Description
Technical Field
The invention relates to a steel structure water-based anticorrosive paint and a preparation method thereof, belonging to the technical field of paint corrosion prevention.
Background
Anticorrosive coatings are generally divided into conventional anticorrosive coatings and heavy anticorrosive coatings, and are an essential coating in paint coatings. The conventional anticorrosive paint plays a role in corrosion resistance on metals and the like under general conditions, and protects the service life of nonferrous metals; the heavy-duty anticorrosive coating is an anticorrosive coating which can be applied in a relatively severe corrosive environment compared with a conventional anticorrosive coating and has a longer protection period than the conventional anticorrosive coating.
Chinese patent CN 103820012 a discloses an anticorrosive paint, its preparation method and an oil pipe with anticorrosive paint on the surface: the corrosion inhibitor is prepared from a film forming substance, an organic corrosion inhibitor, an antirust additive and an organic solvent. The invention has the performances of corrosion resistance, water resistance, acid resistance and alkali resistance which meet the standard requirements, but the organic solvent can not meet the environmental protection requirement at the present stage, and meanwhile, the durability of the corrosion resistance is slightly poor.
Chinese patent CN 107603407A discloses a special water-based anticorrosive paint for steel surfaces: firstly stirring and mixing chitosan and water, standing and swelling, then dropwise adding tetrabutyl titanate, then adding chitosan enzyme for hydrolysis, then adding a curing agent for stirring and mixing, then adding waterborne epoxy resin, water, a defoaming agent, a thickening agent and pigment and filler for continuous stirring, and obtaining the special waterborne anticorrosive paint for steel. The anti-rust pigment is obtained by hydrolyzing chitosan, has the advantages of low cost, environmental protection and the like, but has complex process and poor anti-corrosion performance compared with the anti-rust pigment. If the anti-corrosion performance cannot meet the standard due to incomplete hydrolysis of the chitosan, impurities are remained in the coating, and the anti-corrosion performance is greatly reduced.
Disclosure of Invention
The purpose of the invention is as follows: aiming at the problem of insufficient performance of the traditional anticorrosive paint on a steel structure, the steel structure water-based anticorrosive paint with better anticorrosive performance and low cost is provided.
The technical scheme is as follows: the water-based anticorrosive paint for the steel structure is characterized in that: the composition is prepared from the following components in parts by weight: epoxy resin: 27-40 parts; polyester: 2-3 parts of a solvent; modified graphene: 1-2 parts; solvent: 4-7 parts; deionized water: 50-72 parts; auxiliary agent: 1-5 parts; antirust pigment: 10-20 parts; filling: 10-20 parts.
The invention further defines the technical scheme as follows: the epoxy resin is bisphenol A epoxy resin E-20 or E-12.
Preferably, the polyester is a polycaprolactone polyol or a polycarbonate diol.
Preferably, the solvent is propylene glycol methyl ether or ethylene glycol butyl ether.
Preferably, the auxiliaries include dispersants, wetting agents, flash rust inhibitors, and defoamers.
Preferably, the rust-preventive pigment is zinc phosphate or aluminum tripolyphosphate.
Preferably, the filler comprises at least one of talc, mica powder and precipitated barium sulfate.
The invention also discloses a preparation method of the steel structure water-based anticorrosive paint, which is characterized by comprising the following steps of:
step 1, heating 2-4 parts by weight of epoxy resin and 2-3 parts by weight of polyester to 100-120 ℃ to completely melt the epoxy resin and the polyester;
step 2, cooling to 80-90 ℃, adding 1-2 parts by weight of modified graphene, and stirring for reaction for 3-4 hours;
step 3, after the reaction is finished, cooling to 50-60 ℃, adding 4-7 parts by weight of solvent for dilution, and continuously stirring for 0.5-1 h;
step 4, after stirring, adding 25-36 parts by weight of molten epoxy resin, uniformly stirring, and slowly dropwise adding a mixture of 30-42 parts by weight of deionized water and 1-5 parts by weight of an auxiliary agent;
and 5, after the dropwise addition is finished, increasing the stirring speed, adding a mixture of 10-20 parts by weight of antirust pigment, 10-20 parts by weight of filler and 20-30 parts by weight of deionized water, and continuously stirring for 2-3 hours to obtain the antirust pigment.
Preferably, the stirring speed in the step 5 is 700-1000 r/min.
Has the advantages that: compared with the prior art, the modified graphene is grafted into the long-chain section of the high polymer by a chemical method, and other components are added into the anticorrosive paint by a physical mixing method to prepare the steel structure water-based anticorrosive paint. The antirust pigment of zinc phosphate or aluminum tripolyphosphate is added to inhibit the anodic reaction because of forming a complex precipitate with ferric ions on the metal surface, and can also form a complex with hydroxyl, carboxyl and the like in a film forming substance and a curing agent, and can also perform electrochemical reaction with air and moisture between the paint and a base material, so that the reactions such as chemical reaction and the like are inhibited, and the anticorrosion effect is obtained. Due to the fact that the graphene has the properties of super large specific surface area, excellent barrier property, high chemical stability, good conductivity and the like, the corrosion resistance of the water-based anticorrosive paint can be effectively improved. The combination of the two can effectively improve the corrosion resistance of the water-based anticorrosive paint. The steel structure water-based anticorrosive paint disclosed by the invention has the acid resistance, alkali resistance and salt spray resistance far exceeding the requirements of the standard HGH 4759-2014.
