Description
Technical field
The present invention relates to the UV field of photo-curing coatings of coiled material, the first floor priming paint of specially a kind of metal coiled material UV coating and
Preparation method.
Background technique
Traditional coiled material paint is polyurethane baking vanish, epoxy amino type, epoxy polyurethane type, Amino-Polyester type and the poly- ammonia of polyester
Its construction of ester type causes great environmental pollution and energy waste often through being heated to 200-400 DEG C.And ultraviolet light solidification applies
Material and technology have the characteristics that 4E: excellent performance, energy-saving and environmental protection, economy.In response to society to the cry of environmental protection, have
Necessity is coating material solidified applied to coiled material by UV.However, coating adhesive force on base material is the prerequisite that coating can use.Volume
Material coating requires to include: scratch-resistant lattice, water boiling resistance and resistance to forward and reverse impact, specifically, scratch-resistant lattice will reach 0 grade, water boiling resistance
It is required that being not in broken skin or obscission by two hours boiling coatings, resistance to forward and reverse impact does not generate cracking after requiring impact
Or coating shedding.Different from metal adhesion with baking vanish polyurethane, adhesive force and its facilitation of the UV coating on metal are also
It is the oligomer of unknown, common some metal adhesion promotor such as phosphates, passes through phosphate group and metal reaction.I
Find in an experiment, phosphate adhesion promoter can only be added 1-3wt%, be added more and be unfavorable for boiling etc. instead
Requirement.In addition, these zones of action are that adhesive force is weak it has been found that " stain " can be left by acting on phosphate and metal
Point.As it can be seen that it is only far from enough come the design for carrying out metal UV photocureable coating by metal adhesion promotor, need new view
Angle carries out the exploitation of metal UV coating.
Marine mussel is a kind of aquatile, it can strongly be adhered to any under water by secreting a kind of adhesion protein
The surface of substance (various organic and inorganic matter), scientist is the study found that play adhesive attraction in marine mussel is similar poly- more
The substance (science, 318,426) of bar amine.It is various to cause whole world scientific worker progress for this feature of poly-dopamine
The upsurge of material surface modification.However, the research that dopamine is used for coiled material UV coating is not yet had been reported that.
Summary of the invention
The purpose of the present invention is to provide metal coiled material coating first floor priming paint of a kind of UV curable and preparation method thereof,
UV curable and there is extremely strong adhesive force on metal coiled material, can be used for the attachment of subsequent metal UV coating, solve UV coating in gold
Adhesive force Construct question on category.
The technical scheme is that a kind of first floor priming paint of UV curable metal coiled material coating, raw material in terms of mass parts,
Composition are as follows:
Diluting monomer: 30-65 parts；
1173:3-6 parts of photoinitiator；
Metal adhesion promotor: 30-80 parts；
Wherein, the diluting monomer is water-soluble oligomer EO15-TMPTA (15 ethoxylated trimethylolpropanes 3 third
Olefin(e) acid ester)；The metallic promoter agent is dopamine buffer solution.
The dopamine buffer solution is the aqueous dopamine solution for being added to sodium metaperiodate, with diluted alkaline adjustment pH value for 8
~12.
The concentration of dopamine is 40-500mg.L in the dopamine buffer solution-1, the concentration of sodium metaperiodate is 80-
1000mg.L-1。
The diluted alkaline is NaOH aqueous solution.
The method of the first floor priming paint of the preparation UV curable metal coiled material coating, each component is uniformly mixed, and is adjusted
To needing viscosity.
Using the method for the first floor priming paint of the UV curable metal coiled material coating, by the paint rolling applying on coiled material,
UV irradiates 1~5 minute, and the adhesive film of strong adhesive force is formed on metal.
First floor priming paint the answering in the metal coiled material of iron, aluminium or its alloy type of the UV curable metal coiled material coating
With.
The utility model has the advantages that
The cured coiled material first floor solidifying priming paint of UV prepared by the present invention is fast, and the adhesive force on metal coiled material is good, to subsequent
The compatibility and interfacial contact power of coiled material UV coating are good, effectively increase the coating material solidified adhesive force on metal coiled material of UV.
By the adjusting with sodium metaperiodate and sodium hydroxide, the pH value for controlling solution is kept dopamine in method of the invention
In alkalinity, to guarantee that dopamine in the presence of water-soluble diluent and photoinitiator, is radiated on coiled material by UV and forms densification
Coherent film.The coherent film has apparent compatibility and great adhesive force to UV coating.Here the dopamine polymerization generated
Object film, it is different from the effect of dopamine is added in other coating as the transition zone between coiled material and UV coating, such as patent
In CN107828328A modified aqueous polyurethane coating, what dopamine played the role of is surface aggregate modified graphene.
