Embodiment
In conjunction with embodiment, the present invention is further described：
Case study on implementation 1：
A kind of preparation method of the good graphene conductive yarn of ductility, comprises the following steps：
1）By 1Kg'sConcentration 5mg/mlGraphene dispersing solution and 50Kg nylon-66 plastics particle add double screw extruder and carry out
It is miscible to obtain immiscible material, make graphene dispersing solution during heating, miscible homogeneous is into immiscible material；
During miscible, to strengthen the electric conductivity of conductive yarn, step is added by graphene dispersing solution again, in immiscible material
Add 1Kg graphene dispersing solutions again and proceed miscible, obtain the miscible of the concentration 5mg/ml concentration graphene dispersing solutions containing 2Kg
It is 0.2% that thing, i.e. graphene account for total weight ratio in immiscible material.（Calculate this it is last it is miscible after percentage by weight because
It is that with the addition of dispersion liquid twice, its total amount should there was only 10g graphenes in 2+50KG, that 2KG, is based on 10g/50KG progress
Calculate, or 10g/52KG is calculated, it is not clear that and the liquid in dispersion liquid in addition to graphene can or can not be vapored away.）
2）Miscible extrusion yarn material is carried out by double screw extruder, yarn material is reeled off raw silk from cocoons by yarn pulling machine be fabricated to conduction again
Yarn.
3）The conductive yarn also passes through silver-plated process after reeling off raw silk from cocoons, and increases the antibiotic property of conductive yarn.
1）In step, the double screw extruder graphene dispersing solution is added with nylon-66 plastic particle by feeding mouth
Material, progress heating is miscible, stirs and is extruded into raw material, raw material is reeled off raw silk from cocoons by yarn pulling machine be fabricated to the conductive yarn again.
Because the concentration of graphene dispersing solution only has 5mg/ml, step progress can be added again by multiple graphene dispersing solution
Control the content of graphene in raw material so that the content of graphene in the feed meets production requirement.
The graphene dispersing solution is high due to itself denseness, and miscible with the progress of nylon plastic grains, is squeezed using single screw rod
Go out machine and be stirred the uneven or phenomenon that is fixed up occurs, it is necessary to use double screw extruder.
The present embodiment uses engagement type parallel dual-screw extruding machine, there is common flight element, reverse-flight elements, kneading
Block, toothed disc, S types element, six prism elements；The screw channel of intermeshing co-rotating twin-screw is non-close structure, and itself is conducive to material
Circulation mixing, after material is from charge door to a screw rod, in the case where friction is pulled, advances to lower section narrow along the screw channel of this root screw rod
Gap, another screw rod is held up after necessarily being compressed, and barrel surface another screw channel of frictional drag lower edge forward
Conveying, when material proceeds to top narrow gap, repeats this process, simply moves certain distance in the axial direction again, because
This, material be around two screw rods be spiral " ∞ " shape flowing.In addition, will be made in region of engagement material by the partial cut of strength
With along with the leakage current produced by the gap existed between screw rod between screw rod and machine tube inner wall, producing intermeshing twin-screw in the same direction
Raw good mixed effect.Further, since speed of two screw rods of meshing co rotating twin screw extrusion in region of engagement gap location
In the opposite direction, it causes there is more excellent mixed effect in region of engagement gap location.In meshing co rotating twin screw extrusion process
In, motion of the one root screw rod relative to another screw rod is to do translation, therefore any place two screw rods in its region of engagement around other side
Relative velocity it is all identical, therefore material bears substantially uniform constant shear rate in region of engagement so that the mixing of generation more becomes
Uniformly.
The yarn material extruded by double screw extruder, according to tradition reel off raw silk from cocoons technique be made conductive yarn, the conductive yarn
Increase its antibiotic property by conventional silver-plated process again.
Wire yarn made from the implementation case is solution formula conductive yarn, with being adhered in conventional art by conductive material
Conductor wire in wire body top layer is different, and the conductive yarn of the implementation case is not in scratch or top layer in any production process
The phenomenon of the influence electric conductivity such as conductive material disengaging, graphene is combined together with yarn, except the more preferable extension of offer
Property outside stronger electric conductivity is also provided, it is applied widely, be applicable to the field such as intelligent clothing and intelligent yarn fabric.
