Description
Technical field
The present invention relates to a kind of water paint self-emulsifying epoxy resin emulsions and preparation method thereof.
Background technology
Epoxy resin has adhesive property good, and solidfied material stability is good, high mechanical strength, and shrinking percentage and water absorption rate are low, electricity
The advantages that insulation performance is splendid, to be widely used in the industries such as coating, adhesive and macromolecule manufacture.Epoxy resin coating
It is one of the pillar product of coating industry.It is reported that the dosage of China's coating epoxy resin accounts for about the total dosage of epoxy resin
40%, it is contemplated that following country's epoxy resin industry remains to steady growth.On the one hand it is that global industrial shift makes electronics, ship etc.
Downstream industry is transferred to domestic product, has pulled the demand to epoxy resin；On the other hand it is domestic enterprise's production product
Quality is being continuously improved, and gradually has comparative advantages compared with overseas enterprise.However, traditional epoxy resin is dissolved only in aromatic hydrocarbon
And the organic solvents such as ketone.Coating industry with the topic in " water " generation " oil " always by discussing warmly, the country from 2 1st, 2015
To VOC content be more than 420 grams per liters coating impose 4% consumption tax policy landing after, traditional solvent-borne industrial coating enterprise to
The process of the environmental protections such as aqueous, powder direction transition and upgrade is irreversible.
The Water-borne modification technology of epoxy resin experienced the development course from additional emulsifier method to self-emulsification.It is general next
It says, additional emulsifier method is primarily referred to as Mechanical Method and phase inversion, and the aqueous epoxy resins prepared by the method belong to first generation water
Property epoxy-resin systems.2002, upper sea green good water paint Co., Ltd Shi Xuezhen et al. reported a kind of water-base epoxy breast
The preparation method of liquid is characterized in that and is prepared for a kind of reactive emulsifier, is then prepared as in conjunction with phase inversion aqueous
Epoxy emulsion.But additional emulsifier method, generally there are paint film chemical resistance is poor, solidfied material molecular weight is low, easily extracts from paint film
The shortcomings of taking out.
The aqueous epoxy emulsion prepared using water soluble solid agent oil emulsion soluble epoxy belongs to the aqueous ring of the second generation
The product of oxygen system.Zhou Jiliang et al. reports a kind of synthesis of nonionic waterborne epoxy curing agent, and the curing agent is in room temperature
Has the function of good emulsifying liquid epoxy resin down, after being cured at room temperature by the double-component aqueous epoxy coating of its preparation
The film of function admirable is obtained, there is good flexibility and impact resistance.But the system initial viscosity is big, constructs the time limit
Short, curing rate is slow, and certain difficulty is brought to Practical Project construction.
Self-emulsification, that is, chemic modified method, be using the active reactive group on epoxy resin, as epoxy group, secondary hydroxyl,
Methylene hydrogen etc., thus by hydrophilic radical（Amino, polyoxyethylene segment, carboxyl）It is introduced into epoxy molecule structure, makes ring
Oxygen resin has the amphiphilic performance of hydrophilic and oleophilic.The a variety of water-base epoxy products released domestic before this, technology also rest on the
On two generation water-base epoxies, the performance of solvent based coating product is also much not achieved in the coating products prepared in performance.Through inspection
Suo Faxian, the Chinese patent of Patent No. 2006100498972 disclose a kind of propylene oxide acids emulsifiers and by the emulsifiers
The preparation method of acrylic acid epoxy lotion made from emulsion acrylic epoxy ester series monomer, the method using toluene di-isocyanate(TDI) or
Triphenylphosphine is as coupling agent, and toluene di-isocyanate(TDI) at normal temperatures will be secondary anti-with the reaction of moisture in raw material and air
Product should be caused impure, and raw material not only needs dehydration, free isocyanates that can cause environment and paint film property more
Adverse effect, and the present invention is only to be prepared for a kind of emulsifier, then be prepared as lotion by emulsifier monomer, is still fallen within
Give an account of the scope of the first generation water-base epoxy to continue；The Chinese patent of Patent No. 2008100274947 discloses a kind of nonionic
The preparation method of type solid epoxy and its lotion, the method is by the catalysis of LEWIS acid boron trifluoride ether, in epoxy resin
Polyether segment has been accessed on molecule, to realize the Water-borne modification of epoxy resin, but has been difficult to after the completion of the reaction of LEWIS acid catalysts
It removes, being used for a long time can also etching apparatus, it is most important that catalyst is used as using boron trifluoride ether, reacts more violent,
The autohemagglutination of epoxy group can be caused, reaction is not easy to control.
