Abstract
The invention relates to a preparation method of a long-acting wiping-resistant window glass anti-fogging agent, and belongs to the field of anti-fogging agent preparation.The method comprises the steps that aluminum sol is prepared, castor oil is prepared through the squeezing process, polytetrafluoroethylene, polyvinyl alcohol and magnesium stearate are used for assisting, all the materials are compounded in a high temperature reaction kettle, and the long-acting wiping-resistant window glass anti-fogging agent is obtained.According to the prepared anti-fogging agent, the castor oil and the aluminum sol serve as the base materials, after the base materials are coated, a firm metal-oxide oily film can be formed on the glass surface to keep the glass surface wet, and the problem that a traditional anti-fogging agent is not resistant to wiping is solved; then nano-titanium dioxide and polyurethane are added, so that the anti-fogging agent has better film-forming property; nano-titanium dioxide can prevent ultraviolet and decrease the contact angle of the film surface of the anti-fogging agent simultaneously, water in air is diffused after making contact with the film surface to form a water film, scattering is not caused, the fogging phenomenon is prevented, the defects that the traditional anti-fogging agent is poor in film-forming property and short in anti-fogging time are overcome, and an excellent anti-fogging effect is achieved.
Description
Technical field
The preparation method that the present invention relates to a kind of long-acting glass for vehicle window of resistance to wiping antifoggant, belongs to antifoggant preparation field.
Background technology
When using glass and transparent plastic, often there is certain temperature difference in its both sides spaced apart from each other, and the steam in air at its surface aggregation mist formation, can adhere to the globule (condensation), even all right frosting as too low in side temperature.It is mist or frost all can significantly reduce the light transmittance of transparent material, affect sight line, brings inconvenience, even cause great loss.The fog let us " looking at flowers in a fog " of such as lens surface, but this inconvenience still can be restrained oneself, and the atomization of glass for vehicle window is the hidden danger of a large amount of vehicle accident.Time particularly in rainy season, if vehicle window is not wiped, driver is basic just cannot normal driving, it is necessary to stops and with rag, fog is wiped clean, could continue driving.Atomizating phenomenon also creates a large amount of wastes of resource, such as the corrosion etc. of steel.So preventing atomization is one and production, closely-related problem of living.A small amount of anti-fouling agent just can reach to make the purpose of surface modification, protection, modification base material.If fogging problem can be solved with antifoggant, huge economic benefit will be brought.
Antifoggant is a kind of low-molecular-weight dispersant containing hydrophilic group, by the molecular composition determining molecular size range, it is coated on transparent substance surface and can form a coating, the hydrone in hydrophilic group energy absorbed air in coating, at transparent substance moistened surface, diffuse to form moisture film (rather than globule), make the light passing through object will not produce scattering, it is to avoid the generation of fogging phenomenon.Main component is exactly surfactant, such as the ester of xylitol, sorbitol palmitate, lauric acid or animi resin monoglyceride etc..He is a kind of instant antifog preparation, and the antifog persistent period is shorter, poor adhesive force, general only several days or tens days, by wiping or be flush with water rear defence fog effect and disappear at once, uses so cannot function as long-acting antifog preparation.
Summary of the invention
The technical problem that present invention mainly solves: the component for antifoggant common at present is all small-molecule substance, antifog film truly can not be generated, weak to wiping, not solvent resistant, antifoggant runs off along with the volatilization of moisture, antifog timeliness is made to shorten, it is impossible to play the defect of anti-fog effect for a long time, it is provided that the preparation method of a kind of long-acting glass for vehicle window of resistance to wiping antifoggant.First the method prepares Alumina gel, prepares Oleum Ricini again through squeezing, is aided with politef, polyvinyl alcohol and magnesium stearate, namely obtains the long-acting glass for vehicle window of resistance to wiping antifoggant after composite in pyroreaction still.With Oleum Ricini and Alumina gel for base material in the antifoggant that the present invention prepares, one layer of firmly metal-oxide oiliness film can be formed at glass surface after coating, keep glass surface moistening, solve the tradition antifoggant problem weak to wiping.Antifoggant is made to have better film property again through interpolation nano titanium oxide and polyurethane, nano titanium oxide reduces the contact angle on antifoggant film surface while UV resistance, the water in air is made to diffuse to form moisture film after being in contact with it, do not produce scattering, prevent fogging phenomenon from occurring, compensate for again tradition antifoggant film property poor, the deficiency that antifog timeliness is short, there is splendid anti-fog effect.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
(1) weigh 10～15g aluminum isopropylate. and be dissolved in 100～150mL dehydrated alcohol, putting in ultrasonic disperse instrument disperses 30～40min to obtain precursor liquid with 200～300W power ultrasonic, driving addition 200～300mL concentration in liquid further along is 0.1mol/L salpeter solution and 1～2L deionized water, move into and obtain Alumina gel after 60～80 DEG C of water-baths stir hydrolysis 1～3h, standby；
(2) put into after castor bean being dried in kitchen range top cauldron and roast 30～40min at 90～100 DEG C, after roasting end, castor bean is put into and the mill groove of mill disc manually rolls 20～40min and crosses 60 mesh standard sieves, obtain castor bean powder；
(3) the castor bean powder after above-mentioned stone roller system is put in wood rice steamer, castor bean powder is covered with Folium Nelumbinis, put into and pot adds water to bottom wood rice steamer, it is heated to boiling, steaming and decocting 5～10min is till wood rice steamer surrounding steam is given vent to anger uniformly but castor bean is not yet well-done, castor bean powder after steaming and decocting is poured in the iron hoop that wheat stalk is rebasing, prepares oil expression embryo cake；
(4) prepared oil expression embryo cake is loaded in frying oil groove, clashes into oil expression with oil groove wood, through extrude fuel-displaced after collect, at oil groove mouth, the Oleum Ricini squeezed, standby；
(5) count by weight, weigh 40～60 parts of standby Alumina gel, 50～80 parts of Oleum Ricini, 5～10 parts of nano titanium oxides and 10～15 parts of polyurethane, load together in pyroreaction still, 2～5 parts of polyvinyl alcohol and 1～3 part of magnesium stearate is added after being heated to 200～250 DEG C, discharging after insulated and stirred mixing 3～5h, it is cooled to barrelling after room temperature until it, packs and obtain the long-acting glass for vehicle window of resistance to wiping antifoggant.
The concrete application process of the present invention: dip the uniform brushing of antifoggant that the present invention prepares at windshield internal layer with hairbrush, beat after opening the window and drying up, after testing, the glass for vehicle window of brushing antifoggant of the present invention can be effectively antifog more than 30 days, and do not affect the light transmission of glass for vehicle window, pH value is 7～8, to glass and user without any injury.
The invention has the beneficial effects as follows:
(1) the antifoggant good film-forming property that the present invention prepares, resistance to wiping is strong, has long-acting anti-fog effect；
(2) the antifoggant raw material that the present invention prepares is easy to get, and also has uvioresistant function, and preparation process is simple while antifog, with low cost, has broad application prospects.
