Description

A kind of antibiotic paint

Technical field

The present invention relates to paint fields, having antibacterial and sterilizing function antibiotic paint more particularly to a kind of.

Background technology

Antibiotic paint refers to the antiseptic that has antibacterial functions by addition and can be stabilized in film, through certain work There is the coating of sterilization and bacteria resistance function made of after skill processing.When antibiotic paint is used for public place, can reduce public The bacterial number in place reduces the probability of cross-infection and contact infection；It can then be effectively reduced furniture etc. for home environment Bacterial density on article optimizes the living environment of people.Presently commercially available coating is mostly organic substance fungicide with fungicide, These fungicide, to the same toxic side effect of the mankind, endanger the health of the mankind while killing microorganism.It is inorganic in recent years to receive Rice fungicide is increasingly becoming new developing direction.Current existing inorganic fungicide has nano-titanium dioxide, nano phase ag_2 o etc., And metallic silver is expensive, and silver ion is easily transformed into the silver oxide or black elemental silver of brown, not only reduces coating Anti-microbial property also limits its application in white or light-colored coating.

Invention content

There is antibacterial and sterilizing function antibiotic paint the object of the present invention is to provide a kind of.

The antibiotic paint is grouped as by the group of following parts by weight：

0.1~0.3 part of gallium oxide, 0.3~0.6 part of aluminium polychloride, 0.4~0.8 part of dispersant, antifoaming agent 0.2~0.4 Part, 5~10 parts of kaolin, 5~10 parts of titanium dioxide, 40~50 parts of coarse whiting, 0.1~0.2 part of 2-amino-2-methyl-1-propanol, at 1~2 part of film auxiliary agent, 0.4~0.8 part of propylene glycol, 0.1~0.2 part of preservative, 10~20 parts of lotion, surplus is water.

Preferably, acquisition is made by the steps in the gallium oxide：

(1) gallium nitrate solution of 6~10mmol/L is mixed in equal volume with the sodium acetate of 0.5~1.0mmol/L, adds ammonium hydroxide Adjust PH to 8~10, the cooled to room temperature after isothermal reaction 10h at 130~170 DEG C；

(2) reaction product that step (1) obtains is filtered, the solid obtained after filtering uses water and absolute ethyl alcohol to hand over again For rinsing repeatedly for several times, cryogenic vacuum is freeze-dried later, and gallium oxide presoma is made；

(3) the gallium oxide presoma that step (2) obtains at 600~900 DEG C is roasted into 3~5h after annealings and obtains oxidation Gallium powder.

In addition, the present invention also provides a kind of preparation method of antibiotic paint, it is specific as follows：

Aluminium polychloride is slowly added in water, is allowed to fully dissolve；Dispersant, antifoaming agent, kaolinite are sequentially added later Soil, titanium dioxide, coarse whiting and a small amount of water, sequentially add 2- amino -2- first at dispersion a period of time after system is uniformly dispersed Base -1- propyl alcohol, coalescents, gallium oxide, propylene glycol, preservative and antifoaming agent, dispersion a period of time, the system of waiting for is uniformly dispersed After add lotion and suitable water, obtain antibiotic paint product after disperseing a period of time.

The stir process of different rates can be aided in the adding procedure of above-mentioned each component, while supplementing suitable water to promote Into the dissolving and dispersion of component.

The antibiotic paint that technical solution obtains through the invention has the following advantages that：(1) have to various bacteria very strong It kills and inhibiting effect, fungistatic effect is more preferable than nano-titanium dioxide；(2) antibiotic paint and nano phase ag_2 o provided by the invention Equal silver system's antibiotic paint is lower compared to cost；(3) gallium oxide in antibiotic paint be transparent oxide material, can to avoid because Discoloration problem occurs for illumination, oxidation.In addition, the preparation method of antibiotic paint provided by the invention is with simple for process, inexpensive And the advantages of low power consuming.

Specific implementation mode

Technical solution of the present invention is described in detail with reference to specific embodiment.

1. the preparation of gallium oxide：

(1) by the sodium acetate of the gallium nitrate solution of 10mmol/L and 0.8mmol/L in ptfe autoclave medium body Product mixing, adds ammonium hydroxide to adjust PH to 10, cooled to room temperature after isothermal reaction 10h at 170 DEG C；

(2) reaction product that step (1) obtains is filtered, the solid obtained after filtering uses water and absolute ethyl alcohol to hand over again For flushing three times repeatedly, cryogenic vacuum is freeze-dried later, and gallium oxide presoma gallium oxide hydroxide is made；

(3) the gallium oxide presoma that step (2) obtains is roasted into 3 after annealings in Muffle furnace at 600 DEG C and obtains oxidation Gallium powder.

2. the preparation of antibiotic paint：

With the total weight number of coating system for 100, the additive amount of each component is indicated with relative weight part in system.It is whole A preparation process is aided with stirring always.

(1) 0.3~0.6 part of aluminium polychloride is slowly added in 15~25 parts of water, the stir speed (S.S.) in adding procedure is 200~600r/min；Stir speed (S.S.) is adjusted to 800~1000r/min after addition, stirring to aluminium polychloride is dissolved；
