In recent years, the environmental consciousness of people and be remarkably reinforced healthy pursuit, to the Safety and Environmental Protection of living environment
Require more and more higher.Inner wall of building face temperature be 23 DEG C～38 DEG C, under conditions of relative humidity is 85%～100%, easily
Growing and multiply mycete, the coating later by mold corrosion being faded, being stain so that coming off.It is local in southern area and humidity,
Inner wall of building the most all can use antibiotic paint brushing wall, realizes sterilization with antibacterial.Existing antibiotic paint mainly adds
Added the coating of inorganic antiseptic, discharged outside the aseptic antibacterial of the strong toxicities such as mercurous, lead, the more commonly used is containing copper or
The inorganic antiseptic of person's anion, the antibacterial color containing copper is relatively deep, the more difficult allotment of color, and anionic inorganic antibacterial
Because of advantages such as it are nontoxic, colourless, bacteriostasis is strong, it is widely used in antibiotic paint, but when this antibiotic paint meets water,
Silver ion therein easily separates out, thus shortens antibacterial expiry date.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of antibacterial inner wall paint, this method can solve existing antibacterial
The problem that coating exists Durability of antimicrobial effect difference.
In order to solve the problems referred to above, the technical solution used in the present invention is: the preparation method bag of this antibacterial inner wall paint

(3) hydroxyethyl cellulose solution, dispersant, defoamer it are subsequently added into, under the mixing speed of 500～600 revs/min,
Stir 1～2 hour；
(4) under agitation adding nano-bentonite, Pulvis Talci, mix homogeneously, sand milling to fineness is less than or equal to 45um；
(5) in step (4) gained slurry add styrene-acrylic emulsion, coalescents, stir 2～3 hours, mixing speed be 500～
650 revs/min；
(6) it is eventually adding thickening agent, under the mixing speed of 1000～1200 revs/min, after stirring 1～2 hour, filters out
Material.
In the technical scheme of the preparation method of above-mentioned antibacterial inner wall paint, more specifically technical scheme is it may also is that phenylpropyl alcohol
The hydroxyethyl cellulose solution of emulsion 24.9,4% 12.8 parts, nano silver antimicrobials 5 parts, hydroxyapatite 15.8, nano-bentonite
8 parts, Pulvis Talci 17.6,2-(4-thiazole) benzimidazole 0.6 part, thickening agent 1.1, dispersant 0.1, defoamer 2.8, coalescents
0.8, deionized water 28.
Further, described dispersant is polyacrylic acid dipersant.
Further, described defoamer is organic silicon defoamer.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that this method is former
The addition sequence of material and corresponding Parameter Conditions, can improve the dispersibility of coating and the stability of quality, thus effectively extend anti-
Bacterium persistency, obtained coating antibiosis stable performance, antibiotic rate reaches more than 99.5%, antibacterium endurance quality >=99.9%,
Antifungal endurance quality reaches 0 grade of HG/T3950-2007 standard；Nano silver antimicrobials is to escherichia coli, gonococcus, trachoma clothing
The tens of kinds of pathogenic microorganism such as substance have strong suppression and killing action, and will not produce drug resistance；2-(4-thiazole)
The Anti-mildew capability of benzimidazole is fine, and safety is high, Heat stability is good；Hydroxyapatite is inorganic carrier, and silver ion is not
It is easy to run off, by slow releasing function to improve antimicrobial long-acting.
