Description
Technical field
The present invention relates to a kind of solvent-borne type nanometer carbon black tinting material, the nanometer carbon black tinting material that particularly relate to a kind of UV of being applicable to vacuum metallizing coating, high temperature resistant, the transparency is high, metallized dye can be replaced.
Background technology
Metal, alloy and compound, mainly through methods such as vacuum evaporation, sputtering, ion platings, are plated on material or product surface by vacuum plating, form the coating required by product.Vacuum coating technology is widely applied in each fields such as electronics, aerospace, optics, magnetics, building, machinery, packaging, decorations, and plays increasing effect.Vacuum plating is a kind of CVD (Chemical Vapor Deposition) method, and organic coating is normally formed through film-forming by the organic polymer masking liquid applied, and is widely used in plastics, the protection of non-ferrous metal matrix surface and decoration.Organic polymer masking liquid be solidified with multiple method, the coating of ultraviolet light polymerization (abbreviation photo-cured coating) is wherein used day by day to be subject to showing great attention to of people, its principal feature is: curing speed is fast, only needs seconds or tens of seconds just completely curable under usual ultraviolet lamp radiation; Environmentally friendly, when illumination, major part or most compositions participate in crosslinking polymerization and enter rete; Save energy, UV photocuring energy used is about 1/5 of solvent based coating; Can the various base material of application, avoid the damage because high temperature during thermofixation may cause thermo-responsive base material (as plastics, paper or other electronic components etc.); Save mass energy, simplify operation, significantly reduce plant area etc., thus reduce production cost; As can be seen here, photo-cured coating and the application in vacuum plating industry thereof have broad prospects.The also employing metallized dye in current vacuum plating photo-cured coating there being mill base used, there is such as heavy metal severe overweight in this dyestuff, temperature tolerance, light permanency, resistance to migration are poor, can not meet the requirement of technique for vacuum coating technology.In electron trade as mobile phone, computer material therefor are mostly the non-ferrous metals such as plastics, aluminium alloy, zinc alloy, phone housing coating easily comes off, sweat proof poor water resistance, color for some time is with regard to variable color, this requirement is selective to the resin of vacuum metallizing coating, and has higher requirement to dispersion resin, dispersion agent in vacuum metallizing coating tinting material used.On domestic market, vacuum metallizing coating tinting material used is almost imported product entirely.
CN103013230A discloses a kind of preparation method of solvent-borne type nanometer carbon black mill base, and its basic recipe is: CAB resin 6% ~ 20%, wetting dispersing agent 3% ~ 15%, carbon black pigment 6% ~ 25%, solvent 65% ~ 80%; The particle diameter D of described solvent-borne type nanometer carbon black mill base
50control between 40 ~ 150nm.This nanometer carbon black mill base has the features such as package stability is good, tinting strength is high, the transparency is high, consistency is good, can replace metallized dye.Be widely used in the covering with paint tinting material of the package material surface such as toy for children, furniture, leather cloth products, plastics, metal products, metal coiled material, aluminium foil film and plating glued membrane, tobacco bale, candy, food, paperboard, also can be used as the transparent colourising agent of gilding film, glasswork, high-class metal baking vanish, plastics baking vanish, UV vacuum metallizing coating, and the tinting material such as marking ink and air brushing.This patent is also proposed by present patent application person, but poor with the consistency of UV vacuum metallizing coating.
Therefore develop a kind of environmental protection, transparent, high-performance, consistency are good, can metallized dye be replaced, and the solvent-borne type nanometer carbon black tinting material that can be used for UV vacuum metallizing coating is especially necessary.
Summary of the invention
UV vacuum metallizing coating resin used is reactive oligomers unsaturated polyester, polyester acrylate, polyether acrylate, epoxy acrylate and urethane acrylate etc., reactive thinner used is mostly acrylic ester monomer, therefore the present invention selects hydroxyl acrylic as dispersion resin, Hydroxylated acrylic resin has good consistency and the transparency, the sticking power to plastics and aluminium, zinc, copper, silver-colored ground can be improved, accelerated solvent, from the release paint film, shortens time of drying; Because hydroxyl acrylic contains hydroxyl, give film snappiness, colour stability and gloss retention.
The UV vacuum metallizing coating selectivity of solvent-borne type nanometer carbon black tinting material to dispersion agent used is high, because dispersion agent plays a part very important to the stability of tinting material, consistency, tinting strength.Therefore the wetting dispersing agent of the present invention polypropylene ester macromolecule dispersing agent of selecting TEMPO technology to synthesize, as EFKA-4320, EFKA-4330, such dispersion agent has absorbed portion and the expandable part in a solvent of pigment, absorption firmness is strong, adsorbent layer thickness is large, thus has good space steric effect.Therefore the nanometer tinting material made has the features such as package stability is good, strong coloring force, the transparency is high, consistency is good.
