Technical field
The present invention relates to conductive rubber and preparation conductive rubber used silvered glass fiber, be specially a kind of silvered glass fiber preparation method and utilize the conductive rubber of this silvered glass fiber production.
Background technology
In recent years; Conductive rubber has been widely used in the aspects such as pressure sensitive in electromagnetic shielding material, antistatic material, PTC material and the touch controls switch; Its Application Areas has spread all over automobile, aircraft, electrical equipment, computingmachine, national defence, military affairs, space flight, building, medical treatment, food etc. and the people closely bound up industry of living, and growth of the national economic is played crucial effect.Wherein, with regard to conductive rubber, owing to combine high conductivity and the peculiar constructional feature of rubber itself, it is bringing into play irreplaceable effect in the electromagnetic shielding field with regard to electromagnetic shielding material.
Conductive filler material is the functive of conductive rubber, and the conductivity of conductive rubber is played a leading role.Generally speaking, this functive mainly is divided into the carbon series conductive filler and metal is two types of conductive filler materials.For carbon system; Traditional carbon black and graphite can't have been given the sufficiently high conductivity of rubber and realize electromagnetic shielding; Even if also can't satisfy the needs of high shielding properties with the conductive rubber of the good acetylene carbon black of conductivity or conductive carbon black preparation, particularly, can cause the frangible and layering of rubber unvulcanizate because graphite has self-lubricating function; Not only influence the technology and the mechanical property of material, the conductivity of its product is also very unstable.De-carbon is outside the filler, and it is silver powder, silver-plated copper powder, silver-plated nickel powder etc. that conductive rubber material is used maximum conductive filler materials, and there are subject matters such as density is big, cost height in such filler.In addition, also have with the silvered glass microballon and do conductive filler material, but its mechanical property is undesirable.
Spun glass has more significant advantage with its bigger length-to-diameter ratio aspect the rubber strongthener, it overlaps in rubber matrix each other, more be prone to form conductive network with respect to glass microballon, copper powder, nickel powder etc., and its mechanical property is also better relatively.
Existing metallic conduction packing density is big, cost is high; Can't satisfy the hyundai electronics industrial expansion; But also do not have at present a kind of good will the nonmetal and stable conductive filler material of metallic substance bonded chemical property; Especially also there is not a kind of advantage of effectively utilizing spun glass and metallic conduction filler, with the technology of the two good combination as conductive filler material.
Summary of the invention
Existing metallic conduction packing density is big, cost is high in order to solve in the present invention, can't satisfy the problem of hyundai electronics industrial expansion, and a kind of silvered glass fiber preparation method is provided and has utilized the conductive rubber of this silvered glass fiber production.
