb solar heat energy by coloring the soil, and functions to further promote plant growth due to humic acid soil improvement.
