Abstract
The invention discloses a formula of a composite coating material. The formula of the composite coating material contains the ingredients by weight: 300g to 400g of polyester, 250g to 400g of epoxy, 0.5g to 1g of polyvinyl chloride resin, 6g to 8g of leveling agent, 285g to 300g of barium sulfate, 10g to 15g of sensitizer, 100g to 150g of titanium white, 3g to 5g of high-gloss wax, 2g to 5g of incense, 1.0g to 1.5g of power-increasing agent, 0.5g to 0.7g of carbon black, 0.15g to 0.25g of iron red and 0.2g to 0.4g of ferrite yellow. A coating film surface with excellent properties, such as coating film permanence can be obtained through baking and has rub resistance, impact strength, adherence, toughness, corrosion resistance, resistance to chemicals, and the like; the coating material further has high weather resistance and pollution resistance; and a coating film with the thickness of 50 to 300 microns can be prepared from a powdery coating material through one-time spray-coating, the leveling property is good, and the problem of solvent coating materials that phenomena of dripping or stagnating and the like occur during thick coating is solved.
Description
Technical field
The present invention relates to the formula of a kind of powdery paints.
Background technology
Powdery paints is a kind of novel without solvent 100% solid powdery coating. There is solvent-free, pollution-free, recyclable, environmental protection, the saving energy and resource, reduce labor intensity and film mechanical strength high.
At present, heat curable powder coating is using thermosetting resin as film forming matter, added the firming agent of cross-linking reaction heated after can form insoluble not molten quality hard coat, temperature this coating high again softens without as thermoplastic coating, and can only decompose, the resin adopted due to thermosetting powder coating is the prepolymer that the degree of polymerization is relatively low, molecular weight is relatively low, so the levelability of coating is better, there is good dicoration, and low-molecular-weight prepolymer cured after, the macromole of cross-linked network can be formed, thus coating has better anti-corrosive properties and mechanical performance, therefore thermosetting powder coating development is particularly rapid, but, in prior art, its powdery paints is by polyester resin, the different Fo Er copper diisocyanate of enclosed type, Benzoinum and dibutyltin dilaurate composition, its shortcoming is that physics characteristic is poor, coverage effect is poor, it is easily generated rill, electrical equipment spraying and top layer protection cannot be met.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned deficiency, it is provided that a kind of covering performance is good, levelability better, has good ornamental composite powder formula.
In order to solve above-mentioned technical problem, it is carried out by the following technical programs:
A kind of formula of composite coating, described composite powder formula is by polyester 300-400g, epoxy 250-400g, Corvic 0.5-1g, levelling agent 6-8g, barium sulfate 285-300g, optical brightener 10-15g, titanium dioxide 100-150g, high light wax 3-5g, fragrant 2-5g, growth agent 1.0-1.5g, carbon black 0.5-0.7g, iron oxide red 0.15-0.25g, iron oxide yellow 0.2-0.4g.
Preferably, described levelling agent is Siloxane-Oxyalkylene Copolymers copolymer.
Preferably, described optical brightener is methyl methacrylate and butyl acrylate copolymer.
Preferably, described growth agent is fatty acid and quaternary amine compound, and its melting point of its fatty acid is at 67 DEG C ~ 70 DEG C, and thermostability quaternary ammonium salts growth agent is ionic surfactant, and fatty acid and quaternary amine compound weight ratio are 1:1.
Adopting as above after technical scheme, it has the beneficial effect that
After taking above-mentioned formula, the toasted film coated surface that can obtain excellent performance, such as the persistency of film, including: rub, impact, adherence, toughness, corrosion resistance and chemical resistance etc. And the powdery paints of outdoor, except above-mentioned advantage, more include high-weatherability and stain resistance. Especially thicker film, powdery paints once sprays and can reach 50-300 ��m, and good leveling property, has and drip phenomenon generations such as hanging down or stagnate when will not be coated with as coatings volatile organic compounds thickness. Because powdery paints uses electrostatic principle spraying, coating equipment can reach full-automation, without waste of manpower resource.
