Description
Technical field
The present invention relates to a kind of plastic cement vacuum plating method and used UV thereof oil, be meant the method and the used UV oil thereof of a kind of Vestolen PP 7052 (the English PP of abbreviation) plastic cement vacuum plating especially.
Background technology
At the numerous for example bottle caps of industries such as cosmetic package, electronics, loudspeaker, earphone etc., be the PP plasthetics, need spraying UV oil (ultraviolet light polymerization lacquer), vacuum plating in the course of processing.Present production process is generally, and carries out flame treating earlier, sprays behind the PP treatment agent oil at the bottom of the spraying UV again, and vacuum plating sprays UV face oil more then.Because the surface tension of non-polar polymeric materials such as PP plastic cement is low, coating difficulty on the PP plastic cement is adhered to, and the flame article are handled can improve its surface tension, significantly improves plastic cement wetting of surfaces performance, forms active surface.Strengthen ADHESION OF PAINTS power.But this technology will be used naked light at painting workshop, does not meet the security against fire requirement; Flame high temperature is prone to make PP plastic deformed simultaneously, and ageing-resistant, the anti-use properties of plastic cement is reduced.
Summary of the invention
The purpose of this invention is to provide a kind of PP plastic cement vacuum plating method, utilize this method effectively to simplify working process and technology, make spraying produce safer, technology is simple, operation is few.Another object of the present invention provides oil at the bottom of a kind of PP treatment agent that is used for PP spare and the supporting UV, and use should can be removed the flame treating operation from by oil, and product percent of pass is high, and product quality and visual appearance are high.
Designed a kind of PP plastic cement according to above-mentioned purpose and used the vacuum plating method, steps of the method are,
(1) PP plastic rubber material workpiece surface cleaning back gets into automatic coating machine spraying PP treatment agent;
(2) oil at the bottom of the automatic coating machine spraying vacuum plating UV;
(3) cross the UV machine;
(4) vacuum plating and check;
(5) automatic coating machine spraying vacuum plating UV face oil;
(6) cross the UV machine;
(7) check and finished product packing.
Use the vacuum plating method according to above-mentioned PP plastic cement, the composition component of PP treatment agent matched with it is that the polyolefine of toluene and band functional group, the weight percent of said composition component are toluene 75～90, the polyolefine 10～25 of band functional group.Wherein, the polyolefine of band functional group is hydroxyl Chlorinated Polypropylene III, and cl content 23 ± 2%.
According to above-mentioned PP plastic cement with the vacuum plating method with the supporting UV of PP treatment agent at the bottom of oil; This end oil composition component is toluene, vinyl acetic monomer, YLENE, polyester acrylate resin, pure acrylic acid ester resin, reactive monomer TMPTA (i.e. the english abbreviation of three vinylformic acid trishydroxymethyl propyl ester), the agent of esters of acrylic acid advection, SULPHOSUCCINIC ACID ESTER sticking power auxiliary agent, light trigger.Wherein, the weight percent of oil component is toluene 15～18 at the bottom of each UV; Vinyl acetic monomer 20～28, YLENE 5～9, polyester acrylate resin 12～25; Pure acrylic acid ester resin 12～18, reactive monomer TMPTA 11～18, esters of acrylic acid advection agent 0.1～0.2; SULPHOSUCCINIC ACID ESTER sticking power auxiliary agent 1.0～2.0, light trigger 5～8.Wherein, said polyester acrylate resin is that molecular weight is about 20000～30000 acrylic ester polymer, and said pure acrylic acid ester resin is the DR-A801 of Changxing chemistry, and said reactive monomer TMPTA is the EM231 of Changxing chemistry.In the said light trigger, the TPO of magnificent titanium accounts for 1～2 of end weight of oil per-cent, and the DBK of magnificent titanium accounts for 4～6.
The present invention can remove the production process of flame treating from practicality, do not have naked light, meets the security against fire requirement; Improved the ageing-resistant and durability of PP plastic cement than prior art; Make PP plastic cement vacuum plating procedure section economize operation, raise the efficiency and accepted product percentage.
Embodiment
The invention discloses a kind of PP plastic cement and use the vacuum plating method, steps of the method are,
(1) PP plastic rubber material workpiece surface cleaning back gets into automatic coating machine spraying PP treatment agent;
(2) oil at the bottom of the automatic coating machine spraying vacuum plating UV;
(3) cross the UV machine;
(4) vacuum plating and check;
(5) automatic coating machine spraying vacuum plating UV face oil;
(6) cross the UV machine;
(7) check and finished product packing.
Use the vacuum plating method according to above-mentioned PP plastic cement, the composition component of PP treatment agent matched with it is that the polyolefine of toluene and band functional group, the weight percent of said composition component are toluene 75～90, the polyolefine 10～25 of band functional group.Wherein, the polyolefine of band functional group is hydroxyl Chlorinated Polypropylene III, and cl content 23 ± 2%.
