preparation example Construction

[0033] The preparation method of Artemisia annua extract is as follows: dry fresh Artemisia annua L. at 50°C for 48h, pulverize to 150 mesh to obtain Artemisia annua L. powder, then add 55wt% ethanol aqueous solution with 5 times the mass of Artemisia annua powder and supercritical extraction for 2.5h , The extraction pressure is 20MPa, the extraction temperature is 40°C, the separation pressure is 5MPa, and the separation temperature is 35°C to obtain the supercritical extract and the supercritical raffinate; then add 20 times the mass of the supercritical raffinate to the above supercritical raffinate The 60wt% methanol aqueous solution was placed in 55°C for 20min ultrasonic treatment, the ultrasonic power of the ultrasonic treatment was 400W, the ultrasonic frequency was 28kHz, to obtain the ultrasonic extract; the supercritical extract and the ultrasonic extract were combined, and filtered through 250 mesh The filtrate was filtered with cloth, and the obtained filtrate was ...

Embodiment 1

[0045] A filter material with sterilization function, prepared from the following parts by mass of raw materials: 100 parts of activated carbon, 10 parts of acrylic acid, 18 parts of oxalic acid, 1.5 parts of dodecyl dimethyl benzyl ammonium chloride, dichloromethane 3 parts of phenol, 2 parts of Artemisia annua extract, 2 parts of Patrinia vulgaris extract, 2 parts of Dendrobium extract, 5 parts of sodium hexametaphosphate, 75 parts of modifier, and 300 parts of distilled water.

[0046] The modifier is made by mixing expanded perlite, activated attapulgite, and diatomite in a mass ratio of 1:1:1.

[0047] The preparation method of the activated attapulgite is: adding 8wt% hydrochloric acid solution to the attapulgite at a mass-volume ratio of 1:8 (g / mL), soaking at 25°C for 10h, and then at 35°C, 6000r / Centrifuge for 20 minutes under the condition of min, remove the supernatant and dry to 7wt% at 100°C, then activate at 280°C for 15min, and finally ball mill for 3h in a ball mil...

Embodiment 2

[0054] It is basically the same as Example 1, except that the filter material with sterilization function is prepared from the following parts by mass of raw materials: 100 parts of activated carbon, 10 parts of acrylic acid, 18 parts of oxalic acid, and dodecyl dimethyl 1.5 parts of benzyl ammonium chloride, 3 parts of dichlorophenol, 3 parts of Artemisia annua extract, 3 parts of Patrinia vulgaris extract, 5 parts of sodium hexametaphosphate, 75 parts of modifier, and 300 parts of distilled water. The modifier is the same as in Example 1.

[0055] The preparation method of the filter material with sterilization function includes the following steps:

[0056] Ⅰ. Weigh each raw material component by mass;

[0057] Ⅱ. Mix dodecyl dimethyl benzyl ammonium chloride, dichlorophenol, Artemisia annua extract, Patrinia vulgaris extract, sodium hexametaphosphate, and distilled water at 60°C and an absolute pressure of 0.07MPa Next, stir for 30h at a speed of 200r / min to obtain a mixed solu...

Description

Technical field [0001] The invention relates to the technical field of environmental protection, in particular to a filter material with a sterilization function and a preparation method thereof. Background technique [0002] Water quality is a major focus of the people’s life and production foundation. At present, clean rooms in hospitals, pharmaceutical industry, food industry, microelectronics industry, fine chemicals, and high-precision instruments all use antibacterial filter materials with antibacterial function. A large number of microorganisms breed on the material, which not only causes pollution, but also the mycelium makes the filter material's permeation rate drop rapidly. In severe cases, it needs to be updated every six months. Therefore, it is very important to provide an antibacterial filter with high efficiency and long-lasting antibacterial properties. The bactericidal effect of silver was discovered by humans in ancient times. The use of silver tableware in C...
