Abstract
The invention relates to a preparation method of solvent-based nano-carbon black paste. The solvent-based nano-carbon black paste comprises the following basic formation: 6-20% of CAB (cellulose acetate butyrate) resin, 3-15% of wetting dispersant, 6-25% of carbon black pigment and 65-80% of solvent; and the grain diameter D50 of the solvent-based nano-carbon black paste is controlled to be 40-150nm. The nano-carbon black paste has the characteristics of good storage stability, high coloring capability, high transparency, good compatibility and the like, can substitute metal complex dyes, is widely used as a surface coating colorant for packaging materials for children toys, furniture, leather and cloth products, plastic products, metal products, metal coils, aluminum foils and plating films, cigarette packets, candies, food, paper boards and the like, and can be also used as a transparent colorant for gold-stamped films, glass products, high-grade metal baking paint, plastic baking paint and UV (ultraviolet) vacuum coating paint, as well as a colorant for printing ink, jetting ink and the like.
Description
Technical field
The present invention relates to a kind of preparation method of solvent-borne type nanometer carbon black mill base, relate in particular to a kind of multi-usage, the transparency, can replace the nanometer carbon black mill base of metal complex black dyes.
Background technology
Dyestuff or metallized dye are adopted at present toy for children, leatherware, furniture, printed matter, marking ink or air brushing etc. mostly, most of dyestuffs exist such as the heavy metal severe overweight, to contain morbid substance, temperature tolerance, light permanency, resistance to migration poor, can not satisfy people to the pursuit of healthy living quality; Many goods are transparent to the coating specification height, high-performance, environmental protection etc., and standard-required is more and more higher, and the common dispersible pigment color paste transparency does not all meet technical requirements.Therefore develop a kind of environmental protection, the nanometer carbon black mill base that transparent, high-performance can replace the metal complex black dyes is especially necessary.
Summary of the invention
The present invention selects cellulose acetate butyrate (being called for short CAB) as dispersion resin, cellulose acetate butyrate has a wide range of applications at coating: add CAB in aluminium, copper, silver and other metallic paint, but the release of accelerated solvent from paint film, the tactile time of doing can significantly shorten; As flow agent, can improve levelling property, reduce shrinkage cavity, in the gas dried lacquer coating of thermoplastic propene's acid type, this performance is more outstanding; Because CAB contains hydroxyl, it can react with aminoresin in the presence of acid catalyst, the own hardness of impact neither, give again and filming with snappiness, and this varnish has good sticking power, glossiness and gloss retention, make the characteristic of the amino resin crosslinked existing crosslinked coating of CAB/, the rate of drying of gas dried lacquer is arranged again; CAB makes again levelling of paint film in the flow pattern coating again in heat, makes coating have high gloss, avoids necessary polishing operation; In wood coating, can avoid moist and cause swelling of wood or perk; In plastic paint, add CAB and can strengthen wear resistance, colour stability, increase toughness; Impel as much as possible the orientation of priming paint contraction and al powder flake when the adding of CAB helps solvent evaporates in vehicle paint base; In the coating varnish of automobile, add CAB, finishing varnish is coated after, avoid solvent to be penetrated into bottom, and make the automobile finish light attractive in appearance; CAB can shorten time of drying in the car refinishing paint system, improve cold-crack resistance, and have good polishing performance; Also have a wide range of applications in leather coating, ultraviolet-curing paint, CAB itself can be used for making transparent plastic ware attractive in appearance, but also can be used for making peelable material, chooses therefore that CAB is wide as the dispersion resin versatility of nanometer carbon black mill base, applicability is wide.
Nano color paste requires highly to dispersion agent, and stability of pigment paste, suitability are played very important factor.Therefore the present invention selects the block macromolecular multipolymer that contains the pigment affinity groups as dispersion agent, especially selects the macromolecule dispersing agent of controlled free-radical synthetic (CPT), as
4310,
4320, DISPERBYK-2000, DISPERBYK-2001, DISPERBYK-2020, DISPERBYK-2025, DISPERBYK-2026 etc., such dispersion agent has the absorbed portion of pigment and expandable part in solvent, the absorption firmness is strong, adsorbent layer thickness is large, thereby has good sterically hindered effect.Therefore the nano color paste of making has the characteristics such as package stability is good, tinting strength is high, the transparency is high, consistency is good.
In order to solve technical problem recited above, the present invention takes following technical scheme: the present invention relates to a kind of solvent-borne type nanometer carbon black mill base, 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 the nanometer carbon black mill base of making
50Be controlled between 40～150nm.
Wherein, the CAB resin is selected a kind of of the cellulose acetate butyrate resin that contains butyryl radicals 38%.
Wetting dispersing agent is selected the block macromolecular multipolymer that contains the pigment affinity groups, especially selects the macromolecule dispersing agent of controlled free-radical synthetic (CPT), as
4310,
4320, the one or more combination of DISPERBYK-2000, DISPERBYK-2001, DISPERBYK-2020, DISPERBYK-2025, DISPERBYK-2026.
Carbon black pigment is selected Mongul-L, REGAL400R, Monarch1300 or the Monarch900 of Cabot, the Special biack 4 of Degussa, Special biack 6, Special biack 550, FW18, FW285 or FW200, the MA7 of Mitsubishi Chemical, MA100 or #40, the Raven3500 of Colombia's chemistry, Raven1255 or Raven3600, and other high-carbon black pigment.
Solvent is chosen the combination with one or more of methylethylketone, n-butyl acetate, 1-Methoxy-2-propyl acetate, Diethylene Glycol monobutyl ether acetate, acetone, isobutyl acetate, propyl carbinol and methyl amylketone.
The present invention proposes a kind of preparation method of solvent-borne type nanometer carbon black mill base, preparation technology is as follows: add solvent, CAB, wetting dispersing agent by the formulation weight ratio, speed with 500r/min in high speed dispersor stirs, then under the high speed of 1000～1200r/min, add carbon black powder, high speed dispersion 45～60min, arrive again nano-dispersed machine circular grinding 8～12h, carry out granularity Detection every 0.5h with laser particle analyzer, until the particle diameter of mill base reaches requirement, filter and package and obtain solvent-borne type nanometer carbon black mill base.
The characteristics such as the solvent-borne type nanometer carbon black mill base package stability that the present invention makes is good, tinting strength is high, the transparency is high, consistency is good have high-performance, do not contain benzene and heavy metal, and multi-usage can replace metallized dye.Be widely used in the covering with paint tinting material on toy for children (wooden, five metals, plastics), wood furniture, leatherware surface, the covering with paint tinting material on plastics, metal products surface (such as mobile phone, household electrical appliances, cosmetic packaging bottle etc.), the covering with paint tinting material on metal coiled material, aluminium foil film and plating glued membrane surface, the covering with paint tinting material of the package material surface such as tobacco bale, candy, food, paperboard, (comprise the painted of hot transfer ink coating, characteristics: resistance to migration is strong for the covering with paint tinting material of the hot transfer printing product surfaces such as gilding film, leather cloth.) the transparent coating tinting material of glasswork coating, the tinting material of high-grade metal baking finish, plastics baking vanish, automobile finish etc., the transparent tinting material of UV vacuum metallizing coating, and the tinting materials such as marking ink and air brushing.
