Description
Technical field:
The present invention relates to the outdoor low brightness paint powder of particularly a kind of thermoset scratch resistance of a kind of powder coating, belong to technical field of coatings.
Background technology:
Powder coating is a kind of green coating of non-volatility organic solvent, and it has resource-saving, solvent-free, low pollution, high-level efficiency, characteristics such as application moulding, and Application Areas is extensive, is developed rapidly in countries in the world.Powder coating market about 30～40% is half light or the kind of low gloss more, outdoor low light powder applied range is mainly used in aspects such as building materials, aluminium section bar, bumper, outdoor household electrical appliances, outdoor pipe, freeway guardrail, outdoor advertising, metrical instrument shell and lamp decoration.There are multiple technologies to be used to reduce the gloss of powder coating systems.These technology comprise add paraffin, silicon-dioxide etc. and so on and system not mutually the filler of mixing reach the delustring purpose, but the amount of the filler that this method need add is big, performances such as the levelling property of coating and physical strength all reduce greatly; Another kind method is that doing of the active powder coating of differential responses mixed (as U.S.3,842,035 introduces), but this method needs a large amount of doing to mix experiment determines its prescription, and owing to be difficult to disperse evenly between two kinds of powder, the gloss of the coating that obtains like this differs greatly, and circulation ratio is bad; The third method is to use mixing cured system, as the different solidifying agent reaction (European Patent Application No. 366 of a kind of resin with two or more, 608 introduce) or two or more resin and a kind of solidifying agent effect (Japanese patent application No. 154,771/88 introduces) and various kinds of resin and multiple solidifying agent effect, the problem of this method is that the proportioning of different curing system is very big to the gloss influence, can different in addition solidifying agent uniform distribution in powder, gloss and planeness to coating all have a significant impact, and under the fabrication process condition of present powder coating, realize that almost be impossible at these 2.Therefore the circulation ratio of this method is very poor, and levelling property is also very undesirable.And adopt the coating gloss of the powder coating that the acrylic resin contain epoxide group and linear low acid value vibrin obtain as base-material (Chinese patent application number 00117364.2 introduce) can drop to below 5% (60 °), has excellent weathering resistance in addition, but it exists scratch resistance poor, and gloss control is shortcoming such as difficulty relatively.After mainly the showing as hard thing and streak the lower surface of gloss of scratch resistance difference, gloss raises, and influences outward appearance.
Summary of the invention: the invention provides that a kind of prescription is simple, technology convenience, gloss may command, scratch resistance outdoor low brightness paint powder and preparation method thereof preferably.The outdoor low brightness paint powder of the present invention comprises with the low acid value carboxyl polyester resin of a kind of linearity as base-material, and a kind of epoxy group(ing) acrylic resin can not add other delustring auxiliary agent in addition as solidifying agent.In this powder coating, the mol ratio of epoxy group(ing) and carboxyl is 0.5: 1～2.0: 1.This powder coating major ingredient comprises:
