Description
Technical field
The present invention relates to a kind of electrophoretic coating high glaze acrylic resins, belong to technical field of coatings.
Background technology
Electrophoresis is one of coating metal workpiece most efficient method.Electrophoretic coating is a kind of novel low stain, save the energy,
Resource-saving and the good coating of anticorrosive property, it has a smooth coating, water resistance and the good advantage of chemical-resistance, and easy to implement
The mechanization and automation of application industry, it is suitable complex-shaped, there are edge corner angle, hole Workpiece coating, is widely used in vapour
The application of the handwares such as vehicle, automatic vehicle, electromechanics, household electrical appliances.
With the continuous development of electrophoretic coating, market proposes its glossiness, stability etc. more next using more and more
Higher requirement.Existing electrophoretic coating is usually added into blast substance to reach highlighted requirement, improves its gloss, light
Damp degree can reach low light（60 degree of glossometers are measured more than or equal to 60 degree）, but its stability is poor, storage in 3-5 months will go out
Existing lamination, and use rear paint film out-of-flatness, fineless and smooth.Develop the electrophoretic coating high glaze propylene of novel high stability
Acid resin becomes a research direction.
Invention content
The technical problem to be solved by the present invention is to provide a kind of high stability electrophoretic coating use for the above-mentioned prior art

The number-average molecular weight of the makrolon is 5000-1 ten thousand；
The composite initiator is both azo-bis-isobutyl cyanide and DCP (cumyl peroxide) according to 1:The mass ratio of 2-5 into
Row is compound.Using DCP as initiator, side chain reaction can be increased, increase the adhesive force and corrosion resistance of coating, especially
Resistance sexuality is significantly enhanced；The conversion ratio of monomer, the compatibility of the two can be promoted to realize using azo-bis-isobutyl cyanide
Low temperature causes, high temperature sustained response.Due to that can discharge thermal energy in reaction process, the temperature of system can rise and occur larger
Fluctuation, in order to ensure reaction is not acted upon by temperature changes, the DCP initiators of introducing mainly ensure to stablize reaction under high temperature,
Ensure that high/low temperature is reacted.
Neutralizer is triethanolamine, methyl diethanolamine or triethylamine.
The preparation method of above-mentioned electrophoretic coating high glaze acrylic resin：
Step 1: configuration mixed solution

Hydroxyl ethyl ester, acrylic acid 2- hydroxyl ethyl esters, acrylic acid 2- hydroxypropyl acrylates, makrolon, dinonylnaphthalene sulfonic acid are mixed to form mixed solution；
Step 2: water soluble acrylic resin is molded
It using n-butanol, isopropanol and accounts for the deionized water of 5%-15% of ion water inventory in reaction vessel and is warming up to as bottom material
95-105 DEG C, compound draw is added dropwise in the mixed solution made of a dropping step one into reaction vessel, time for adding 150-200min
Agent is sent out, composite initiator controls rate of addition by four dropwise additions, according to reaction severe degree；Then reaction vessel keeps the temperature 150-
280min, then reaction vessel be cooled to 60 DEG C and stirred evenly hereinafter, neutralizer is added into reaction vessel, then to reaction vessel
Middle addition antifoaming agent, finally plus the dilution of remaining deionized water is molded.
Compared with the prior art, the advantages of the present invention are as follows：
The present invention is hydrophobic using dinonylnaphthalene sulfonic acid progress, and the makrolon for being subject to a small amount of low molecular weight improves gloss, while big
It is big to reduce carboxylic monomer dosage, increase the dosage of acrylic acid and initiator so that final electrophoretic coating glossiness obtained is high（60
It spends glossometer detection and is more than or equal to 75 degree）, storage 1 year or more, no lamination, stability is good；And paint film flatness is good, resists
Pollution capacity is strong.In reaction process, four dropwise additions of composite initiator part are reacted with complete and safely controllable.

By methacrylic acid isooctyl, n-butyl acrylate, methyl methacrylate, styrene, acrylic acid, methacrylic acid 2-
Hydroxyl ethyl ester, acrylic acid 2- hydroxyl ethyl esters, acrylic acid 2- hydroxypropyl acrylates, makrolon, dinonylnaphthalene sulfonic acid are mixed to form mixed solution；
Step 2: water soluble acrylic resin is molded
It using n-butanol, isopropanol and accounts for the deionized water of 5%-15% of ion water inventory in reaction vessel and is warming up to as bottom material
95-105 DEG C, compound draw is added dropwise in the mixed solution made of a dropping step one into reaction vessel, time for adding 150-200min
Send out agent；Then reaction vessel keeps the temperature 150-280min, during then reaction vessel is cooled to 60 DEG C hereinafter, being added into reaction vessel
It is stirred evenly with agent, then antifoaming agent is added into reaction vessel, finally plus the dilution of remaining deionized water is molded.
5. the electrophoretic coating according to claim 4 preparation method of high glaze acrylic resin, it is characterised in that：It is described
Composite initiator controls rate of addition by four dropwise additions, according to reaction severe degree.
