Description
Technical field
The present invention relates to synthetic leather technical field, specifically a kind of production of the microfiber leather with electric conductivity
Method.
Background technology
As world market is more and more tighter to the resistance of animal leathercraft and environmental regulation, microfiber leather is because producing environmental protection no
The indexs such as pollution, content of beary metal can reach the requirement of European Union, and increasing travelling trader begins to use micro fiber leather to replace corium to answer
For high-end product.Microfiber leather is mainly made up of chemical fibre, and ultra-fine nylon fiber simulates corium in composition with configuration aspects
Collagen fabric, its line density and its distribution closer to natural leather, because its excellent performance is provided with super fiber leather
Outward appearance and immanent structure similar to corium, and microfiber leather base fabric adopts superfine fibre, elasticity is good, intensity height, soft,
Good permeability, many physical properties of high-grade synthetic leather have substantially exceeded natural leather, therefore at present microfiber leather Labor protection shoes,
The production fields such as sofa leather, automotive seat, safety and industrial gloves are used widely.With the raising of market demands, for super
The feature of fine leather has higher and higher requirement, in specific working space（Oil depot, explosives magazine and Petrochemical Enterprises etc.）Right
Its function has special requirement, and the characteristic due to chemical fibre easily produces electrostatic when friction phenomenon occurs, when electrostatic is accumulated
When tiring out a certain amount of, the accident such as burning and blast can be caused in high-risk environment.
Content of the invention
The present invention proposes a kind of production method of the microfiber leather with electric conductivity.
The technical scheme is that and be achieved in that：A kind of production method of the microfiber leather with electric conductivity, its
It is characterised by, comprises the following steps：
1）The spinning of composite fibre：Islands-in-sea bicomponent fibre, fabric of island-in-sea type are spun out as raw material with nylon 6 and Low Density Polyethylene
Island group in composite fibre is divided into nylon 6, and sea component is Low Density Polyethylene；
2）There is the making of the mixed type non-woven fabrics of conductive feature：With step 1）Made islands-in-sea bicomponent fibre with angstrom gram
Conductive fiber mix homogeneously produces the non-woven fabrics of average grammes per square metre 500-800g/ through needling process；Add an angstrom gram conductive fiber
Purpose be to allow conductive fiber form chain structure in non-woven fabrics, electronic energy is reached by the chaining channel movement in non-woven fabrics
To conductive characteristic.
3）The sizing of non-woven fabrics：To step 2）Obtained nonwoven heating, and by roll, which is shaped；Sizing is thick
Degree control is in 1.8-2.8；
4）Prepare the polyurethane resin working solution with electric conductivity：Dimethylformamide is initially charged in dispensing work kettle
（DMF）, add defoamer and stir, stir after being subsequently adding conductive black, be eventually adding polyurethane resin and stir；
The addition mass ratio for controlling dimethylformamide, defoamer, conductive black and polyurethane resin is 130-140:1-2:38-42：
380-420, the solid content for making polyurethane resin working solution is 23-26%, and viscosity is 11000-11300cps/30 DEG C；Described herein
The MP90E polyurethane resin that produces for Hua Da Chemical Co., Ltd. of polyurethane resin；
5）Impregnation tandem rolling of the polyurethane resin working solution to non-woven fabrics：Through step 3）Non-woven fabrics after process, then pass through containing step
Rapid 4）In the impregnating groove of the obtained polyurethane resin working solution with electric conductivity, during impregnation, while by multipair
Roll forces polyurethane resin working solution in press-in non-woven fabrics, and the gap between roll is（Cloth thickness -0.3mm）~（Cloth thickness-
0.2mm）；Realize the accurate quantification of polyurethane resin working solution, it is ensured that the stability of product quality；Pressure rolling is forced by roll,
Polyurethane working solution is passed in and out in non-woven fabrics repeatedly, is reached impregnation and is enriched uniform purpose, and control resin impregnated amount is in gross weight
50 or so percent；Carbon black conductive mechanism is to form tunnel-effect when white carbon black is uniformly distributed in polymer, and white carbon black exists
Assume seriality dispersion in polyurethane, the tunnel formed by white carbon black by electronics is transmitted and is moved through electric current, electric conductivity be by charcoal
The tunnel of black track producing particle determines.Fiber is by chain structure conduction, and resin bed is by tunnel structure conduction, the structure of dual pathways conduction
Ensure that persistency and the weatherability of conducting function, it is ensured that lifelong conductive capability.
6）Wet type solidification is carried out to polyurethane：Non-woven fabrics after impregnation enter coagulating basin and carry out wet type solidification, and the step is used
Water displaces the DMF in working solution, to reach the effect of urethane cures of allowing.
7）Toluene decrement treatment.
8）Expanding dried.
As preferred technical scheme, step 1）Described in nylon 6 and Low Density Polyethylene mass ratio be 50: 50-60:
40, double-component composite short fiber is produced using miscible spin processes, its fiber number is that 5 Denier, length is 51 millimeters.Nylon and poly- second
Alkene can be obtained the product of different hardness in different ratio blending, meet the characteristic of different product.
As preferred technical scheme, step 2）Described in mixed type conductive non-woven fabrics processing technology parameter request be pin
