SiO2/ epoxy-acrylate watery anti-corrosion paint.
In the present embodiment, step 1) in, the mass fraction that NaOH accounts for anti-corrosive pulp is 0.15%.
Influence of the pH value to coating stabilization performance
Because the slurry prepared is in stronger acidity, therefore slurry must be adjusted to neutrality with NaOH in pulping process, it is no
Then in the preparation process of water paint, easily there is neutralization reaction in Acid Slurry, each in influence water paint with the latex of alkalescence
The dispersity of component, and there are the wild effects such as be demulsified, harden.
Influence of the NaOH consumptions to coating stabilization performance is shown in Table 2.As known from Table 2, the addition of NaOH be 0.15% (wt,
Mass fraction, similarly hereinafter) when, the stability of coating is optimal.Too low NaOH additions can make coating occur demulsification, it is tacky and hard
Change phenomenon, excessive NaOH is both unnecessary while or can increase alkali to corrosion of metal.
Influence of the NaOH consumptions of the table 2 (accounting for the weight fraction of slurry) to coating stabilization performance
Influence of the epoxy/acrylic acid ester mol ratio to coating property
Influence of the epoxy/acrylic acid ester mol ratio to coating property is shown in Table 3.As known from Table 3, epoxy/acrylic acid ester rubs
Your proportioning for 1: 1 when, the decay resistance of water paint, adhesion property and weather resistance are preferable.Because both mole
Match for 1: 1 when, molecule is engaged must be compared closely, modified best results.Any one of epoxy resin and acrylate
It is excessive, can influence the combination property of coating.Epoxy resin excess, the weather resistance of coating is poor；Acrylate excess, coating
Corrosion resistance, adhesion property it is general.
Influence of the epoxy/acrylic acid ester mol ratio of table 3 to coating property
Face filler to coating antiseptic corrosion can influence
Ferric oxide red colorant has superior high temperature resistant, alkaline-resisting, fast light and salt spray resistance, mica powder, wollastonite, talcum
The sheet inert filler such as powder, the stable in physicochemical property of themselves can prevent wearing for corrosive medium after filling with stacked together
Thoroughly, so as to play initial physical shielding effect.Trbasic zinc phosphate and aluminium triphosphate are added as filler, the ion of their hydrolysis
Can be reacted with ferrous ion, the protection thin layer of densification be formed in metal surface, so as to blocked corrosive medium enter to metal
One step is corroded.
Result shows, in the coating while adding iron oxide red, mica powder, wollastonite, talcum powder, trbasic zinc phosphate and trimerization phosphorus
Sour aluminium is combined as color stuffing by physical shielding and chemical preservation, can greatly enhance the Corrosion Protection of coating.

6. the preparation method of the watery anti-corrosion paint in a kind of claim 5, it is characterised in that:Comprise the following steps：
1) anti-corrosive pulp is prepared：Water intaking, bactericide are added in stirred tank, and 500r/min stirs, and is subsequently adding film forming and helps
Agent, ethylene glycol, dispersant, wetting agent, hydroxyethyl cellulose, defoamer and multifunctional assistant, 500r/min stir；
In above-mentioned dispersion liquid whipping process, be slowly added to trbasic zinc phosphate, aluminium triphosphate, mica powder and iron oxide red, talcum powder,
Wollastonite, titanium dioxide, barium sulfate, 1800~2000r/min is adjusted to by stir speed (S.S.), disperses 16~18min, adds hydroxide
Sodium is ground to granularity less than 40um to adjust pH value as 7, obtains final product anti-corrosive pulp, stand-by；
2) paint：Be slowly added to step 1 toward stirred tank) in ground anti-corrosive pulp, under 400r/min stirring at low speed, gradually
The latex and thickener, levelling agent, butyl glycol ether and defoamer in claim 2 are added, is stirred, that is, modified receiving is obtained
Rice SiO2/ epoxy-acrylate watery anti-corrosion paint.
7. the preparation method of watery anti-corrosion paint as claimed in claim 6, it is characterised in that:Step 1) in, NaOH
The mass fraction for accounting for anti-corrosive pulp is 0.15%.
