Description
Technical field
The present invention relates to automotive powder coating.
Background technology
At present, along with the develop rapidly of global industry, the environmental problem caused also becomes increasingly conspicuous.How to carry out the important topic that environmental protection work has become urgently people's research.Some western countries development research that Environmental awareness is strong goes out to have the car paint of low volatile organic, and puts into production in a large number and use.Along with the development of automobile industry, in order to beautify the appearance of film of automobile, alleviating the environmental pollution that it causes, improving vehicle spray painting technology and seeming particularly important.
For automotive powder coating, the sticking power of powder is extremely important, if the sticking power of powder coating is little, then the paint film sprayed easily drops off, and affects the life-span.
In the summer of sweltering heat, as long as we can find car to be parked in a bit of time under the sun, then car is interior with regard to heat very, and these heats are mainly through vehicle body transmission, and therefore, the coating studying a kind of heat-proof quality good necessitates.
Summary of the invention
In order to improve the sticking power of powder coating, improving the heat-proof quality of powder coating, the invention provides the reflectivity automotive powder coating that a kind of sticking power is good.
For achieving the above object, the reflectivity automotive powder coating that sticking power is good, count by weight, be made up of the polyamide resin of 50-60 part, 10-20 part epoxy resin, 10-20 part modified rosin resin, 2-3 part magnesium carbide, 10-15 part fluorine carbon, 6-8 part nano-hollow glass fibre, 15-20 part titanium dioxide, 3-6 part iron oxide red, 5-10 part organosilicon, 2-3 part solidifying agent 1-3 part stablizer and 2-4 part flow agent.
Further, described solidifying agent is hydroxyalkyl amide.
Further, described stablizer is Zinic stearas.
Further, described flow agent selects the product of Dow Corning Corporation, and model is 5T.
The invention has the beneficial effects as follows: add organosilicon and can reduce epoxy resin internal stress, the performances such as epoxy resin toughness, high thermal resistance can be improved again.In the process forming powder coating, the fusing point of polyamide resin and modified rosin resin is low, under the effect of organosilicon and epoxy resin, make the particle of powder coating close to spherical, like this, just can improve the sticking power of paint film, paint film is not easy to drop, long service life.Owing to adding magnesium carbide, nano-hollow glass fibre and titanium dioxide, therefore, infrared reflectance can reach more than 90%, and heat insulation rate can to 98%.Owing to adding fluorine carbon, modified rosin resin and nano-hollow glass fibre, make the thickness of paint film little, consumption paint amount is little, and pore is few, weathering resistance and water-tolerant.
