Description
Technical field
The present invention relates to anticorrosive coating technical field, more particularly to a kind of automobile leaf spring nano paint and its preparation
Method.
Background technology
Acrylic monomerss are often used in the polymerization process of water-borne acrylic resin, due to the hydrophilic carboxylic on acrylic acid
The presence of base so that polymer emulsion stability strengthens, and under conditions of dry film, carboxyl can closely stick to one with ground
Rise, substantially increase the adhesive force for applying interlayer；But in wet environment, due to the carboxylated hydrophilic on acrylic acid, between water
Association it is very strong, hydrone is entered easily by capillary attraction in the interface of coating and metal, causes carboxyl with gold
The active force of category substrate surface is substantially reduced, and dampness adhesive force is performed poor, and resistance to water is reduced, and can consequently also affect film
Antiseptic property.Function phosphate ester monomer is the mixture of phosphate monoester, di-phosphate ester and a small amount of phosphoric acid；Phosphate monoester can be with
Metal base reacts and generates phosphate monoester iron salt, forms fine and close protecting film, and this all phosphate ester is just securely connected
To on base material, so as to improve the adhesive force of film；
In recent years, because special effect of the function phosphate ester in terms of film rustless property and anti-flash rusting is improved so that he is increasingly
It is taken seriously, as increasing R＆D worker begins one's study its application in water soluble acrylic acid anticorrosive paint.By its
The Corrosion Protection improved as additive is obvious, and operating process is simple, convenient, has become water-based anticorrosive paint from now on
One important development direction of research；
However, feature phosphate ester monomer mostly is import, costly, technique prepared by phosphate ester monomer is complex for price,
Domestic fewer to its building-up process systematic research, these unfavorable factors have limited to phosphate ester in water soluble acrylic acid anticorrosive paint
In application development.But more excellent, the less expensive phosphate ester of volatility is made slow progress, so, simplify the preparation technology of phosphate ester
And the utilization rate of raising function phosphate ester monomer becomes current practicable method as far as possible；Epoxy resin is to acrylic resin
Modified hardness and resistance to water to paint film increase significantly；
The modified rustless property that can efficiently improve paint film of the phosphate ester function monomer to acrylic resin, and operate letter
Just.As current fluorine-containing emulsifier and fluorine monomer are expensive, grafting efficiency is low.The present invention considers automobile leaf spring application
Particular/special requirement, adopt phosphate ester monomer and the monomer modified acrylic resin of epoxy acrylic for matrix resin；
The coating process of automobile leaf spring is：Leaf spring carries out application one by one, and then assembly is locked together is carried out again
Application.If applying thickness, during locking together, the coating between two spring leafs will be squeezed out, or even destruction is applied
Layer.If coating is too thin, general coating rustless property is poor, is not enough to protect automobile leaf spring piece, and this is accomplished by obtained
Possess rustless property as high as possible in the case that coating material coating is relatively thin.At present both at home and abroad the coating of automobile leaf spring compared with
Thickness, the destruction of too thick extruding during more or less presence coating assembly, can further become corrosion point, sternly at these destructions
The quality of the impact automobile leaf spring coating of weight, the rust-preventing characteristic for improving unit thickness coating as far as possible are increasingly becoming urgent need solution
A difficult problem certainly.Then, the present invention is modified to it using acrylic resin as matrix resin with epoxy resin, and this just makes
Antiseptic property, adhesive force that coating material had both had epoxy resin excellent are obtained, and with the excellent chemical-resistant of acrylic resin
And pliability, greatly improve the rustless property of unit thickness coating.
