The present invention maintains soil below the freezing point in an unfrozen state for a long period of time, and even if it becomes frozen, the hardness of the frozen soil is low, that is, the frozen soil is soft and easy to handle. The present invention relates to a granular soil antifreeze agent. In addition to free water that can move freely due to gravity in soil and adsorbed water that forms an extremely thin film on the surface of soil particles, there is also water that forms in the voids between each particle and is absorbed by capillary force. Contains a large amount of water, such as retained water. Therefore, once the soil is cooled to below zero due to changes in the outside air, free water, adsorbed water, and retained water in the soil begin to freeze. As antifreeze agents for such freezing, there are antifreeze agents made of liquid salts, antifreeze agents made of pasty polyhydric alcohols, and the like. However, in the case of inorganic neutral salts with small molecular weights, when dissolved in water, the freezing point of the solution can be lowered, but even if this is sprinkled on soil, it will dissolve and run off due to watering or rainfall, making it ineffective. is often lost. Also,
The same can be said of polyhydric alcohols and the like. Known antifreeze agents suffer from the effects of rainfall, difficulty in uniform application, and hardness after freezing (becomes very hard).
There are many shortcomings. In addition, if neutral inorganic salts are stored before being applied to the soil, they may condense together before being applied to the soil if water is present due to humidity, etc.
Not only is it inconvenient to handle, but it often even becomes impossible to spray. The present invention solves all of these drawbacks and provides a novel soil antifreeze agent that is easy to handle, can be easily applied to soil, and has an excellent soil antifreeze effect. The present invention comprises: A: one or more neutral inorganic salts; B: a polymeric substance represented by the following formula or sodium polyacrylate; C Polycarboxylic acid, one or more types of carboxymethyl cellulose, and after dissolving and mixing the above A, B, and C in water,
The present invention relates to a soil antifreeze agent made by adding and mixing one or more higher alkyl sulfates, granulating the granules, and coating the granules with iron ammonium citrate and liquid paraffin. The soil antifreeze agent of the present invention comprises the above A, B and C.
After dissolving and mixing in water, add and mix one or more higher alkyl sulfates to form granules, add and mix iron ammonium citrate and liquid paraffin to coat the surface of the granules, and coat the surface of the granules as necessary. It can be produced by drying and dehydrating it depending on the requirements. Examples of neutral inorganic salts used in the present invention include: sodium chloride, lithium chloride,
Rock salt, table salt, calcium chloride, magnesium chloride, ammonium chloride, sodium nitrate, potassium nitrate. Neutral inorganic salts are suitable for freezing point depression. Further, as the polymeric substance represented by the following formula used in the present invention, one commercially available under the name of Isoban (manufactured by Clareisoprene Chemical Co., Ltd.) is advantageously used. This polymer material or sodium polyacrylate has good water absorption. In addition, as the polycarboxylic acid, saturated or unsaturated aliphatic, alicyclic, or aromatic polybasic carboxylic acids are used, examples of which are preferably the following: phthalic anhydride, terephthalic anhydride. acid, succinic acid,
Maleic acid, maleic anhydride, phthalic acid, itaconic acid, succinic acid, malonic acid. Polycarboxylic acid and carboxymethyl cellulose have excellent granulation effects. In the present invention, after dissolving A, B, and C in water and mixing them, one or more higher alkyl sulfates are added thereto and mixed well to form a granulated product. Higher alkyl sulfates are surfactants and have excellent emulsifying properties. Examples of higher alkyl sulfates include isooctyl sulfate, oleyl sulfate, olefin sulfate, coconut oil alcohol-based alkyl sulfate, and cetyl alcohol-based alkyl sulfate. The soil anti-freezing agent of the present invention can be obtained by adding iron ammonium citrate and liquid paraffin to the granulated product, mixing it to coat the surface, and drying and dehydrating it as necessary. The soil antifreeze agent of the present invention exhibits the excellent effect of keeping soil in an unfrozen state for a long time, and even when it reaches a frozen state, the hardness of frozen soil is low and soft frozen soil can be obtained. . Examples of the present invention are shown below, in which all parts are by weight. Example 1 Add 55 parts of NaCl, 16 parts of Na 2 SO 4 and 24 parts of MgCl 2 .6H 2 O and mix. To this mixture, 0.15 parts of Kuraray-isoban 110 (alkyl carboxylic acid copolymer), 0.05 parts of phthalic anhydride, and 0.4 parts of carboxymethyl cellulose were dissolved in 3 parts of water and mixed, and then 0.3 parts of oleyl sulfate was added to this mixture using a kneader stirrer. Department,
Add 0.03 parts of isooctyl sulfate and mix to granulate. In this granulated product, iron ammonium citrate 0.3
After adding 0.3 parts of liquid paraffin and mixing well
Dehydrate and dry in a dryer at 150℃. This yields 50 to 100 meshes of granulated antifreeze. The granular powder obtained in this way is 7 cm thick with a moisture content of
It was applied at various ratios on the surface of a 10% sand layer, and the freezing of the surface was measured, and the results shown in Table 1 were obtained. Note that rock salt was used as the conventional antifreeze agent in Table 2.
