The surface lacquer method of the electric shells of pen

Technical field

The present invention relates to the surface lacquer method of a kind of electric shells.

Background technology

Conventional P U sprays paint that production technology comprises pre-treatment, sprays coloured PU priming paint, baking-curing (general 1-2H), pre-treatment, spraying UV paint, ultraviolet photo-curing, test package.Flow process is complicated, and baking is long for drying time, and production efficiency is low, and ring surveys poor-performing, and service life is short; And traditional PU paints in the production process of joining, to be finished in its pot-life of several hours, otherwise will crosslinking curing, bring great inconvenience to construction, slightly misoperation, will waste be caused; In simultaneously traditional production technology, every procedure all can have the defective products of different proportion to produce, and operation is more, and defective products rate is higher.

Summary of the invention

The object of this invention is to provide the surface lacquer method of the high pen electricity shells of a kind of yields simple to operate.

For solving the problems of the technologies described above, the present invention adopts following technical scheme: the surface lacquer method of a kind of electric shells, and it comprises the following steps:

A, clean

First utilize cleaning agent to carry out oil removing to pen electricity shells, recycling electrostatic precipitator destatics and dust pen electricity shells, natural air drying 5 ~ 10s in a pipeline;

B, spraying

First coloured UV is painted: modulate according to weight ratio 1:1 with solvent, the viscosity of the paint modulated reaches following condition: at normal temperatures, No. 2 flow cup whole delivery times of rock field are 8 ~ 9 seconds, the spraying of UV paint is carried out in the dust free room that lustration class is at least 100,000 grades, the thickness that sprays paint is 8 ~ 15um, described coloured UV paint ingredients comprises by weight: pigment 20% ~ 30%, UV light-cured resin 30% ~ 45%, reactive diluent 20% ~ 30%, auxiliary agent 10% ~ 15%, light trigger 1% ~ 10%, described light-cured resin is polyurethane acrylic resin, described reactive diluent is UV monomer, described auxiliary agent comprises: anti-wear agent, corrosion resistant agent, levelling agent, defoamer, dispersant, rheology modified resin, anti-settling agent,

C, photocuring

Sent in ultraviolet photo-curing stove by automatic production line by pen electricity shells after spraying and be cured, hardening time is 1-3min, and ultraviolet energy is 300 ~ 800 MJs, and in-furnace temperature remains on 55 ~ 65 DEG C;

D, test package

Can directly to test after having solidified packaging.

Optimize, described anti-wear agent is silica glass microballon.

Optimize, described light trigger is made up of benzophenone, 1173 light triggers and TPO photoinitiator, wherein occupies the percentages that look UV paints by weight, and benzophenone accounts for 1% ~ 5% in UV paint, 1173 light triggers account for 2% ~ 10% in UV paint, and TPO photoinitiator accounts for 1% ~ 5% in UV paint.

Optimize, described levelling agent is alkyl-modified organosiloxane.

Optimize, described defoamer is organic modified polyorganosiloxane.

Optimize, described anti-settling agent is anti-settling wax.

Optimize, described solvent is butyl acetate or acetic acid butanone or both mixtures.

Beneficial effect of the present invention is: this production method decreases the main production process of multiple tracks, thus reduces the defective products of more than 20% procedure for producing, and curing rate is fast, substantially increases production efficiency, decreases manpower; Easy to use, the paint be not finished is so long as not under being exposed to high light, and sustainable use, does not have limit service life; Coloured UV paint is solid containing high, paint consumption is few, therefore the painting cost of coloured UV paint generally paints low 20%-50% than PU, a small amount of solvent volatilization in coloured UV use procedure, ingredient major part film-forming, be all minimum to the health hazard of constructing operation personnel and the pollution of environment, and coating is not containing formaldehyde, benzene, TDI heavy metal, is real Green Product.
