Description

Sea urchin avoidance paint and manufacturing method thereof {PAINT AVOIDED BY SEA URCHIN AND PREPARING METHOD FOR THE SAME}

The present invention relates to a sea urchin avoiding paint containing tannic acid or derivatives thereof and a method for producing the same.

The value of aquatic biological resources is high value not only as a food resource but also in medicine, medicine and health food. Algae among aquatic organisms contain various high value-added useful materials and are being studied in various fields, and their importance and necessity are increasing.

Unlike land plants, seaweeds are exposed to heavy metals, salinity and temperature because they are exposed to 100% water in the habitat. Among them, seaweeds are most affected by water temperature, and the yield per unit area is much higher than that of land plants. .

At present, due to the effects of global warming, many seaweeds disappear from the coast of Korea. The algae recording is a phenomenon in which algae that have not adapted to the rapid increase in water temperature due to global warming are killed, and calcite-free lime algae are formed first on the basal surface before new algae can grow.

Governments around the world, including the Korean government, are artificially creating seaweed forests through artificial reef projects. Artificial reef structures made of materials such as cement, ceramics, and steel are used to create an environment for new algae to grow and increase the rate of joining algae using fertilizers to create a seaweed forest.

Even though seaweeds grow in the algae forest creation project, they are ingested by sea urchins, especially sea urchins, including purple sea urchins, so that the seaweeds cannot survive, and lime algae grow on the empty basal surface. Blocking is urgent.

In order to prevent the damage caused by breakfast animals, the government is carrying out relief work, mainly protecting the seaweed by causing skin scuba to kick sea urchins directly. In 2011, Gyeongsangnam-do, Korea spent a lot of money on sea urchin relief, including KRW 200 million. However, existing sea urchin relief work is expensive, and if there is a natural disaster such as strong winds, typhoons, it is difficult to make relief work. Except for the existing methods of sea urchin rescue work, studies to block sea urchins are inadequate in the world.

Since no material is used at all, the marine environment and the human body are not harmed at all. However, since it is not a natural substance, long-term follow-up observation is required or the effect of avoiding breakfast animals such as sea urchins is insufficient. Therefore, development demands in related industries for sea urchin avoidance paints are increasing.
