Screw bolt and nut is taken out after dry, it is spare；
S2, spray treatment is carried out to the outer surface of screw bolt and nut, first spraying insulating moulding coating, is sent into baking oven after spraying uniformly
It is dried, after dry 0.5 ~ 1.2h, takes out bolt, anticorrosion with painting loses coating immediately, is fed again into baking oven after spraying uniformly
Be dried, after dry 0.5 ~ 1.5h, take out bolt, spray wear-preventing paint immediately, be fed again into baking oven after spraying uniformly into
Row drying after drying 1 ~ 1.6h, takes out bolt；
S3, bolt is inserted into the screw hole of workpiece, covers Upper gasket in bolt tail, then nut is tightened；
S4, upper wear-preventing paint is sprayed in the junction of nuts and bolt, is then dried up using hot wind；
S5, upper adhesive layer is sprayed again in the outside of the junction scuff-resistant coating of nuts and bolt, and dried up using hot wind, it is natural
It is cooling.
Preferably, in abovementioned steps S1, clear water is rinsed 2 ~ 3 times, and the temperature of baking oven is 60 ~ 75 DEG C, and drying time is 1 ~ 2h.
More preferably, in abovementioned steps S2, insulating moulding coating with a thickness of 15~20 μm, anticorrosive coating with a thickness of 10~
16 μm, wear-preventing paint with a thickness of 12~15 μm.
It is highly preferred that in abovementioned steps S2, the temperature sprayed three times is respectively 50 ~ 65 DEG C, 60 ~ 70 DEG C and 75 ~ 85 DEG C, three
The secondary drying temperature for being sent into baking oven is 65 ~ 85 DEG C.
It is further preferred that in above mentioned step S3, before in the screw hole of bolt insertion workpiece, first in the outer surface of screw hole
Anticorrosive coating in upper spraying, and use hot blast drying.
Specifically, in above mentioned step S3, the quantity of gasket is 2 ~ 4.
Preferably, in abovementioned steps S4,2 ~ 3 layers of wear-preventing paint are sprayed in the junction of nuts and bolt, spraying temperature is
55 ~ 75 DEG C, hot blast temperature is 60 ~ 70 DEG C.
More preferably, in abovementioned steps S5, adhesive layer is coated with 1 ~ 2 layer, and spraying temperature is 45 ~ 55 DEG C, and hot blast temperature is
60~70℃。
The invention has the beneficial effects that: the fastening method of bolt of the invention is easy to operate, fastening effect is good, exists first
Bolt surface sprays upper insulating moulding coating, anticorrosive coating and wear-preventing paint, can effectively improve heat-proof quality, the anti-corrosion of bolt
Corrosion can substantially increase the quality of bolt, increase the service life of bolt with abrasionproof performance；Screw bolt and nut is tightened it
Afterwards, upper wear-preventing paint and adhesive layer are sprayed in its junction, wearability between the two not only can be improved, reduction was being tightened
Wear intensity in journey can also be such that connection between the two more fastens, and be not easy to unclamp.
