preparation example Construction

[0036] A kind of preparation method of the anti-EMI silica gel liner that directional wire fills, it may further comprise the steps:

[0037] 1) Metal wire pre-treatment: degrease the metal wire and treat the surface with silane coupling agent or titanate coupling agent;

[0038] 2) Uniform wire distribution: the metal wire is evenly wound on the rectangular metal frame, the wire-wrapped metal frame and the non-wire-wrapped metal frame are pressed together at intervals, and the mold cavity is sealed with a sealant;

[0039] 3) Glue injection: defoam the liquid glue in a mixer, then fill the membrane cavity, and place the cavity in a vacuum defoaming machine for defoaming;

[0040] 4) Vulcanization molding;

[0041] 5) Cutting: Cut rubber sheets of various thicknesses according to customer needs, and the cutting direction is perpendicular to the direction of wire arrangement.

[0042] Wherein, in step 1, the surface of the wire is cleaned with a silane coupling agent or a tit...

Embodiment 1

[0046] Such as figure 1 and figure 2 As shown, this embodiment is an anti-EMI silicone gasket filled with directional wires, which includes a silicone body 1 , and metal wires 2 are oriented and evenly distributed in the silicone body. The metal wire 2 is a Monel wire with a wire diameter of 0.15 mm and pressed into a sinusoidal shape.

[0047] Among them, the peak height of the sinusoidal Monel wire is 0.2 mm.

[0048] The preparation method of the anti-EMI silica gel liner that above-mentioned directional wire fills may further comprise the steps:

[0049] 1) Monel wire pre-treatment: Press the Monel wire into a sinusoidal shape, and treat the surface with a silane coupling agent after degreasing to ensure sufficient adhesion between the metal wire and the rubber;

[0050] 2) Uniform wire distribution: Wind the Monel wire evenly on the rectangular metal frame, press the wrapped metal frame and the non-wired metal frame at intervals, and seal the outside of the mold cavit...

Embodiment 2

[0056] Such as figure 1 and figure 2 As shown, this embodiment is an anti-EMI silicone gasket filled with directional wires, which includes a silicone body 1 , and metal wires 2 are oriented and evenly distributed in the silicone body. The metal wire 2 is a Monel wire with a wire diameter of 0.1 mm and pressed into a sinusoidal shape.

[0057] Among them, the peak height of the sinusoidal Monel wire is 0.05mm

[0058] The preparation method of the anti-EMI silica gel liner that above-mentioned directional wire fills may further comprise the steps:

[0059] 1) Monel wire pre-treatment: Press the Monel wire into a sinusoidal shape, and treat the surface with a silane coupling agent after degreasing to ensure sufficient adhesion between the metal wire and the rubber;

[0060] 2) Uniform wire distribution: Wind the Monel wire evenly on the rectangular metal frame, press the wrapped metal frame and the non-wired metal frame at intervals, and seal the outside of the mold cavity wi...

Abstract

The invention provides a directional metal wire-filled anti-EMI silica gel liner and a preparation method thereof. The directional metal wire-filled anti-EMI silica gel liner comprises colloidal silica, and the metal wire is directly and uniformly distributed in the colloidal silica. The provided anti-EMI silica gel liner has high elasticity as common rubber, and has conductive reliability of metal material.

Description

technical field [0001] The invention relates to the field of anti-EMI technology, in particular to an anti-EMI silica gel gasket filled with directional wires and a preparation method thereof. Background technique [0002] Electromagnetic Interference (EMI for short) refers to the interference phenomenon caused by the interaction between electromagnetic waves and electronic components. There are two types of conducted interference and radiated interference. Conducted interference refers to the coupling (interference) of a signal on one electrical network to another electrical network through a conductive medium. Radiation interference refers to the interference source coupling (interference) its signal to another electrical network through space. With the development of the electronics industry, electromagnetic radiation is ubiquitous, which not only affects the environment, but also causes harm to human health, and seriously affects the normal operation of electronic equip...
