Abstract
The present invention provides acrylic precoating primer which is composed of styrene, copolymer resin composed of butyl acrylate and acrylic acid, corrosion resistance pigment of iron oxide and iron oxide black, talcum powder, bentonite and amide modified hydrogenated castor oil. The acrylic precoating primer is diluted to required viscosity by using xylene or toluene as solvent and a diluting agent composed of 30% propanone, 20% butyl acetate and 50% toluene or benzene. The acrylic precoating primer has the advantages of high water resistance, no influence on welding performance, small burning area, rapid dryness, outstanding rust prevention, abrasion resistance, oil resistance, shock resistance, no desquamation after shock and bend, etc.
Description
The present invention relates to a kind of shop primer and synthesis technique thereof, be specifically related to a canned vinylformic acid shop primer and a synthesis technique thereof.
Rust cleaning is the operation before the steel surface japanning, adopts craft, not only dirty but also tired for a long time, and work efficiency is low.Since the eighties, adopted advanced technologies, be that steel plate or steel are before undressed, earlier with from polish streamline with iron rust on the surface and oxide skin through polishing or edges and corners sand removing rust and oxide skin eliminated, automatically spraying dry paint immediately is the rust-inhibiting paint of 15 μ m to 40 μ m thickness, and the lacquer of this type is exactly shop primer or claims shop primer.Its requirement is:
1. the steel plate that scribbles shop primer does not have influence to welding or cutting.
2. can adapt to the requirement of polishing pipelining, generally at 5 minutes inner dryings, before promptly steel plate arrived the streamline terminal, paint film was dried, can pile up.
3. have good rust-preventing characteristic, place the open air, the antirust time limit was not less than 6 months.
4. paint film has good mechanical properties, and wear-resisting wiping, oil resistant, shock-resistant do not come off after the impact bending.
5. can be fit to CO
2The requirement of protection weldering, burn surface area is little, and the gas that produces during welding is no more than the labour protection allowed band.
6. institute's painted kind above from now on there is extensive matching capacity.
Shop primer commonly used both at home and abroad at present mainly is divided into three types promptly:
1. epoxy zinc rich primer;
2. the tetraethoxy zinc powder coats with lacquer;
3. epoxy iron red shop primer.
These three types can be coated with lacquer all is two canned, with preceding mixed, and requires to use up in the regular hour, expired promptly glued, therefore use go up inconvenient.1st, 2 type shop primers, the zincilate amount is big, produces zinc fume during welding, and is unfavorable to HUMAN HEALTH, easily gives birth to " zinc pyreticosis " occupational illness.Therefore, the shop primer of canned not zincilate is a developing direction.
The present both domestic and external one canned zinc shop primer that do not contain, its drying property or rust-preventing characteristic, weldability all has weak point, does not reach the quality level of two canned shop primers, technical indicator.
The object of the present invention is to provide a kind of vinylformic acid shop primer and synthesis technique thereof.
Above-mentioned purpose of the present invention realizes in the following manner: a kind of synthesis technique of vinylformic acid shop primer, comprise that resin is synthetic: the vinylformic acid and the initiator of the butyl acrylate of the vinylbenzene of 38 parts of weight, 10 parts of weight, 2 parts of weight are added in the toluene of 50 parts of weight, in 105-110 ℃ of reaction 5 hours, obtain acrylic resin; The 400 order talcum powder that add the iron oxide black of the red iron oxide of 10 parts of weight, 3 parts of weight, 10 parts of weight then, 0.8 the organobentonite of part weight, 0.3 the ethanol of part weight, 0.2 the modified hydrogenated Viscotrol C of acid amides of part weight, the dilution material that 30%/20%/50% acetone/N-BUTYL ACETATE/toluene of the dimethylbenzene of 18 parts of weight or toluene and 10 parts of weight or benzene are formed, in high speed, mix in the dispersion machine, be milled to below the fineness 50 μ m at the sand mill medium sand again, be adjusted to required viscosity with above-mentioned dilution material again, make after filtering by 100 mesh sieves.
Advantage of the present invention is tangible, because the dried lacquer thickness of shop primer on steel is generally at 15 μ m-20 μ m, adopt Airless spraying to construct, reach this scope, shop primer will add isopyknic thinner, therefore dilutes the traditional lacquer in back, and viscosity is very low, be about about 12 seconds with being coated with 4 glasss of mensuration, can cause two problems thus: the pigment in (1) lacquer easily precipitates; (2) resin in the lacquer is easily separated out, and produces the situation of stopping up spray gun rifle mouth when making spraying; If stifled rifle is arranged, will produce " blank ", promptly steel plate is gone forward and then is coated with lacquer and do not spray at streamline.The present invention has adopted wilkinite and acid amides tart hydrogenated castor oil, and both mix use, and desirable strong point has separately solved the product that pigment is separated out in the lacquer.Ketone was made a kind of component in the mixed solvent in the present invention adopted, and acetone is strong to the resin dissolves ability, even resin is under the situation of Macrodilution, do not separate out yet, it is transparent clear still can to keep, and the acetone volatility is fabulous simultaneously, and the timely drying that guarantees streamline is played a role.If because temperature Change, at temperature height in summer, can adopt toluene in the mixed diluent, can adopt purified petroleum benzin winter, spring and autumn the sky can adopt toluene and purified petroleum benzin and usefulness, produce " doing spray " phenomenon to prevent that summer volatilization is fast, slow in the volatilization in winter, and when making steel plate arrive at the streamline terminal, also do not parch and can not pile up.Simultaneously, increase the vinylbenzene composition in the resin among the present invention water tolerance is increased, and burn surface area is also little during welding.Therefore, the present invention has fully satisfied the requirement of shop primer to the key technical indexes such as mechanical property of water-fast, anti-welding and excellence.
Below, with the present invention is described in further detail in conjunction with specific embodiments.
Embodiment:
Vinylbenzene with 38 parts of weight, the butyl acrylate of 10 parts of weight, the initiator benzoyl peroxide of the vinylformic acid of 2 parts of weight and 0.5 part of weight mixes in mixer, be added dropwise to then in the polymerization pot of the toluene that 50 parts of weight are housed, dripped 3 hours 100 ℃ temperature, again 110 ℃ of insulations 3 hours, be cooled to sieve below 60 ℃ after, the acrylic resin that obtains, again it is joined in the stirring tank, the red iron oxide that adds 10 parts of weight simultaneously, the iron oxide black of 3 parts of weight, 400 purpose talcum powder of 10 parts of weight, 0.8 the organobentonite of part weight, 0.3 the ethanol of part weight, 0.2 the hydrogenated castor oil of the acid amides modification of part weight, the dimethylbenzene of 18 parts of weight (or toluene); And the dilution material formed of the toluene (or benzene) by 30% acetone, 20% acetate butyl and 50% weight of 10 parts of weight, use after mixing under high-speed stirring in the pump suction sand mill, sand milling is below the 50 μ m, then to fineness again, pump in the paint still, use above-mentioned acetone: acetate butyl; Toluene (or benzene) is that 30: 20: 50 thinner is diluted to viscosity in indication range, after sieving, and packing.
The specification of resin is in the foregoing description: 1. solids content 〉=48%; 2. viscosity (being coated with-4 glasss, 25 ℃) 300-500 second; 3. water tolerance (resin is applied on the tinplate and did after 24 hours immersion 24 hours) non-whitening; 4. to the dilution of solvent: after releasing with the above-mentioned thinner alkene of duple, form clear lacquer liquid.
Last art embodiment only for illustrative purposes, protection domain of the present invention will embody in claims.
