The rare-earth organic ceramic paint is characterized by consisting of the following compositions in percentage by weight: 3 to 15 percent of epoxy resin, 3 to 10 percent of phenolic resin, 1 to 5 percent of firming agent, 1 to 5 percent of synthetic rare-earth additive, 0.3 to 1 percent of flatting agent and 60 to 95 percent of ceramic powdery paint. The process comprises the following steps: firstly, resin is modified in a reaction kettle; the temperature is controlled to between 100 and 120 DEG C; secondly, a sheet ceramic powdery body and the modified resin are mixed in a high-energy mill and grinded for 60 to 100 minutes; and finally, other compositions in a formula are mixed, dispersed, filtered and canned. The rare-earth organic ceramic paint has good wearing resistance, corrosion resistance and insulation and is an environment-friendly, multifunctional and excellent heavy anticorrosive paint which has hardness more than 8H, improves the wearproof performance, shortens the curing time and improves the curing degree, thereby prolonging the service life of an object protected by the paint and reducing the use cost of the product.
Description
One, technical field
The present invention relates to a kind of rare earth organic ceramic coating and manufacture method thereof, belong to paint field.
Two, background technology
Protective system mainly is made up of base-material, filler and auxiliary agent, and base-material generally uses Resins, epoxy, urethane resin etc., but the performance difference of resin is very big, and the auxiliary agent aspect often contains the component of heavy metal.Filler is being brought into play important effect in coating system, because the anti-corrosion dominant mechanism of coating is still seeing through of the mask erosion factor, therefore heavy anticorrosion protective system filler has adopted sheet or ball filler, as glass flake, iron mica scale etc., but because its powder size is bigger, often its performance still can not meet the demands.
In recent years, the research to surface side filler abroad develops towards super-refinement and nanotechnology aspect to a great extent, present Japanese river Inland Steel development of metallic powder filler is thick to be 100～500nm, Canadian Canbro company has also developed this type of coating, and develops towards the direction of high-solid level, multifunctional anticorrosive coating.
In the research of China with produce seldom, various zinc-rich paint, glass-flake coating account for very big proportion on the anticorrosive coating kind of better performances, and the coating of superfine sheet filler and ultra-fine anti-corrosion powder filler does not almost have.In general, the solids constituent of these coating is about 50%, and a lot of organic solvent of volatilization during use, and contain heavy metals such as Pb, Cr does not have the feature of environmental protection.Simultaneously only have single antiseptic property, and performance is not high, does not have good wear resistance and hardness (1H～3H).In addition, these execution of coating performances and drying property are relatively poor, and coating lumps easily, be difficult for to use, should not thick being coated with, and time of drying is long, and operating efficiency is low.
Three, summary of the invention
The object of the present invention is to provide and a kind ofly make the dispersion of coating more stable, make the ceramic powder refinement simultaneously and separate fully and coat, and can improve anti-acid-basicity, non-corrosibility, wear resistance, impact and high-insulativity and the feature of environmental protection of coating greatly, improved hardness of film effectively, removed the heavy metal in the coating, it is strong attached power, has fabulous oil-proofness, normal temperature self-drying, rare earth organic ceramic coating that rate of drying is fast and manufacture method thereof.
Technical solution:
The present invention is made up of the weight percent of following component: Resins, epoxy 3%～15%, resol 3%～10%, solidifying agent cashew nut plant shell press oil 1%～5%, synthesizing rare-earth auxiliary agent 1%～5%, flow agent 0.3%～1%, ceramic powder pigment 60%～80%, cellosolve 1%～3%, thinner 5%～10%.
Ceramic powder pigment is one or more in aluminum oxide, titanium oxide, silicon oxide, ferric oxide, the chromic oxide.
Solidifying agent be the cashew nut plant shell press oil, polymeric amide or polyamine.
The synthesizing rare-earth auxiliary agent is C7～C9 acid synthetic monocarboxylic acid rare earth cerium salt.
Cellosolve is the mixture of mibk and dimethylbenzene.
Flow agent is the polyacrylic ester copolymerization.
Thinner is a cresylglycidylether.
The manufacturing process of rare earth organic ceramic coating, earlier with Resins, epoxy, resol 65 ℃～70 ℃ of stirring heating in reactor, kept 30 minutes, temperature rises to 95 ℃～102 ℃, hold-time is 30 minutes, be cooled to 50 ℃～60 ℃, add cellosolve, then in high-energy mill with flaky ceramic alumina, Resins, epoxy after titanium oxide powder and the modification mixes, ground 60～100 minutes, mesh-of-grind to 10～15 μ m is sneaked into the ceramic powder pigment of rare-earth additive and hollow ceramic powder pigment and hollow ceramic powder pigment or hollow ceramic powder pigment and heavy at last and is disperseed, filter, canned.
The present invention has adopted several ceramic powders of different different shapeies and proportion to improve anti-soda acid, Corrosion Protection, the wear resisting property of coating greatly.Adopted several resins and extraordinary solidifying agent to make the solids constituent of coating bring up to 90%, and the hardness of filming is improved, the adding of synthesizing rare-earth auxiliary agent, replaced traditional naphthenate, contain heavy metal in the naphthenate, the heavy metal of coating has been removed in the use of compound rare-earth siccative, so rare-earth ceramic coating is the product of environmental protection.Wear resistance and impact property, especially drying property that the use of compound rare-earth auxiliary agent is also collaborative to have improved ceramic coating than common epoxy coating rate of drying soon near 2 times.So this coating belongs to environmental protection, multi-functional, excellent heavy-duty coating.
Making aspect the production technique, adopting resin modification and mix the processing mode of high-energy ball milling simultaneously in reactor earlier, making the dispersion of coating more stable, making the ceramic powder refinement simultaneously and separate fully to coat with filler.Overcome the deficiency of the not enough and easy reunion sedimentation caking of the coating to ceramics powder in the existing coating producing process, improved execution of coating performance normal temperature self-drying, rate of drying is fast, but also oven drying at low temperature of paint film; Paint film is hard: reach 8H～9H, the tool excellent abrasion resistance; Strong adhesion: cross cut test is not less than 2 grades (15～20 μ m); Has extraordinary erosion resistance; Fabulous oil-proofness: be soaked in the extraordinary hydraulic efficiency oil 13 days, coating does not have the hardness ruckbildung, and coatingsurface does not have efflorescence or other slight sign that changes; High-insulativity; The feature of environmental protection.The organic ceramic coating performance index see Table 1.
