Description
Technical field
The present invention relates to a kind of coating, more particularly to a kind of zinc-rich paint for adding dodecanediol amide modifications and its
Preparation technology, belongs to paint chemical field.
Background technology
The annual economic loss caused by metal erosion in the whole world accounts for the 2%-4% of various countries GDP, the gold scrapped by corrosion
Category is up to more than hundred million tons.Metal erosion can significantly reduce the mechanical properties such as intensity, plasticity, the toughness of metal material, destroy metal structure
The geometry of part, increases the abrasion between part, deteriorates the physical property such as electrical and optical, shortens the service life of equipment, very
To causing the catastrophic failures such as fire, blast.Steel is similarly faced with corrosion as a kind of most common metal material for using
This problem mesh.According to statistics, the steel being directly lost due to corrosion every year, accounts for a quarter of steel annual production.People
Delay the corrosion rate of steel by various modes.
As steel anti-corrosive is received more and more attention, zinc-rich anti-corrosive paint is widely used, and zinc-rich anti-corrosive paint is not
But air can be completely cut off, and galvanic cell protection can be formed.Zinc-rich anti-corrosive paint is divided into organic zinc-rich anti-corrosive paint and inorganic zinc-rich
Anticorrosive paint, organic zinc-rich paint is often film forming binder with epoxy resin, chlorinated rubber, vinylite and polyurethane resin.
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 class.
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 improves metallic zinc by dope preparing process, adding dodecanediol acidamide surfactant
Powder wettability, so as to prepare a kind of modified zinc-rich anti-corrosive paint.
The content of the invention
It is real it is an object of the invention to provide a kind of technique for adding dodecanediol amide modifications mixing zinc-rich paint
Existing this purpose, the coating includes the raw material of following mass percent：
Lithium metasilicate 5%-10%；
Potassium silicate 5%-10%；
Ludox 20%-40%；

Dodecanediol acid amides 2%-3%；
Silicone acrylic emulsion 20%-30%；
Super-fine zinc dust 20%-30%.
A kind of technique for adding dodecanediol amide modifications mixing zinc-rich paint comprises the following steps：
(1) a certain amount of lithium metasilicate solution and potassium silicate solution are 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 silane coupler 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 mixing zinc-rich paint.
Preferentially, above-mentioned steps (1) in, temperature control is at 50-70 DEG C；

Temperature control is ceaselessly stirred at 60 DEG C or so with mixer.In whipping process, then 300g Ludox is slowly added dropwise, be added dropwise
After finishing, then toward the dodecanediol acid amides of the silane coupler of addition 35g and 25g in container, and mixing speed will be improved,
Stop heating after 5 minutes, when temperature is down to room temperature, add 300g silicone acrylic emulsions, finally add 200g super-fine zinc dusts, continue
Stirring can obtain a kind of modified mixing zinc-rich paint in 10-15 minutes.
Embodiment three：
100g lithium metasilicates solution and 100g potassium silicate solutions are poured into a container respectively and is mixed, and be mixed thing heating, plus
Hot temperature control is ceaselessly stirred at 70 DEG C or so with mixer.In whipping process, then 200g Ludox is slowly added dropwise, dripped
Add after finishing, then toward the dodecanediol acid amides of the silane coupler of addition 70g and 30g in container, and stirring speed will be improved
Degree, stops heating after 5 minutes, when temperature is down to room temperature, add 200g silicone acrylic emulsions, finally adds 300g super-fine zinc dusts,
