Description
Technical field
The present invention relates to the car paint technical field, be specifically related to a kind of water-thinned antirust primer.
Background technology
Over 30 years, the Domestic Automotive Industry high speed development, particularly nearest 20 years, automotive industry presented the blowout formula and increases fast.National automobile ultimate production reached 1,379 ten thousand in 2009, and automobile pollution has reached 7,619 ten thousand.The great development of automotive industry has also driven the development of Painting Technology for Automobile, and simultaneously, automotive coating has also had leap progressive.
The car paint of China contains a large amount of volatile organic matter (VOC) still based on solvent-based system in the car paint of solvent-based system at present, and is very serious to the pollution of environment.Since the sixties in last century, in order to protect existent environment of people, countries in the world have been worked out the usage quantity of relevant laws and regulations with VOC in the restricting vehicle coating in succession.For example, the German clean air rules that come into force require the long-pending VOC quantity discharged of vehicle body coated surface should be less than 35 gram/m nineteen ninety-five
2, and use the solvent-based system car paint, the VOC quantity discharged will be up to 125 gram/m
2In order to reach environmental requirement, car paint hydropositiveization, high solid, powder coating direction develop, and wherein the Water-borne modification technology is one of valid approach.If car body coating is all realized Water-borne modification, then the quantity discharged of VOC can be reduced to 27 gram/m
2, reach environmental requirement fully.
Under the driving of strictness restriction VOC quantity discharged environmental requirement, European and American countries is greatly developed water-miscible paint, and makes great progress.Car use lacquer market is ripe at present, it is reported, and the existing water-based electrophoretic primer that adopts more than 90% of at present external car priming paint, the Water-borne modification technology has also been adopted in 88% middle japanning, and the use of water-based metal polychromatic finish also surpasses 65%.But car use lacquer also is not suitable for the application of motorbus etc., and this is because the coating process of motorbus is different fully with car.Because motorbus, car repair application, coating plastic parts can not bear high bake, generally all adopt oven drying at low temperature, promptly at 60～80 ℃ of oven dry or normal temperature self-drying, therefore adopt the acroleic acid polyurethane two-component coating at present usually, for example domestic bus, motor bus all adopt japanning, the supporting application of solvent-type acrylic polyurethane finish in solvent-borne type epoxy anti-rust paint, solvent-type acrylic urethane or the polyester-polyurethane, and the Water-borne modification technology still is blank.Though a small amount of employing Water-borne modification technology application public transport, big bus are abroad arranged, but because be difficult to reach the painting effect of high gloss, high clarity, therefore general at present water-based half light or mute light solid color enamel and the solvent-borne type high solid varnish Lacquer finish matched coating of adopting still belongs to semi-aqueous level in essence.Therefore, japanning and aqueous finish paint series product in the water-thinned antirust primer that the suitable public transport of development, big bus application are used, the water-based, realize the complete Water-borne modification of public transport, big bus application, to reduce the usage quantity of VOC, reduce environmental pollution, become the focus and the direction of automotive coating research, energy-saving and emission-reduction, low-carbon environment-friendly are had very important realistic meaning.
