Description

A kind of PET plastic cement vacuum plating UV dope

Technical field

The present invention relates to technical field of coatings, particularly relate to a kind of PET plastic cement vacuum plating UV dope.

Background technology

UV coating is the general designation of all solidified by ultraviolet ray radiation coating, and its thin film-forming method is that uviolizing causes insatiable hunger and closes double bond open chain polyreaction and drying and forming-film rapidly, need not special process, good combination property; Namely the coating that paint film is thinner has very outstanding fullness ratio; Sticking power is good especially; Gloss is very high.

PET material (polyethylene terephthalate chemical formula is-OCH2-CH2OCOC6H4CO-English name: polyethyleneterephthalate) is relative to widely used ABS material (acrylonitrile-butadiene-styrene copolymer, English name: AcrylonitrileButadieneStyrene), because it has excellent physical and mechanical properties in wide temperature range, life-time service temperature can reach 120 DEG C, electrical insulating property is excellent, creep resistance, resistance to fatigue, rub resistance, dimensional stability is all fine, and not easily decompose and obtaining extensive application at food packaging applications in recent years.But PET material surface tension is extremely low, it is very difficult for doing coating thereon, and a lot of factory will adopt pretreating reagent, corona or chromic acid process when application PET material, otherwise difficulty has good attachment.And more existing PET coating on market, have that levelling is poor, fullness ratio is not good, toughness is not good enough more or less, false attachment (attachment is at that time good, and after a couple of days, test comes off), upper plating be poor, the problems such as coloured silk sent out by coating.

China Patent No. is separately had to be: 201310176986.3, publication date is 2013.9.25, disclose a kind of UV coating for UV layout reproducing holographic pattern and using method thereof, UV coating comprises Type B coating and A type coating, Type B coating is made up of low-viscosity polyester acrylate, silicon modified polyesters acrylate, urethane acrylate, monomer, auxiliary agent and light trigger, and A type coating is made up of urethane acrylate, low-viscosity polyester acrylate, monomer, auxiliary agent, light trigger.Type B coating is added drop-wise between holographic nickel version and transparent PET base material, treatedly obtains transparent holographic lamina membranacea; Again A type coating is added drop-wise between transparent holographic lamina membranacea and transparent PET base material, treatedly copies transparent holographic plate; Carry out repetitive operation and obtain the large plate of transparent holographic; Metalized is done to the paint solidification layer of the large plate of transparent holographic, obtains the holographic special mother matrix of wide cut.This UV coating is good to plastic basis material attachment, and to holographic nickel version poor adhesion, scratch resistance, solvent resistance are good, is beneficial to the hologram pattern copied completely in transfer nickel version.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, a kind of PET plastic cement of the present invention vacuum plating UV dope, its objective is the UV Vacuum Deposition priming paint providing and PET plastic rubber substrate is had to excellent adhesion.

In order to solve the problems of the technologies described above, the technical solution used in the present invention is:

A kind of PET plastic cement vacuum plating UV dope, it is characterized in that: the component comprising following weight percent: polyurethane-modified acrylated oligomer 10-25%, polyester acrylate 10-20%, Viscoat 295 5-15%, alpha-hydroxycyclohexylbenketone ketone 1.5-4%, 10% vinylformic acid functional resins 1-8%, methylethylketone 2-15%, ethyl acetate 35-50%, N-BUTYL ACETATE 5-20%, cyclohexanone 1-8%.

A preparation method for PET plastic cement vacuum plating UV dope, comprises the steps:

(1) successively by polyurethane-modified acrylated oligomer, polyester acrylate, after Viscoat 295 is prepared in proportion, stirs 20-25 minute with the speed of 600-800rpm, is dispersed to uniform mixture in dispersion machine.

(2) by alpha-hydroxycyclohexylbenketone ketone, 10% vinylformic acid functional resins, methylethylketone, ethyl acetate, N-BUTYL ACETATE cyclohexanone is mixed in proportion, and adds in step (1) under lucifuge condition, in dispersion machine, stir 10 minutes to mixing completely and dissolving with rotating speed 600rpm.

Inspection declaration, qualified rear use 400 order filter screen filtration are packed.

Performance index of the present invention:

Adherence: 0 grade (PET)

Resistance to dimethylbenzene: >=3 minutes (dripping examination)

Alcohol resistance: >=100 times (ethanol 500g power)

Dry heat resistance: 168hrs(60 DEG C, related aluminium coated, coating oil is tested together), non-foaming, not loss of gloss
