Abstract

The invention relates to a technique for modifying mixed zinc-rich coating by adding dodecyl alcohol amine. Lithium silicate and sodium silicate serve as composite base materials, in the preparation process of the coating, a dodecyl glycol amide surfactant is added, the wettability of metal zinc powder is improved, accordingly, the modified zinc-rich anti-corrosion coating is prepared, and the comprehensive performance of the coating is greatly improved.

Description

A kind of technique of addition dodecanediol amide modifications mixing zinc-rich paint
Technical field
The present invention relates to a kind of coating, the zinc-rich paint of more particularly to a kind of addition dodecanediol amide modifications and its Preparation technology, belongs to paint chemical field.
Background technology
The whole world accounts for the 2%-4% of various countries GDP because of the economic loss that metal erosion is caused every year, because of the gold that corrosion is scrapped Category is up to more than hundred million tons.Metal erosion can significantly reduce the mechanical properties such as the intensity of metal material, plasticity, toughness, 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.Iron and steel is similarly faced with corrosion as a kind of most common metal material for using This difficult problem mesh.According to statistics, the iron and steel being directly lost due to corrosion every year, accounts for a quarter of iron and steel annual production.People Delay the corrosion rate of iron and 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 element 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 commonly use epoxy resin, chlorinated rubber, vinylite and polyurethane resin for film forming binder. But the electric conductivity of the organic binder of organic zinc-rich paint is poor.Inorganic zinc coating is divided into again two class of solvent-borne type and aqueouss. 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 due to its organic solvent-free, with free from extraneous odour, do not fire it is not quick-fried, it is free from environmental pollution etc. excellent Point, but simultaneously because solvent is few, wettability is low, thus adhesive force is good not as corresponding solvent based coating, and zinc powder is added to painting In material, due to zinc powder and the more difficult fusion of inorganic silicate, attached power with ground low.For this purpose, 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, in dope preparing process, adding dodecanediol acidamide surfactant, improving metallic zinc Powder wettability, so as to prepare a kind of modified zinc-rich anti-corrosive paint, its combination property will be greatly improved.
The content of the invention
It is an object of the invention to provide a kind of technique of addition dodecanediol amide modifications mixing zinc-rich paint, is real Existing this purpose, the coating include the raw material of following mass percent：
Lithium metasilicate 5%-10%；
Sodium silicate 5%-10%；
Ludox 20%-40%；
Silane coupler 3%-7%；
Dodecanediol amide 2%-3%；
Silicone acrylic emulsion 20%-30%；
Super-fine zinc dust 20%-30%.
A kind of technique of addition dodecanediol amide modifications mixing zinc-rich paint comprises the steps：
(1) a certain amount of Lithium metasilicate solution and sodium silicate solution are poured in container Hybrid Heating；
(2), in the case where ceaselessly stirring, the Ludox of metering is slowly added dropwise so as to be sufficiently mixed；
(3) the silane coupler and dodecanediol amide of certain metering, high-speed stirred are added toward container again；
(4) stop heating, when temperature is down to room temperature, add silicone acrylic emulsion；
(5) finally add appropriate super-fine zinc dust, persistently stir one section and can obtain a kind of modified mixing zinc-rich paint.
Preferentially, above-mentioned steps (1) in, temperature control is at 50-80 DEG C；
The present invention has following advantages and characteristic：
(1) the paint preparation process is simple, good operability；
(2) the paint good combination property for preparing；
(3) it is cheap, and environmental protection.
Embodiment one：
50g Lithium metasilicates solution and 50g sodium silicate solutions are poured in a container respectively and is mixed, and be mixed thing heating, heating Temperature control is ceaselessly stirred with blender at 60 DEG C or so.In whipping process, then it is slowly added dropwise 300g Ludox, Deca After finishing, then the dodecanediol amide of the silane coupler and 20g of 30g is added toward container, and mixing speed will be improved, Stop heating after 5 minutes, when temperature is down to room temperature, add 250g silicone acrylic emulsions, finally add 300g super-fine zinc dusts, continue Stirring 10-15 minutes can obtain a kind of modified mixing zinc-rich paint.
Embodiment two：
70g Lithium metasilicates solution and 70g sodium silicate solutions are poured in a container respectively and is mixed, and be mixed thing heating, heating Temperature control is ceaselessly stirred with blender at 60 DEG C or so.In whipping process, then it is slowly added dropwise 300g Ludox, Deca After finishing, then the dodecanediol amide of the silane coupler and 25g of 35g is added toward 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 10-15 minutes can obtain a kind of modified mixing zinc-rich paint.
Embodiment three：
100g Lithium metasilicates solution and 100g sodium silicate solutions are poured in a container respectively and is mixed, and be mixed thing heating, plus Hot temperature control is ceaselessly stirred with blender at 60 DEG C or so.In whipping process, then 200g Ludox is slowly added dropwise, is dripped Add after finishing, then the dodecanediol amide of the silane coupler and 30g of 70g is added toward container, and stirring speed will be improved Degree, stops heating, when temperature is down to room temperature, adds 200g silicone acrylic emulsions after 5 minutes, finally add 300g super-fine zinc dusts, 10-15 minutes are stirred persistently by obtain a kind of modified mixing zinc-rich paint.
