Embodiment 1

[0046] Such as Figure 1-9 As shown, an environmentally friendly flame-retardant conductive foam includes a conductive foam inner core 1, the outer periphery of the conductive foam inner core 1 is coated with a high-temperature resistant flame-retardant conductive elastic film 101, and the outer periphery of the high-temperature resistant flame-resistant conductive elastic film 101 is pasted with Copper-plated conductive cloth 102, the outer periphery of copper-plated conductive cloth 102 is coated with magnetic current layer 103, the outer periphery of magnetic current layer 103 is pasted with nickel-plated conductive cloth 104, and the outer surface of nickel-plated conductive cloth 104 is coated with an environmentally friendly water-based flame-retardant coating. Burning layer 105.

[0047] The high-temperature-resistant flame-retardant conductive elastic film 101 includes 10 parts of conductive metal nickel powder, 25 parts of type II ammonium polyphosphate (melamine-coat...

Embodiment 2

[0066] Because the spring is energized, the two ends of the spring generate magnetism. When the spring is pulled outward, because the end of the magnetic current layer 103 is affected by the magnetic field, the magnetic current layer 103 will be attracted by the spring, and the magnetic current layer 103 at both ends of the conductive foam will be lost. Product quality, in order to solve the problems referred to above, do following improvement on the basis of embodiment 1.

[0067] The left and right sides of the front side wall of the work box 2 are symmetrically provided with a second manipulator 16, and the second manipulator 16 includes two claw-type mechanical claws 1601, and the opposite sides of the two claw-type mechanical claws 1601 are provided with electrode sheets, and the second manipulator 16 passes through the The mechanical arm 1602 is connected with the output shaft of the rotating motor, and the rotating motor is fixedly connected with the front side wall of t...

Embodiment 3

[0072] Such as Figure 10 As shown, the preparation method of an environmentally friendly flame retardant conductive foam is prepared by using a preparation device for an environmentally friendly flame retardant conductive foam as provided in the second embodiment: the detailed preparation steps are as follows:

[0073] S1. Use the digital control spring preparation component 11 to wind a layer of memory alloy metal wire on the conductive foam inner core 1 to form a helical spring, so that the helical spring is pre-compressed on the conductive foam inner core 1;

[0074] S2. If Figure 9 As shown, by energizing and heating the spring at a distance from the right end of the conductive foam inner core 1 to the center L of the conductive foam inner core 1, while using the second manipulator 16 to straighten the energized spring; 1. The spring at a distance L from the left end to the center of the conductive foam inner core 1 is energized and heated, and the second manipulator 16...

Abstract

The invention relates to the technical field of conductive foam, and discloses an environment-friendly flame-retardant conductive foam. The conductive foam comprises a conductive foam inner core, the periphery of the conductive foam inner core is coated with a high-temperature-resistant flame-retardant conductive elastic film, copper-plated conductive cloth is adhered to the periphery of the high-temperature-resistant flame-retardant conductive elastic film, and the periphery of the copper-plated conductive cloth is coated with a magnetic current layer. According to the invention, the magnetic current layer is arranged between the copper-plated conductive cloth and the nickel-plated conductive cloth, the conductive foam can be bent in the transportation and pasting process, and the magnetic current layer has conductivity, so that the magnetic current layer is used for supplementing the conductivity of the coating falling part on the nickel-plated conductive cloth; and the magnetic shielding capability of the plating layer falling part is weakened due to the falling of the plating layer of the nickel-plated conductive cloth, and the magnetic current layer is in electric contact with the nickel-plated conductive cloth at the moment, so that the magnetic current layer and the nickel-plated conductive cloth which does not fall off jointly form a shielding body, and the situation that the conductivity and the magnetic shielding capability are weakened due to the falling or damage of the nickel-plated conductive cloth is avoided.

Description

technical field [0001] The invention relates to the field of conductive foam, in particular to an environmentally friendly flame-retardant conductive foam. Background technique [0002] Conductive foam is made of conductive fiber cloth with low compression force lining. The most important thing about conductive foam is its shielding performance and conductivity. The shielding performance can effectively shield electromagnetic waves and prevent external Electromagnetic interference and emission of radiation. Conductivity can play the role of electrostatic protection, such as connecting the grounding point of the circuit board and the metal shell or components, so as to achieve the consistency of the system ground potential and reduce the electromagnetic radiation of the circuit board; discharge the ESD static electricity of the screen and keyboard of the mobile phone and notebook Put it on the grounding line of the product, so as to improve the antistatic ability of the prod...
