Now to a kind of preparation of waste and old circuit board non-metal powder polydicyclopentadiene elastomer of the present invention by taking embodiment 1 as an example
Method is illustrated.
A kind of waste and old circuit board non-metal powder polydicyclopentadiene method for producing elastomers, comprising the following steps:
Step 1:
It is dried after waste and old circuit board is cleaned, selects the non-metallic component of waste and old circuit board, and by waste and old circuit board
Non-metallic component is crushed, and it is spare to obtain non-metal powder, since this is preliminary broken, the non-metal powder filtered out
The partial size at end is larger, needs to carry out regrinding crushing.
Non-metal powder to be ground is put into grinding case 1 by feed inlet, is located in the cavity of grinding table 12,
And starting first motor, first motor drives shaft rotation, to realize the rotation of grinding head 2, to dividing metal powder to grind
Mill.Non-metal powder after grinding carries out guiding by guide housing 14 and drops down on Screening Network 3, and selecting aperture is 400 μm of screening
Net 3.
After non-metal powder drops down on Screening Network 3, Screening Network 3 can move down under the gravity of non-metal powder, and work as
After non-metal powder of the partial size less than or equal to 400 μm is fallen by the mesh of Screening Network 3, the gravity that Screening Network 3 is subject to disappears,
To realize moving up and down for Screening Network 3, and during Screening Network 3 moves up, it is able to achieve the vibration of non-metal powder, thus
Improve the effect of screening.And non-metal powder of the partial size greater than 400 μm then rests on Screening Network 3.
As the non-metal powder dropped down on Screening Network 3 gradually increases, the gravity that Screening Network 3 is subject to is gradually increased, screening
Net 3 gradually moves down, when the Screening Network 3 of right end, which is displaced downwardly to, to offset with the limited block 31 on right side, under the right end of Screening Network 3 stops
It moves, and the Screening Network 3 of left end persistently moves down, so that Screening Network 3 gradually tilts.And the process persistently moved down in 3 left end of Screening Network
In, rubber block skids off sliding slot, realizes the inclination of Screening Network 3.And it drops down onto the biggish non-metal powder of partial size on Screening Network 3 and then passes through
Material guide port 13 skids off, and drops down onto collecting tank.
At this point, the gravity for the non-metal powder that Screening Network 3 is subject to reduces, to move up under the action of the spring, realization pair
The screening again of non-metal powder.Restart the second motor, so that the second motor drives the drive roll rotation of conveyer belt 6, realizes
The rotation of conveyer belt 6, when conveyer belt 6 rotates, so that supporting table 61 drives collecting tank to move up.When collecting tank is moved to conveyer belt 6
Top when, close the second motor, remove collecting tank, and the non-metal powder in collecting tank is poured into grinding case 1, carry out again
Secondary grinding.
And when the rotation of conveyer belt 6, driven voller also rotates, so that transmission shaft be driven to rotate, realizes drawstring 7 in winding wheel
Upper winding, the attraction for pulling striker plate 4 that magnet block is overcome to give iron powder layer skid off grinding case 1；And rotating wheel is unidirectional at this time
It does not rotate under the action of bearing.The sidewall extrusion that the non-metal powder on striker plate 4 is gradually ground case 1 is dropped down onto, from
And drop down onto grinding drum bottom.
After the collecting tank in supporting table 61 is removed, pushes striker plate 4 to slide into grinding case 1, realize grinding drum
Sealed bottom.During sliding striker plate 4, drawstring 7 is pulled, so that winding wheel rotates backward, realizes conveyer belt 6
Reverse movement, by supporting table 61 downwards transmit, convenient for the collection again to non-metal powder.Rotating wheel also occurs to turn simultaneously
It is dynamic, and be driven by belt, it realizes that rotation axis 5 drives stirring blade 51 to rotate, the non-metal powder of grinding drum bottom is carried out
Stirring.And by starting heating rod, realizes the drying to non-metal powder, after drying 45min, non-metal powder is taken out standby
With.
Step 2:
Choose 40kg dicyclopentadiene and 10kg ethylene oxidic ester, and by 20kg dicyclopentadiene and 10kg ethylene oxidic ester
It is thrown in agitator and stirs evenly, form mixed dispersant solution.Dicyclopentadiene is added into ethylene oxidic ester to drop
The viscosity of low ethylene oxidic ester.
Step 3:
The mixed dispersant into step 2 is added in non-metal powder after grinding secondary in 18.150075kg step 1
In solution, and mixed dispersant solution is stirred continuously during addition, so that non-metal powder is molten with mixed dispersant
Liquid uniformly mixes, and obtains mixed solution.It, can since the viscosity of ethylene oxidic ester is reduced by the way that dicyclopentadiene is added
So that be added non-metal powder when, non-metal powder will not conglomeration so that non-metal powder is uniformly mixed with mixed dispersant solution
It closes, to improve the stability of the elastomer of preparation.
Step 4:
The precuring agent of 0.9kg epoxy is added in mixed solution into step 4, stirs 60min, mixing speed 50r/
Min, and it is 70 DEG C that reaction temperature is kept when stirring, so that epoxy precuring agent is uniformly mixed with very conjunction solution, is contracted
Water glyceride performed polymer is labeled as A liquid；
Step 5:
Further take out bis- generation of Grubbs catalyst 0.075g, glycidol rouge curing reaction promotor 0.35kg, the micro- glue of red phosphorus
Capsule fire retardant 8.350075kg is mixed and stirred for remaining 20kg dicyclopentadiene, realize it is evenly dispersed, and by the molten of formation
Liquid is labeled as B liquid；Wherein glycidol rouge curing reaction promotor is boron trifluoride and its complex compound, boron trifluoride and its complexing
Object is boron trifluoride, boron trifluoride methyl ether complex compound, boron trifluoride etherate, boron trifluoride-phenol complex, borontrifluoride
Boron n-butyl ether complex compound, boron trifluoride monoethyl amine complex compound, boron trifluoride piperidines complex compound, boron trifluoride-triethanolamine complexing
It is any in object, boron trifluoride acetic acid complex compound, boron trifluoride etherate is used in the present embodiment.
Step 6:
Injection molding after A liquid in step 4 and the B liquid in step 5 are mixed, it is poly- to form waste and old circuit board non-metal powder
Dicyclopentadiene elastomer.
Embodiment 2-6 the difference is that only that parameter as shown in Figure 1 is different from embodiment 1.
Non-metal powder is ground using grinding device, for waste and old circuit board non-metal powder polydicyclopentadiene bullet
Property body preparation, have the effect that 1, by setting Screening Network, can be realized the biggish non-metal powder screening of partial size
Out, progress is secondary grinds, and so as to ensure, makes the partial size of non-metal powder smaller preparing elastomer, therefore energy
The adhesive effect between other raw materials of enough old metal powder, so that the stability of the elastomer of preparation is high.
2, by the way that old metal powder is carried out secondary grinding, it can be improved the utilization rate of non-metal powder, reduce production bullet
