Abstract
An antirust insulating paint is prepared from water acrylic resin, solid inorganic filler and water-soluble solidifying agent in mass ratio of 100:(40-120):(15-45). Its advantages include no poison, high water-proof and antirust performance, and high volume resistance (greater than 1000 ohm/micron).
Description
The present invention relates to propylene ester resin, specifically antirust, the insulation compound of aqueous acrylamide ester resin.
Up to the present, the technology of formation one layer insulating and the prescription of coating have had many on the conduction steel disc.Coating the earliest mainly is that chromic salt and phosphoric acid salt form one deck mineral membrane on the conduction steel disc.Although the excellent heat resistance of mineral membrane, its water tolerance, shock resistance, tack are all very poor.Recently, in order to address the above problem, there has been certain methods to use the compo prescription that comprises organic and inorganic two main ingredients.This prescription has made full use of good water-fast, the insulation of good welding property of mineral membrane and resistance toheat and organic membrane, shock resistance and adhesion property.For example U.S. Pat 4,830, and 877, US4,844,753, US5,624,749, mentionedly in the Chinese patent 98,125,437 be used for the coated with conductive steel disc to form the coating of insulation layer, all be to adopt this class organic one inorganic compo prescription.
US4,844,753 have proposed a kind of method that forms one deck insulating film on electromagnetic steel sheet.Mainly comprise acrylic resin, guanamine resin, chromic salt, emulsifying agent and dispersion agent in the prescription, form antiknock permeability good insulation coating.But its curing speed is slower, wants three minutes film-formings under 300 ℃, can influence production efficiency, and uses harmful chromic salt.
US4, the formulation for coating material of insulating coating mainly comprises (methyl) acrylic resin that contains unsaturated carboxylic acid on 830, the 877 conduction steel discs that propose, and adopts Powdered methyl methacrylate to improve the welding property of coating.But the inorganic component of this prescription contains deleterious chromic salt, and preparation technology is complicated.
US5,624,749 utilize emulsion polymerisation process to prepare hud typed emulsion, examine to be crosslinked hydrophobic resin, and shell is a hydrophilic resin, and the insulating film that makes has the good comprehensive performance.But preparation technology is complicated, will certainly improve the production cost of factory.And used a large amount of tensio-active agents in the preparation process, and make coating in use spume because stir easily, defectives such as aperture appear in the final film surface that makes, thereby have reduced the insulativity and the erosion resistance of film.And the adding of tensio-active agent also can reduce the stability and the anti-freezing property of coating.
Chinese patent 98,125,437 mentioned coating have used commercial acid acrylic resin to prepare this type of coating, mainly improved the water absorbing properties of coating, make coating in the atmospheric environment of humidity, be difficult for being clamminess, there are harm and disabled pure ethers organic solvent in the Human Physiology system but used in the process for preparation of coating.
The purpose of this invention is to provide a kind of on electromagnetic steel sheet, form the superior isolation coating, need not poisonous organic solvent and the water-borne acrylic resin coating of chromic salt.Another object of the present invention provides the method for making of coating of the present invention.
Technical scheme of the present invention is as follows:
Antirust, the insulation compound of a kind of water-borne acrylic resin, it mainly is made up of water-borne acrylic resin, inoganic solids filler and water soluble solid agent, the mass ratio of water-borne acrylic resin and inoganic solids filler is 100: 40-120, water soluble solid agent consumption is the 15-45% of resin quality, and wherein water-borne acrylic resin is mainly formed by following three kinds or four kinds of monomer polymerizations:
A. alkyl acrylate or alkyl methacrylate, wherein alkyl is the alkyl of 1-4 carbon atom,
B. vinylformic acid hydroxyalkyl acrylate or methacrylic ester hydroxyalkyl acrylate, wherein hydroxyalkyl is hydroxyethyl or hydroxypropyl,
C. the organic carboxyl acid that contains unsaturated double-bond,
D. add or be not added with vinyl monomer, wherein the mass ratio of A, D component sum and B, C component sum is 20-40: 80-60, and the water-borne acrylic resin of gained after the polymerization is neutralized into water dispersion with the aqueous solution of organic bases.
Inoganic solids filler in the above-mentioned coating can be phosphoric acid salt, silicate or carbonate or the titanium dioxide of calcium, zinc or aluminium, or their mixture, and their median size is 0.1-0.5 μ m, and through the organo-silicon coupling agent surface activation process.The median size of water-borne acrylic resin water dispersion is 0.1-0.4 μ m.The mass ratio of acrylic resin and water is 100: 40-60.
Vinyl monomer can be vinyl cyanide, vinylbenzene or iso-butylene in the monomer of the water-borne acrylic resin of above-mentioned coating.
In the above-mentioned coating, the organic bases of neutralization usefulness is a boiling point at 100-200 ℃ organic amine, as triethylamine, dimethylethanolamine or diamino dimethyl propyl alcohol.
Water-borne acrylic resin of the present invention is antirust, the method for making of insulation compound, and it mainly comprises the following steps:
A. with 30-45 part (quality, down with) alcoholic solvent places reactor, is warming up to 80-90 ℃, stir 25-35 part that property adding next time is dissolved with the oil soluble radical initiator and contain above-mentioned A, B, four kinds of monomeric mix monomers of C, D, be incubated 30-60 minute, slowly splash into above-mentioned mix monomer 75-65 part that is dissolved with initiator again, dropwise, be incubated 40-60 minute, measure double bond content, guarantee that monomer conversion greater than 97% back cooling, adds organic bases and is neutralized to PH6-8
B. the water-borne acrylic resin that steps A is made adds solidifying agent and mineral filler, and thin up is 30-80 second (method by GB1723-79 is measured with coating-4 viscosity meter) to viscosity.Ball milling or sand milling mix coating, promptly get antirust, the insulation compound of water-borne acrylic resin of the present invention.
Coating of the present invention is with 1-4 gram/m
2The consumption roller coat on treated steel disc, 300-500 ℃ the oven dry film forming.This paint solidification speed is fast, and at 300 ℃, 1 minute is completion of cure.
Water-borne acrylic resin of the present invention is antirust, insulation compound does not contain poisonous organic solvent and chromic salt, and sticking power reaches one-level, and volume resistance is greater than 1000 ohm every micron, water-fast, good antirust property.
