Problems solved by technology

[0003] At present, there are many types of artificial fish reefs, such as concrete artificial fish reefs, which are relatively strong and can be made into different shapes according to requirements. They are one of the most widely used artificial fish reefs. The ordinary Portland cement used has a high pH value, which is not conducive to the attachment and growth of algae, and its carbon emissions are high; salt erosion and biological corrosion in the ocean lead to expansion and deterioration of concrete and corrosion of steel bars, which shortens the life of reinforced concrete artificial fish reefs. Reduced, and it needs to consume a lot of cement, sand, stone and other materials, so the cost is high; another example is the steel artificial reef, after the parts are prepared in the factory, they are transported to the dock, and then assembled and put on site, the cost is high It is not easy to popularize and popularize; another example is bamboo or wooden reefs, which have poor wind and wave resistance and are easily corroded, so this kind of reefs are rarely used; another example is waste artificial reefs, which mainly use waste tires, waste tires, waste It is formed by stacking ship hulls, which has the characteristics of low cost, but the waste contains many harmful substances, which is easy to cause environmental pollution

Abstract

The invention belongs to the technical field of artificial fish reefs, and particularly relates to artificial fish reef materials and a method for preparing a fish reef thereof. Raw materials of polyethylene, cellulose-thiosemicarbazide, bentonite, illite powder, coupling agent KH-550 and tert-butylsilane vinyl triperoxide are adopted to be prepared into an artificial fish reef. The fish reef hasthe advantages of low mass, low cost, high strength, corrosion resisting, environmental friendliness and long service life, heavy metal ions and other harmful substances can be effectively absorbed, and the growing environment of fish, shellfish and shrimp can be ensured.

Description

technical field [0001] The invention belongs to the technical field of artificial fish reefs, in particular to an artificial fish reef material and a method for preparing the fish reefs. Background technique [0002] Artificial fish reefs are structures that people set up scientifically in oceans and freshwater rivers to improve the ecological environment of the watershed and provide necessary, A safe habitat to achieve the purpose of protecting and multiplying fishery resources and increasing catches; there are many microorganisms attached to the surface of the artificial reef, and a large number of algae grow there. It can be used as a hidden place for fish to escape from harmful organisms. It can provide abundant bait and a good growth and breeding environment. At the same time, it can change the flow direction and velocity of oceans and rivers, causing them to generate rising eddies and back vortices, so as to diffuse nutrients and promote the abundance of nutrients at t...
