Abstract
The invention relates to an acrylic powder coating, resin and its preparation method, the solution polymerization is adopted in the invention, only use three kinds of conventional monomers to copolymerize and synthesize an acrylic resin containing epoxy group, then through adding various fillers, compounding chemicals, through processes such as hot melt mixing, pulverizing, etc., get a acrylic powder coating finally, can meet the industrial use requirement, said product and preparation method have with low costs, raw materials are apt, prepare the characteristics of simple process, stable performance.
Description
The present invention relates to resin combination and this powder coating and preparation method that a kind of novel preparation acrylic powder coating is used.
Acrylic powder coating is a kind of ornamental, open air property, and the coating that sticking power is superior because it does not use solvent, has overcome the poisoning that solvent brings, fire, fully to the shortcomings such as pollution of environment, thereby its use is more and more widely.Use in many fields such as household electrical appliance, bike, motorcycle, its usability is better than epoxide powder coating, even polyester powder coating.
The exploitation of acrylic powder coating, comparatively active in Japan, to open among clear 50--158621 and the clear 50--159518 of Te Kai as the Japanese Patent spy and to introduce the fourth acrylic powder coating, use therein film forming matter is by (methyl) acrylate that contains epoxy group(ing).(methyl) alkyl acrylate and other polymerisable monomer copolymerization form, and sneaked into other modified resin that contains glyceryl ester, to increase cross-linking density, though this method can make well behaved powder coating, but because used modified resin price is higher, domestic being difficult to obtains, and the powder process cost is risen, and be unreasonable economically.
Purpose of the present invention is exactly in order to reduce cost, and obtains a kind of raw material and is easy to get, and preparation technology is simple, the acrylic powder coating of stable performance, and the used resin of preparation coating.
Above-mentioned purpose realizes by following design: the novel acrylic powder coating that promptly adopts resins of the present invention.What the present invention used is (methyl) acrylate copolymer to fat, and this multipolymer is made of three types monomer, need not add other properties-correcting agent that improves cross-linking density, and three kinds of used monomers are:
1. the general formula of 10--30% (weight) is
Methacrylic ester that contains epoxide group or acrylate, the R in the formula is H or CH
3, as glytidyl methacrylate or acrylic acid epoxy propyl ester.
2. having of 40～70% (weight) logical is
Alkyl acrylate, in the formula: R
1Be H or CH
3, R
2Be the alkyl of carbonatoms 1--18,
As: (methyl) methyl acrylate, (methyl) ethyl propenoate, propyl methacrylate, (methyl) butyl acrylate, (methyl) isobutyl acrylate, (methyl) vinylformic acid 2--ethylhexyl ester etc.
3. the aromatic hydroxy compound that contains vinyl of 10--40% (weight)
As: vinylbenzene, vinyl toluene, ethyl styrene etc.
Details are as follows for technical scheme of the present invention: at first prepare copolymer resin.
Above-mentioned three kinds of polymer monomers are made multipolymer by copolyreaction.The copolymerization process that can take comprises: solution polymerization, letex polymerization, suspension polymerization, mass polymerization, wherein suitable with solution polymerization.Employed solution comprises: toluene, ethylbenzene, dimethylbenzene, benzene, acetone, methylethylketone etc. are wherein suitable with toluene.Polymerization temperature generally is controlled at 105～115 ℃, and the initiator that uses in the polymerization process comprises: peralcohol class and azo-compound class, as: benzoyl peroxide, t-butyl hydrogen peroxide, dicumyl peroxide, azo-bis-isobutyl cyanide etc., its consumption are the 1--5% (weight) of monomer weight.
With the above-mentioned multipolymer that the obtains processing that outgases, remove solvent after, just can obtain powder coating resin.Degas method has the continuous tower degassing, the degassing of batch still formula, but tower degassing operate continuously, and output is bigger, but quality product is difficult to control, equipment requirements strictness; The degassing of still formula, facility investment is bigger, and quality product is easy to control, and is easy to operate, and degassing temperature generally is controlled at 180--210 ℃, and vacuum degree control is in 1.0--1.01 * 10
5During Pa, reach degassing terminal point.The degassing is emitted resin after handling while hot, is cooled to room temperature, obtains faint yellow brittle resin.
The resin that the present invention obtains has following feature: molecular weight is 1000～10000, (the best is 3000～5500); Softening temperature is 80～150 ℃.(the best is 100～110 ℃); Second-order transition temperature is 45～7O ℃ (best 50～65 ℃); Molecular weight distribution is below 2.0, and volatile content is 1～10 ‰. and (weight), (best≤8 ‰), otherwise will influence the storage characteristics of powder coating and the outward appearance of filming.More than national standard method is all adopted in test.
With the above-mentioned resin that makes and a certain proportion of filler, pigment, solidifying agent, flow agent, catalyst mix again through the screw extrusion press shear-mixed, are pulverized, sieve, just can be obtained powder coating of the present invention.
In the powder coating of the present invention, resin content is 30～90% (weight), and the filler that uses in this powder coating has titanium dioxide, light calcium carbonate, and lithopone, talcum powder etc., its consumption are 15--30% (weight)
The pigment that uses in this powder coating is identical with use in the solvent paint, and its consumption is decided according to required colourity.
The solidifying agent that uses in this powder coating is a kind of aliphatic dicarboxylic acid, and as adipic acid, sebacic acid, lauric acid, tetradecyl diacid etc., its consumption is 5～20% (weight).
The flow agent that uses in this powder coating is the polymkeric substance of commercially available vinylformic acid high-carbon ester class, and as the GLP series flow agent that chemistry company limited in the South Sea, Ningbo produces, its consumption is 0.5--0.7% (weight).
The catalyzer that uses in this powder coating is quaternary ammonium salt compound, and as hexadecyl tributyl ammonium chloride, benzyltrimethylammonium bromide, tetrabutyl iodate amine, cetyl trimethylammonium bromide, waiting its consumption is 0.1--0.3% (weight).
The coating of gained of the present invention, its granularity are the 180--200 order, and free flowable powder is sprayed on it through on the parkerized metallic surface, toasts then, and top coat smooth, smooth, the color and luster homogeneous just can obtain filming.Spraying method commonly used has: the friction spraying, and electrostatic spraying, methods such as thermopnore spraying, wherein more suitable with electrostatic spraying.
Powder coating of the present invention, coating mirror luster degree after the spraying is 90--94 (160 ℃), (by (GB1743--79 mensuration), shock strength is 2.94--4.41 Jiao Er (pressing GB1732--79 measures), snappiness 1--2 level (pressing the GB1731--79 test), sticking power 1--2 level (pressing the GB1720--79 test) is more than the pencil hardness 2H.
