Abstract
The invention provides an epoxy resin anticorrosion paint comprising catechol. The paint is prepared from the raw materials of, by weight: 55-60 parts of E-44 epoxy resin, 9-12 parts of 3-diethylaminopropylamine, 5-9 parts of sodium-based bentonite, 1-2 parts of soda ash, 12-14 parts of dimethyl formamide, 2-3 parts of catechol, 6-8 parts of styrene, 1-2 parts of an antioxidant 1010, 15-18 parts of xylene, 9-12 parts of butyl acetate, and 4-5 parts of film-forming resin. The raw materials are non-toxic and environment-friendly, such that low toxicity to human body is caused during production and application processes. Also, environment pollution is low. The film-forming additive is added in the formula, such that compatibility among the components is improved, and a film-forming effect is greatly improved. An obtained paint film has excellent water resistance and corrosion resistance. The bonding strength is high. The paint film is alkaline resistant, and has good water resistance.
Description
Technical field
The present invention relates to metal rust preventing technical field, be specifically related to a kind of anti-corrosive paint of epoxy resin that contains catechol and preparation method thereof.
Background technology
Metallic corrosion is the very serious problem that people face.The metal that scrap because of metallic corrosion every year in the whole world reaches more than several hundred million tons, and financial loss accounts for 1.5%～2.5% of total value of production in national economy.Metal rusting is the most general, loss is maximum a kind of corrosion.Antirust work is always one of great scientific research task both domestic and external, and people work out the corrosion that many kinds of measures prevented and suppressed metal, and antirust with coating is a kind of effective means.
Summary of the invention
The object of this invention is to provide a kind of anti-corrosive paint of epoxy resin that contains catechol and preparation method thereof, various metals is had to antirust function.
Technical scheme of the present invention is as follows:
An anti-corrosive paint of epoxy resin that contains catechol, is characterized in that, its feed composition by following weight part is prepared from:
E-44 epoxy resin 55-60,3 diethyl aminopropylamine 9-12, sodium bentonite 5-9, soda ash 1-2, dimethyl formamide 12-14, catechol 2-3, vinylbenzene 6-8, antioxidant 1010 1-2, dimethylbenzene 15-18, N-BUTYL ACETATE 9-12, film-forming resin 4-5.
The described anti-corrosive paint of epoxy resin that contains catechol, is characterized in that: described film coalescence aid is prepared from by the raw material of following weight part:
Alcohol ester 12 15-18, methylethyl ketone peroxide 1-2, silane resin acceptor kh-550 1-1.3,2-hydroxypropyl acrylate 2-3, lapis amiridis 1-1.4, tea-polyphenol 1-2, polyisobutene 1-1.4, ethyl acetate 12-14, wintergreen oil 1-2;
Preparation method mixes 2-hydroxypropyl acrylate, lapis amiridis, tea-polyphenol, polyisobutene, ethyl acetate, add methylethyl ketone peroxide, stirring reaction 45-60 minute, then, is warming up to 70-80 ℃, add Silane coupling agent KH550, alcohol ester 12, continue stirring reaction 60-90 minute, then, add other remaining component, stir 30-40 minute, with 500 order filter-cloth filterings and get final product.
The preparation method of the described anti-corrosive paint of epoxy resin that contains catechol, is characterized in that, comprises the following steps:
(1) first dimethylbenzene and N-BUTYL ACETATE being joined to reactor mixes;
(2) then in solvent, add successively E-44 epoxy resin, 3 diethyl aminopropylamine, vinylbenzene, oxidation inhibitor, under room temperature, first the speed with 300-400r/min stirs 8-10 minute, and then stirs 10-15 minute with the speed of 800-1000r/min, then the rest materials in formula is all joined in still, speed high speed dispersion 20-30 minute with 1200-1400r/min, then scattered mixture is dropped in sand mill and is ground, then filter with 300 order filter cloths.
Beneficial effect of the present invention:
Advantages of nontoxic raw materials of the present invention, and environmental friendliness, therefore production and use procedure are little to human body murder by poisoning, and environmental pollution is low, adds film coalescence aid in formula, has improved the consistency of each composition, has greatly improved film-formation result.The paint film of gained is water-fast, antiseptic property is excellent, and bonding strength is firm, alkaline-resisting, water tolerance is all good.
