Description

A kind of paint stripper used for vehicle

Technical field

The present invention relates to paint stripper technical field, more particularly, to a kind of paint stripper used for vehicle.

Background technology

The vehicles refer to automobile, train, aircraft etc. for manned, loading means of transport.First of the vehicles Feature is fast outdoor work, movement velocity.Therefore, oxygen, sulfur dioxide, nitrogen oxygen in wind, rain, mist, air can be not only subject to The influence of compound, dust, greasy dirt, salt, birds droppings, stream etc., and due to its high-speed motion, by these external environment influences It is bigger.Second feature is strong mobility, can be worked in the various environment such as high mountain, Plain, basin, seashore, sand ground.Traffic work The surface protection coating of tool not only to protect the vehicles in various environment can not burn into do not peel off, and be also contemplated that To attractive in appearance.Therefore, it is that, mostly using baking process japanning, enamelled coating is very strong with base material adhesive force, hard the characteristics of vehicles coating Degree is high, enamelled coating surface compact light, is to be most difficult to one of coating for sloughing.

For example automobile coating is mainly made up of resin, pigment, auxiliary agent, filler, curing agent, solvent etc., increases in metal automobile paint Flash of light bronze (aluminium powder) is added, mica grain has been increased in opalescent lacquers.Automotive coatings typically have three layers：Priming paint (solvent bottom paint, electricity Swimming priming paint)；Intermediate layer priming paint (universal primer, putty, in prime, seal low priming paint), finish paint (lacquer enamel, Vinylidene Chloride porcelain Paint, alkyd resin system enamel paint, alkyd amino polyester, baking finish paint, acrylic resin baking finish paint, 2K polyurethane series finish paint). Automobile coating common resins type has：Acrylic resin, alkyd resin, polyester resin, polyurethane resin, amino resins, asphalt mixtures modified by epoxy resin Fat, hybrid resin etc..

And for example aircraft surfaces fuselage coating (being called aircraft skin coating), fuselage bottom, finish paint are generally epoxypolyamine fat bottom Paint and polyurethane type finish paint.In addition, also polyurethane primer, wherein epoxy polychlorostyrene fat priming paint have epoxy adhesive force and The pliability of resistance to abrasion and polyurethane, recoatability, compared with epoxy primer, its advantage is that bi-component pot-life is long, then is applied Good, 0.4~0.5 micron of the dried film thickness of property, can mitigate the weight of airframe.Some fuselage systems find to compare during depainting Hardly possible is de-, so making first coating with one etch priming paint on aluminium alloy, reuses the polyurethane conduct of anticorrosion fluid Base coat covers polyurethane finish paint again, and advantage is preferable resistance to soiling, and depainting performance is also relatively good during rebuilding.

Although current paint stripper or depainting cream paint stripping rate are quickly, substantially it is made up of strong acid (organic acid), Acid high, high volatility, workman applies man-hour requirement and does a full set of protection；And can cause a certain degree of to the substrate surface after depainting Damage；If using organic solvent method depainting, extending the depainting time, operating efficiency is reduced.Additionally, also right after depainting Base material carries out rust cleaning could again refresh paint, and current paint stripper does not have rust removing function.

The content of the invention

In view of the above-mentioned problems existing in the prior art, this application provides a kind of paint stripper used for vehicle.The present invention is de- Paint agent is used primarily in the shell of the vehicles such as automobile, high ferro train, aircraft, shell of the paint stripper of the present invention for the vehicles The characteristics of coating adhesion is strong, hardness is high, top layer is fine and close smooth R ＆ D design, with paint removal efficiency it is high, do not damage base material, to people Body is harmless, environmental protection the advantages of.

Test case：

Contrast paint stripper 1：The GY-713 steel paint strippers of the farsighted metal-impregnated wood material Co., Ltd of Dongguan City.This is a kind of Paint stripper is brushed, the products characteristics marked in the product packaging have：Paint removing effect is fast without hindering material, saving working hour etc..It is short several Minute can just come off the organic varnish of all metal surfaces, and polyester acrylic acid, amino ethene, organosilicon, poly- propylhomoserin, plastic-spraying etc. are set The paint shaped that fat is newly prepared is adapted to.It is using application method：This product brush is stained with the surface for needing paint removal with hairbrush, and 3~5 minutes natural Come off, then rinsed with water.Shelf-life：2 years.

Contrast paint stripper 2：The DS-070 paint strippers of the gloomy Chemical Manufacture supply of Tianjin moral.The product marked in the product packaging Feature has：Paint stripping rate is fast, to 5~80 seconds paint stripper time of metallic paint (s)；It is different according to material to plastic paint priming paint, finish paint The depainting time needs remove for 3~10 minutes, and the film removing to plastic paint is thorough, and cost is relatively low, the time is short, efficiency high；User Just, only need to be the immersion of the article of removing or by the agent brushing at removing position when using, being not required to heating can remove paint；Sealing Packaging, deposits at shady and cool, dry, it is to avoid direct sunlight；Shelf-life：2 years.

Product of the present invention：The paint stripper prepared using embodiment 3.

Contrast experiment 1：Three kinds of paint remover products are contrasted by observing, as a result as shown in table 1.

Table 1

Time	Embodiment 1	Contrast paint stripper 1	Contrast paint stripper 2
				Outward appearance	It is clear to slightly yellow liquid	It is clear to slightly yellow liquid	It is clear to slightly yellow liquid
Smell	Micro- acid	Pungent tart flavour	Pungent tart flavour
				Safeguard procedures	Common mouth mask	Acid-proof mouth mask	Acid-proof mouth mask
Corrosivity	It is manually actuated	Rubber gloves need to be worn	Rubber gloves need to be worn

Contrast experiment 2：Paint removing effect test to imitating baking finish for car.Experimental technique：Some pieces of stainless steel plates are taken, by removing The pre-cleaning operations such as rust, polishing, according to baking finish for car technique, in clean stainless steel surfaces elder generation last layer F06-8 zinc yellow azoic coupling components Aldehyde priming paint, then sprays twice Germany BASF parrot paint (L90 models) again.In outdoor placement one month after curing of coatings.By three Spray gun sprays different stainless steel plates respectively by hand to plant paint removal product, and paint removing effect is observed after spraying one time.Paint removal efficiency Computing formula is that paint film plays the soft area of Zou/paint film original area * 100%.Experimental result is as shown in table 2.

Table 2

Be can see from the data of table 2, although the advertising of contrast paint stripper 1 and 2 is all very attractive, but those are only It is directed to for common signal layer coating.As this laminated coating of automotive coatings, and the performance painted has high adsorption not Easily peelable, high intensity is not easy to crack, high glossy is difficult infiltration, and contrast paint stripper 1 and 2 does not just reach the effect of rapidly and efficiently depainting Fruit.

Contrast experiment 3：Rust-proof effect test after depainting.

After three kinds of paint removal products are by the complete depainting of stainless steel coating, rinsed with clear water, base material is then put into temperature For 40 DEG C, humidity be 80%, in the free environment of divulging information, detection substrate surface produces the time of rust staining and produces the face of rust staining Product, as a result as shown in table 3.
