Description
Technical field
The present invention relates to paint field, more particularly to a kind of preparation method of water paint.
Background technology
Water paint is widely used in the fields such as building, automobile as a kind of environmental type coating.With building row
Industry and automobile industry develop rapidly, and the requirement of urban construction etc. improves constantly, the demand of high-performance aqueous coating by
It is cumulative strong.
At present, the exploitation of coating all over the world is based on environment-friendlywater-based water-based paint.Water paint has the advantage that：1. water
Property coating conventional organic solvent is substituted with water as solvent, substantially reduce environmental pollution, there is obvious reduce to pollute, save money
The advantage in source.Even if still there is part water paint still to improve severe operation with a small amount of hypotoxicity alcohol ethers organic solvent at present
Environment, but the mass ratio of organic solvent（Account for coating）Control is in the range of 10%-15%, or even part cathode electrophoresis dope is organic
Solvent is reduced to 1.2%.2. water paint can directly coat construction under moist surface and environment, it is to material table
Face adaptability is very good；And water paint coating tool can be washed directly with clear water, greatly reduce the consumption of organic washing solvent
Amount, avoids secondary environmental pollution.Therefore environment-friendly type coating, exploitation water paint are greatly developed into the weight of China's paint development
Weight.
At present, water paint is mainly prepared by waterborne polyester, due to containing largely in water in waterborne polyester structure
Property environment facile hydrolysis ester bond and a certain amount of hydrophilic functional group, as the water paint prepared by waterborne polyester easily exist storage
Deposit the potentialities such as stability, water resistance deficiency.Polyester water dispersion generally existing storage stability is not good enough at present, hydrolytic resistance,
The equal Shortcomings such as water resistance and film processability.
The content of the invention
The present invention solves the technical problem of provide a kind of preparation method of water paint, it is possible to increase water paint
The performance such as storage stability, hydrolytic resistance, water resistance and film processability, extend its useful life, and the letter of its technique
It is single, easy to operate.
In order to solve the above technical problems, one aspect of the present invention is：A kind of preparation of water paint is provided
Method, comprise the following steps：
（100）First by 8-hydroxyquinoline in polyglycol solution according to 1：3.5 mass ratio dissolving, it is molten to obtain the first mixing
Liquid；
（200）Then by silicon dioxide gel and dimethyl silicone polymer in deionized water according to 4:0.5：100 mass ratio
Dissolving, and high-speed stirred is uniform, obtains the second mixed solution；
（300）By the first mixed solution according to 1:30 mass ratio is added in the second mixed solution, and high-speed stirred is uniform, obtains
3rd mixed solution；
（400）In the 3rd mixed solution add mass fraction be the 3rd mixed solution 48%-50% modified aqueous epoxy resin,
The work(that mass fraction is the 3rd mixed solution 23%-25% aqueous polyester resin and mass fraction is the 3rd mixed solution 3%-5%
Can monomeric phosphate ester, and high-speed stirred it is uniform after produce.
In a preferred embodiment of the present invention, the stir speed (S.S.) during high-speed stirred is 2050-2200r/min.
In a preferred embodiment of the present invention, the molecular weight of the polyethylene glycol is 400.
The beneficial effects of the invention are as follows：Pass through the reasonable selection and proportioning of raw material and the optimization of technique, it is possible to increase water
The performances such as storage stability, hydrolytic resistance, water resistance and the film processability of property coating, extend its useful life, and its work
Skill is simple, easy to operate.
