Description
Technical field
The present invention relates to a kind of preparation method of coating.
Background technology
For some base material, when its exposed outside time, because being subject to the matter corrodes in air, base material is easy to cure, thus affects the mechanics of base material, heat-resisting, weather-proof, wear-resisting and corrosion resistance nature etc.For this technical problem, a lot of people is had now to study the sulfuration how reduced base material.Wherein mode is a sprayed coating on base material, as at application number be 200610078245.1 patent documentation in disclose a kind of sulfuration resistant coating, although have now a lot of people at the coating of research in this, at present the sulfur resistive voltinism of coating need to improve.
Summary of the invention
In order to prepare the coating that can improve sulfuration resistant performance, the invention provides a kind of preparation method of coating.
For achieving the above object, a kind of preparation method of coating, counts by weight, comprises the steps:
(1) take 10-15 part film coalescence aid, 10-20 part magnesium oxide, 12-22 part silicon oxide, 1-2 part ferric oxide, 5-8 part toluenesulphonic acids, 5-8 part calcium carbonate, 2-3 part suspension agent, 3-5 part alcoholic solvent, 1-2 part caking agent and 20-30 part deionized water to stir under the rotating speed of the temperature 400 ~ 800r/min of 60-70 DEG C;
(2) taken 50-60 part zinc acrylate resin to join in step (1), and reacted 25-35min while stirring in the water-bath of 90-110 DEG C;
(3) take 0.7-1.2 part thickening material, 0.5-1 part defoamer, 0.4-0.8 part flow agent join in step (2), under 200 ~ 400r/min speed conditions, stir 10 ~ 13 minutes; Obtain coating after filtration.
Further, described film coalescence aid is butyl glycol ether.
Further, described suspension agent is lithium bentonite.
Further, resol and the rosin of described caking agent to be ratio of weight and number be 3:1.
Further, described thickening material is polyvinyl butyral.
Further, described defoamer is broken bubble polysiloxane solution.
Further, described flow agent is terminal groups modification organosilicon.
The invention has the beneficial effects as follows: coating is sprayed onto after on base material, when the sulphur in air touches paint film, under the effect of toluenesulphonic acids, the reaction product generated after zinc acrylate resin, magnesium oxide and sulfurous gas react remains in coating, prevents sulfurous gas directly to contact with substrate interface.Be suspension agent with lithium bentonite, this wilkinite is for raw material with natural calcium base bentonite, through a kind of mineral material that artificial lithiumation modification is prepared, it can form colloidal material with alcoholic solvent under the initiation of deionized water, the expansion thickening ability obtained, resol and rosin is selected to make binding agent, resol normal temperature cohesive force is strong, coating can be made to obtain high normal temperature surface intensity, but gas forming amount is larger, when the large coating of add-on is lighted easy to crack and easily cause base material produce gas hole defect, rosin is not easy to crack after coating is lighted.Therefore, adopt resol and a small amount of rosin with the use of, not only can reduce the add-on of binding agent, the cohesive strength of raising coating, and carrier viscosity can be improved, make its sulfur resistance better.
