Problems solved by technology

However, the cost of making fish tanks by processing natural stone is very high, and it is not suitable for promotion to ordinary families.
Moreover, among natural stones, stones with sparse textures have poor impermeability, while stones with dense textures have poor air permeability.
That is, it is difficult to meet the requirements of anti-seepage and air permeability at the same time
At present, there is no material with both impermeability and air permeability on the market that can replace stone to make fish tanks

Embodiment 1

[0068] figure 1 For the breathable fish tank of the present invention, the anti-permeation gas fish tank 1 has an open cavity, and the fish tank is covered with pores of 0.002-0.086mm formed between adjacent aggregate particles. The pores can allow gas molecules to pass through smoothly, and the hydrophobic properties of the hydrophobic binder can effectively prevent the penetration of liquid water molecules.

[0069] The aggregate particles are a mixture of quartz sand and slag at a weight ratio of 5:1, the particle size of the quartz sand is 0.02-0.1 mm, the particle size of the slag is 0.08-0.15 mm, and the hydrophobic binder contains Fluorine epoxy resin binder 2,2-bisphenol-based hexafluoropropane diglycidyl ether, hydrophobic binder and aggregate particles are used at a weight ratio of 1:49.

[0070] Described fish jar 1 is to make by following method:

[0071] a. Mix the aggregate particles with the hydrophobic binder and pour into the mixer to stir evenly;

[0072...

Embodiment 2

[0076] The air-permeable fish tank in this embodiment has an open cavity, and the fish tank is covered with pores of 0.003-0.065 mm formed between adjacent aggregate particles. The pores within this size range can allow gas molecules to pass through smoothly, and It can effectively prevent the penetration of liquid water molecules.

[0077] The aggregate particles are formed by mixing ceramsite and glass microspheres at a weight ratio of 3:1, the particle size of the ceramsite is 0.01-0.075 mm, and the particle size of the glass microspheres is 0.04-0.08 mm.

[0078] The hydrophobic binder is a silicon-containing epoxy resin binder diphenylsilane modified bisphenol A epoxy resin, and the hydrophobic binder and aggregate particles are used in a weight ratio of 3:97.

[0079] The aggregate particles are coated with hydrophobic epoxy resin, and the hydrophobic epoxy resin is 2wt% of the aggregate particles. The hydrophobic epoxy resin is a mixture of polyamide resin modified epo...

Embodiment 3

[0090] figure 1 It is a ventilating fish tank in this embodiment, which is a cavity with an opening formed by four side walls, front, rear, left, and right sides and a bottom wall, wherein the front side wall is made of transparent glass. The rest of the side wall and the bottom wall of the fish tank are covered with pores of 0.002-0.086 mm formed between adjacent aggregate particles. The pores within this size range can allow gas molecules to pass through smoothly, and can effectively prevent liquid water molecules through.

[0091] The aggregate particles are formed by mixing ceramsite and quartz sand at a weight ratio of 1:3, the particle size of the ceramsite is 0.02-0.045 mm, and the particle size of the quartz sand is 0.015-0.1 mm.

[0092] The hydrophobic binder is a silicone binder methylphenylpolysiloxane resin, and the hydrophobic binder and aggregate particles are used in a weight ratio of 3:97.

[0093] The aggregate particles are coated with hydrophobic polytet...

Abstract

The invention discloses an air-permeable fish tank. The fish tank comprises a cavity with an opening and is formed by bonding hydrophobic substance-coated aggregate particles and hydrophobic binder; voids, through which air molecules can pass through and liquid water molecules can not pass through under high pressure, are formed among adjacent aggregate particles; and diameters of the voids are of 0.002-0.086 mm. The invention also discloses a manufacturing method of the fish tank. The fish tank effectively solves the problem that existing ordinary fish tanks can not have both of anti-seepage and air-permeable performances. The fish tank has the advantages of low cost, simple manufacture and simple appearance, and it is suitable for various occasions suitable for fish culture.

Description

technical field [0001] The invention relates to a fish tank, in particular to a breathable fish tank. Background technique [0002] At present, various fish tanks are made of glass, ceramics, plastics and other materials on the market, providing consumers with a variety of choices, but the fish tanks made of these materials have no ventilation effect. If fresh water is not replaced in time to ensure sufficient oxygen, water Goldfish are hard to survive. [0003] In order to solve the above problems, Chinese patent CN101422138A discloses a fish tank, which is provided with a fountain in the fish tank, which can not only watch but also increase oxygen. It consists of a fish tank, a switch, a small water pump, a transparent pipe, and a power cord. It is characterized in that the switch is on the wall of the fish tank, the small water pump is at the bottom of the fish tank, the transparent pipe is set in the center of the fish tank and connected to the small water pump, and the...
