Problems solved by technology

[0008] The main technical problem to be solved by the present invention is that the surface of the reef body and the nearby seawater are alkaline due to the continuous dissolution of calcium hydroxide in the seawater of ordinary concrete artificial fish, which has a harmful effect on the breeding of ordinary marine organisms, and the existing concrete Poor waterproof performance, easy to be eroded by salt in seawater defects, providing a preparation method for artificial fish reefs

Abstract

The invention discloses a preparation method of an artificial fish reef, and belongs to the technical field of marine environment protection. The method comprises the steps that sodium bentonite withthe water isolation effect is added into concrete base slurry, concrete is foamed to form concrete of a porous structure, exterior some metal ions can be fixed after the concrete is molded, sodium silicate is dissolved into water, a gel sodium silicate water solution is formed, and therefore the waterproof permeability of the concrete is improved. A protecting agent of a waterproof duct is modified phenolic resin, molybdenite mountain flour and liquid paraffin are added, molybdenite contains a large number of sulfur elements, the artificial fish reef adopts polymine as an amine modifying agent, due to the silicon oxide amine functionalization on the surface of concrete, silicon dioxide and phenolic aldehyde resin can be subjected to dehydration condensation, the artificial fish reef adoptsporous concrete of the dense micro structure as the base material, the waterproof protective agent covers the surface and internal macro duct, more alga biologies can grow fixedly, surrounding fish can be attracted, and the application project is wide.

Description

technical field [0001] The invention discloses a preparation method of an artificial fish reef, which belongs to the technical field of marine environment protection. Background technique [0002] Artificial reefs are artificially set up seabed accumulations that induce fish to gather and inhabit. Artificial reefs generally have a more obvious fish-collecting effect, which can prolong the time for fish to stay in the reef area, expand the fishing ground, and enable fish to proliferate. It has been found that flounder, flounder, sea bream, and grouper, black bream, six line fish and other sedentary rock fish have better fish collection and multiplication effects. Floating fish reefs have a good effect on attracting tuna, skipjack, bamboo fish, etc. The utilization rate and catch of fishing operations in artificial reef areas are generally higher than those in the surrounding sea areas, and some catches can be doubled. The effect of shallow proliferating reefs is also signi...
