Abstract
The present invention relates to an antifogging liquid for glass and plastic membranes and a preparing method thereof. The antifogging liquid is prepared from 100 shares by volume of basic liquid and 2 to 5 shares by volume of additive, wherein the basic liquid is compounded from 75 to 90 wt% of alcohol, 0.01 to 0.04 wt% of metal oxysalt and deionized water as the rest; the additive is compounded from 10 to 15 wt% of fatty alcohol polyoxyethylene ether sodium sulfate, 8 to 12 wt% of sulfonic acid, 3 to 6 wt% of sodium hydroxide, 0.1 to 0.8 wt% of table salt, 0.05 to 0.3 wt% of essence and deionized water as the rest. Because the metal oxysalt has low absorbability to hydrophobic substances in the air, the hydrophilicity of surfaces can be maintained for a long time, the antifogging performance is enhanced, and the antifogging persistence is obviously improved. The antifogging liquid of the present invention can prevent fog for more than 30 days. The antifogging liquid of the present invention for glass and plastic membranes is suitable for organic glass products, inorganic glass products and plastic membrane products.
Description
Technical field
The present invention relates to a kind of anti-fogging liquid, relate in particular to a kind of glass and plastics film anti-fogging liquid, simultaneously, the invention still further relates to a kind of preparation method of this anti-fogging liquid.
Background technology
The windshield glass of aircraft, automobile, common glasses lens, the glass vision panel of opticinstrument, the glass door and window of buildings, the plastics films of farm crop plastic greenhouse etc. are easy to tie mist when relative humidity is big in cold season.Promptly form tiny water droplet, will produce the diffusion effect to light like this at body surface.Transparent material surface knot mist can reduce the transparency of material, makes troubles for production and life.Can block officer's sight line at the windshield glass upper fogging of vehicle, influence the normal driving of officer, be easy to cause traffic accident vehicle.The plastics film upper fogging of farm crop plastic greenhouse can make the sunlight transmitance reduce, thereby influences the output and the quality of agricultural byproducts.At present, though the glass antidimmer kind of selling on the market is a lot, it is higher to need heating, production unit to drop into when mostly existing preparation, especially exists the shortcoming that anti-fog performance is relatively poor, persistence is low; In addition, also there is not a kind of antifogging product that is used for plastics film at present.
Summary of the invention
The object of the present invention is to provide a kind of scientific formulation, be easy to produce, easy to use, the persistent glass of effect and plastic film anti-fog agent.
The present invention also aims to provide the preparation method of a kind of this glass and plastic film anti-fog agent.
In order to achieve the above object, technical program of the present invention lies in adopting a kind of glass and plastics film anti-fogging liquid, this anti-fogging liquid is 100 by basal liquid and additive with volume ratio: the mixed of 2-5 forms, described basal liquid is made up of following raw materials in percentage by weight: alcohols 75-90%, metal oxygen-containing hydrochlorate 0.01-0.04%, surplus is a deionized water; Described additive is made up of following raw materials in percentage by weight: polyoxyethylenated alcohol sodium sulfate 10-15%, and sulfonic acid 8-12%, caustic soda 3-6%, salt 0.1-0.8%, essence 0.05-0.3%, surplus is a deionized water; Described alcohols is one or more the mixture in ethanol, propyl alcohol, Virahol, the ethylene glycol; Described metal oxygen-containing hydrochlorate is one or more the mixture in tungstate, molybdate, the zirconate.
Described metal oxygen-containing hydrochlorate is a tungstate.
Described metal oxygen-containing hydrochlorate is one or more the mixture in ammonium salt, sodium salt, the sylvite.
Described metal oxygen-containing hydrochlorate is an ammonium salt.
Described essence is common food flavour.
Simultaneously, technical program of the present invention also lies in adopting the preparation method of a kind of glass and plastics film anti-fogging liquid, prepared according to the following steps:
(1), the metal oxygen-containing hydrochlorate of aforementioned proportion and water added in the container stirs, treat that the metal oxygen-containing hydrochlorate all adds alcohols after the dissolving while stirring, continue to stir 5-10 minute, promptly get basal liquid;
(2), the polyoxyethylenated alcohol sodium sulfate of aforementioned proportion and water added in the container stir, add sulfonic acid, caustic soda, salt, essence while stirring successively, treat that solid all after the dissolving, promptly gets additive;
(3), in proportion after getting basal liquid and additive and stirring, the gained transparent liquid is glass and plastics film anti-fogging liquid.
Because used metal oxygen-containing hydrochlorate and the additive that contains tensio-active agent in prescription, additive can make the metal oxygen-containing hydrochlorate be uniformly distributed in substrate surface.The metal oxygen-containing hydrochlorate has superpower wetting ability, its wetting ability shows that contact angle with water is below 10 °, the contact angle of body surface and water is below 10 ° the time, even airborne moisture or steam dewfall, condensed water can not form tiny isolating water droplet at body surface yet, but the moisture film of formation homogeneous, mist can not tied in the surface.In addition, because the metal oxygen-containing hydrochlorate is extremely low to the adsorptivity of lyophobic dust in the air, the wetting ability that can keep the surface for a long time, thereby strengthened anti-fog performance, significantly improved antifog persistence, the antifog time of anti-fogging liquid of the present invention can be up to more than 30 days, and glass of the present invention and plastics film anti-fogging liquid are applicable to various synthetic glass, unorganic glass and plastic membrane product.The experiment proved that, glass of the present invention and plastics anti-fogging liquid have scientific formulation, be easy to produce, easy to use, effect is lasting, advantage such as of many uses, has the excellent popularization using value.
The anti-fogging liquid for glass preparation condition of glass of the present invention and plastics film anti-fogging liquid and prior art (CN01183450A) and service condition contrast are as follows:
| The name of an article | Preparation condition | Antifog persistence |
| The anti-fogging liquid of CN01183450A | Need heating | About 2 days |
| Anti-fogging liquid of the present invention | Do not need heating | More than 30 days |
Using method is: the surface that this anti-fogging liquid is sprayed at cleaning exsiccant glass or plastic membrane product with spray method, perhaps leach anti-fogging liquid of the present invention with absorbent cotton or sponge, tamponing is treated to get final product after the solvent evaporates in the surface of cleaning exsiccant glass or plastic membrane product.
