Abstract
The utility model provides novel multifunctional material, which not only has the functions of electrostatic protection and electric conduction, but also has the effect of electromagnetic shielding with as high as 60-80dB decrement. The utility model has the advantages of simple moulding process, strong adhesion of electric conductive material, long safety action, proper cost, notable preventing function and no invalidation.
Description
The utility model belongs to electromagnetic compatibility and guard technology field, is to be used for electrostatic defending, electromagnetic shielding and the multi-functional material of conduction.
At present, the material that is used for electrostatic defending both at home and abroad is to add antistatic agent at common material, conductive material or metallic fiber inweaved in the general fabrics.Utilize antistatic agent, electric conducting material and metallic fiber to play and prevent generation of static electricity and summation.The material that is used for electromagnetic shielding then is directly to adopt metal forming materials such as metallic plate, wire netting; Or at general material surface spraying one deck electrically-conducting paint; In general fabrics, add method formation conductive barriers such as ultrafine metal fibers, play electromagnetic shielding action.
But above-mentioned material all exists many problems and defective to some extent.Add the volatile inefficacy of antistatic agent material; Add the conductive material complex process, the cost height; Surface spraying conductive coating paint cost height, poor adhesive force; Metal forming material cost is high, take the useful space, the packaging technology complexity, and the process-cycle is long.
Purpose of the present invention provides a kind of novel existing antistatic protection function, conducting function; Has multifunctional fabric again up to the electromagnet shield effect of 60-80dB attenuation.This forming materials technology is simple; The conductive material strong adhesion; Protective action is lasting, does not lose efficacy; Cost is moderate, and safeguard function is remarkable.
The present invention seeks to be achieved through the following technical solutions.Can select fabric for use, as base material, then the substrate surface layer is handled totally, adopted methods such as chemical coated method, vacuum coating to make two surfaces or the high film of lip-deep even coated one deck conductance of base material at last, can become antistatic, electromagnetic shielding multifunctional fabric.Utilize the high conductivity rete that firmly is bonded on the substrate surface to play antistatic, the multiple function of electromagnetic shielding.High conductivity rete Main Ingredients and Appearance is silver, nickel, zinc, copper, ferrous metal material.
A kind of example of utility model is described below in conjunction with accompanying drawing 1.
Accompanying drawing 1 is antistatic, electromagnetic shielding multifunctional fabric structural representation.
Selecting pure polyester fabric for use is base material 1
The first step is cleaned oil removing;
The activation of second step was handled 5 minutes with palladium bichloride, stannous chloride, activating solution;
The 3rd step alkali treatment was handled 5 minutes with caustic lye of soda;
The 4th step rinsing;
The 5th step chemical plating.
Prescription: nickelous sulfate (400g/L) 5%
Ammonium chloride (200g/L) 10%
Natrium citricum (200g/L) 5%
Inferior sodium phosphate (600g/L) 5%
Activating agent 0.01%
Just can obtain high conductivity rete 2 by above five steps.
The 6th step face coat 3 is with polyvinyl alcohol coating back oven dry.
Claims (2)
1, a kind of antistatic, electromagnetic shielding multifunctional fabric is characterized in that, the surface of base material coated equably has the conductive film layer of high conductivity.
2,, it is characterized in that base material can use yarn fabric, nonwoven fabrics according to described antistatic, the electromagnetic shielding multifunctional fabric of claim 1.
