Abstract

The invention discloses a mildew-proof car powder coating. The mildew-proof car powder coating comprises the following components in parts by weight: 20-30 parts of phenolic resin, 3-7 parts of epoxy resin, 20-30 parts of polyurethane resin, 10-15 parts of titanium dioxide, 8-10 parts of lithopone, 3-5 parts of organosilicone, 10-15 parts of talcum powder, 0.8-2 parts of polyvinyl alcohol, 3-4 parts of a curing agent, 0.6-0.9 part of a stabilizing agent and 1-1.8 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 mildew resistance of a coating is improved.

Description

Mildew-resistant automotive powder coating
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.
Existing most of vehicle all can run in different environment, and as rainy day, greasy weather, fine day etc., therefore, the fungicidal properties of the coating outside vehicle body is extremely important.
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 fungicidal properties, the invention provides a kind of mildew-resistant automotive powder coating.
For achieving the above object, mildew-resistant automotive powder coating, count by weight, be made up of the resol of 20-30 part, 3-7 part epoxy resin, 20-30 part urethane resin, 10-15 part titanium dioxide, 8-10 part zinc sulfide white, 3-5 part organosilicon, 10-15 part talcum powder, 0.8-2 part polyvinyl alcohol, 3-4 part solidifying agent, 0.6-0.9 part stablizer and 1-1.8 part flow agent.
Further, described solidifying agent is fatty polyamide type amine.
Further, described stablizer is the large ring triazine-HALS that N-replaces.
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, thus make the toughness of powder coating and resistance to elevated temperatures good; Meanwhile, resol and urethane 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.The interaction of polyvinyl alcohol and urethane resin has good fungicidal properties.
Embodiment
Below in conjunction with embodiment, the present invention is further elaborated.
Mildew-resistant automotive powder coating, count by weight, be made up of the resol of 20-30 part, 3-7 part epoxy resin, 20-30 part urethane resin, 10-15 part titanium dioxide, 8-10 part zinc sulfide white, 3-5 part organosilicon, 10-15 part talcum powder, 0.8-2 part polyvinyl alcohol, 3-4 part solidifying agent, 0.6-0.9 part stablizer and 1-1.8 part flow agent.Described solidifying agent is fatty polyamide type amine.Described stablizer is the large ring triazine-HALS that N-replaces.Described flow agent selects dimethyl siloxane.
