Description

Manufacturing method and method of waterproofing soil modifying material

The present invention relates to a method of producing a waterproofing material and a method of using the same to prevent water from being infiltrated into land or preventing water from evaporating in the ground.

Conventionally, weeds were weed by hand or grassing machines or by pesticide spraying at places where we would like to suppress the occurrence of weeds, for example, in a median separator of roads, playgrounds, golf courses, or the like. Pulling work was hard work, which required a lot of labor as needed and was dangerous in the median of roads. There was also a danger of harming the environment when spraying pesticides.

The problem to be solved by the present invention is to prevent rainwater from being dumped semi-permanently to land without adversely affecting the environment, to prevent the water from rising in the ground, or from leaking water containing harmful substances from harmful wastes It is in the cage. The waterproofed soil modifying material of the present invention is one in which one or a plurality of raw material particles selected from a group of silicon, earth, sand, small stones, and household waste are burned with silicon.

A feature of the present invention for producing the waterproofing soil modifying material is that it comprises a soil selected from the group consisting of soil, sand, small stones, and household ash waste containing silicon dried to a moisture content of about 0 to 5% Or a plurality of raw materials are mixed with an emulsion of water and silicone oil, wetted in an emulsion, and then heated and dried at 180 to 200 ° C to coat the raw material particles with silicon.

Since the soil modifying material manufactured by the above method is laid on the ground, rainwater does not penetrate into the soil, so that it can be used for preventing germination of the soil covered with the soil modifying material. In addition, uninfluenced rainwater can be used to dry unpacked soil because it evaporates quickly due to solar heat or wind. When this soil modifying material is laid on the ground, the descent of the rainwater is prevented by the soil modifying material, so that the soil on the soil modifying material can not be dried, so it can be used for preventing the drying.

[Example]

The method for producing the waterproofing soil modifying material of the present invention is as follows.

The raw material is one or more selected from soil, sand, small stones, incineration of household waste, etc., soil including sand, that is, soil, sandstone, marine, small stone with small particle diameter, incineration ash of household waste discharged from incinerator, One or more of these may be the raw material. For example, the ash can be added to the soil. In view of easiness to obtain, relatively low price and easiness to handle, Masato (a kind of soil) is used as a raw material in the embodiment. First, remove the raw material, Masato, from the sieve, and set the diameter of the entrance to 0 ~ 10mm. The single particle diameter does not need to be particularly careful, and is set at a maximum of about 10 mm for the convenience of subsequent processing and product handling. Then, the mixture is stirred with a mixer for about 2 to 3 minutes while being heated to 180 to 200 ° C by a mixer, and the moisture content is dried to about 0 to 5%, followed by drying and tumbling. The heating temperature and the heating time can be appropriately selected depending on the nature and amount of the raw material, and as a result, the moisture content may be about 0 to 5%. On the other hand, about 3 cc of a commercially available silicone oil is mixed with 1000 cc of water and stirred with a mixer to make an emulsion. The mixing ratio of the silicone oil is appropriately increased or decreased depending on the properties of the raw material and the particle diameter. For example, when the raw material is substantially sand, the amount of silicone oil can be reduced. In addition, this commercially available silicone oil is a colorless, odorless transparent synthetic oil, and is not particularly regarded as a manufacturer. 20 liters of the emulsion is mixed with the dried soil (1 t) at a room temperature using a mixer for about 10 minutes, and then dried at about 180 to 200 ° C in a drier to evaporate water. By this, silicon is coated on the surface of the particles of Masato. The waterproofed soil modifier thus obtained is excellent in water resistance and does not decompose unless heated to 260 DEG C or higher because it is resistant to heat, so that the waterproof property is not permanently lost. Also, since it is non-toxic odor, it does not degrade even when it enters small animals or plants, so it does not adversely affect the ecosystem. It is also excellent in air permeability, does not become solid even at a low temperature of -50 ° C, and does not lose its waterproofness. Also, when heated to about 260 ℃ or more, the hydrogen attached to the silicon and oxygen remains as water, and comes back to the original soil.

Examples of the use of the soil modifying material having excellent waterproofing properties will be described below.

[Use Example 1]

The waterproof surface layer is formed by spreading a waterproofing material with a thickness of about 5 ~ 10cm on the ground to prevent the weeding of the road separator, playground, drying of unpacked ground, prevention of sludge and prevention of frost pillar . Because of the excellent waterproofness of the waterproof surface layer, rainwater does not penetrate the soil under the waterproof surface layer, and the waterproof surface layer is dried down, thereby preventing the germination of weeds and the like. Rainwater that does not penetrate also evaporates rapidly by solar heat or wind.

[Use Example 2]

For the cultivation of plants in dry places, a waterproofing basement layer is formed by spreading soil modifying material about 5 ~ 10 cm under the roots of plants. The waterproof basement prevents rainwater from falling, so the soil on the soil is not dried and the plant is easy to grow.

[Example 3]

In a place where agricultural chemicals are sprayed on the lawn of a golf course, a waterproof basement layer is formed by spreading an soil modifying material on a tubular or plate-like slanting slope in the soil. The waterproofing basement layer leads to the drainage means such as a tank without pouring pesticides and other harmful substances into the ground. The water collected in the drain means is recovered and processed.

[Example 4]

Waste soil containing harmful substances such as industrial waste is wrapped well with soil modifying material to form a waterproof packaging layer. The waterproof packaging layer prevents water containing harmful substances from being sent to the outside.

It has semi-permanent waterproof property, is innocuous and harmless, can be widely used for preventing weeds, drying of the ground or drying of land, and sealing of harmful substances without adversely affecting the environment. Its manufacturing method is simple and does not require a special apparatus, and is inexpensive because it uses low-cost raw materials.
