A kind of preparation method of imitative crocodile skin coating, including crocodile skin priming paint, crocodile surface paint, crocodile skin enamel paint and crocodile skin handfeel paint Preparation, the preparation method of the crocodile skin priming paint is successively by acrylic resin, alkyd resin, melamine resin, alcohol Ethers mixed solvent, surface modifier, adhesion promoter, epoxy resin, mill base, mixed solvent are added to the container, and are mixed Uniformly obtained crocodile skin priming paint；
The preparation step of the crocodile surface paint is as follows: successively urging water-based acrylic resin, melamine resin, acid Agent, alcohol ethers mixed solvent, leather pattern effect auxiliary agent are added to the container, and are mixed 20 minutes to uniform, then with aqueous color Slurry and aqueous color accurate adjustment section color adjust viscosity to specified range up to the crocodile surface paint with water；
The preparation step of the crocodile skin enamel paint is as follows: successively by acrylic resin, high-solid lower-viscosity type acrylic resin, three Melamine-formaldehyde resin, surface modifier are added to the container, and are mixed 20 minutes to uniform, then with transparent ferric oxide mill base tune Color is saved, viscosity is adjusted to specified range up to the crocodile skin enamel paint with mixed solvent；
The preparation step of the crocodile skin handfeel paint is as follows:
Component A: successively acrylic resin, acetylbutyrylcellulose, surface modifier, feel auxiliary agent, mixed solvent are added In container, 20 minutes are mixed to uniformly up to the crocodile skin handfeel paint component A；
Isocyanate resin, mixed solvent: being successively added to the container by B component, is mixed 10 minutes to uniformly to obtain the final product The crocodile skin handfeel paint B component；
Then coating, the coating work are carried out to above-mentioned crocodile skin priming paint, crocodile surface paint, crocodile skin enamel paint and crocodile skin handfeel paint Skill are as follows:
The crocodile skin priming paint, priming paint surface drying after placing 30-45 minutes under normal temperature condition, spraying are sprayed in surface of bottom material first Crocodile surface paint, room temperature stands 60-90 minutes, until surface texture forms completely, goes to 60 DEG C of baking ovens and toasts 60 minutes, spray after cooling The crocodile skin enamel paint is applied, surface drying enters 130 DEG C of baking ovens after ten minutes and toasts 30 minutes, sprays crocodile skin handfeel paint, room temperature after cooling From dry 7 days.
By using preceding solution, the beneficial effects of the present invention are: the forming principle that the present invention imitates the coating of crocodile skin is Using film in drying process, shrinkage stress difference is reached between upper layer and lower layer coating.With traditional dermatoglyph coating Different places are that the present invention is poor not only through the shrinkage stress that the adjustment of PVC is exaggerated between priming paint and finishing coat, while benefit In the water-based acrylic resin thermoplasticity film forming procedure of high glass transition temperature, the hypodynamic feature of itself cohesion is formed special Different alligatoring effect.When finishing coat is in drying process, by adjusting volatilization gradient, can cause film in the horizontal direction by Power is uneven, so that stress be made to concentrate, the brittle fracture in horizontal direction will occur for paint film.By constantly adjusting, finally may be used It is very much like with the lines of this crackle broken to form and crocodile skin.Pass through the adjustment of priming paint, finishing coat, enamel paint color again, Make the color after arranging in pairs or groups each other close to crocodile skin, crocodile bark effect is imitated from color.Finally, by adjusting handfeel paint elasticity and Sense of touch, imitates crocodile bark effect in tactile, finally accomplishes perfectly to imitate crocodile skin decorating effect.
The imitative crocodile skin coating is mainly by crocodile skin priming paint, crocodile surface paint, and four kinds of coating of crocodile skin enamel paint and crocodile skin handfeel paint are taken With composition.Crocodile dermatoglyph shape is collectively formed in priming paint and finishing coat, and enamel paint is responsible for the modification of crocodile skin color, and handfeel paint is responsible for crocodile skin hand The imitated and outer layer protection of sense.In four kinds of coating, crocodile skin priming paint and crocodile skin enamel paint use acrylic resin as film Matrix resin, and be aided with melamine resin as high-temperature cross-linking agent, can be formed under the high temperature conditions three-dimensional netted Structure provides physical strength for film.The epoxy resin of different molecular weight is introduced in crocodile skin base paint formulation for film Toughening simultaneously improves paint film adhesion, and alkyd resin and part alcohol ethers solvent are used to adjust the rate of drying of crocodile skin priming paint, and In a manner of adjusting itself internal stress, effective control is done to the crack shape of crocodile surface paint, while improving and applying interlayer with upper layer Adhesive ability.The preferable transparent iron oxide pigment of weatherability is introduced in crocodile skin enamel paint, to modify and imitate the face of crocodile skin Color effect, and the three-dimensional sense of the acrylic resin increase film by collocation high solid content and low viscosity.Crocodile surface paint uses high glass The water-based acrylic resin of glass temperature is as matrix resin, and the melamine resin for being aided with methyl-etherified is handed over as high temperature Join agent, the effect of amphiprotic solvent and leather pattern effect auxiliary agent is to adjust rate of volatilization and control alligatoring size.Crocodile skin handfeel paint uses Two-component PU system, matrix resin be in low hydroxyl value acrylic resin, reacted and handed over using isocyanate resin as curing agent Join, acetylbutyrylcellulose and the collocation of different types of hand feeling agent are introduced in formula to adjust feel, reaches and imitates crocodile skin skin The effect of matter sense of touch.
