Description
Technical field
The present invention relates to trade waste resource technology fields, more particularly to a kind of vitamin B6 industrial processes
Application of the black paste (hereinafter referred to as black cream) of middle generation as the curing agent component of anticorrosive paint.
Background technology
The phenomenon that metal is damaged by chemistry or the electrochemical action of surrounding medium referred to as metal erosion.With society
It can develop and industrial technological advancement, the use scope of metal is more and more extensive, and corrosion of metal problem has spread national economy
Every field, according to the investigation statistics of World Developed Countries, every year since direct losses caused by corrosion account for about national economy production
The 2.5%~4.2% of total value, and it is estimated that there are about 20% metal materials can not be recycled because being corroded in the world, 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
More measures, but safeguard measure or coating protection most universal, most economical, most practical so far, anticorrosion with coat are constructed with it
It is easy, economic and practical, not by device area, shape constraint and have the characteristics that certain decorative effect and widely answered
With.
Chemical industry equipment preserving method：(1) method (3) electrical anticorrosion method of method (2) face coat of environmental treatment.
The present invention is mainly to consider that the method for face coat carrys out anti-corrosion.
Corrosion mechanism can substantially be divided into three classes：Chemical attack, physics corruption candle, electrochemistry corruption candle
Mainly there are three aspects for the anticorrosion mechanism of anticorrosive paint：The passivation corrosion inhibition of matrix, Isolated Shield are acted on and
Form electro-chemical protection
Refer to changing the surface property of matrix, for example pass through the pigment in paint coatings to the passivation corrosion inhibition of matrix
Change, its matrix current potential is made to be moved towards positive direction, thus metal begins to be passivated, and can thus play the mesh for delaying corrosion
's.
Isolated Shield acts on, and is the coating by being formed in metal base surface, is just forming one in metal base surface
A barrier layer can be isolated and shield the medium such as contact of oxygen gas and water and acid-alkali salt with metallic matrix, to reach to Metal Substrate
The purpose of body protection.
Electro-chemical protection is formed, is by the way that current potential metal packing more more negative than parent metal is added 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 sacrifice dissolving occurs first is the metal packing as anode, such metallic matrix
Just protect, to have the function that matrix protect, this kind of coating thus be sacrificial anticorrosive paint.
Invention content
The technical problem to be solved by the present invention is to provide a kind of more carboxylic class solid wastes of polyamines for the above-mentioned prior art to exist
As the application of curing agent in anticorrosive paint, the remaining waste residue that vitamin B6 is produced in industrial production can be efficiently used, and right
The effective anti-corrosion of metal equipment.
The technical solution adopted in the present invention is：The black paste generated in vitamin B6 industrial processes is in anti-corrosion
As the application of curing agent in coating.
By said program：The black paste generated in vitamin B6 industrial processes is reacted into generation with epoxy resin
Object is applied to metal surface, cures drying and forming-film at a certain temperature and obstructs chemical reagent to reach corrosion-resistant purpose.
By said program：Solidification temperature is 120~150 DEG C.
By said program：Hardening time is 30~60min.
By said program：The black paste and asphalt mixtures modified by epoxy resin generated in the added vitamin B6 industrial processes of reaction
Fat mass ratio is 3:1~1:3.
By said program, it is characterised in that：The black paste and asphalt mixtures modified by epoxy resin generated in vitamin B6 industrial processes
Fat reaction temperature is that 0.5-5h is first heated 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 the reaction vessel, after black cream is completely dissolved,
It is added in the epoxy resin to reaction vessel of corrresponding quality for 1: 1 according to the mass ratio of black cream and epoxy resin, in 90 DEG C of oil
2h is stirred in bath, improves temperature to 180 DEG C of stirring 1h, until for use after viscosity is suitable.
The beneficial effects of the invention are as follows for vitamin B6 waste residue resource reutilization and to the effective anti-corrosion of metal, improve
Industrial effective income, while solving environmental issue.
