Description
Technical field
The present invention relates to technical field of coatings, and in particular to a kind of high pressure resistant steam impringement metal material coating and its
Preparation method.
Background technique
In American-European and China northeast cold district, carwash often is impacted with high-temperature steam when winter is to car detailing.
High steam can not only sterilize, but also can decontaminate, and have unique thermal decomposition function, can rapidly dissolve and freeze, silt and spot it is viscous
Stickiness matter allows it to be detached from the Automotive Paint Film Properties surface attached, achievees the purpose that cleaning.But due to what is used when high-temperature steam carwash
Vapor (steam) temperature is excessively high, and pressure crosses the impacting with high pressure burden resistant to high temperatures and anti-that conference additionally increases Automotive Paint Film Properties, prolonged high temperature
High steam impact carwash will cause protection paint film and become soft and deformed or even cause local shedding.
In addition, winter in order to prevent traffic freeze and when driving vehicle occur skidding accident, the part road surface road Hui You
Political affairs administrative department arranges road surface salting to effectively prevent road surface freezing by reducing the freezing point of ice water.But these salt content are high
Ice water when being splashed on the vehicle of walking, remaining salinity is easy to the vehicle body crossed to coating protection and forms corrosion, causes outer
Corrosion in the beautiful forfeiture of table and then formation structure.
In view of the above-mentioned problems, there is coating worker to start to develop the serial 2 liquid type paint composites of acroleic acid polyurethane, endeavour
Surface is set to be hardened in the degree of cross linking raising by film coated surface, to improve the water resistance and chemical resistance of paint film.However it is this kind of
The paint film of coating has just been formed at coating initial stage and its water resistance gradually successively decreases during use, can not be fully met and is used for
The high pressure resistant steam impringement carwash demand of automobile exterior paint.
On the other hand, there is producer to meet the high temperature steam impact of paint film, after completing paint spraying, then plus brush
One layer of high temperature resistant wax liquor protects paint film.Economic cost is caused to increase and as the film thickness increase of protective layer leads to paint film
Apparent visual aesthetics is impaired, and substantially there is no promotions largely for the high temperature steam impact of film.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of high pressure resistant steam to rush
Hitting property metal material coating and preparation method thereof.
