Abstract
The invention provides an antifog bactericide for an automobile window, which has a long-time effective antifog function on the automobile window and a rearview mirror and a bactericidal function of purifying air in an automobile to fulfill the aim of safely and healthily driving. The antifog bactericide is prepared by uniformly mixing absolute ethanol, propylene glycol, isopropanol, an alkylolamide nonionic surfactant of which the oleophylic end contains 11 to 14 carbon atoms, deionized water, polyvinylpyrrolidone, and a water soluble nanometer titanium dioxide in a certain ratio according to a certain order. The antifog bactericide is filled in a spray bottle and is sprayed. The antifog bactericide is easy to prepare, economical and practical, and convenient to use.
Description
Technical field
The present invention relates to a kind of Antifog bactericide for automobile window, belong to vehicle window antifogging agent and sterilant preparing technical field.
Background technology
Windshield and rearview mirror all can produce mist vapour and affect sight line in winter or the rainy day of cold, cause serious traffic safety hidden danger, in car, water vapor is met cold meeting and condense into many droplets on sheet glass, these globules are shrunk to semisphere or spherical under capillary effect, make light scatter, driven to cause very important driving dangerous to the driver.Because automobile usually travels under the state of sealing, the atmosphere draught-free in car except being easy to haze, also can cause spreading of bacterium in car, causes the infection of some disease.Therefore, solve vehicle window and rearview mirror haze and car in the purifying problem of air, driving is most important for ensuring safety.
The present invention is intended to design a kind of safe, economic, effective, green existing anti-fog function, the multi-functional antifogging agent of sterilization functions is arranged again, to improve the security of driving.
At present, the antifog method of vehicle window mainly contains following several both at home and abroad:
(1) the bad glass of exploitation thermal conduction or blow hot blast at the glass inner face, purpose is that the temperature of glass inner face is dropped to below dew point;
(2) reduce indoor humidity with dehydrating unit;
(3) a kind of anti-fog thin film of coating on glass;
(4) on glassly smear one deck antifogging agent, even water vapour in the glass surface dewfall, does not also allow it exist with drops, but make it be transformed into the high moisture film of transparency.
First, second kind method is install an air-conditioner in the medium and high classes automobile and use antifog property windshield glass preferably, but to most of popular automobiles, as truck, motorbus, motor bus etc., this method is too expensive.The third method must be used in glass manufacturing process, its complex process, and to finished glass processing inconvenience.The 4th kind of method as the antifogging agent of glass, is to form coating by lyophobic dusts such as metallic soap, silicon, zirconium compounds, alkyl pyridine halogenide, urea.As general method, by the top coat that lyophobic dust forms, from anchorage and persistence, fail to obtain satisfied effect.
And it is very few for the research of car inner air-cleaning sterilization both at home and abroad, although the patent of current existing many vehicle window antifogging agents, as anti-fog agent for wind-screen of automobile CN101108960, anti-fog agent for wind-screen of automobile CN1632037, agent for dirt-removing and antifogging CN1418787 etc., but the vehicle window antifogging agent that has good sterilizing function concurrently is also unprecedented.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of comparatively desirable multi-functional antifogging agent is provided.
A kind of Antifog bactericide for automobile window of the present invention is characterized in that having following moiety and weight percent thereof:
Dehydrated alcohol 20～25%; ,
Propylene glycol 12～15%,
Virahol 12～15%,
Alkylol amide 7～9%,
Polyvinylpyrrolidone 0.3～0.5%,
Deionized water 45～48%;
Water soluble nano titanium dioxide is counted 10mg/L with bulking value concentration; Be to contain 10mg titanium dioxide in every liter of solution;
Described alkylol amide is the nonionogenic tenside that a kind of hydrophobic end contains 11-14 C; Described dehydrated alcohol, propylene glycol, Virahol are solvent, and described polyvinylpyrrolidone is dispersion agent.
The preparation method of a kind of Antifog bactericide for automobile window of the present invention is characterized in that having following preparation process and step:
A. by said components formula weigh batching;
B. add successively sequentially dehydrated alcohol, propylene glycol, Virahol, deionized water, alkylol amide; Add polyvinylpyrrolidone, water soluble nano titanium dioxide after stirring; Adopt sonic oscillation to make Solution Dispersion even;
C. pack in opaque spray bottle.
The invention has the advantages that:
(1) preparation technology is simple, raw materials cost economy;
(2) effectively, antifog lastingly, stable performance;
(3) absorb the ultraviolet catalytic sterilization, purifying in-vehicle air, green non-poisonous.
Embodiment
After now specific embodiments of the invention being described in.
Embodiment 1 and embodiment 2 component formula such as following table 1:
The component formula of table 1 embodiment 1 and embodiment 2
Data in above form are all to be obtained by round.
Preparation method in the present embodiment: at first by certain quality percentage composition feeding, then add successively dehydrated alcohol, propylene glycol, Virahol, deionized water, alkylol amide, add polyvinylpyrrolidone, water soluble nano titanium dioxide after stirring, method by sonic oscillation is evenly distributed solution, can use in the opaque spray bottle of packing at last.
During use, on vehicle window, then using cloth to wipe with to wipe away evenly gets final product on a small quantity in ejection from spray bottle.
In January, 2011, done antifog and bactericidal assay to this invention:
Antifog test: spraying antifogging agent of the present invention on the vehicle window of the left side of dickey seats, the right side does not spray, 20 days afterwards discovery do not spray on the vehicle window of antifogging agent of the present invention and hazed obviously, and sprayed on the vehicle window of antifogging agent without hazing phenomenon, and sight line can be not influenced when seeing through this window and outwards seeing.
Bactericidal assay: take 9 gram nutrient agar mediums and be dissolved in 250 milliliters of 50 ℃ of distilled water and be mixed with substratum; Get 10 milliliters of sewage conducts and contain the bacterium inoculation liquid, and dilute 1000 times with sterilized water.The instruments such as culture dish, transfer pipet are put into 120 ℃ of sterilizations of electric-heating steam pressure sterilizer 15 minutes.
Under aseptic condition, inject respectively 20 milliliters of substratum in four culture dish, after substratum is cooling, add respectively 1 milliliter to contain the bacterium inoculation liquid in four culture dish, then add respectively 1 milliliter of self-control Antifog bactericide of spending 2 hours through solar radiation in two culture dish wherein; And do not add Antifog bactericide in two other culture dish; Make blank simultaneous test; Use spreading rod respectively that the liquid spreading on substratum in four culture dish is even.Use covers above-mentioned four culture dish respectively through the large size culture dish of disinfecting action, after congealed solid total condensation wherein, culture dish is inverted in the incubator of 38 degrees centigrade.After 48 hours, take out culture dish and observe to find: the colony number that was coated with on two congealed soliies of Antifog bactericide of the present invention is respectively 2 and 1, and the colony number that was not coated with on two congealed soliies of the Antifog bactericide of invention not is respectively 19 and 21.
