Description

The insulating car powder coating that sticking power is good
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 heat-proof quality, the invention provides the insulating car powder coating that a kind of sticking power is good.
For achieving the above object, the insulating car powder coating that sticking power is good, count by weight, be made up of the polyamide resin of 40-50 part, 1-2 part epoxy resin, 15-25 part modified rosin resin, 20-25 part titanium dioxide, 3-6 part chrome yellow, 5-10 part organosilicon, 10-20 part glass microballon, 0.3-0.6 part dibutyl tin dilaurate, 2-3 part solidifying agent, 0.5-1 part stablizer and 2-2.5 part flow agent; Wherein, the internal diameter of glass microballon is less than 2 μm, and unit weight should be less than 160kg/m 3.
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 present invention employs glass microsphere as basic raw material, the reflective function of glass microballon is good, thus improves heat-proof quality.
Embodiment
Below in conjunction with embodiment, the present invention is further elaborated.
The insulating car powder coating that sticking power is good, count by weight, be made up of the polyamide resin of 40-50 part, 1-2 part epoxy resin, 15-25 part modified rosin resin, 20-25 part titanium dioxide, 3-6 part chrome yellow, 5-10 part organosilicon, 10-20 part glass microballon, 0.3-0.6 part dibutyl tin dilaurate, 2-3 part solidifying agent, 0.5-1 part stablizer and 2-2.5 part flow agent; Wherein, the internal diameter of glass microballon is less than 2 μm, and unit weight should be less than 160kg/m 3.Described solidifying agent is hydroxyalkyl amide.Described stablizer is Zinic stearas.Described flow agent selects the product of Dow Corning Corporation, and model is 5T.
