Abstract
Production water-based acrylic resin antirust emulsion is carried out by adding into universal acrylate, acrylamide, dimethyl amino-ethyl ester methacrylate, chlorethylene and meta-acetylenedichloride and polymerizing. It adopts TON-953 emulsifier and has better antirust effect.
Description
Technical field
The invention belongs to the painting technical field and relate to antirust emulsion of water acrylic resin and manufacture method thereof.
Antirust emulsion is a kind of rust proof paint.For antirust, when the chief of a tribe mostly uses the solvent type resin finishing agent, both caused pollution to environment, damaged HUMAN HEALTH; Waste the solvent that derives from oil in a large number again, caused the irreversible loss of the energy.
In order to overcome the unsurmountable defective that the solvent-borne type rust proof paint exists, people want to replace valuable solvent with water naturally, and manufactured experimently some polymer water dispersions be used for antirust, yet the metal water breakthrough promptly becomes rusty, people are called " dodging rust ", have caused difficulty for the use of water dispersion.Be higher than 10 PH, perhaps add the material of inhibiter and so in order to overcome " dodging rust " people or water dispersion to be had.
High PH makes the dispersion instability, can not be as commodity, and operation is also inconvenient, and can corrode people's health.Current, truly have some to add the product of inhibiter, can receive certain effect sometimes, yet the adding of inhibiter is subjected to itself and external environment such as dissolved salt concentration and Temperature Influence.Inhibiter only could produce effectiveness when it surpasses a certain concentration, quicken corrosion when concentration is low on the contrary.And these materials mostly are low molecular weight substances, easily run off, easily in physical environment, change, and be illusive so add the method for inhibiter.
In current product as rust proof paint, as the polymer substance of the main body of the dispersion of base-material mostly because it to the deficiency of the wet sticking power of metal and delamination under moisture conditions makes oxygen and water be able to rapid intrusion, causes corrosion.
Summary of the invention
The present invention is conceived to improve the wet adhesion strength as the polymer confrontation metal of dispersion main body.Good wet adhesion strength, make film under wet environment also can be securely attached to metal on, oxygen and water can not be seen through film and invade the metallic surface and corrosion takes place.The present invention has synthesized the high molecular dispersion liquid with good wet adhesion strength, its key problem in technology be the acrylic resin high score on the chain with on can produce the height wet adhesion strength group.Be about to such as acrylamide Methacrylamide, vinylformic acid dimethylamino ethyl ester, monomer such as dimethylaminoethyl methacrylate and other vinyl monomer copolymerization and obtain to have the acrylic resin aqueous rust preventive emulsion of good antirust ability.
After adopting this technology in addition, need not add the difficult problem that inhibiter has also overcome ' dodging rust ' in addition.
Oxygen and moisture see through paint film and reach the basic reason that the metallic surface is corrosion, in order to improve rust-proof effect, also should make paint film have the effect that stops oxygen and moisture to see through, and the present invention has introduced monomers such as vinylchlorid or vinylidene chloride and participated in copolymerization on aforesaid basis.Obtained satisfied effect when making this class monomer account for the 10-40% of polymerization single polymerization monomer total amount.Under this monomer ratio, both can guarantee the ageing-resistant performance that it is required, reached the effect of shielding oxygen and water again, make it to be difficult for being dissolved in film and see through paint film to arrive the metallic surface.Thereby prevented the corrosion of metal.Certainly, this measure is also given paint film with fire retardation.
The present invention is achieved by the following technical programs.
Adopt the acrylic resin synthetic monomer such as the methyl methacrylate that generally use, butyl acrylate, ethyl propenoate etc.Make its amount be the 40-85% of polymerization single polymerization monomer total amount, to obtain suitable hardness and toughness.
With acrylamide, vinylformic acid dimethylamino ethyl ester or dimethylaminoethyl methacrylate etc. participate in copolymerization again, and its add-on is the 5-20% of polymerization single polymerization monomer total amount.
The vinylchlorid that also need add monomer total amount 10-40%, vinylidene chloride monomer.Above three class monomers are mixed,, carry out aqueous emulsion polymerization under emulsifying agent such as OP-10 and persulfuric acid salt initiator exist and obtain product of the present invention at TON953.
This product has been eliminated the pollution of solvent fully, has saved the energy.More overcome and dodged rust, improved rust-proof effect greatly because of having good wet sticking power again.
