Abstract

The invention relates to a shark repellant and a preparation method thereof, belonging to the technical field of chemical engineering. The shark repellant is prepared by adopting the steps: sulfonating oil-soluble nigrosin and fuming sulphuric acid to generate a sulfonation product; performing a dilution and neutralization process on the sulfonation product, deep phreatic water, calcium carbonate and triisobutyl carbonate, then mixing a production obtained through suction filtration, concentration and drying with cupric acetate according to a certain ratio and grinding to obtain the shark repellant. The shark repellant is powder, can be rapidly dissolved an dispersed into seawater, and releases a black-blue solution with a flavor of a copper acetate chemical, a shark can rapidly leave when in decomposed solution, thus a protection function of repelling the shark for life saving is achieved. The shark repellant is widely applicable for underwater operations, marine fishing, deep sea training and the like due to a large range of a protection region.

Description

technical field [0001] The invention relates to a shark repellent and a preparation method thereof, belonging to the technical field of chemical product production. Background technique [0002] Sharks are considered by some to be one of the most aggressive fish in the ocean. There are about 380 species of sharks in the world, 30 species will actively attack people, 7 species may cause human injury, and 27 species are dangerous because of their size and habits. According to fossil investigations and scientists' calculations, it is known that sharks have lived on the earth for about 400 million years. It has existed as early as 400 million years ago, and its appearance has not changed much, which shows that its survival ability is extremely strong. It is called "ocean hunter" ". [0003] The most ferocious in the ocean is the great white shark. Their powerful jaws can shred almost any prey they catch. They live at the top of the marine food chain. The reason why it attacks...
