Abstract
The invention discloses an electrostatic coating powdered paint and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing 60-70wt% of polyester resin, 4-5wt% of curing agent, 25-40wt% of filler, 0.1-2wt% of pigments, 2-6wt% of adjuvant agents and 0.3-0.8% of a curing accelerant, extruding at the temperature of 90-100 DEG C, cooling, performing tablet compressing, smashing, and grinding to obtain a product with the medium particle size of 30-36 microns. The coating has a smooth appearance after being cured for 15min at the temperature of 170 DEG C, so that the devices and the energy consumption are greatly reduced.
Description
Technical field
The present invention relates to a kind of coating, especially a kind of electrostatic coating powder coating and preparation method thereof.
Background technology
Powder coating is due to the advantage such as environmental protection, easy construction, and Application Areas and scope expand gradually, substantially occupies the dominant advantage sprayed outside metal.But the baking having to pass through about 200 DEG C temperature and 15-20 minute after the powder paint of prior art could be solidified, equipment and energy consumption large; Simultaneously the powder coating coating anti-static effect of prior art is bad, therefore, studies that a kind of set time is short, solidification value is low, the electrostatic coating powder coating of coating energy anti-electrostatic and preparation method thereof, is the current technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of set time is short, solidification value is low, the electrostatic coating powder coating of coating energy anti-electrostatic and preparation method thereof.
The formula technique scheme that the present invention solves its technical problem is:
Electrostatic coating powder coating, its moiety is respectively by weight percentage: the vibrin of 60-70%, the solidifying agent of 4-5%, the filler of 25-40%, the pigment of 0.1-2%, the auxiliary agent of 2-6%, 0.3-0.8% curing catalyst.
As a kind of preferred version of formula technique scheme of the present invention, its moiety is respectively by weight percentage: the vibrin of 65%, the solidifying agent of 5%, the filler of 30%, the pigment of 0.6%, the auxiliary agent of 4%, 0.3% curing catalyst.
As a kind of preferred version of formula technique scheme of the present invention, described filler comprises barium sulfate, titanium dioxide and wax powder; Described auxiliary agent comprises flow agent, st-yrax and UV light absorber.
As a kind of preferred version of formula technique scheme of the present invention, described filler is 19% barium sulfate, 7% titanium dioxide and 0.6% wax powder, and described auxiliary agent is 0.8% flow agent, 0.8% st-yrax and 1% UV light absorber.
Preparation method's technical scheme that the present invention solves its technical problem is:
The preparation method of electrostatic coating powder coating, its processing step is:
1. according to the various starting material of above-mentioned formula rate precise, import in convertible automatic mixing machine and mix, mixing time is 8-10 minute;
2. use twin screw extruder to be extruded by the material melts mixed, extrusion temperature is 90-100 DEG C;
3. the material format roll extruded is depressed into 1-2mm thin slice, cooling on transmission steel band is also pulverized with breaker roll;
4. by waking up with a start classification and pulverizing in sheet stock blow-off valve to flour milling unit;
5. the stainless steel mesh through cyclonic separation and special order number isolates product;
6. use laser particle analyzer testing product granularity, and get product and carry out electrostatic spraying 60-80 micron, put into high temperature drying case and carry out 170 DEG C, test after solidification in 15 minutes.
The middle particle diameter of powder is 30-36 micron, and main particle size distribution range is 10-50 micron; Coating thickness reaches outward appearance and the performance requriements that 60-80 micron just can ensure film, and due to solidification value low, the time is a little short, reduces equipment and energy consumption.
Compared with prior art, powder coating of the present invention has that set time is short, solidification value is low, the advantage of the electrostatic of coating energy anti-electrostatic.
specific implementation method
According to weight percent, by 65% vibrin, 5% solidifying agent, 0.8% flow agent, 19% barium sulfate, 7% titanium dioxide, 0.8% st-yrax, 1% UV light absorber, 0.6% pigment, 0.6% wax powder, 0.3% curing catalyst, extrude at 90-100 DEG C of temperature, cool compressing tablet, fragmentation, abrasive dust after obtain in the product of particle diameter 30-36 micron.Solidify 15 minutes at 170 DEG C of temperature after electrostatic coating, 60-80 micron coating thickness can be obtained.Flat appearance, gloss 88%, bending 2mm, direct impact strength 50cm, inverse impact strength 25cm, sticking power one-level, film pencil hardness 2H.
