Description
Technical field
The invention belongs to coating material production field is and in particular to a kind of water soluble paint and its application.
Background technology
The environment that automotive oil tank uses is general all more severe, along with location structure itself is in the bottom of car,
Expose in atmosphere throughout the year；And the year limit for length using, requires higher to corrosion resistance.By carrying out at spraying to tank surface
Reason, can strengthen its antiseptic property, thus increasing service life.Spraying technology traditional at present is to carry out application, base with solvent-borne type
Originally the performance requirements such as automobile is anti-corrosion and weather-proof can be met, spraying coating process Technical comparing is good ripe.But solvent based coating contains in a large number
Harmful poisonous solvent, and inflammable and explosive, environment is caused larger because of a large amount of discharges of organic solvent in work progress
Pollution, carries out that oil paint construction is larger to body harm ratio for a long time, and taste is heavier, and does not meet national environmental protection application
Demand for development.
Going deep into prevention and control of air pollution, the pollution control of coating industry is also quietly launching, currently hydrotropism
Coating, powdery paints, the direction of high solid coating application are developed, wherein more rapid with water paint development.
Water soluble paint has the advantages that asepsis environment-protecting, odorlessness, low volatilization, does not fire not quick-fried high security.But at present,
Water paint is relatively immature due to technology, ensures without the construction technology technical conditions that good formula is become reconciled, automobile
Corrosion resisting property after fuel tank spraying does not just reach requirement, or coating quality is unstable, can not meet fuel tank quality requirement.

Should be noted following main points in spraying operation：
(1), spray gun can make up and down, move left and right, spray angle with vertical with working surface as principle, and according to working face
The complexity conversion angle of gun and speed of service, have dead angle position, should by spray gun shift near spraying point carry out suitable interrupted
Spraying, makes every effort to reach uniform coating thickness.When being sprayed onto working face two ends, button spray gun trigger hand will rapidly pine once,
Coating cloud is made to reduce, because the two ends of working face, spraying that often will be above twice, is the place being easiest to cause sagging.
(2) one coating to be descended to push down the 1/3 or 1/4 of one coating when, spraying, it is to avoid drain spray phenomenon occurs.?
Before the coating of spraying is done, need once to have sprayed in order.The effect that fills spray is undesirable.
(3), the order of spraying is：Difficult at first and quite easy afterwards, from inside outwards.Lower after first eminence, large area after first small area.So
The coating cloud that would not spray after causing is splashed on the paint film having sprayed, and destroys the paint film having sprayed.
