Abstract
The invention relates to paint for killing off bacteria in air, in particular to paint for killing off bacteria and fungi. The paint is prepared through the following steps of: taking fermentation extract of penicillium notatum; adding methacrylate, kaolin, cellulose derivative, acrylic acid-base resin, rape oil, hydroxypropyl methyl cellulose, calcium propionate, propyl gallate, acetyl triethyl citrate and H2O2 into the fermentation extract in sequence to obtain mixed solution; next uniformly stirring the obtained mixture by using a stirring machine; standing for 1-2 days until the mixture becomes sticky; electrifying the mixture until a layer of foam is formed on the surface of the mixture; and finally, scraping off the foam layer on the surface by using a scraper and washing the mixture with ultrasonic wave to obtain a paint layer. The paint has good absorption, good sterilization capacity and no toxicity and is suitable for large-range promotion.
Description
Technical field
The present invention relates to a kind of coating of killing bacterium in the air, relate in particular to the coating of a kind of kill bacteria and fungi.
Background technology
Current Chinese environmental pollution has surpassed barrier line, especially air, water, carbon dust, radiation and toxic substance and has encroached on our health constantly, and the pollution of indoor environment is even more serious.The Along with people's growth in the living standard; It is universal day by day during air-conditioning is lived in modern times; Yet it can cause human body, room and the air conditioning machinery recycle system in a sealing of indoor formation, as easy as rolling off a log mikrobes such as bacterium, virus, mould is multiplied in a large number, influences human health.
To this situation, the someone has invented out a kind of fungicidal paint, kills airborne bacterium through the coating on the room wall.But itself containing antimildew disinfectant in this coating, is deleterious, in kill bacteria, can evaporate into toxic substance in the air, influences human health.To this situation; Someone improves it; For example publication number is CN1445312, and it is photocatalyst that name is called " have self-cleaning, anti-mildew, the aqueous functional coatings of the effect of sterilizing and purify air " said in traditional coating, adding with the nano-anatase titanium oxide, is aqueous binders with water soluble resin or polymer emulsion or silicon sol and their mixture; Under UV-irradiation, cause photocatalysis, kill bacteria.This kind method is killed airborne bacterium through photocatalysis; Avoided in coating, adding Toxic matter cleverly, not only killed bacterium but also can not influence human beings'health, but this kind method has needed the irradiation of UV-light; This has just limited it in indoor widespread adoption, is difficult to be applied to practice.
Summary of the invention
The present invention is directed in traditional fungicidal paint and add antimildew disinfectant, but this kind sterilant often itself has very big toxicity, influences human health.And improved fungicidal paint needs the katalysis of ultraviolet light, and restricted condition is high, is difficult to the problem that is applied to put into practice.Proposed a kind of coating of killing bacterium in the air, can kill airborne bacterium and fungi by active adsorption, can not exert an influence simultaneously human health with this coating.
In order to achieve the above object, the technical scheme of the present invention's employing is
(1) gets the fermentation vat liquor of penicillium spp;
(2) be under 35～40 ℃ of conditions in temperature, successively to wherein adding methacrylic ester, kaolin, derivatived cellulose, propylene soda acid appearance resin, rape oil, Vltra tears, calcium propionate, gallic acid third lipoprotein, ATEC, H
2O
2, get mixing solutions;
(3) stir the mixture that obtains with stirrer, left standstill 1～2 day, treat that its one-tenth is thick;
(4) to the mixture energising, till mixture surface formation one deck foam;
(5) strike off the surfactant foam layer with scraper plate, with UW mixture is washed at last, obtain dope layer.
Described kaolin is 800～900 orders.
Described coating is 30%～35% methacrylic ester by mass percentage, 2%～5% kaolin, 2%～4% derivatived cellulose; 3%～5% propylene soda acid holds resin, 0.3%～1% rape oil, 3%～5% Vltra tears; 0.5%～2% calcium propionate; 3%～5% gallic acid third lipoprotein, 2%～4% ATEC, 35%～40%H
2O
2, 5%～10% penicillium mould.
Principle of the present invention be with methacrylic ester as aqueous binders, as filler, as solvent, obtain coating with kaolin to wherein adding various auxiliary materials with ydrogen peroxide 50, under the effect of electric current, make the ydrogen peroxide 50 electrolysis in the coating obtain O then
3And O
2 -, combine with a large amount of free-OH group in the coating, obtain a kind of strong oxidizing property material, magnetoresistive effect also makes the adsorptivity of coating strengthen simultaneously.After bacterium was adsorbed on the coating, cell walls is synthetic under the effect of penicillium mould was suppressed, then the oxygenolysis and then cause bacterium and the death of fungi under the effect of strong oxidizing property group of the phosphatide in cytolemma.
Beneficial effect of the present invention is:
(1) penicillium mould and O in the coating
2 -Nontoxic, can not damage the mankind;
(2) bacteriocidal substance directly acts on cell walls and cytolemma, can effectively kill various mikrobes;
(3) the existing good adsorption property of the magnetic coating that obtains has good sterilizing ability again.
