Abstract
The invention provides a sol-gel coating with silica nanoparticles dispersed in a sol system and a preparation method thereof; the dispersion of nanometer silica particles in a sol system facilitates the nucleation of gel, and thus an intact dense coating is formed which provides a layer of physical barrier for high-strength steel, inhibits the generation of corrosion reactions of high-strength steel, and improves the corrosion resistance of high-strength steel. Meanwhile, compared with traditional organic coatings and organic-inorganic hybrid coatings, the coating has good hardness, and good comprehensive mechanical properties.
Description
Technical field
The present invention relates to a kind of anticorrosion rete and preparation method of metallic substance, be specifically related to a kind of silicon-dioxide inorganic nano-particle and be scattered in sol-gel coating of sol system and preparation method thereof, it is specially adapted to the corrosion prevention of high-strength steel.
Background technology
Corrosion failure very easily takes place in high-strength steel under field conditions (factors), thereby causes tremendous loss.Traditional high-strength steel protective coating has cadmium and Zinc metallic coating, electronickelling and electrodeposited chromium coating and phosphate conversion film.
The sol-gel coating of organic inorganic hybridization is as a kind of novel surface protection coating; Have strong with the metallic matrix bonding force, environment is not had advantages such as harm and technical process be simple; Overcome shortcomings such as the high fragility of inorganic coating, high temperature sintering simultaneously, obtained broad research.The main raw material of the sol-gel coating preparation of organic inorganic hybridization is a silane, and organosilane generation hydrolysis in the colloidal sol process for preparation generates the very high silanol groups of a large amount of reactive behavioies (Si-OH).Sol coating is after the metal group surface; The spacial framework that polycondensation generates Si-O-Si takes place between the silanol groups; And silanol groups and metallic surface also react, and the reaction back connects through the Me-O-Si key, thereby reach the effect that covers the metallic surface.
The sol-gel coating of metallic surface organic inorganic hybridization comprises organic and inorganic two parts; Inorganic part mainly is the spacial framework of Si-O-Si; It is the skeleton part of whole coating; And organic moiety mainly is made up of organic segment that hydrolysis do not take place organosilane, and this part can be good at remedying the inorganic coating poor toughness, be prone to crack and be difficult to and obtain than shortcomings such as thick film layers.Organic moiety possibly produce two shortcomings but simultaneously: 1, the comprehensive mechanical property of coating reduces; 2, the residual hole of meeting after the volatilization of the organic solvent on surface influences its compactness and corrosion resisting property.The solution of these two shortcomings normally changes the adding kind or the concentration of silane, is that organic segmental kind and content change after the hydrolysis, changes organic and the ratio of inorganic components in coating, thereby improves the over-all properties of coating.
The present invention considers from the gel nucleation process, in sol system, adds Nano particles of silicon dioxide to improve the over-all properties of sol-gel coating.Forming core and the attaching process of gel on matrix has significant effects to the compactness and the corrosion resisting property of sol-gel coating; Generally; Can form the particle of nanoscale after the silane generation part polycondensation after the hydrolysis, these particles can become the starting point of sol-gel coating forming core.But polycondensation forms the influence that particulate quantity can receive the colloidal sol environment, and particulate quantity can influence the homogeneity and the compactness of the coating that forms.The inorganic nano-particle of nanoscale is dispersed in the sol system,, will helps the formation of densification, uniform coating for the forming core of collosol and gel in the metallic surface provides more starting point.
Summary of the invention
The purpose of this invention is to provide a kind of Nano particles of silicon dioxide and be scattered in sol-gel coating of sol system and preparation method thereof; The silicon dioxide granule of nanoscale is distributed in the sol system; Help the forming core of gel, thereby form complete, fine and close coating, for high-strength steel provides one deck physical barriers; Thereby the generation of corrosion reaction on the inhibition high-strength steel, the corrosion resisting property of raising high-strength steel.This coating is compared with the hybrid inorganic-organic coating with traditional organic coating simultaneously, has higher hardness, and comprehensive mechanical property is better.
Collosol and gel rete of the present invention adopt tetrabutyl titanate (TBT) (>=98wt.%) and γ-Huan Yangbingyangbingjisanjiayangjiguiwan (GTMS) (>=98wt.%) as presoma, the reagent that uses is all analytical pure.
The present invention adopts absolute ethyl alcohol as solvent.
The present invention adopts the salpeter solution of pH=1 as catalyzer, the hydrolysis and the condensation rates of control siloxanes.
The present invention adopts Nano particles of silicon dioxide to mix as the external world and joins sol system.

3. load weighted 20ml tetrabutyl titanate is joined in the mixed solution, sealing was stirred 20 minutes;
4. with stirring 0.5 hour under the said mixture room temperature, ultrasonic vibration promoted the dispersion of nanoparticle in 0.5 hour again;
5. dispose the salpeter solution of pH=1, this solution of weighing 20ml, and dropwise join in the above-mentioned mixed solution;
6. 2h is stirred in sealing under the room temperature.
3) preparation of sol-gel coating
1. dip-coating: the high-strength steel sample that will pass through pre-treatment impregnated in 100-120s in the sol system that configures, and comes out with the VELOCITY EXTRACTION of 1-3mm/s then;
2. surface drying: in air, place about 10min, place 60 ℃ of held 10min again;
3. repeat 1. and 2. step the dip-coating 3 times repeatedly of every group of sample;
4. solidify with dry: place 60 ℃ of following 2h, 90 ℃ of following 1h and 120 ℃ 0.5 hour so that the rete complete drying.
The invention has the advantages that: Nano particles of silicon dioxide under the katalysis of acid with the water hydrolytic reactions; Form active oh group on the surface; The surface active groups generation polycondensation of the GTMS and the TBT of hydrolysis has taken place in these activity hydroxy groups and the colloidal sol; Generated a kind of combination of covalent linkage, bonding force is very strong.Because the quantity of nanoparticle is very many, reactive group each other and the polycondensation resultant on the reactive group be further polycondensation again, forms very stable spacial framework, makes sol-gel coating have higher density and intensity.This coating is compared with the hybrid inorganic-organic coating with traditional organic coating; Has higher hardness; Comprehensive mechanical property is better, repeatedly applies and rete interior laminate layer phenomenon do not occur, and the collosol and gel thickness of preparation can reach 5～7 μ m; Can be the high-strength steel sample one deck physical barriers is provided, play the corrosive effect that prevents.
