Accompanying drawing explanation
accompanying drawing 1 is the structural representation of the transversal profile of high conductive elastomer one specific embodiment in the present invention.
Embodiment
below in conjunction with accompanying drawing and specific embodiment, technical scheme of the present invention is further elaborated.
a kind of high conductive elastomer as shown in Figure 1, this elastomerics comprises sponge matrix 1, on sponge matrix 1, there are a plurality of through hole (not shown)s that run through mutually up and down, on the vestibule wall of above-mentioned through hole, plating is provided with metal conducting layer 2, on metal conducting layer 2, have at least part to expose the outside, two ends at above-mentioned through hole, on the outer surface of metal conducting layer 2, be also coated with and solidify glue-line 3, the upper surface of sponge matrix 1, between lower surface, have at least and on a surface, be provided with successively from the inside to the outside conductive adhesive layer 4, off-style paper layer 5, during use, tear off-style paper layer 5 off and just can this elastomerics be affixed to specified location by conductive adhesive layer 4.This elastomeric structure makes it have good viscosity, flexibility, elasticity and compressibility, in use procedure, be difficult for being torn and there will not be the phenomenon powdering away, and in its use procedure, can make completely to fill completely between electronic component and transfer surface, to reach sufficient contact, make its upper and lower conducting, thereby also there is good electroconductibility.
the making processes of this high conductive elastomer is as follows:
first select foam sponge as starting material, this foam sponge can be the material foaming such as polyester, polyethers, polyolefine and forms, and it has a plurality of through holes that run through up and down, cuts the part of specified size as sponge matrix 1 on foam sponge; Then to sponge matrix 1 plated metal, the molten metal that makes to electroplate is attached on the vestibule wall of through hole and forms metal conducting layer 2, and makes metal conducting layer 2 have part to expose the outside at through hole.After plating completes, upper at sponge matrix, glue that can be curing on being coated with equably on lower surface, this glue can adopt mass percent to be respectively 5～95% raw-silastic continuously, 1～30% silane coupling agent, 1～30% organo-peroxide and 5～10% mill base is mixing obtains, the thickness that glue covers in sponge matrix 1 upper and lower surface is 5%～70% of sponge matrix 1 thickness, treat that glue permeates in the through hole vestibule of sponge matrix 1 completely, glue covers on the outer surface of metal conducting layer 2, after solidifying, on the surface of metal conducting layer 2, form and solidify glue-line 3, after glue curing, again sponge matrix 1 is carried out to pressing and forming, make the part of exposing through hole outside on metal conducting layer 2 when pressing, puncture curing glue-line 3 and expose outside curing glue-line 3, after pressing and forming, at normal temperature 12～48 hours or 50～100 ℃, 8～24 hours after fixing glue-lines 3 are completely curing again, so just, can obtain required high conductive elastomer.Finally can in the upper and lower surface of the above-mentioned high conductive elastomer obtaining, paste according to user's demand conductive adhesive layer 4 and off-style paper layer 5.This production method is simple, environment friendly and pollution-free in production process, and production cost has obtained effectively reducing.
