Description of the drawings
Fig. 1 is the flow chart of the preparation method of the epoxy heavy-duty anticorrosive coating in the embodiment of the present invention.
Specific embodiment
For technical scheme of the present invention and advantage is more clearly understood, below in conjunction with drawings and the specific embodiments, to this
Invention is described in further detail.
In the inventive solutions, inventor after research and test of many times by having found, nano-scale particle is to epoxy
The properties of resin are significantly improved effect, and reason is：Nano particle and basal body interface cementation are strong, and due to
The small-size effect of nano particle so that be conducive to stress transfer during coating stress, and the serious coordination of nano-material surface is not
Foot, shows extremely strong activity, therefore further promote the cross-linking reaction of resin, improves intermolecular bonding force, while make painting
Layer is fine and close and wearability improves.Moreover, the grain size of micron particles is larger, the fortune of polymer segment in composite coating can be hindered
It is dynamic, so as to influence the shock resistance epoxy group of coating the effect much larger than Van der Waals force is generated with nano-particle on interface
Power forms ideal interface, therefore can play the role of causing micro-crack well, absorb energy.Therefore, nanometer is utilized
Technology is modified organic coating anti-corrosion material, can effectively improve its comprehensive performance, particularly increase material mechanical strength,
Hardness, adhesive force improve light resistance, resistance to ag(e)ing, weatherability etc..
For example, Nano-meter SiO_22Particle has tridimensional network, due to the ratio that the serious coordination in surface is insufficient, huge
The features such as surface area and oxygen debt surface, makes it show extremely strong activity, it is easy to and the oxygen of epoxy ring molecule plays chemical combination and makees
With improving intermolecular bonding force, make the intensity of epoxy coating, increased substantially towards property, ductility, corrosion resistance etc..Separately
Outside, nanometer Al2O3Particle also contains three-dimensional crosslinked network, has the high rigidity, high intensity, thermal stability good, wear-resisting, anti-corrosion etc. excellent
Point.Therefore, after being added in epoxy coating, time chemical bonds, enhancing can occur with the functional group of epoxy for nanoparticle
The binding force of film forming matter and Nano filling, reduces the capillarity of coating and improves the shielding properties of coating, so as to
To increase the hardness of coating, impact resistance, the scratch resistance of coating and resistance to punching candle polishing machine are improved.
In addition, scale refers to that metal and certain inorganic compounds after either physically or chemically handling, become certain grain size
With the thin slice of thickness.Common scale has glass flake, mica flake, micaceous iron oxide scale, graphite flakes, allumen squama
Piece, stainless steel flakes and basalt scale.Inventor after research and test of many times by having found, if added in anticorrosive paint
Enter scale aggregate, high performance corrosion-proof resin and corresponding additive, then can be configured to various anticorrosive paints.Due to flake paint
It is multilayer chip structure, the staggered floor thick film of parallel superposition can be formed, generates special " labyrinth " effect, not only coating is divided
The shrinkage stress and the coefficient of expansion of coating are reduced, and medium detour is forced to be penetrated into many small spaces, so as to delay corruption
It loses Medium Diffusion and invades approach and the time of matrix, thus with splendid permeability resistance, impact resistance, wearability and corrosion resistant
Corrosion can extend the service life of coating.
For example, basaltic source is wide, at low cost, belongs to resource-conserving, environmental type material.Wherein, it is profound
Military rock scale has excellent anti-medium permeance property, and basalt, which is added into, can generate special " imitate in labyrinth in coating
Should ".Moreover, basalt scale and metal and Concrete Bond Strength are higher, minimum subzero 200 DEG C of operating temperature range, most
It is high up to 1000 DEG C, be suitable for that the temperature difference is big, working environments of harsh environmental conditions.In addition, basalt scale is with respect to glass flake
For, iron oxide, titanium dioxide, aluminium oxide, the content of calcium oxide are higher in scale, respectively 15.0%, 1.4%,
16.0% and 9.5%, and basic anhydride are then fewer, if dioxide-containing silica is 50%, and without oxidation in glass flake
Iron and titanium oxide, aluminium oxide 2%, calcium oxide 7%, silica are more than 50%.So basalt scale has than glass flake
Better resistance to acid and alkali, weatherability and wearability, and compensate for epoxy coating hardness well and have a surplus toughness deficiency, it should in heat
The defects of easily cracking under power or percussion.
Thus, it can be known that although the size class of nano material and scale is different, can both increase coating intensity and
Density enhances the shield effectiveness of coating.
So in the inventive solutions, it is proposed that a kind of to be prevented again to prepare epoxy using nano material and scale
