Description
Technical field
The present invention relates to automobile packaging composite film technical field more particularly to a kind of vehicle complete vehicle protective film and its preparation sides
Method.
Background technique
With the improvement of living standards, automobile more and more enters average family, market car ownership is higher and higher.
Automobile, into shipping channels, is sent to all parts of the country after manufacturing enterprise is completed.During transportation, body of a motor car light
According to and dust, stone, the grains of sand impact, car surface vehicle paint will receive damage, causes unnecessary trouble on sales section, this
It just needs to provide automobile during transportation a kind of surface protection, bodywork surface is prevented to be damaged.Between this, vehicle complete vehicle
Shipment protective film comes into being, and solves the problems, such as to come to harm during Automobile Transportation, while can give Automobile again
Paint provides protection, prevent vehicle paint from being irradiated by the ultraviolet light in sunlight and generate weather stain etc..In a way, automobile goes out
Goods protective film not only provides vehicle body protection during Automobile Transportation, also uses as automobile painting surface protective film.
Automobile painting surface protective film is otherwise known as vehicle body stealth protective clothing, is a kind of high performance membrane, frivolous penetrating, has superpower
Toughness can effectively prevent the impact of scratch, handstone and the grains of sand, moreover it is possible to which perfection is attached to surface of vehicle paint, makes vehicle paint and air
Isolation, effectively acid rain preventing, anti-oxidation, resistance scratch, and persistently protect automobile finish.
On domestic and international market, the automobile shipment protective film scheme that many producers provide is mainly that the self-adhesion of multilayer PE co-extrusion is protected
Cuticula or the PE protective film of PE basement membrane and acrylic glue combination will receive heat, oxygen, ultraviolet light etc. during Automobile Transportation
Effect, adhesive layer can substantially climb to the adhesion strength of body of a motor car.When needing to peel protective film from vehicle body, gluing
Agent can more or less remain in bodywork surface, cause unnecessary pollution, this brings inconvenience to bodywork surface cleaning.So this
Kind PE protective film can not also be used as automobile painting surface protective film；Moreover, this vehicle paint protective film mainly protects lacquer painting
Shield, does not protect Automobile Transportation process；And as market mainstream automobile painting surface protective film, product material is a kind of polyurethane
Film contains anti-UV polymer, yellowing-resistant, and toughness with super strength, does not turn yellow, impact resistant at wearability, can make automobile coating after dress patch
Face and air exclusion, acid rain preventing, it is anti-oxidation, resist and scratch, persistently protect the effect of the lacquer painting of car, but it is in pad pasting process
In, using wet film coating, steam and bubble, more inconvenience in operation slowly then are removed with soft scraper.

Comparative example 4
This comparative example provides a kind of vehicle complete vehicle shipment protective film, including the UV type polyurethane adhesive coating to fit
(raw material is the solvent-free UV type polyurethane pressure sensitive adhesive of Sartomer Guangzhou Chemical Co., Ltd. production, system viscosity 350-
1500cps) and UV type TPU adhesive coating；
In parts by weight, the raw material composition of the UV type TPU adhesive coating includes:
Polyfunctional group oligomer (aromatic urethane acrylate 6121F-80, the manufacture of double bond Chemical Co., Ltd.) 50g,
Polyfunctional monomer (pentaerythritol triacrylate PETA, the manufacture of double bond Chemical Co., Ltd.) 40g, levelling agent (BYK3500,
The manufacture of Bi Ke company) 1g, wax assistant (polyethylene wax slurry) 2g, fluorine auxiliary agent (KF1203, Co., Ltd., SHIN-ETSU HANTOTAI manufacture) 2.5g and
Photoinitiator (photoinitiator 184, the manufacture of Tianjin proud son of heaven Chemical Co., Ltd.) 4.5g.
The vehicle complete vehicle shipment protective film of the present embodiment is such use or preparation:
Polyfunctional group oligomer and polyfunctional monomer are put into 200mL shading bucket, are stirred with high speed disperser
Uniformly, then in order levelling agent, wax assistant, fluorine auxiliary agent and photoinitiator is added, with the revolving speed high-speed stirring of 1200rpm after having added
After mixing 60min, stands 60min or more and defoamed naturally to get the raw mixture of UV type TPU adhesive coating is arrived；
Solvent-free UV type polyurethane pressure sensitive adhesive is sprayed on automobile finish using sprayer, forms uniform 50 μ m thick
UV pressure-sensitive adhesive layer, then with UV (intensity 200mw/cm2, energy 450mJ/cm2) be irradiated 1 minute, obtain 50 ± 2 μ
The UV type polyurethane adhesive coating of m, as lacquer painting protective film adhesive layer；
Then the raw material of sprayer spraying UV type TPU adhesive coating is used on the surface of UV type polyurethane adhesive coating
Mixture forms the UV type TPU glue-line of uniform 15 μ m thick, then with UV (intensity 80mw/cm2, energy 150mJ/
cm2) 30 seconds film forming are irradiated, 15 ± 2 μm of UV type TPU adhesive coating is obtained, is arrived as lacquer painting protection membrane coat
Vehicle complete vehicle shipment protective film.
The performance of the obtained vehicle complete vehicle shipment protective film of embodiment 1-5, comparative example 1-4 is tested, result is such as
Shown in the following table 1:
Table 1
Note: 1, resilient property, it is shorter to restore the state for time such as original shape, illustrates that self-reparing capability is higher；
2, water contact angle expression value is bigger, and antifouling capacity is better, and self-cleaning ability is also stronger；
3, YI value and b* value represent coating xanthochromia degree, such as the time in the case where sunlight irradiates is longer, are worth bigger, explanation
Xanthochromia is more severe；
4, film property is taken off, test condition is that the sun is exposed to the sun 60d, is tested after test sample plate is then put into room temperature preservation 2h；
5, Anti-Blocking test method: coat side doubling is mutually slided, if clog-free sense and than more smooth,
The adhesion inhibiting properties of coating are preferable.
Therefore vehicle complete vehicle shipment protective film of the invention sprays work using two-period form without being coated on substrate
UV type polyurethane pressure sensitive adhesive is directly sprayed to body of a motor car surface first, through UV lamp radiation curing at pressure-sensitive adhesive film, then by skill
UV type TPU glue is sprayed into UV pressure-sensitive adhesive film coating surface again, then is radiated through UV lamp into functional coating, it can be various to vehicle body
Curved surface and dead angle perfection fitting, it is moderate to lacquer painting adhesion strength, transport afterwards and with during vehicle without reflex action；The nothing of use
Solvent UV type polyurethane pressure-sensitive adhesive coating, the coating after UV lamp radiation curing film forming, assign the good adhesion strength of coating and at
Mould, ageing-resistant performance is excellent, guarantees taking off not tearable in membrane process later, is not easy residue glue；The functional TPU used is applied
Layer has the ductility and toughness of appropriateness, is not easy to shrink, non yellowing, and full light transmission rate is higher, at the same coating have it is special at
Film property and self-healing properties, when coating is by slight scratch, the short time will slowly self-regeneration, restoring coating, self is perfect
State, while coating contains efficient light stabilizer and fluoride auxiliary agent, and coating protection film surface can be made to contact with high water
There is certain anti-pollution function at angle, while coating protective film has excellent in an outdoor environment ageing-resistant performance and color inhibition
Property, coating protects film properties to stablize.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
