Description
Technical field
The present invention relates to trade waste resource technology field, more particularly to a kind of vitamin B6 industrial processes
The black paste (hereinafter referred to as black cream) of middle generation as the curing agent component of anticorrosive paint application.
Background technology
The phenomenon referred to as metal erosion that metal is damaged by the chemistry of surrounding medium or electrochemical action.With society
Can develop and industrial technological advancement, the use scope of metal is more and more extensive, and corrosion of metal problem is throughout national economy
Every field, according to the investigation statisticses of World Developed Countries, produces because the direct losses that corrosion is caused account for national economy every year
The 2.5%~4.2% of total value, and according to estimates, the metal material that 20% is there are about in the world cannot be reclaimed because being corroded, thus
Corrosion of metal and protection question cause the most attention of countries in the world.In order to reduce the loss of corrosion, people take very
Many measures, but most universal, most economical, most practical so far safeguard measure or coating protection, anticorrosion with coat are constructed with it
It is easy, economic and practical, widely should by device area, the constraint of shape and the features such as with certain decorative effect
With.
Chemical industry equipment preserving method:(1) method (3) electrical anticorrosion method of method (2) face coat of environmental treatment.
The present invention mainly considers that the method for face coat carrys out anti-corrosion.
Corrosion mechanism can substantially be divided three classes:Chemical attack, the rotten candle of physics, the rotten candle of electrochemistry
The anticorrosion mechanism of anticorrosive paint mainly has three aspects:Passivation corrosion inhibition to matrix, Isolated Shield effect and
Form electro-chemical protection
Refer to the surface property for changing matrix, such as by the pigment in paint coatings to the passivation corrosion inhibition of matrix
To change, its matrix current potential is set to be moved towards positive direction, thus metal begins to passivation, can thus play the mesh for delaying corrosion
's.
Isolated Shield is acted on, and is the coating by being formed in metal base surface, is just forming one in metal base surface
Individual barrier layer, just can isolate and shield the medium such as contact of oxygen gas and water and acid-alkali salt with metallic matrix, so as to reach to Metal Substrate
The purpose of body protection.
Electro-chemical protection is formed, is by adding current potential metal packing more more negative than parent metal in anticorrosive paint
Such as zinc powder or aluminium powder, when there is coating of the electrolyte through Isolated Shield to penetrate into metal surface, such electronegative metals
Filler just forms battery with metallic matrix, and what sacrifice dissolving occurred first is as the metal packing of anode, such metallic matrix
Just protect, so as to reach to matrix protection effect, this kind of coating thus be sacrificial anticorrosive paint.
The content of the invention
The technical problems to be solved by the invention are directed to above-mentioned prior art and provide a kind of many carboxylic class solid wastes of polyamines and exist
As the application of curing agent in anticorrosive paint, the remaining waste residue of production vitamin B6 in industrial production can be effectively utilized, and it is right
The effective anti-corrosion of hardware.
The technical solution adopted in the present invention is:The black paste produced in vitamin B6 industrial processes is in anti-corrosion
As the application of curing agent in coating.
By such scheme:The black paste that will be produced in vitamin B6 industrial processes reacts generation with epoxy resin
Thing is applied to metal surface, drying and forming-film is solidified at a certain temperature and intercepts chemical reagent to reach corrosion-resistant purpose.
By such scheme:Solidification temperature is 120~150 DEG C.
By such scheme:Hardening time is 30~60min.
By such scheme:The black paste and asphalt mixtures modified by epoxy resin produced in the added vitamin B6 industrial processes of reaction
Fat mass ratio is 3:1~1:3.
By such scheme, it is characterised in that:The black paste and asphalt mixtures modified by epoxy resin produced in vitamin B6 industrial processes
Fat reaction temperature is first to heat 0.5-5h at 50-90 DEG C, improves temperature to 60-200 DEG C of heating 0.5-3h.
One of concrete scheme is:Black cream and 1,2-PD are added in reaction vessel, after black cream is completely dissolved,
According to epoxy resin to the reaction vessel that black cream and the mass ratio of epoxy resin are 1: 1 addition respective quality, in 90 DEG C of oil
2h is stirred in bath, temperature to 180 DEG C of stirring 1h is improved, it is suitable rear stand-by to viscosity.
The beneficial effects of the invention are as follows the resource reutilization for vitamin B6 waste residue and the anti-corrosion effective to metal, improve
Industrial effective income, while solving environmental issue.
Specific embodiment
