Adhesion.
Technical solution：A kind of preparation method of motor anticorrosion finishing coat, ingredient by weight, include the following steps：
（1）30-50 parts of phosphoric acid and deionized water are subjected to mixed dissolution and obtain phosphoric acid solution, the weight ratio of phosphoric acid and deionized water is
1:1-1.1；
（2）Phosphoric acid solution is heated to 86-92 DEG C, and is stirred；
（3）It is slowly added to aluminium hydroxide, speed is 6-10 parts/h, while being warming up to 110-120 DEG C, this temperature is kept to stir 1.5-
2h is transparent to solution；
（4）It is cooling, and adjusting solution ph is 1.47-1.48；
（5）Be added 50-80 part deionized waters, while stirring addition 5-10 parts of silica solution, 1-2 parts of refractory aggregates, 2-5 parts of dispersing agents,
2-4 parts of chelating agents, 10-20 parts of aqueous epoxy resins, 2-5 parts of polyvinylpyrrolidones and 1-2 parts of neopelexes；
（6）It is transferred in Ultrasound Instrument ultrasound 30-50min to obtain the final product.
It is further preferred that the dispersing agent includes polyethylene glycol 200, sodium metnylene bis-naphthalene sulfonate, enuatrol.
It is further preferred that the chelating agent is one or more of tartaric acid, citric acid, gluconic acid or phytic acid.
It is further preferred that the refractory aggregate is magnesite clinker, burnt dolomite, alabaster, spinelle, zircon or height
One or more of furnace slag.
A kind of preparation method of motor anticorrosion finishing coat according to claim 1, it is characterised in that：It is described resistance to
The partial size of fiery aggregate is 1-2mm.
Beneficial effect：
1. silica solution makes surface extra hydroxyl occur by the hydroxyl in absorption water, thus increase space net structure, hydroxyl
The introducing of base not only changes the reticular structure of colloid, while will limit the value of colloidal solution, the hydroxyl dissociation of introducing, ties net
The electrification of structure surface, thus change the value of solution, in film forming assimilation process, trifoliate orange, energy due to silica sol particle huge ratio table
Enough uniform package electrode material surfaces, so that homogeneous film formation, guarantees the bond strength of film.So the reticular structure of silica solution
The rheological characteristic that can be good at controlling finishing coat, makes coating smooth even.
2. silica solution forms hydrogen bond with the extra group in finishing coat and links together, increases reticular structure, increase finishing coat
Cohesive force improves the adhesion strength and stability of finishing coat with this.Meanwhile the colloidal osmotic power of silica solution is strong, can pass through capillary
Effect is penetrated into inside motor material, and the mutual cohesive force between finishing coat and motor material is further enhanced.
3. aqueous epoxy resins crosslink at high temperature with silica solution, organic siliconresin is formed, which contains base
Group makes film have high-fire resistance, hydrophobicity, while can effectively enhance toughness and waterproofness of finishing coat etc..
4. finishing coat of the present invention has good anticorrosion ability, salt fog resistance is good, still without rust spot after 200h, simultaneously also
With extraordinary adhesion.
