Description
Technical field
The present invention relates to powder coating technology field, be specifically related to a kind of motor spring powder coating.
Background technology
Powder coating originates in the later stage thirties 20th century, and blank the earliest utilizes flame spraying to be sprayed on metallic surface with molten state by polyethylene powders.
Along with popularizing of automobile, automobile industry is fast-developing, thermosetting powder coating(s) relies on its own advantages to enter vehicle spray painting field, and motor spring, as security component, requires that attachment coating in its surface takes into account weathering resistance, water tolerance, salt fog resistance and high adhesive force; And existing powder coating often can not take into account salt fog resistance and weathering resistance, meanwhile, operationally the moment is kept in motion motor spring, therefore requires very high to the snappiness of paint coatings and metal substrate, ply adhesion.
Summary of the invention
Object of the present invention is to solve the problem, and provides a kind of and takes into account salt fog resistance and weathering resistance, motor spring powder coating with metal substrate strong adhesion.
The technical scheme that the present invention solves the problem is as follows:
A kind of motor spring powder coating, by following raw materials according by weight fraction scale form:
Resin, median size 30-40 micron, the polymerization degree is less than 650500-700 part;
Solidifying agent 35-55 part;
Color stuffing 300-400 part;
Softening agent 1-10 part;
Micronization wax 1-25 part;
Thermoplastic resin 5-50 part;
Defoamer 1-100 part;
Linking agent 1-100 part.
Micronization wax has strong-hydrophobicity, and add water resisting property, weathering resistance and the erosion resistance that can increase coating in powder coating to, moisture not easily contacts with metal substrate through coating with polar material; Defoamer can reduce the said minuscule hole of powder coating, makes coating finer and close, coordinates micronization wax to strengthen the erosion resistance of coating further.
Research shows, thermoplastic resin has the performance by thermal softening, hardening by cooling, and not easily react with, and this performance can by stable maintenance, form primary valence power between chemical bond on its polar group had and metal base, strengthen the sticking power between coating and spring base material.
Meanwhile, thermoplastic resin can fill the hole only deposited in coated material adding man-hour, strengthens its compactness, coordinates defoamer, linking agent and micronization wax to strengthen weathering resistance and the erosion resistance of coating.
The resin of low polymerization degree is due to its molecular weight, and levelling property is also better, and above-mentioned micronization wax, thermoplastic resin, defoamer and linking agent more to be dispersed in wherein to play a role better, make the powder coating of easier application.
Preferred as technique scheme, described resin is the one in epoxy resin, vibrin, polyacrylic resin.
Preferred as technique scheme, described linking agent is the mixture of one or more in DCP, BPO, DTBP, DBHP.
Preferred as technique scheme, described defoamer is the one in amide waxe defoamer or polypropylene, polyethylene wax defoamer or polyoxyethylene defoamer.
Preferred as technique scheme, described solidifying agent is the one in hydroxyalkyl amide, polyprotonic acid glycidyl ester, oxazoline, hydroxyl polyester, glycidyl methacrylate.
Conventional triglycidyl isocyanurate (TGIC) solidifying agent has certain toxicity, therefore selects the thing product as an alternative such as environment amenable hydroxyalkyl amide, polyprotonic acid glycidyl ester, oxazoline, hydroxyl polyester, glycidyl methacrylate.
Preferred as technique scheme, described thermoplastic resin is N-BUTYL ACETATE.
N-BUTYL ACETATE molecular weight, solubility property is good, is a kind of excellent organic solvent, is suitable for use as the preparation of powder coating; And the polar group that its unit weight comprises is more, the sticking power of powder coating can be improved preferably.
Preferred as technique scheme, described softening agent is phthalate compound or aliphatic dibasic acid ester compound.
The coating that the present invention produces, through weathering resistance (ultraviolet accelerated deterioration) test, within 720 hours, film layer is unchanged; Antifatigue tests more than 150000 times; Test through resistance to neutral salt spray test, 720 as a child film layer was unchanged; The sticking power adopting cross-hatching test is 0 grade, can meet the requirement of motor spring powder coating.
Powder coating of the present invention is manufactured by production technique well-known to those skilled in the art: namely lead expect-weigh-premix-melt extrude-compressing tablet-coarse reduction-fine powder is broken-detect-packing-warehouse-in.
In sum, the present invention has following beneficial effect:
1. a kind of motor spring powder coating of the present invention takes into account salt fog resistance and weathering resistance;
2. the strong adhesion of a kind of motor spring powder coating of the present invention and metal automobile spring ground.
