凍結防止・融雪材および凍結防止・融雪方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-freezing / snow melting material and an anti-freezing / snow melting method for preventing freezing of a road surface, a farm, a ground, etc., and melting snow.

あることも知られている。2. Description of the Related Art A method of spraying chemical substances such as calcium chloride and magnesium chloride has been adopted as a method of preventing freezing or snow melting on road surfaces such as highways.
It is also known that charcoal powder has a property of absorbing and retaining solar heat to heat surrounding objects, and is effective in preventing freezing of road surfaces and farmland and snow melting.

壌に含まれていると、動植物の育成に悪影響を与える。The above-mentioned method of spraying chemical substances such as calcium chloride has a problem that the sprayed chemical substances remain on the road surface or the ground or are mixed with water to cause salt damage. . Specifically, corrosion of the vehicle traveling on the road surface or deterioration of the material may be caused. In agricultural land, if soil contains chemical substances such as calcium chloride, it will adversely affect the growth of plants and animals.

で、余計に粉塵として飛散し易くなる。The above-mentioned charcoal is excellent in that it has no problem of salt damage, but it has a problem that dust of charcoal is scattered to stain the road surface and surrounding buildings black. Since the specific gravity of charcoal is light, the charcoal sprayed may scatter on surfaces other than the specified road surface or soil surface, and the desired function may not be fully exerted. Since charcoal has poor pressure resistance and is finely broken by the load of a vehicle or the like, it is more likely to be scattered as dust.

しておく。The antifreezing / snow melting material of the present invention comprises pitch coke grains having a grain size of 0.5 to 10 mm, a carbon content of 97% or more, and a hardness of 5.1 kg or more. Pitch coke particles are coke particles produced from pitch obtained by distilling coal tar or petroleum, that is, pitch coke powder particles. The carbon rate and hardness can be set according to the manufacturing conditions of the pitch coke grains. The pitch coke particles produced in this manner may contain fine particles with a particle size of less than 0.5 mm, so fine particles with a particle size of less than 0.5 mm can be cut and washed (aeration). Remove it.

It has the same function as the above-mentioned charcoal powder with respect to the function of preventing freezing or snow melting, such as absorbing and holding solar heat to heat surrounding objects. Pitch coke grains made of carbon have no fear of causing salt damage such as calcium chloride, and do not pollute the environment even if they are absorbed by the road surface or soil or scattered in the air.

材としても機能する。Since the pitch coke grains have higher hardness than charcoal as well as ordinary sand, they are not destroyed or generate fine dust even when a load such as a vehicle is applied. Since no fine dust is generated, it does not pollute the road surface or surrounding buildings like charcoal. Since it has a large specific gravity, it is difficult to scatter. In addition, since the specific gravity is large, it will be naturally buried in the soil due to its own weight after it has been sprayed, and since it is promoted to be buried in the soil due to rainfall, it will eventually become a carbon component of the soil. It also functions as a soil improver.

ができる。In particular, the pitch coke grains are in the form of polyhedral grains having an acute angle, and therefore have a high anti-slip function of preventing a vehicle, a pedestrian or the like from slipping on the road surface. Moreover, since the hardness is high as described above, it is difficult for the corners of the polyhedron grain to be chipped or worn even when a load such as a vehicle is applied, and a good slip prevention function can be exerted for a long period of time.

In addition, since it has the effect of adsorbing ionic substances such as salt, when used in combination with chemical substances such as calcium chloride as an anti-freezing / snow melting material, it prevents the scattering of calcium chloride and reduces salt damage. can do.
