Description
One, technical field
The present invention relates to antimicrobial form polyester-epoxy powder coating of a kind of inorganic nano combined antiseptic-germicide modification and preparation method thereof, belong to the preparation field of powder coating.
Two, background technology
United States Patent (USP) 5759746, Fabrication process using a multi-layer antireflective layer, reported on semiconductor integrated circuit board a kind of assembling anti-reflection coating technology of having added nano silicon of preparation, this technology mainly is a kind of protective layer for preventing that some semiconductor integrated circuit boards are provided with the influence of circuit card etching performance such as semiconductor memory, photoetching technique middle-ultraviolet lamp; Chinese patent CN1228107A, the making method that germ resistance powder coating, the electric furnace that has used this coating and germ resistance are filmed, reported and had resinous principle and on silicon-dioxide, be loaded with the preparation method of the powder coating that possesses germ resistance that thiosulfate anion closes the antiseptic-germicide of silver complex, this technology mainly is when the formation of coating germ resistance powder coating is filmed, antiseptic-germicide is embedded in the inside of filming, even contacting seldom of antiseptic-germicide and bacterium, can suppress the breeding of bacterium, but this technology is not reported the variable color situation in this germ resistance powder coating use yet.Chinese patent CN1270193A, a kind of manufacture method of antibiotic paint, reported a kind of preparation method of antimicrobial form interior wall coating, by this technology prepare that antimicrbial power is strong, has a broad antifungal spectrum, washable long-acting, nonvolatil and the antibiotic paint that has no side effect with antibacterial, the cost that this patent is not pointed out to add behind the antimicrobial component increases situation.Open east, research on the antibiotic coagulation, New Building Materials, 2002, (4): P13-14, after having compared the antibacterial ability of rare earth compound cerous nitrate and silver ion antimicrobial agent, choose cerous nitrate and mix its antibiotic level of test in the cellular concrete, the result shows: the antibacterial ability and the silver ion antimicrobial agent of cerous nitrate are similar; The antibiotic level that is mixed with the cellular concrete of cerous nitrate is improved largely; Li Bingchao, pair Tian Xia, the preparation and the anti-microbial activity thereof of Ce-norfloxicin title complex, Liaoning chemical industry, 2000, (6), P341-343, synthesized new Ce-norfloxicin title complex, measured title complex to causing the minimum inhibitory concentration of burn infection main bacteria seed with the double dilution method of test tube.The result shows that Ce-norfloxicin title complex is water-soluble, and is fat-soluble good.Ce-norfloxicin title complex will be better than norfloxicin slightly to the anti-microbial activity of Pseudomonas aeruginosa, and to intestinal bacteria, the anti-microbial activity of golden yellow staphylococcus is similar to norfloxicin; Yan Yurong, Zhao Yaoming, inorganic antibacterial material, chemical industry progress, 2001, (7), P5-9, point out that the deficiency of resistance toheat can adopt mode organic and/or inorganic and that hydroaropic substance is composite in order to overcome the limitation and the easy wash-out of organic antibacterial agent of the anti-mattress spectrum of inorganic anti-bacterial agent.The intrinsic anti-mattress activity of organic and inorganic anti-bacterial agent etc. may strengthen significantly in compound system, obtains high anti-mattress performance under the situation of few additive, but does not see this experiment in the article; Song Linyong, Xu Wanjun, nano antibacterial agent and the application in powder coating thereof, coatings industry, 2002, (3), P32-34 has studied at epoxy/polyester, add 1%～3% inorganic silver ion antimicrobial agent in polyester/TGIC powder systems after, adopt original powder manufacturing apparatus and electrostatic painting process, the coating that forms has the function of good kill bacteria, and coating itself is harmless, but does not provide the variable color situation after coating is used.
Three, summary of the invention
Antimicrobial form polyester-epoxy powder coating of a kind of inorganic nano combined antiseptic-germicide modification that provides at the deficiencies in the prior art and preparation method thereof is provided, be characterized in existing polyester-epoxy powder coating, introducing inorganic nano combined antiseptic-germicide, give polyester-epoxy powder coating antibacterial, do not reduce performances such as polyester-epoxy powder coating sticking power, snappiness, shock strength, slickness, hardness and chemical resistant properties simultaneously.
The present inventor finds that nano titanium oxide has certain effect to improving the powder coating germ resistance, but the existence that needs UV-irradiation, oxygen or water just can be played germicidal action, but can not obtain satisfied antibacterial effect; And organic antibacterial agents such as common quaternary antiseptic-germicide have poor heat resistance, easily decompose and shortcoming such as work-ing life is short, common inorganic antiseptic majority contains silver ions, easily be transformed into brown silver suboxide or be reduced into black simple substance silver through ultraviolet catalyzed, variable color has not only reduced its anti-mattress, but also restricted its is applied in white or the light-coloured coating and goes, and use silver-colored cost height in a large number, restricted it in wider application.Therefore, it be carrier by loading cheap cerium is to obtain inorganic nano combined antiseptic-germicide behind the ion that the present invention adopts the multi-hole type nano titanium oxide, add in the epoxide powder coating with suitable amount, increased substantially the anti-microbial property and the integrated performance index of polyester-epoxy powder coating.
Purpose of the present invention is realized that by following technical measures wherein said raw material umber is parts by weight except that specified otherwise.
The recipe ingredient of the antimicrobial form polyester-epoxy powder coating raw material of composite nano germicide modification is:
