Description

A kind of water-borne acrylic resin anticorrosive paint and preparation method thereof
Technical field
The present invention relates to a kind of water-borne acrylic resin anticorrosive paint and preparation method thereof, belong to technical field of coatings.
Background technology
The research of acrylic monomers and resin starts from 1805 the earliest, but owing to condition limits, until nineteen twenty-seven just by Rohm & Haas company industrialized production, real application on coating is then after nineteen fifty-three.Acrylic resin paint Today of development.It has been the class synthetic resin coating that type is most, combination property is the most complete, versatility is the strongest, high with other Molecule resin-phase ratio, acrylic resin paint has many prominent advantages, and such as fast light, the weatherability of its excellence, be exposed to the sun in open air Durability is strong, and ultraviolet light irradiates and is not easily decomposed and turns yellow, and can keep original gloss and color and luster for a long time, heat-resist；Corrosion resistant Erosion, has the chemicals such as preferable acid and alkali resistance, salt, oils and fats, detergent to stain and corrosive nature.Acrylic resin paint is existing excellent Decoration performance more, has again good protective value.Both can be made into solvent based coating, and can be made into again water paint, may also be fabricated which No-solvent type coating.Therefore, acrylic resin paint has become a big class coating of greatest concern, that hidden by green grass or young crops.
It addition, along with the development of coatings industry, a new problem is paid close attention to by people day by day, and i.e. organic coating is to environment Pollution problem.In coatings industry, often containing VOC (VOC) in solvent used and auxiliary agent, they are waved It is dealt in air and can cause air pollution.In addition, the poisonous and harmful substance such as hazardous air pollutants (HAPs), heavy metal is also Environmental and human health impacts is worked the mischief.Every coating using water as solvent or making disperse medium, all can be described as water paint. Water paint includes water soluble paint, water-reducible coating, water-dispersible paint (latex paint) 3 kinds.Water soluble paint be with Water-soluble resin is film forming matter, with polyvinyl alcohol and various modifier thereof as representative, and the most water-soluble alkyd resin, water Molten epoxy resin and inorganic polymer resin etc..Its advantage includes: 1. water paint is with water as solvent, saves ample resources； Fire risk when water paint eliminates construction；Reduce atmospheric pollution；Water paint is only with a small amount of hypotoxicity alcohol ether Class organic solvent, improves operating environmental condition.General water paint organic solvent (accounting for coating) between 10%～15%, And present cathode electrophoresis dope is reduced to less than 1.2%, to reducing, pollution saving resource impact is notable.2. water paint is wet Surface and wet environment can directly coat construction；Water paint is good to material surface adaptability, and coating adhesion is strong.3. water Property paint spraying instrument can wash by water, and greatly reduces the consumption of cleaning solvent.4. water paint electrophoresis film is uniform, smooth. Flattening is good；Certain thickness film can be coated in inner chamber, weld seam, corner angle, seamed edge position, have good protective；Electrophoresis is coated with Film has best corrosion resistance, the salt fog resistance of thick film cathode electrophoresis coating to reach as high as 1200h.
CN104673059A discloses a kind of water-based epoxy acrylic resin anticorrosive paint and preparation method thereof, according to weight Percentages, including following raw material components: epoxy acrylic resin 27～37%；White carbon black 2～3%；Blanc fixe 17～ 27%；Rust resisting pigment 5～13%；Function additive 0.6～1.4%；Dimethylethanolamine 1～2.2%；Cosolvent 5～6%；Increase Thick dose 0.2～0.6%；Deionized water 22～30%.CN104072657A discloses a kind of water-borne acrylic resin and packaging is held Device coating, the preparation process of water-borne acrylic resin is for adjusting monomer ratio, and by 1,1-dimethyl-1-heptyl carboxyl shrinks sweet Grease is modified, and is neutralized through 2-amino-2-methyl-1-propanol, becomes salt, it is achieved Water-borne modification, and preparation viscosity is low, to pigment The water-borne acrylic resin of good dispersion.Open a kind of hydrophilic acrylic's coating of CN104212287A and preparation method thereof, institute Stating coating and comprise acrylic emulsion, acrylic emulsion is by including that following monomer prepares through emulsion polymerization: alkyl acrylate 60-110 weight portion, cross-linking monomer 5-65 weight portion, acrylic acid and methacrylic acid 5-40 weight portion altogether, and polyhydric alcohol (first Base) acrylate 0-65 weight portion, and acrylic acid: the mass ratio of methacrylic acid is 2:(1-2), cross-linking monomer, acrylic acid, first Base acrylic acid is 70-150 part with the gross weight number of polyhydric alcohol (methyl) acrylate, the glass transition temperature of acrylic emulsion Degree is for 20-30 DEG C.
