Problems solved by technology

[0006] The technical problem to be solved by the present invention: Aiming at the problem that the existing air conditioners cannot filter fine particles, and it is difficult to effectively filter, inhibit or kill free harmful ions and various harmful bacteria in the air, an antibacterial The preparation method of the self-cleaning air-conditioning filter element material, the method first smears loach on the body with sodium chloride, stimulates its epidermis to produce more mucus, then takes its epidermis, then pulverizes and homogenates, and then ultrasonically extracts, enzymatically hydrolyzes, and ultrasonography Membrane filtration, impurity removal, to obtain antimicrobial peptides, loach epidermis and its secreted mucus contain a large amount of antimicrobial peptides, take Sargassum to dry, crush and sieve, and then treat with hydrochloric acid to make it dead, the treated Sargassum is The cell wall is more broken, and more internal functional groups are exposed to combine with metal ions. The effect of treating heavy metals is better. After the activated carbon fiber is crushed and sieved, it is mixed with antimicrobial peptides and treated sargassum to obtain the base material, and then mixed with even Mixing agent, xanthan gum, etc., hot pressing in the mold and demoulding to obtain antibacterial self-cleaning air conditioning filter material

example 1

[0020] First select 3 loach with a length of 10cm, place them in a container, take sodium chloride and apply it evenly on the surface of the loach twice, control the amount of sodium chloride to 4g each time, and the time interval is 1h, to stimulate the loach to wriggle and secrete mucus 30 minutes after the last smearing, the loach was dissected, its epidermis was taken and added to a beaker, and 500 mL of sodium dihydrogen phosphate-sodium hydroxide buffer solution with a pH of 7.4 was added to the beaker, and then placed in a high-speed tissue masher , homogenate at 6000r / min for 30min, and pulverize sufficiently to obtain a homogenate; place the above homogenate in an ultrasonic oscillator, extract ultrasonically at 230W and 40°C for 30min, then transfer to an enzymolysis tank, and then add 0.3g of Protease, hydrolyze at 45°C for 3 hours, after the hydrolysis is complete, collect the hydrolyzate and put it in a centrifuge, centrifuge at 4000r / min for 20min, collect the sup...

example 2

[0023]First select 5 loaches with a length of 15cm, place them in a container, take sodium chloride and apply it evenly on the body surface of the loach 4 times, control the amount of sodium chloride to 6g each time, and the time interval is 2h, to stimulate the loach to wriggle and secrete mucus 40 minutes after the last smearing, the loach was dissected, its epidermis was taken and added to a beaker, and 600 mL of sodium dihydrogen phosphate-sodium hydroxide buffer solution with a pH of 7.6 was added to the beaker, and then placed in a high-speed tissue masher , homogenized at 8000r / min for 40min, and thoroughly pulverized to obtain a homogenate; put the above homogenate in an ultrasonic oscillator, ultrasonically extract at 250W and 50°C for 40min, then transfer it to an enzymatic hydrolysis tank, and then add 0.5g of Protease, hydrolyze at 55°C for 4 hours, after the hydrolysis is complete, collect the hydrolyzate and put it in a centrifuge, centrifuge at 6000r / min for 30mi...

example 3

[0026] First select 4 loach with a length of 13cm, place them in a container, take sodium chloride and apply it evenly on the body surface of the loach 3 times, control the dosage of sodium chloride to 5g each time, and the time interval is 1.5h, to stimulate the loach to wriggle and secrete Mucus, 35 minutes after the last smear, dissect the loach, take its epidermis and put it into a beaker, add 550 mL of sodium dihydrogen phosphate-sodium hydroxide buffer solution with a pH of 7.5 into the beaker, and then place it in a high-speed tissue masher Homogenize at 7000r / min for 35min, and pulverize fully to obtain a homogenate; place the above homogenate in an ultrasonic oscillator, extract ultrasonically at 240W, 45°C for 35min, then transfer to an enzymolysis tank, and then add 0.4g Neutral protease, enzymolysis at 50°C for 3.5h, after the end of enzymolysis, collect the enzymolysis solution and put it in a centrifuge, centrifuge at 5000r / min for 25min, collect the supernatant, ...

Abstract

The invention relates to a preparation method of an antibacterial self-cleaning air conditioning filter element material, and belongs to the technical field of filter element material preparation. The preparation method comprises following steps: the bodies of misgurnus anguillicaudatus are smeared with sodium chloride so as to stimulate the epidermis of misgurnus anguillicaudatus to generate more mucus, and the misgurnus anguillicaudatus epidermis is collected, and is subjected to smashing, homogenating, ultrasonic extraction, enzymolysis, ultrafiltration membrane filtering, and impurity removing so as to obtain antibacterial peptide, wherein the epidermis of misgurnus anguillicaudatus and the muscus generated by the epidermis contain a large amount of the antibacterial peptide; scagassum is collected, dried, smashed, and sieved, and is treated with hydrochloric acid so as to kill the scagassum, wherein a lot of cell walls of the treated scagassum are broken, so that more internal functional groups are exposed, combination of the exposed internal functional groups with metal ions is realized, and better heavy metal treatment effect is achieved; activated carbon fiber is smashed and sieved, and is mixed with the antibacterial peptide and the treated scagassum so as to obtain a base material; the mixed material is mixed with materials such as a coupling reagent and xanthan gum, and an obtained mixture is delivered into a mould for hot pressing and demoulding so as to obtain the antibacterial self-cleaning air conditioning filter element material.

Description

technical field [0001] The invention relates to a method for preparing an antibacterial self-cleaning air conditioner filter element material, and belongs to the technical field of filter element material preparation. Background technique [0002] With the increase of urban pollution, it has become a high probability event that the PM2.5 content in the atmosphere exceeds the standard, and the PM2.5 content in the corresponding living room generally exceeds the standard. Since we stay in the living room for a longer time, how to effectively Reducing the content of PM2.5 in indoor space has become a very important topic in the field of air purification. [0003] At present, the method of filtering is usually used to solve indoor PM2.5 pollution. This method is also the method adopted by special indoor air purifiers and industrial clean rooms. However, the price of air purifiers that use filtering methods and achieve good filtering effects is generally expensive. [0004] The...
