Description
Technical field
The present invention relates to a kind of preparation method of bafta antibacterial finishing agent, especially a kind of bafta antibiotic finish
Agent, belongs to textile auxiliary agent field
Background technology
The species of bafta antiseptic is various, and different properties, sorting technique is also different.Structure according to anti-biotic material is come
Classification, can be divided into inorganic, the organic and class of biological antibiosis agent 3.Artificial synthesized anti-biotic material is divided into inorganic and organic two big class.
Inorganic antiseptic mainly has lower TiO2, ZnO, zeolite, apatite, the metal such as porous material and silver, copper, zinc such as phosphoric acid mistake and
Its ionic compound；Organic antibacterial agent mainly includes machine acid, ester, alcohol, aldehydes matter；Biological antibiosis agent is primarily referred to as driven plant
The antiseptic of extract in object and fermentable production, such as berberine, tetracycline macromolecular structure compound and big
The plant of garlic etc.
Due to organic anti-biotic material there is antibiotic property weaker, heat resistance, less stable, itself catabolite and volatilization
Thing may be harmful, is also easy to produce drug resistance, the shortcomings of easily causing secondary pollution and be unsuitable for high temperature process, limits it
Use, and gradually substituted by the good mineral-type anti-biotic material of photostability, persistence, security.
In recent years, the catalysis material with titanium dioxide as representative has obtained extensive research, due to TiO2Photocatalysis resists
Persistently, making excitaton source using the ultraviolet light contained in sunshine, fluorescent lamp can have antimicrobial effect to bacterium material effects effect, and
With photocatalytic effects such as purify air, sewage disposal, automatically cleanings, the prospect of being widely applied is illustrated in terms of environmental protection, into
For the inorganic antibacterial scavenging material valency of a new generation.
TiO2Light-catalyzed reaction is the reaction that light evokes, although as long as there is faint ultraviolet light, such as sunshine, fluorescence
Contained ultraviolet light can evoke reaction in lamp.But in unglazed irradiation, light-catalyzed reaction, TiO will not occur2Also just do not have
Anti-microbial property.
Therefore, by nano-TiO2Combine with organic antibacterial agent, then can both ensure still have antibacterial to imitate in unglazed irradiation
Really, the defects such as organic antibacterial agent heat resistance, less stable can be avoided again.
The content of the invention
For the deficiency of existing antiseptic, it is whole that the technical problem to be solved is to provide a kind of bafta antibacterial
The preparation method of reason agent, especially with nano titanium oxide, pyridine antibacterial monomer as main antimicrobial moiety, using polymerization
Bafta antibacterial finishing agent is prepared, pyridine antibacterial monomer is grafted on nano zine oxide, be limited in pyridine antibacterial monomer
In matrix, the defect that pyridines antiseptic exists as organic antibacterial agent was both overcome, the antimicrobial long-acting of antiseptic had been improved again
And validity.
For achieving the above object, the technical solution used in the present invention is：
A kind of preparation method of bafta antibacterial finishing agent, each component is comprised the following steps in terms of mass parts：
Step one is by 7 parts of cetyl trimethylammonium bromides, 5 parts of OP-10,22 parts of pyridine antibacterial monomer 4- vinylpyridines
Pyridine nitrate, 6 parts of 3- vinyl aniline, 5 parts of hexafluorobutyl acrylates, 8 parts of surface-modified nano titanium dioxide and 347 parts go from
Sub- water is added in emulsifying kettle, 30min is stirred under rotating speed 600r/min, into emulsion；0.3 part of potassium peroxydisulfate and 30 parts are gone from water
It is dissolved into initiator solution；
Step 2 adds the emulsion of 1/3 debulking step one in reactor, is warming up to 68 DEG C, adds drawing for 1/3 volume
Send out the agent aqueous solution, insulation reaction 30min；
Step 3 is added dropwise remaining emulsion and remaining initiator solution, completion of dropping, by temperature of reaction kettle in 2 hours
80 DEG C are risen to, 0.5h is incubated；
Temperature of reaction kettle is down to 45～50 DEG C by step 4, adds the solution of 0.2 part of silver nitrate and 20 parts of deionized waters,
After stirring, the solution of 0.2 part of sodium borohydride and 20 parts of deionized waters is rapidly added, carries out reduction reaction；200 mesh sieves are crossed,
Obtain bafta antibacterial finishing agent.
The preparation method of the surface-modified nano titanium dioxide is：
8 parts of nano-titania particles are added in 30 parts of ethanol and are dissolved, ultrasonic disperse 15 minutes adds 20 parts of ethanol
With the mixed liquor of 1.2 parts of silane coupler γ-(methacryloxypropyl) propyl trimethoxy silicane, 70 DEG C are heated to, constant temperature is anti-
Answer 3 hours, be dried after scrubbed, filtration, grind to form powder shaped modified nano-titanium dioxide.
Nano-TiO2Because it has the performances such as good uvioresistant, antibacterial and deodouring, catalytic degradation, and TiO2It is nontoxic, have
Preferable chemical stability and cheap and easy to get, therefore it is widely used in building coating, function textile, sun care preparations, sewage
The fields such as process.However, nano-TiO2Specific grain surface product is big, surface energy is high, by Van der Waals force between particle in liquid phase medium
Effect and reunite；Additionally, nano-TiO2With Superhydrophilic, it is difficult dispersion in organic phase solution, and disperses
Stability is poor, and this becomes nano-TiO2Problem demanding prompt solution during use.Raising nano-powder is in organic phase medium
The common method of dispersiveness is organic surface modifying method, mainly there is polymer encapsulation, surfactant method and modification by coupling etc.,
Wherein, the method being modified to powder using coupling agent is more universal.Coupling agent is a kind of by hydrophilic polar group and parent
The non-polar group Amphi-pathic compound dimerous of oil, the hydrophilic radical in its molecule is anti-with the hydroxyl of nano powder surface
Should, make nano grain surface hydrophily be transformed into lipophile, so as to reach the compatibility for improving nano-powder and organic phase liquid.
The method of nano titanium oxide ion surface grafting of the present invention using pyridine antibacterial monomer after modification, makes pyridine
Limit in the base, promote uniform, the stable dispersion of nano titanium oxide, and Nano Silver is generated in strand, overcome
Nano titanium oxide dark place can not play that antibiotic property and pyridine derivate antiseptic security are poor, can produce microorganism drug resistance,
The shortcomings of poor chemical stability, poor heat resistance, realize the safe, lasting of antiseptic, high efficiency.
Specific implementation method：
Following embodiment, is merely illustrative of, and is not only, so, all within the scope of the present invention or do with
The similar change of the present invention is both contained within the present invention.
