Embodiment 1

[0023] Step 1: Add Maya blue to sulfuric acid with a mass fraction of 0.5%, heat it in a water bath at 60°C for 18h, then repeatedly suction filter and wash until neutral, after drying, crush it to 100 mesh, and calcinate it in a muffle furnace at 100°C for 1h , to obtain modified Maya blue;

[0024] Step 2: Mix aloe vera, pothos, milanum, spider plant, cactus, ivy, rose, camellia and daisy in equal proportions, cut and mash, inoculate 4wt% probiotics, probiotics include Bacillus sourbacillus and Bifidobacterium, and After anaerobic fermentation at 25°C for 10 days, filter the fermentation broth with a 25um microporous membrane to obtain plant enzymes;

[0025] Step 3: Mix 25% tin oxide, 30% zirconium dioxide, and 40% titanium dioxide evenly under the condition of filling argon, dissolve them in tartaric acid with a mass fraction of 50%, then add 5% lanthanum oxide, and use 20W power, Ultrasonic dispersion at an ultrasonic frequency of 40KHZ for 10 minutes to prepare a lantha...

Embodiment 2

[0029] The operation is the same as in Example 1, the difference is that step 1: the mass fraction of sulfuric acid is 0.75%, the water bath temperature and time are 70°C and 21h, the crushing particle size is 110 mesh, the calcination temperature and time are 110°C and 1.5h, step 2: prebiotic The inoculum amount of bacteria is 5wt%, the probiotics include Bacillus natto, Bifidobacterium, Lactobacillus rhamnosus, the number of days of fermentation is 13 days, the pore size of the microporous membrane is 30um, step 3: tin oxide, zirconium dioxide, titanium dioxide, The weight percentage of lanthanum oxide is 30%, 32%, 30%, 8%, the mass fraction of tartaric acid is 55%, the ultrasonic frequency, power, and processing time are 45KHZ, 22W, and 13min; step 4: tea polyphenols, quercetin, carbonic acid The weight ratio of hydrazine is 1:1.4:0.4, and the coating agent and the addition amount are glucoside and 40wt% in sequence; Step 5: the weight parts of modified Maya blue, plant enzy...

Embodiment 3

[0031] The operation is the same as in Example 1, the difference is that step 1: the mass fraction of sulfuric acid is 1%, the water bath temperature and time are 80°C and 24h, the crushing particle size is 120 mesh, the calcination temperature and time are 120°C and 2h, step 2: probiotics The inoculation amount is 6wt%, the probiotics include Bacillus natto, Bifidobacterium, Lactobacillus rhamnosus, yeast, the fermentation days are 15 days, the pore size of the microporous membrane is 35um, step 3: tin oxide, zirconium dioxide, titanium dioxide , the weight percentage of lanthanum oxide is 35%, 35%, 20%, 10%, the mass fraction of tartaric acid is 60%, the ultrasonic frequency, power, and processing time are 50KHZ, 25W, and 15min; Step 4: tea polyphenols, quercetin, The weight ratio of hydrazine carbonate is 1:1.6:0.5, the coating agent and the addition amount are hydroxypropyl-β-cyclodextrin, 50wt%; step five: modified Maya blue, plant enzyme, lanthanum-doped composite photoca...

Abstract

The invention discloses a preparation method of a bacteriostatic air purifier. The preparation method comprises the following steps: step I: acid leaching, calcining, and producing modified maya blue;step II: fermenting various plants by virtue of probiotics, filtering a fermented solution, and preparing plant enzymes; step III: under a condition of argon charged, dissolving zirconium dioxide andtitanium dioxide in tartaric acid, and then preparing a lanthanum-doped composite photocatalyst by virtue of the coupling bonding of lanthanum oxide; step IV: mixing tea polyphenols, quercetin and hydrazine carbonate according to a weight ratio of 1: (1.2 to 1.6): (0.3 to 0.5), condensing by using a coating agent, and preparing a coated synergist; and step V: mixing 20 to 30 parts of modified maya blue, 40 to 60 parts of plant enzymes, 12 to 16 parts of lanthanum-doped composite photocatalyst, and 15 to 20 parts of coated synergist, thus obtaining the air purifier. By adopting the preparationmethod, the pathogenic bacteria can be effectively eliminated, the air spreading route of the pathogenic microorganism can be blocked, the air pollutants can be effectively degraded, and the air quality can be improved.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a preparation method of an antibacterial air purifier. Background technique [0002] Air purifiers mainly include three types: adsorption type, covering type and decomposition type. Adsorption air purifiers use the principle of physical adsorption and chemical attachment to separate harmful pollutants in the air. Common ones include activated carbon, alumina, negative ions, molecular sieves, etc. , Covering-type air purifiers use the odor and odor covered by aromatic hydrocarbons. Common ones include plant essences, condensate fragrance boxes, etc. Decomposition-type purifiers use the principle of decomposing and complexing to degrade harmful components in the air and completely remove odors. Common There are titanium dioxide, cadmium sulfide and so on. Compared with adsorption-type and cover-type air purifiers, decomposition-type purifiers have better perfo...
