The tapping screw for preparing through above-mentioned steps has seal coating 15, from top to bottom successively every electropaining layer 16, multi-functional coatings 17 and locking coating 18 shown in Fig. 6 a.Shown in Fig. 6 a, when tapping screw shown in using, because the existence of seal coating 15, it has filled up the outer surface of upper of tapping screw head 11 sides and the gap between the non-Electric region territory 01, so extraneous liquid, dust etc. can't enter the non-Electric region territory, thereby form sealing.Simultaneously, because existence every electropaining layer 16, it has formed an isolation layer on lower surface that is positioned at non-Electric region territory 01 and the side of the head 11 at 02 handing-over interface, electric region territory and no screw section screw rod 13, thereby prevents that effectively 02 leakage enters non-Electric region territory 01 from the electric region territory for electric current, static etc.At last, because as the multi-functional coatings 17 of locking coating and the existence of locking coating 18, it has filled up the gap between screw section screw rod 14 and the electric region territory 02 fully, and has strengthened the frictional force between the two, thereby effectively prevents screw loosening.
Sealing in the present embodiment is specially adapted to having relatively high expectations every electric anti-loosening property the less demanding situation of sealability every electric screw.
Embodiment 14:
Adopt following technical parameter, improve embodiment one.
Shown in Fig. 6 b,, in accordance with the following methods, prepare sealing of the present invention every electric screw based on countersunk head half tooth tapping screw.
Step 1: tapping screw slowly is heated to 265 ℃.
Step 2: the tapping screw after the rotation heating, adopt nozzle to spray the tapping screw outer surface in such a way simultaneously.
The employing tilt angle is that 50 ° the outer surface of upper of nozzle to the side of the head 11 of tapping screw sprays nylon powder 11, and vertical height of spraying is 75% of the vertical height of head outer surface, forms seal coating 15.
The employing tilt angle is that 50 ° nozzle sprays nylon powder 11 to the lower external face of the side of the head 11 of tapping screw and the outer surface of no screw section screw rod 13, vertical height of spraying is 25% of the vertical height of head outer surface, formation is every electropaining layer 16, describedly joins every the top edge of electropaining layer 16 and the lower edge of seal coating 15.
The employing tilt angle is that 50 ° nozzle sprays nylon powder 11 to the outer surface of upper of the screw section of tapping screw screw rod 14, formation have with every the consistent multi-functional coatings 17 of electropaining layer effect function, the top edge of described multi-functional coatings 17 with join every the lower edge of electropaining layer 16.
Above-mentioned every electropaining layer 16 and multi-functional coatings formed jointly one complete every electropaining layer 19.
Adopt the tilt angle be 50 ° nozzle to 285 ° of sprayings of lower external face nylon powder 11 of the screw section of tapping screw screw rod 14, form locking coating 18, the top edge of described locking coating 18 with join every the lower edge of electropaining layer 19.
Described seal coating 15, be 11% of no screw section screw rod 13 diameters every the thickness of electropaining layer 19 and locking coating 18.
Step 3: slowly cooling step 2 gained tapping screws are to room temperature, 6 seconds cool times;
Step 4: the gained tapping screw is immersed in the water soluble anti-rust agent, dries subsequently.
The tapping screw for preparing through above-mentioned steps has seal coating 15, from top to bottom successively every electropaining layer 19 and locking coating 18 shown in Fig. 6 b.Shown in Fig. 6 b, when tapping screw shown in using, because the existence of seal coating 15, it has filled up the outer surface of upper of side of tapping screw head 11 and the gap between the non-Electric region territory 01, so extraneous liquid, dust etc. can't enter the non-Electric region territory, thereby form sealing.Simultaneously, because existence every electropaining layer 19, an isolation layer has been formed at its top at lower external face, no screw section screw rod 13 and the screw section screw rod 14 of the side of the head 11 that is positioned at non-Electric region territory 01 and 02 handing-over interface, electric region territory, thereby prevents that effectively 02 leakage enters non-Electric region territory 01 from the electric region territory for electric current, static etc.At last, because the existence of locking coating 18, it has filled up the gap between screw section screw rod 14 and the electric region territory 02 fully, and has strengthened the frictional force between the two, thereby effectively prevents screw loosening.
Sealing in the present embodiment is specially adapted to high every requirement on electric performance every electric screw, and to sealing with loosen the not high situation of performance requirement.
