Abstract
The invention relates to a powder coating with a low-temperature curing function. The powder coating comprises the following components in percentage by weight: 40-60 percent of unsaturated polyester resin, 20-25 percent of epoxy resin, 1-5 percent of photosensitizer, 0.5-1.5 percent of flatting agent, 0.1-1 percent of defoaming agent, 15-25 percent of filler, 8-15 percent of transparent iron oxide pigment and 0.1-0.5 percent of white carbon black. The powder coating with alow-temperature curing function is high in transparency, bright in color and low in curing temperature; when the powder coating is sprayed, the powder coating is preheated to 50-70 DEG C and maintained at the temperature for 5-8min, then subjected to electrostatic spraying, blown by hot air with the temperature being about 120 DEG C for 20min and then naturally cooled; and the powder coating is suitable for coating of wooden materials.
Description
Technical field
The present invention relates to a kind of powder coating, relate in particular to a kind of low-temperature curable powder coating.
Background technology
Because the various advantages of powder coating, its purposes in modern society is more and more extensive.Powder coating does not have water, does not have solvent yet, is solid fully, convenient transportation; Do not have germy infection, do not need to add sanitas; Be coated with and install fast that rear smell leaves.Because these advantages of powder coating, its purposes in modern society is more and more extensive.But the condition of cure of general powder coating is 150～180 ℃, and what have has reached 200 ℃, and this is unfavorable for the raising of production efficiency so that the application of some timber, plastics has produced difficulty.Simultaneously, if the shortcoming such as powder coating on the market is used for the application of furniture, and it is high to lack transparency, and color and luster is not bright-coloured.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned prior art, a kind of low-temperature curable powder coating is provided, can be used for the application of timber.
Technical scheme: a kind of low-temperature curable powder coating, contain by weight percentage following composition: unsaturated polyester resin 40～60%, Resins, epoxy 20～25%, photosensitizers 1～5%, flow agent 0.5～1.5%, defoamer 0.1～1%, filler 15～25%, transparent iron oxide pigment 8～15%, white carbon black 0.1～0.5%.
Low-temperature curable powder coating described above contains following composition: unsaturated polyester resin 45%, Resins, epoxy 20% by weight percentage, photosensitizers 3.5%, flow agent 1.5%, defoamer 0.5%, filler 20.5%, transparent iron oxide pigment 8%, white carbon black 0.1%.
Unsaturated polyester resin described above is metaphenylene unsaturated polyester resin.
Resins, epoxy described above is the glycidyl ester based epoxy resin.
Filler described above is that process white, talcum powder, kaolin, mica powder and silica powder mix.
Transparent iron oxide pigment described above contains following composition by weight percentage: ferrous sulfate 10.8%, water 87.9%, Sodium hexametaphosphate 99 0.045%, Sodium dodecylbenzene sulfonate 0.54%, ammonia 0.715%.
Beneficial effect: low-temperature curable powder coating provided by the invention, transparency is high, color is vivid, and solidification value is low, in spraying process, to object thermal pretreatment to 50～70 ℃, kept 5～8 minutes, and carried out electrostatic spraying, again the hot blast 20min through about 120 ℃, naturally cooling and get final product is applicable to the application of timber.
Embodiment
Embodiment 1
1. the preparation of transparent iron oxide pigment of the present invention: agitator is being housed, thermometer, in the four-hole boiling flask of bubbler, add first entry 75%, under agitation add ferrous sulfate 10.8%, and pH value of solution transferred to 2～3, be heated to about 40 ℃, add in the water of the residue 12.9% that is dissolved with Sodium hexametaphosphate 99 0.045% and Sodium dodecylbenzene sulfonate 0.54%, after stirring, pass into the air that is mixed with ammonia, obtain trickle ferric hydroxide colloid solution, then input air obtains nucleus, solution is warming up to 50～60 ℃ again, continue to pass into the air that is mixed with ammonia, obtain finished product.
2. the preparation of low-temperature curable powder coating of the present invention: with unsaturated polyester resin 45%, Resins, epoxy 20%, photosensitizers 3.5%, flow agent 1.5%, defoamer 0.5%, filler 20.5% and transparent iron oxide pigment 8% add mixing machine, rotating speed is 600r/min, drop into forcing machine after 5min gets the homogeneous material, then mixing melting homogeneous places shredder, add white carbon black 0.1%, speed lapping under 1000 r/min is the screen cloth of 100 μ m after pore size, namely gets powder coating.
Low-temperature curable powder coating provided by the invention can low-temperature curing, good dispersity, and lovely luster is applicable to the application of timber, such as the medium density fibre board (MDF) of the usefulness such as cabinet, furniture, also can be used for the application of plastics.
The above is the preferred embodiments of the present invention, but the present invention also is not limited to above only embodiment, slightly does improvement and also will be considered as protection scope of the present invention on embodiment.
