Abstract
The invention discloses a reflective car powder coating. The reflective car powder coating comprises the following components in parts by weight: 32-40 parts of phenolic resin, 3-5 parts of epoxy resin, 15-25 parts of zinc acrylate resin, 1-3 parts of magnesium carbide, 15-20 parts of fluorocarbon, 6-11 parts of hollow nanoglass fiber, 10-15 parts of titanium dioxide, 3-6 parts of carbon black, 6-12 parts of organosilicone, 2-3 parts of a curing agent, 0.6-1 part of a stabilizing agent and 2-3 parts of a leveling agent. According to the technical scheme, the powder coating has a better effect; the fineness of the powder coating is within a relatively narrow range; the toughness and the high temperature resistance of the powder coating are improved; the reflecting property of the powder coating is improved, so as to improve the heat-insulating property.
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 effect that the fineness of powder coating can reach between 10 to 80 microns is best, and its distribution range is narrower, and the effect of generation is better.
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 make the better effects if of powder coating, allowing the fineness of powder coating in narrower scope, improving toughness and the resistance to elevated temperatures of powder coating, improving the reflecting properties of coating paint film, the invention provides a kind of reflectivity automotive powder coating.
For achieving the above object, reflectivity automotive powder coating, it is characterized in that: count by weight, be made up of the resol of 32-40 part, 3-5 part epoxy resin, 15-25 part zinc acrylate resin, 1-3 part magnesium carbide, 15-20 part fluorine carbon, 6-11 part nano-hollow glass fibre, 10-15 part titanium dioxide, 3-6 part carbon black, 6-12 part organosilicon, 2-3 part solidifying agent, 0.6-1 part stablizer and 2-3 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, thus make the toughness of powder coating and resistance to elevated temperatures good; Meanwhile, resol and zinc acrylate resin have good crosslinked action, under organosilyl effect, make the powder coating fineness of formation even, and fineness are less, therefore, spray to after on base material effective.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, zinc acrylate 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.
