Black general-purpose color masterbatch for automobile repairing paint
Technical field
The invention belongs to the coating material production technical field, be specifically related to a kind of black general-purpose color masterbatch for automobile repairing paint.
Background technology
Because automobile is the outdoor vehicles, often to bear the wind and weather sun and shine, run at high speed and the destruction of extraneous various mechanical forces, also make the maintenance of automobile and maintenance become the problem that must will face.Therefore the repairing of automobile becomes a problem that must solve, and the car refinishing paint of Xing Chenging also develops rapidly thus.
What the domestic automobile retouching paint at first entered car retouching paint market is the fixation lacquer, because domestic at that time car has only vehicles such as Santana, Jetta, Xiali, accounts for 80% of market for automobiles.Fixation lacquer is easy to use, but color fixes, so the limitation of existing.Along with increasing of vehicle, the fixation lacquer more and more is difficult to meeting the market requirement.
2000, China's car retouching paint formally entered with look female tinting system and repairs market.The look mother system is the core technology of retouching paint, it normally is prepared into mill base the solid-shade paint (being the look mother) that has greater concn than the fixation lacquer, solid-shade paint (being the look mother) by different colours accesses the needed fixation lacquer of client then, greatly facilitates the repairing of various cars.
Though but compare with the fixation lacquer of general in the market look female had very big versatility, but along with becoming increasingly abundant of automobile kind color, pearlescent lacquer, metallic paint, chameleon coating etc. more and more widely be applied to painting dressing automobiles, original look parent is also increasing, has produced plain color lacquer look female and metallic paint look female two kinds of systems accordingly.And can't be general between these two kinds of look parent systems, still exist limitation.
Chinese patent application CN101085888A discloses a kind of general color paste that is used for solvent ink, this general color paste adds aldehyde ketone resin, environment-friendly type acetates solvent, high molecular hyper-dispersant and surface treatment agent by pigment and forms, wherein pigment accounts for 25~80%, the aldehyde ketone resin accounts for 5~32%, esters solvent accounts for 10~40%, dispersant A account for 1~9% or dispersant B account for 1~6%, surface treatment agent accounts for 0~5%.Wherein black color paste is by 35% high-carbon black pigment, 26% cyclohexanone-formaldehyde condensation resins, 32% vinyl acetic monomer and 7% dispersant A (being the high-molecular block copolymer of commodity Solsperse 24000 by name).What but the preparation of this black color paste was adopted is single solvent, and single solvent exists limitation big, the shortcoming of the property taken into account difference.
Summary of the invention
The objective of the invention is to overcome the problems referred to above, a kind of not only satietin colored paint toning is provided but also satisfies the black general-purpose color masterbatch for automobile repairing paint of metallic paint toning, it has simplified the complicacy of tinting system, has effectively reduced the occupancy of resource.
The technical scheme that realizes the object of the invention is: a kind of black general-purpose color masterbatch for automobile repairing paint is characterized in that being made up of following components by part by weight: 15~30 parts of black color pastes, 37~47 parts of filmogens, 33~38 parts of look female mixed solvents, 0.2~0.8 part of look female mixed aid; Wherein black color paste is made up of following components by part by weight: 34~40 parts of aldehyde ketone resins, 8~16 parts of black pigments, 32~39 parts of mill base mixed solvents, 10~20 parts of mill base auxiliary agents.
The preparation method of black color paste is: aldehyde ketone resin, black pigment, mill base mixed solvent, mill base auxiliary agent are thrown together to charging tank disperseed to stir evenly, be ground to fineness less than getting final product below the 10 μ m with sand mill then.
Black look mother's preparation method is: black color paste, filmogen, look female mixed solvent, look female mixed aid are thrown together to charging tank disperseed to stir 20~30 minutes, mixing of materials is evenly got final product.
Described black pigment is a high-carbon black pigment.
Described mill base mixed solvent is two kinds or three kinds in dimethylbenzene, S100 solvent oil, the 1-Methoxy-2-propyl acetate.
Described mill base auxiliary agent is a modified polyacrylate superpolymer class carbon black dispersant.
Described filmogen is a kind of in Hydroxylated acrylic resin, the polyester modification acrylic resin or two kinds.
Described look female mixed solvent is two kinds or three kinds or four kinds in toluene, dimethylbenzene, 1-Methoxy-2-propyl acetate, N-BUTYL ACETATE, vinyl acetic monomer, the S100 solvent oil.
Described look female mixed aid is two kinds or three kinds in organic silicon modified by polyether flow agent, polyacrylate flow agent, fluorine-carbon modified polyacrylic ester superpolymer flow agent, the dibutyl tin dilaurate.
The color that black general-purpose color mother of the present invention can repair according to client's needs mixes according to the look mother of formula rate and other colors, can repair automobile.
The present invention has positive effect: mixed solvent has all been adopted in (1) black color paste of the present invention, black general-purpose color mother's preparation, taken into account the factor of economy several respects of the wettability of consistency, pigment of system and manufacturing processed, compare with single solvent, have better reasonableness; (2) black general-purpose color masterbatch for automobile repairing paint of the present invention can replace the female and metallic paint black look mother of the pitch-dark look look of original plain color, simplified the complicacy of tinting system, reduced tank farm stock, reduced handling cost, reduce the resource occupation rate, can satisfy the situation that the car color is enriched constantly and changed.All be guaranteed to the stability of system with the intermiscibility of various types of resins (metallic paint of CAB thermoplastic propene acid system and the plain color of two-component polyurethane systems lacquer), versatility is wide.
