Description
Technical field
The present invention relates to high-molecular coating technical fields, and in particular to a kind of waterborne epoxy coatings.
Background technique
Coating, in the entitled paint of Chinese tradition.So-called coating be coated in the body surface being protected or decorated, and
The continuous film of firm attachment can be formed with coated article, usually based on resin or oil or lotion, add or do not add face
Material, filler add corresponding additive, the thick liquid being formulated with organic solvent or water.Coating is a kind of material, this material
Material can be coated in object surface with different construction technologies, and formation adherency is secured, has some strength, continuous solid-state thin
Film.The film common name film formed in this way, also known as paint film or coating.The service life of coating is depending on different products, liquid
State fibrous gypsum texture product uses modified organic silicone resin lotion for base-material, and with special coating technology, assorted colored paint is overmolding to
Gluey hydrate colour particle, is uniformly and stably suspended in specific water-borne dispersions, and various colored particles form and aspect remain unchanged,
Coloring pigment will not be precipitated in water.The service life of so this exterior coating is about 15 years.Before 20 middle of century,
Solvent based coating is widely used in coating and the anti-corrosion protection of all kinds of buildings, industrial product and steel iron facilities.Since west
Developed country puts into effect the laws and regulations of limitation VOC emission and the oil crisis in 1970s outburst, promotes coating work
Industry gradually develops to the direction of clean type and resource-conserving.Therefore, various environmental-friendly coating such as water paints, radiation are solid
Changing coating, solventless coatings and high solid coating becomes the important directions of paint development, and wherein water paint is outstanding with its
Environment friendly and safety in utilization have become a hot topic of research.Water paint is with water as solvent or to make the painting of decentralized medium
Material.It has it is nontoxic, it is tasteless, it is cheap, it is resourceful the features such as, organic solvent volatilization can be greatly reduced in coating to big
It is polluted caused by gas, and using water as solvent, can greatly improve safety of the coating in storage, transport and work progress
Property.Currently, water-based anticorrosive paint has been successfully applied to building decoration, automobile manufacture, ship and Production Container, railway machine
Vehicle, aerospace, traffic bridge and woodwork coating etc..Water-based anticorrosive paint specifically includes that aqueous inorganic zinc-enriched coating, aqueous ring
Four major class of oxygen coating, water-borne acrylic coatings and aqueous polyurethane coating.Waterborne epoxy coatings can be divided by dispersion:
(1) water-soluble epoxy paint soluble epoxide can be divided into water soluble anion cold coating (anode electrophoresis dope) and water-soluble again
Property resin cation coating (cathode electrophoresis dope).Frequently with water soluble solid agent melamine resin, benzene for melamine
Amine-formaldehyde resins, Lauxite and isocyanates closure etc..1. the resin of water soluble anion cold coating is by hydroxy radical content
Higher epoxy resin and acid, anhydride reaction, then neutralize to obtain water soluble anionic resin with amine.2. water-soluble cationic tree
The resin of grease coating material is to be re-introduced into semi-enclosed polyisocyanates by epoxy resin and amine addition and made crosslinking agent, finally in acid
With and obtain.(2) aqueous emulsion epoxy coating emulsion type epoxy coating will be compared with low relative molecular mass using suitable emulsifying agent
Epoxy resin emulsification, and make it have good storage and stability in use.Practical middle normal temperature cured type person is water emulsification mostly
Coating.
Epoxy resin is widely used in industrial painting because having the function of strong adhesive force, very good mechanical properties and impermeabilisation etc.
Material.But epoxy resin also has the shortcomings that obvious: when it is exposed to indoor light or natural sunlight, color is easily varied,
This is because structure is easy to scission of link degradation under oxygen-containing environment when epoxy resin is by UV light long-term irradiation, generate
Color development machine group, and lead to resin discoloration, fade.Light stabilizer is added in epoxide resin material or changes epoxy resin
Property, the problems such as discoloration, colour fading, cracking, dusting and gloss retention decline can be effectively reduced.
