Description
Technical field
The present invention relates to a kind of silicate zinc-rich paint, more particularly to a kind of addition aluminic acid trimethyl and dodecanediol
The silicate zinc-rich paint and its modified technique of acid amides auxiliary agent, belong to coating synthesis field.
Background technology
Steel is that corrosion easily occurs as a kind of most common metal material for using, major defect, according to statistics, every year
The steel being directly lost due to corrosion, accounts for a quarter of steel annual production, therefore, people are delayed by various modes
The corrosion rate of steel.As steel anti-corrosive is received more and more attention, zinc-rich anti-corrosive paint is widely used, zinc-rich anti-corrosion
Coating can not only completely cut off air, and can form galvanic cell protection.Zinc-rich anti-corrosive paint is divided into organic zinc-rich anti-corrosive paint and nothing
Machine zinc-rich anti-corrosive paint, organic zinc-rich paint is often film forming with epoxy resin, chlorinated rubber, vinylite and polyurethane resin
Base-material.But the electric conductivity of the organic binder of organic zinc-rich paint is poor.Inorganic zinc coating is divided into again solvent-borne type and aqueous
Two classes.Wherein aqueous inorganic zinc-enriched coating is by aqueous inorganic silicate（Receive, potassium, lithium）Resin, zinc powder, auxiliary agent etc. are constituted.
Aqueous inorganic zinc-enriched coating is free from environmental pollution etc. excellent with free from extraneous odour, non-ignitable not quick-fried due to its organic solvent-free
Point, but simultaneously because solvent is few, wetability is low, thus adhesive force not as corresponding solvent based coating it is good, and zinc powder is added to painting
In material, merged because zinc powder and inorganic silicate are more difficult, it is low attached power with ground.Therefore, it is general in dope preparing process, add
Plus coupling agent, improve the compatibility of metal zinc and silicate, strengthen the adhesive force of coating, but this improvement often has
Limit, in preparation process, then adds appropriate surfactant, then can play better improvement result.
The present invention is by dope preparing process, adding aluminic acid trimethyl coupling agent and dodecanediol amide surface
Activating agent, it is common to improve metal zinc wettability, so as to prepare a kind of modified zinc-rich anti-corrosive paint.
The content of the invention
It is an object of the invention to provide a kind of composite modified silicate zinc-rich paint and preparation method thereof, to realize this
Purpose, the coating includes the raw material of following mass percent：
Sodium metasilicate 10%-20%；
Ludox 20%-40%；
Aluminic acid trimethyl 3%-7%；
Dodecanediol acid amides 2%-3%；
Silicone acrylic emulsion 20%-30%；
Super-fine zinc dust 20%-30%.
A kind of preparation method of composite modified silicate zinc-rich paint comprises the following steps：
(1) a certain amount of sodium silicate solution is poured into Hybrid Heating in container；
(2) in the case where ceaselessly stirring, the Ludox of metering is slowly added dropwise, is sufficiently mixed it；
(3) again toward the aluminic acid trimethyl coupling agent and dodecanediol acid amides of the certain metering of addition in container, high-speed stirred；
(4) stop heating, when temperature is down to room temperature, add silicone acrylic emulsion；
(5) appropriate super-fine zinc dust is finally added, and persistently stirring one section can obtain a kind of modified silicate zinc-rich paint.
Preferentially, above-mentioned steps (1) in, temperature control is at 50-70 DEG C.
Preferentially, above-mentioned steps (5) in, ultra-fine zinc be 600 mesh more than.
Preferentially, above-mentioned steps (5) in, persistently stir between 15-30 DEG C.
The present invention has following advantages and characteristic：
(1) the Paint preparation technology is simple, good operability；
(2) the coating good combination property for preparing.
