Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of for being sprayed on that use temperature is higher and structure is more complicated, the electric heating installation using oil as medium powder coating of many angles, many grooves.
For this reason, technical scheme of the present invention is as follows:
A kind of electric heating installation using oil as medium powder coating, be made up of the component of following weight parts:
Wherein, the saturated polyester resin of described vibrin to be acid number be 72 ~ 78mgKOH/g, the epoxy resin of described epoxy resin to be epoxy equivalent (weight) be 710 ~ 875g/eq.
Described growth agent is polarity fatty acid ester growth agent, comprise short-chain aliphatic ester class growth agent and long chain fatty acid ester class growth agent, and the two weight ratio is 3 ~ 5:5 ~ 7.Two kinds of growth agents are by used in combination with certain proportion, and increase upper powder amount when being conducive to powder paint, overcome electrostatic shielding, even if element structure is complicated, angle dark, groove is many also evenly can go up powder, and without electrostatic shielding phenomenon.
Described auxiliary agent is the mixture of flow agent, air release agent, wax powder, anti-yellowing dose and growth agent.
Preferably, the weight ratio of described flow agent, air release agent, wax powder, anti-yellowing dose and growth agent is 2:1:1:2:2.
Preferably, described flow agent is acrylate flow agent.
Preferably, described wax powder is polytetrafluoro class wax powder.
Preferably, described air release agent is st-yrax.
Preferably, described anti-yellowing dose is anti-yellowing dose of phosphorous acid esters.
In described auxiliary agent, there is one to flow and drying and forming-film process after the interpolation of flow agent makes this powder paint, then progressively form smooth, smooth, a uniform film; Described air release agent makes the gas in coating process in application ground be easy to effusion, and the powder coating like this after solidification is smooth bright and clean, eliminates holiday; Described wax powder makes hand feel and drape after powder coating and their application; Described anti-yellowing dose add can suppress film yellowing effectively, also can stable reproduction in hot environment even if make film color be in for a long time.
Barium sulfate in described powder coating component is conducive to this powder coating as filler increases the scratch resistant effect of hardness when powder film forming.
Described pigment is the high-carbon black pigment MA100 that Mitsubishi pigment company limited produces, and this pigment plays to hide and increases gorgeous effect in formula.
This electric heating installation using oil as medium is simple by powder coating preparation technology, and by each component pre-mixing taken according to formula, the time is 4 ~ 6 minutes, extrudes in flakes at 90 ~ 105 DEG C of forcing machines, finally pulverizes and sieves and namely obtains described electric heating installation using oil as medium powder coating.
The powder average particle size of described powder coating is about 30 ~ 40um.
In the R&D process to this electric heating installation using oil as medium powder coating, when selected vibrin and epoxy resin type or charging capacity are slightly different, great performance difference will be produced.Therefore, contriver carries out test of many times through the various ingredients content proportioning of producing different company, obtains the formula of this electric heating installation using oil as medium powder coating.
This electric heating installation using oil as medium is simple by powder coating using method, when spraying device, after powder is put into fluidizing bucket, can start spraying with electrostatic power unit device.
The present invention selects suitable material, electric heating installation using oil as medium powder coating is obtained after being aided with corresponding additive mixing, this powder coating is not containing toxogen material, be applicable to spraying use temperature higher, the special component surface of complex structure, many angles simultaneously, and production technique and using method are simply, nontoxic non-environmental-pollution, cost is low, and economic and social benefit is remarkable.
