Abstract
The invention discloses a kind of waterborne epoxy modified acrylic resins and preparation method thereof, belong to chemical technology field.By the acrylic resin of bulk polymerization, there is emulsifiability, the waterborne epoxy modified acrylic resin that drying is rapid, mechanical performance, stability and anti-corrosive properties are excellent has been synthesized by emulsion reaction with epoxy resin at low temperature.Waterborne epoxy modified acrylic resin prepared by the present invention is applied in aqueous industrial anticorrosive paint, obtained aqueous industrial anticorrosive paint, have the characteristics that adhesive force is strong, hardness is high, fast drying, impact resistance are excellent, it is solvent-free in the aqueous industrial anti-decaying paint system, VOC free discharge, performance can meet or exceed the performance indicator of the solvent based coating of same type, since solvent usage is low, reaction temperature is low, so, it can achieve environmental protection and energy saving truly, also greatly improve the safety in transport and construction, be suitable for promoting on a large scale.
Description
Technical field
The invention belongs to chemical technology fields, are related to a kind of waterborne epoxy modified acrylic resin, are additionally related to the water
Property epoxy modified acrylic resin is in aqueous industrial preparation method of anticorrosion paint.
Background technique
With developing to low pollutionization for coatings industry and application techniques, water paint increasingly rises.Water paint
Reduce organic solvent to harm and pollution caused by environment, has ensured the health of constructing operation personnel, reduced painting
The synthesis production cost of material makes coatings enterprises produce cleaning more safe and convenient in transport, while being convenient for tool again.Water
Property coating resource-saving, save the energy, it is environmentally protective, as a kind of coating of low VOC emission, there is necessity of research and development, it may have wide
General application prospect.
The common water-base resin of water paint divides from major class: water emulsification type and aqueous dispersion type and water-soluble salt form.Subdivision
Change can be divided into: water soluble acrylic acid, aqueous polyurethane, water alcohol acid, water-base epoxy etc..Acrylic resin is by esters of acrylic acid
With resin made of methyl acrylic ester and other vinyl monomer copolymerizations, by selecting different resin structure, different matching
The resin of the different shapes such as solid-state, solution, latex can be obtained in side, production technology and solvent composition, different polymerization methods, is applicable in
Multiple use.The coating made of it, with it is excellent it is fast light, weatherability, not yellowing, keep high glaze performance for a long time, and have
Have and be grafted, be copolymerized and blending and modifying with other monomers and polymer, obtains excellent water-fast, chemical resistance, anti-pollution
Corrosivity etc. is contaminated, many fields such as coating, adhesive, ink, weaving and leather agent are widely used in.With traditional solvent type
Coating is compared, and water paint has many advantages, such as using safe, is reduced environmental pollution and public hazards thus is had become current development coating
The Main way of industry.Water-based acrylic resin coating is with fastest developing speed in water paint, the most pollution-free coating of kind.
Water-based acrylic resin includes that emulsion acrylic resin, aqueous acrylic resin dispersion and acrylic resin are water-soluble
Liquid.Lotion is mainly vinyl monomer emulsification the synthesizing under the initiation of water-based free radical initiator in water by oiliness, and is set
Rouge aqueous dispersion is then that by free solution polymerization or gradually the different technique such as polymerisation in solution synthesizes.From particle diameter
It sees: the water-soluble liquid particles of emulsion particle ﹥ resin dispersion particle ﹥.
Acrylic emulsion is mainly used for the base-material of emulsion paint, important application is occupied in Building-coating market, it is answered at present
With also constantly expanding；Pure-acrylic emulsion, styrene-acrylic emulsion, silicone acrylic emulsion etc. are generally divided into according to monomer composition.
The synthesis of acrylic acid water dispersoid generallys use solution polymerization process, and solvent is answered miscible with water；In addition, Monomer Formations
In often containing carboxyl, ammonium salt is neutralized into amine, then under strong stirring, water is added and obtains the acrylic acid point of cationic
Granular media such as contains hydroxyl, ether, amide groups on the side chain of synthetic resin, can also increase the water solubility of resin.Developing water
Property acrylate paint can guarantee the coating various characteristics under conditions of, in order to increase solvent resistance, also with such side
Method is modified it with epoxy.Epoxy resin is the polymer containing epoxy group, carries out reacting friendship with curing agent or fatty acid
Connection forms the macromolecular of reticular structure, can the excellent coating resin of processability.Epoxy resin coating chemical resistance is excellent, alkali resistance
It is prominent, there is excellent adhesive force to metal, ceramics, concrete, plastics isopolarity ground.Generally introduce in the synthesis process
Epoxy resin, molecular weight is not too big, and dosage cannot be excessively high, and otherwise resin is not easy to emulsify, and reduces the stability of storage.It is such
Water-base resin is mainly used in the industrial coating of air drying, such as: machinery industry, steel construction industry etc..
Water-soluble acrylic ester coating is made of the copolymer resin of active cross-linking functional group, polyphyly thermosetting property
Coating, in painting outside plus or crosslinked resin is not added, crosslinking forms the paint film of three-dimensional-structure when making the film forming between active function groups.
The water-base resin is mainly used on the paint line with roasting plant.
Acrylic resin is coating one of most important resin, and raw material sources are extensive, and formula flexibly, can pass through various
The collocation of monomer or the modification of functional monomer, and resin various characteristics are assigned, it can almost apply to all types of coating
Among.Water-based acrylic resin can be made different types of water paint, can be made by different polymerizations
VOC content greatly reduces, and the VOC content of the coating system thus prepared is very low, meets the development side of modern coatings industry environmental protection
To with great market prospects.However emulsion acrylic resin poor water resistance, put forth effort difference.It is used on steel, has been easy sudden strain of a muscle
Rust phenomenon, aqueous dispersion, in the synthesis process, the monomer of meeting remained unreacted leads to paint film early stage poor water resistance, thermosetting property
Water-base resin cannot be used due to being limited by execution conditions on large-sized object.These drawbacks require to pass through modification
To solve.Therefore, the waterborne epoxy modified acrylic resin of function admirable is developed, there will be great social environment benefit.
