Embodiment 1

[0046] Embodiment 1: A kind of corrosion-resistant conductive rubber button, refer to figure 2 , including a base 1 and several key blocks 2 integrally formed on the base 1 , the side of the key block 2 away from the base 1 protrudes with identification characters 3 , and the side of the key blocks 2 away from the base 1 is located on the peripheral side of the identification characters 3 At least two layers of easy-to-tear sheets 4 are provided. In this embodiment, the number of layers of easy-to-tear sheets 4 is two layers, and the identification characters 3 protrude from the end wall of the outermost easy-to-tear sheet 4 .

[0047] refer to image 3 and Figure 4 The easy-to-tear sheet 4 includes an aluminum layer 401 on a side away from the base 1 and an anti-corrosion sealing layer 402 on a side close to the base 1, and the anti-corrosion sealing layer 402 includes an outer layer 4021 on a side close to the aluminum layer 401 and an outer layer 402 The inner layer 402...

Embodiment 2-4

[0056] Embodiment 2-4: A corrosion-resistant conductive rubber button. The difference from Embodiment 1 is that the components of the inner layer 4022 and the outer layer 4021 and their corresponding parts by weight are shown in Table 1.

[0057] Each component and parts by weight thereof in table 1 embodiment 1-4

[0058]

[0059]

Embodiment 5

[0060] Embodiment 5: A corrosion-resistant conductive rubber button. The difference from Embodiment 1 is that the melting point of paraffin wax in the raw material of the inner layer 4022 in this embodiment is 58°C.

[0061] The beneficial effects of the present invention are as follows: firstly, the identification characters 3 are protruding and can be directly injection-molded, which saves the spraying process and optimizes the production process of the rubber key; secondly, the easy-to-tear sheet 4 can be corroded or Torn off after wear and tear, so that the identification characters 3 are exposed again, ensuring the stability of the identification characters 3; moreover, the aluminum layer 401 is made of aluminum, has a certain hardness, and has good wear resistance; and the surface of the aluminum will A dense oxide film is formed, and the oxide film can play an anti-corrosion role; finally, the anti-corrosion sealing layer 402 can not only play a role in anti-corrosion, b...

Abstract

The invention discloses a corrosion-resistant conductive rubber key and a preparation method thereof, and relates to the technical field of rubber products. Technical key points are that: the key comprises a base and a key block, the side, away from the base, of the key block protrudes to form an identification character, at least two layers of easy-to-tear pieces are arranged on the side, away from the base, of the key block and located on the periphery of the identification character, each easy-to-tear piece comprises an aluminum layer away from the side of the base and an anti-corrosion sealing layer close to the side of the base, and the key has the advantages of abrasion resistance.

Description

technical field [0001] The invention relates to the technical field of rubber products, more specifically, it relates to a corrosion-resistant conductive rubber key and a preparation method thereof. Background technique [0002] Rubber refers to a highly elastic polymer material with reversible deformation, which is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. The nature of rubber makes it widely used in many fields, for example, rubber materials are widely used on the keys of controllers. [0003] An existing conductive rubber button, such as figure 1 As shown, it includes a base 1 made of rubber and several key blocks 2 integrally formed on the base 1 . The base 1 is located at the back of the rubber block and is bonded with a conductive block (not shown in the figure). During the installation process, it is sufficient to place the conductive rubber key ...
