A canvas-based artificial fish reef and its preparation method

Abstract

The invention discloses a canvas-based artificial fish reef and a preparation method thereof, which is characterized in that: the artificial fish reef includes a canvas body, the outer surface of the canvas body is coated with a first protective layer, and the first protective layer The outer surface of the layer is coated with a second protective layer; the first protective layer is prepared from the following components in parts by weight: 7-10 parts of redispersible latex powder, 15-25 parts of polyurethane, 100-200 parts of cement 70-150 parts of water; the raw materials of each part by weight of the second protective layer include: 440-470 parts of cement, 30-80 parts of fly ash, 20-50 parts of mineral powder, and 910-960 parts of crushed stone , 680-730 parts of sand, 8-15 parts of soda ash, 2-5 parts of quicklime, 10-40 parts of redispersible latex powder, and 220-260 parts of water; the canvas-based artificial fish reef is a tent-like structure. It has the advantages of suitable weight, easy salvage and repair, and can effectively improve the rooting stability of seaweed, and the overall fish reef is not easy to crack and has strong toughness.

Description

technical field [0001] The invention relates to the technical field of artificial fish reefs, in particular to a canvas-based artificial fish reef and a preparation method thereof. Background technique [0002] Artificial reefs refer to artificial facilities that are composed of one or more natural or artificial objects and are purposefully placed in seawater to improve the ecological environment, increase fishery resources, and promote social and economic development. The artificial reef construction project is one of the marine fishery ecological projects emerging in the 20th century, and is an important part of the marine ranching system engineering. The construction of artificial reefs is beneficial to the improvement of marine land, the construction of marine ranch, the adjustment of marine industry structure, the promotion and optimization of marine industry, the development of marine tourism and related industries, the restoration and improvement of marine ecological ...

AI Technical Summary

Problems solved by technology

But above-mentioned artificial fish reefs of these prior art all have certain deficiency more or less: the shortcoming of such as common reinforced concrete: steel bar is easy to corrode, causes concrete to crack, collapses at last, therefore, general common reinforced concrete fish reef only has two The lifespan is about ten years, and the lifespan is short; in addition, the old tire reefs have certain pollution to the water body, while the steel reefs affect the seabed environment

[0004] In addition, the patent application of CN201710213373.0 discloses a method of making artificial fish reefs by using the housing frames to be demolished. The abandoned house frames are used as artificial fish reefs. Although the abandoned house frames can be fully utilized, environmental pollution and land occupation problems can be reduced. , but this kind of artificial reef is heavy and difficult to salvage and repair. Once it sinks, it is difficult to move again.
