Description
Technical field
The present invention relates to response type ultraviolet absorption agent, specifically is a kind of triazines ultraviolet absorber and synthetic intermediate and application that contains the response type of quaternary ammonium salt group.
Background technology
Entered since 20th century, a large amount of uses along with carbon fluorine series solvent and fluorine Lyons, a large amount of halide is trapped in the air sky, formed active halogen by ultraviolet light degradation, they so chain reaction takes place with ozone, cause the atmospheric ozone layer heavy damage, the ultraviolet ray that arrives ground is increased thereupon, the influence that the mankind are produced obviously increases.Because the minimizing of ozone layer concentration, the short wavelength ultraviolet that is radiated ground in the sunshine increases.Torrid areas particularly, solar radiation power is strong, if fabric is thin, then ultraviolet ray makes skin produce color spot, and may bring out canceration.Since the seventies, the report that white people residential areas such as Australia, the U.S., Canada, Europe have the cutaneum carcinoma incidence of disease to increase progressively in succession.
Wear very little clothes summer, and ultraviolet radiation sees through easily and makes the excessive ultraviolet ray irradiation of human body acceptance cause skin injury, even produce cutaneum carcinoma.As COTTON FABRIC, good permeability strong, the no static, comfortable and easy to wear of one of the most frequently used lining in summer, favored deeply with its hygroscopicity.But it is compared with other textile materials, and ultraviolet ray transmissivity is higher, the ultraviolet radiation preventing poor-performing, and on the market anti UV finishing agent at present is not because possess reactive functional groups, the fastness of arrangement back fabric is not very good.Therefore, exploitation is a kind of is applicable to that the anti UV finishing agent of COTTON FABRIC is very significant.
Summary of the invention
The object of the present invention is to provide a kind of triazines ultraviolet absorber and synthetic intermediate and application that contains the response type of quaternary ammonium salt group.The present invention is a parent with three polychlorostyrene piperazines, and quaternary ammonium salt is building up on the triazine parent, has obtained the ultraviolet absorber of response type; Because the existence of quaternary ammonium salt structure when the ultraviolet absorber of gained has uvioresistant performance, has also possessed antibacterial functions.
The present invention relates to a kind of response type ultraviolet absorption agent, its general structure as the formula (1):

Described ultraviolet absorber can prepare according to the following procedure:
(1) the nitro thing is synthetic: 1-(end position halogen-alkoxyl)-4-nitrobenzene 5g is added in the reactor, add the tertiary amine 3g or the 3g above (tertiary amine double as reaction dissolvent) of group A part, 20~80 ℃ of reaction 2~18h; Adopt cyclohexane or n-hexane washing crude product, obtain the nitro thing;
(2) the amido thing is synthetic: nitro thing 7g, be dissolved in 30~150ml absolute ethyl alcohol, and it is in 36% concentrated hydrochloric acid that 8.5~30g stannous chloride is dissolved in 9~35g weight concentration, above-mentioned solution is under agitation dropped in the ethanolic solution of nitro thing, after 20~70 ℃ reaction 4~20h reaction finishes down, reduce to room temperature, add the 30%NaOH aqueous solution, transferring PH is 8~10, filters, and filtrate decompression obtains crude product, add anhydrous alcohol solution again, leach undissolved salt, ethanol is removed in decompression, obtains the amido thing.
(3) ultraviolet absorber is synthetic
Stir down and add three polychlorostyrene piperazine 0.4g in frozen water, group B 0.2~0.8g is added in the reactor, controlling reaction system PH with 10% sodium carbonate in the course of reaction is 6~7, react 2~4h down at 0~5 ℃, one contracts after reaction finishes, the aqueous solution of the amido thing of group A0.2~0.9g is added dropwise in the reaction system, and the PH of reaction system is 7~7.5, at 30~60 ℃ of reaction 4~10h down.After reaction finishes, filter, obtain crude product.Crude product adds the methyl alcohol dissolving, leaches insoluble matter, and decompression steams methyl alcohol, obtains ultraviolet absorber.
Described response type ultraviolet absorption agent is mainly used in the anti UV finishing of COTTON FABRIC.Its structure of response type ultraviolet absorption agent of the present invention is similar to REACTIVE DYES, therefore can carry out anti UV finishing to COTTON FABRIC according to the technique for applying of traditional REACTIVE DYES.In application process, under the condition of salt-free alkali-free, dye-uptake can reach more than 70%.Fabric after the arrangement has good washability.
The present invention has following advantage:
(1) ultraviolet absorber that the present invention relates to has the response type group in its structure, can combine with chemical bond with COTTON FABRIC, fabric fastness after the arrangement is good, have good water-wash resistance, after through the washing more than 30 times, anti-ultraviolet effect does not almost change.
(2) uvioresistant is effective after the textile finishing.When the response type ultraviolet absorption agent that the present invention relates to was used, use amount was 0.5% (o.w.f.), and TUV-B is 1.2%.
(3) technique for applying is simple.The technique for applying of the response type ultraviolet absorber that the present invention relates to can carry out anti UV finishing to cotton under the condition of salt-free alkali-free.
(4) the response type ultraviolet absorber that the present invention relates to has the anti-microbial property of wide spectrum.The aqueous solution of ultraviolet absorber is the gram-positive bacteria of representative and Gram-negative bacteria is killed or inhibitory action to staphylococcus aureus and Escherichia coli.
