Abstract
The invention relates to a super weather resistant low-temperature curing powder coating for glass reinforced plastic, which is mainly applicable to surface spraying of glass reinforced plastic and a finished product thereof, and belongs to the field of functional powder coating. Formula of the powder coating mainly consists of the following raw materials polyester resin, a curing agent, an adhesion promoter, a curing reaction accelerant, pigment and filler, and other auxiliaries. The powder coating disclosed by the invention can be cured into a film in short time at relatively low temperature, and the cured coating is excellent is weather resistance and adhesion. The powder coating disclosed by the invention not only solves the problems of a normal powder coating which is poor in adhesion on the glass reinforced plastic and the finished product thereof, but also reduces temperature and time of curing the powder coating into the film, which is favorable for reducing energy consumption and saving energy; the powder coating also avoids problems of the glass reinforced plastic and the finished product which are poor in use performance and service life due to excessive roasting temperature.
Description
Technical field
The present invention relates to super weather-proof low temperature cured powder coating for a kind of glass reinforced plastic, belong to functional powder paint field.
Background technology
Powder coating is a kind of 100% solid part of containing, and produces solidification process and does not contain the novel environment friendly coating material of liquid solvent and organic volatile thinner.Because it has the advantages such as environment friendly and pollution-free, energy-efficient, simple process, coating be sturdy and durable, all over the world, every field is just being widely used for it, and now just with annual tens percent speed increment.Powder coating has occupied very important status in coating industry.Solid powder paint is because the outstanding feature of environmental protection more and more receives people's concern.
Glass reinforced plastic is a kind of matrix material, and the subject range of its performance is very extensive.Because having the advantages such as high-strength light, corrosion-resistant, electrical property thermal characteristics is good, designability is good, it by people, is more and more paid close attention to.But because glass steel material is different from traditional metal material, ordinary powder paint spay-coating exists sticking power poor after solidifying, surface effect is bad, the disadvantages such as outdoor weather resistance is poor, and ordinary powder coating is generally at 200 ℃ of melting and solidifications, excessive temperature baking has affected use properties and the work-ing life of glass reinforced plastic, and the spraying that is not suitable for glass reinforced plastic and goods thereof is used.
People are more to the research of low-temperature curing or super weather-resistant powder paint in recent years, but the almost not research to glass reinforced plastic and goods proprietary powder coatings thereof.
Chinese patent CN103122205A discloses a kind of low-temperature curing super-weathering resistance powder coating, but the disclosed powder coating of this patent can not solve glass reinforced plastic and the poor technical problem of postadhesion power is solidified in goods spraying.
Chinese patent CN102250529A discloses a kind of ultralow-temperature cured epoxy powder coating and preparation method thereof, this patent formulation is to take epoxy resin as binder resin, because being subject to UV-irradiation, easily decomposes epoxy resin, so this patented powder coating can, for outdoor, not have super weather-proof performance.Therefore need the powder coating that a kind of applicable glass reinforced plastic of exploitation and goods thereof are used badly.Summary of the invention
The object of this invention is to provide super weather-proof low temperature cured powder coating for a kind of glass reinforced plastic, this powder coating can be at lesser temps, film-forming in the short period, and the coating after solidifying has excellent weathering resistance, sticking power preferably.
Glass reinforced plastic of the present invention is to using the super weather resistant terminal carboxyl polyester resin of high acid value as base-material with super weather-proof low temperature cured powder coating, beta-hydroxy alkylamide is solidifying agent, add again adhesion promoter and curing reaction promotor, to adjust its sticking power and solidification value and time.
Described glass reinforced plastic is made by the raw material of following mass percent with super weather-proof low temperature cured powder coating:
Wherein:
Described vibrin is 2441 vibrin preferably, Zhan Xin resin (Shanghai) Co., Ltd.;
The preferred Primid XL-552 of described solidifying agent, Hangzhou Rui Ke Chemical Co., Ltd.;
Described adhesion promoter is any auxiliary agent that can improve powder coating sticking power, preferred W-9085, Suzhou Pa Tena Chemical Co., Ltd.;
Described curing reaction promotor is anyly can reduce powder coating solidification temperature of the present invention and the reaction promotor of set time, preferred DBU/6674-22-2, Xin Dian chemical material (Shanghai) Co., Ltd.;
The preferred Hensic H-136 of described flow agent organic silicon modified by polyether flow agent, Guangzhou Heng Sike trade Co., Ltd; The preferred 0.5-3% of its mass percent.
The preferred sand streak agent 812 of described sand streak agent, Hubei Lai Si company; The preferred 1.2-3% of its mass percent.
The preferred German Bi Ke CERAFLOUR961 air release agent of described air release agent;
Described oxidation inhibitor preferably 1010, chemical name four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester; The preferred 0.7-3% of its mass percent.Described color stuffing is the color stuffing that ordinary powder coating is used, and according to formulating of recipe, determines its concrete consumption.
Powder coating of the present invention makes according to conventional preparation method.By specific client requirement, determine powder coating formula → take raw material → machine batch mixing → coextrusion in batch mixing pot → compressing tablet material → pulverizings → grinding → mistake screen sizing → powder coating product detection packing → finished product by formula.
Powder coating of the present invention is sprayed on glass reinforced plastic and product surface thereof, and through 150-160 ℃, it is better that the melting and solidification of 8-12min can obtain sticking power, and what outdoor weatherability was good films.And the consumption of flow agent and sand streak agent is adjusted the surface effect of powder coating in can filling a prescription by adjustment, can prepare the super weather-proof low temperature cured powder coating for glass reinforced plastic of plane and sand streak different-effect.
Beneficial effect of the present invention is as follows:
Powder coating of the present invention can be at lesser temps, film-forming in the short period, and the coating after solidifying has excellent weathering resistance, sticking power preferably.The present invention had both solved ordinary powder coating to glass reinforced plastic and the bad problem of goods sticking power thereof, reduced again the temperature and time of powder coating solidification film forming, be conducive to reduce energy consumption, save the energy, also avoided glass reinforced plastic and goods thereof simultaneously because the problem declining in the too high use properties causing of storing temperature and work-ing life.
