ある。That is, it uses latex such as SBR,
Since cationic polymerization is expensive and produces undesirable products, commercially available anionic latex is used and amine groups are introduced. For example, a method for producing cationic synthetic rubber latex (US Pat. No. 3,660,324 (1))

では不十分であった。(Problems to be Solved by the Invention) The cationic latex according to each of the patent inventions described above has the following problems, since many things on the ground, such as wet surfaces, exhibit negative charges.
Latex rubber particles were electrically charged to enable effective application. However, as the uses become more diverse, it is thought that the root cause of the monoelectric charge on wet surfaces of things on earth is based on the (-) ions of silicic acid polymers that make up most of the earth's crust. Silicic acid itself is SiO4
'4-3i2076- is anionic, but rocks containing aluminosilicates, borosilicates, etc. in which a portion of silicic acid has been substituted, parasitic calcium, and other metals are extremely It is multi-column, so its anionic properties are weak, and it often shows ten charges (cationic properties). In a similar case, when blending with cement, silicate ions in aggregates such as sand are important, but cationic ions such as calcium, aluminum oxide, sodium, potassium, etc. are also important during hydration. However, in such cases, conventionally known patented inventions have not been sufficient.

植生も推奨される。(Example 2) For desert greening and to prevent the collapse of soil layers, a liquid containing the cationic latex of this invention with a solid content of about 2 to 10%,
Spraying by hand or engine, or by helicopter for large areas, is recommended. Conventionally, it has been applied only to areas rich in silica sand such as deserts and coasts, but in complex terrain, volcanic areas, etc., a mixture of the two types of cationic latex mentioned above is more effective. Vegetation mixed with plant seeds is also recommended.

It is cationically modified and sprayed on the soil layer, which contains relatively large amounts of calcium, clay, and other components, to prevent collapse. When the earth and sand layer contains a large amount of silicate ions, the cationic latexes containing no sulfonic groups according to inventions (1) to (5) described above are appropriately mixed and used. The reason why no specific manual is provided is that sediment samples vary significantly depending on where they are collected, and it is impossible to determine the recipe without experimenting.
