Description

The anti scuffing automotive 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.
Summary of the invention
In order to improve sticking power and the anti scuffing performance of powder coating, the invention provides the anti scuffing automotive powder coating that a kind of sticking power is good.
For achieving the above object, the anti scuffing automotive powder coating that sticking power is good, count by weight, be made up of the hydroxyl saturated polyester resin of the linear hydroxyl saturated polyester resin of 15-30 part, 3-5 part epoxy resin, 20-30 part is slight collateralization, 15-20 part modified rosin resin, 15-20 part titanium dioxide, 3-6 part permanent yellow, 5-10 part organosilicon, 2-4 part solidifying agent, 0.1-1 part stablizer and 2-5 part flow agent.
Further, described solidifying agent is fatty polyamide type amine.
Further, described stablizer is Zinic stearas.
Further, described flow agent selects dimethyl siloxane.
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 modified rosin resin is low, and 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.Due to the hydroxyl saturated polyester resin containing linear hydroxyl saturated polyester resin, epoxy resin, slight collateralization, therefore, the anti scuffing performance of this coating is good.
Embodiment
Below in conjunction with embodiment, the present invention is further elaborated.
The anti scuffing automotive powder coating that sticking power is good, count by weight, be made up of the hydroxyl saturated polyester resin of the linear hydroxyl saturated polyester resin of 15-30 part, 3-5 part epoxy resin, 20-30 part is slight collateralization, 15-20 part modified rosin resin, 15-20 part titanium dioxide, 3-6 part permanent yellow, 5-10 part organosilicon, 2-4 part solidifying agent, 0.1-1 part stablizer and 2-5 part flow agent.Described solidifying agent is fatty polyamide type amine.Described stablizer is Zinic stearas.Described flow agent selects dimethyl siloxane.
