It is added to metallic particles, to spray one layer of varnish above also after having sprayed to protect metallic particles not to be damaged, and keep light
Brightness, lacquer spraying technique are complicated.Opalescent lacquers is added to very thin mica grain on the basis of common paint, and color is more bright-colored, still
The somewhat expensive complex procedures of emerylite.
During use, vehicle body Chang Huiyu hard objects contact-impact causes vehicle paint to scratch to automobile, reduces aesthetics, example
Such as, in the process of moving, shock of the vehicle body by road blinding；In carwash, impurities in water washes away vehicle body.In addition,
Automobile is chronically exposed in various rugged environments, and vehicle body is easy aging, burn into full of bacterium, causes the reduction of vehicle paint glossiness.
Also, existing automobile coating, based on solvent type, a large amount of volatile organic compounds cause ecological environment in coating process
Serious pollution, while also great harm is brought to human health.Pursuit with people to higher quality of the life
With the raising of the ecological awareness, automobile coating needs more comprehensively to meet the complicated adverse circumstances that automobile uses and the spy for having safety and environmental protection
Point, therefore, developing, there is the environment-friendly water-based car paint of high gloss, scratch-resistant, impact resistance, durability to become automobile coating section
Grind the important topic of personnel.
Water paint is free of benzene,toluene,xylene, formaldehyde, free TDI toxic heavy metal using water as diluent, nontoxic stingless
Swash smell, it is harmless, it is free from environmental pollution, paint film is plentiful, it is sparkling and crystal-clear it is bright, flexibility is good and have it is water-fast, wear-resisting, resistance to always
Change, color inhibition, fast drying, it is easy to use the features such as.Therefore it is well suited as the research direction of new automobile paint.The prior art
In, it is more existing with water-based automobile paint, but there are some problems, as additive is easy to reunite, it is difficult to dispersion steady in a long-term
Or levelability is poor, the final apparent mass and mechanical property for influencing automobile.
