The preparation method of described aqueous asphalt imitation anticorrosion coating for container chassis: imitate bitumastic formation weight percentages of components according to described water-based and take each component respectively, and prepare with processing condition as follows:
(1) under agitation, add the tap water in formula, wetting dispersing agent A, wetting dispersing agent B, pH adjusting agent, anti-sudden strain of a muscle rust agent, and add defoamer weight in formula 20-30%, stir; Under 800-1200r/min rotating speed stirs, add the anti-settling agent in formula, iron oxide black, then dispersed with stirring is until fineness arrives less than 65 μm, under agitation, add the 20-30% of defoamer weight in formula, stir froth breaking 3-5min, be i.e. obtained pigment slurry;
(2) under agitation, described pigment slurry is joined in the aqueous acrylic emulsion in formula, add the talcum powder in formula, barium sulfate, zinc phosphate, aluminium triphosphate, salt spray resistance auxiliary agent again, 15-30min is stirred under 800-1500r/min rotating speed, add remaining film coalescence aid, thickening material in formula, stir, place slaking 30-60min, obtain aqueous asphalt imitation anticorrosion coating for container chassis.
Preferably, the agitation condition in described step (1) and step (2) refers to that rotating speed is the stirring of 100-600r/min.Described dispersed with stirring is until it is under rotating speed is 1800-3000r/min that fineness arrives less than 65 μm, and high speed dispersion 20-30min realizes.
Water-based of the present invention imitates the mixing of pitch anticorrosive coating and grinding plant is common equipment in dope preparing process, comprises high speed dispersor, sand mill, ball mill etc.
Due to the bonding force depending on Anticorrosion Construction quality, particularly coatings and substrate work-ing life to a great extent of metal, closely related with the surface treatment quality of container.In derusting, coat-thickness and execution conditions factors, derusting is to whole coating quality and pipeline, the having the greatest impact of container work-ing life.It is generally acknowledged that surface treatment quality accounts for 50% of whole influence factor, coat-thickness accounts for 19%, and coating type accounts for 5%, and construction environment accounts for 26%.Long term production proves, derusting good than derusting difference or long 3 ~ 5 times without the work-ing life of the coating of processing of rust removing.Before construction, preferably carry out derusting by sandblast to construction surface, derusting grade reaches the Sa2.5 level that GB/T 8923 specifies.Then the water-based of preparation is imitated pitch anticorrosion base coat, finish paint each brush 1 road, altogether twice, control thickness well.
The present invention compared with prior art tool has the following advantages:
1) product of gained of the present invention belongs to a kind of environment-friendly type aqueous imitative pitch anticorrosive coating.Be characterized in: use high performance novel antirust pigment, it has nontoxic, pollution-free, high rust resistance, lower-price characteristic, paint film shows through long-term soak test, coating is unchanged under the conditions such as 5% sulfuric acid, 5% sodium hydroxide, NaCl salt solution, salt fog, shows good erosion resistance.
2) construction of the product of gained of the present invention is simple and convenient, can directly use water as thinner, at processed steel surface direct spraying.
3) technological process of production of the product of gained of the present invention is basically identical with the technological process of production of conventional anticorrosive coating, and major equipment used and starting material all commercially can be bought and obtain, and are easy to realize scale operation.
