Embodiment 1

[0071] A commercially available common pottery pot is used, which is made of aluminum oxide and silicon oxide as main raw materials, and also contains a small amount of magnesium oxide. The average pore diameter is 0.2 μm, and the porosity is 30%.

[0072] First, put the ordinary pottery pot in water to clean it, then take it out and dry it at 110°C; use ethanol as solvent, trimethylchlorosilane ((CH3) 3Si-Cl) is formulated into the mixture that the volume molar concentration range of organosilane is 10mmol / L;

[0073] Next, soak the dried clay pot in the above-mentioned ethanol solution of trimethylchlorosilane, and place it at room temperature for 2 hours;

[0074] Take it out and dry it at 120°C for 2 hours. A pottery basin with anti-permeation gas particles on the inner and outer surfaces is obtained.

[0075] In this embodiment, the ethanol solution of trimethylchlorosilane can also be directly poured into a pot for soaking. The schematic diagram of the structure of t...

Embodiment 2

[0080] A commercially available common pottery pot is used, which is made of alumina and silicon oxide as main raw materials, and also contains a small amount of iron oxide. The average pore size is 1 μm and the porosity is 40%.

[0081] First, put the ordinary pottery pot in water to clean it, then take it out and dry it at 110°C; use ethanol as solvent, dimethylhexadecylchlorosilane ((CH3) 2 C 16 h 33 Si-Cl) is formulated into the mixture that the volume molar concentration range of organosilane is 30mmol / L;

[0082] Next, soak the dried clay pot in the above-mentioned ethanol solution of dimethylhexadecylchlorosilane, and place it at room temperature for 2 h;

[0083] Take it out and dry it at 120°C for 2 hours. A pottery basin with anti-permeation gas particles on the inner and outer surfaces is obtained.

[0084] Carry out the contact degree test on the prepared pottery basin, such as Figure 3b shown. The contact angle photos of ordinary pottery basins are as foll...

Embodiment 3

[0088] A commercially available common pottery pot is used, which is made of alumina and silicon oxide as main raw materials, and also contains a small amount of iron oxide. The average pore diameter is 10 μm, and the porosity is 50%.

[0089] First, put the ordinary pottery pot in water to clean it, then take it out and dry it at 110°C; use ethanol as solvent, and organic silane (C 3 h 7 ) 2 (C 2 h 4 CH=CH 2 ) Si-OCH 3 The volume molar concentration scope that makes organic silane is the mixture of 50mmol / L;

[0090] Next, soak the dried clay pot in the above-mentioned ethanol solution of organosilane, and place it at room temperature for 2 h;

[0091] Take it out and dry it at 120°C for 2 hours. A pottery basin with anti-permeation gas particles on the inner and outer surfaces is obtained.

[0092] The air permeability test was carried out, and after 20 hours of treatment, the oxygen content of the water in the anti-permeation gas pottery basin was 7.80 mg / L.

Abstract

The invention relates to the field of bonsai planting, in particular to a pottery basin with breathable and impermeable effects. Impermeable and breathable particles are arranged on the inner wall of the impermeable and breathable pottery basin. The preparation method comprises the following steps of applying a mixture with organosilane and solvent to the inner wall surface of the pottery basin; and performing grafting reaction on the mixture so as to obtain the impermeable and breathable pottery basin. The surface of the impermeable and breathable pottery basin is not wetted by water, so that micropores in the impermeable and breathable pottery basin are not blocked, external air can enter the basin through the micropores, and the breathing performance of the bonsai container is guaranteed. Moreover, the impermeable and breathable pottery basin has water retention, fertilizer maintenance and breathing effects simultaneously.

Description

technical field [0001] The patent of the present invention relates to the field of potted planting, in particular to a pottery pot with breathable and water-proof effects. Background technique [0002] For people living in the city, in a highly stressed state and in a polluted air environment, building a green home and office environment by growing plants, fruits and vegetables indoors is a way to reduce stress and improve the quality of life . Indoor potted plants not only allow people to experience the fun of the whole cultivation process, but also beautify the environment and purify the indoor air. Most of the existing potted pots on the market are based on plastic pots, glass pots and porcelain pots. Since these pots do not have air permeability, drainage holes are usually provided at the bottom to increase the air permeability of the pots. However, when watering, the water is quickly discharged before wetting the soil, and the root system of the potted plants not only...
