Embodiment 1

[0042] Please refer to figure 1 , the present embodiment provides a preparation process of automobile stripe sound-absorbing sheet 100, which includes the following steps:

[0043] S1, coating the rubber solution on one side of the metal plate base material 10 to form a rubber layer 11 superimposed on the metal plate base material 10, and the rubber layer 11 and the metal plate base material 10 cooperate with each other to form a metal composite plate;

[0044] S2, vulcanizing the metal composite board to obtain a vulcanized metal composite board;

[0045] S3, rolling, brushing or dip-coating the graphite-based resin coating on the vulcanized metal composite plate, and disposing the graphite-based resin coating on the rubber layer 11 in stripes to obtain the anti-scratch layer 12 .

[0046] The preparation process of the automobile stripe sound-absorbing sheet 100 can process a stripe-shaped graphite-based resin coating on the rubber layer 11, so that the prepared automobile-...

Embodiment 2

[0057] Please refer to figure 2 and image 3 , this embodiment provides an automobile stripe sound-absorbing sheet 100 prepared by the above-mentioned preparation process. The automobile stripe sound-absorbing sheet 100 comprises a metal plate base material 10, a rubber layer 11 and an adhesive layer 13, and the rubber layer 11, the metal plate base material 10 and the adhesive layer 13 are laminated in sequence, and the rubber layer 11 is provided with Stripe-shaped scratch-resistant layer 12 . It is worth noting that the sound is produced by vibration. The noise during braking is produced by the frictional vibration between the friction pad and the brake disc or brake drum. Only the sound of a certain frequency can attract people's attention. One of the components, it is mainly composed of brake lining (friction material part) and rigid back (metal part), the sound wave will change once from the friction lining to the rigid back, and from the rigid back to the metal plate...

Abstract

The invention provides an automobile stripe silencing sheet and a preparation process, and relates to the technical field of silencing sheet production. The preparation process comprises the following steps: S1, coating one side of a metal plate base material with a rubber solution, and forming a rubber layer overlapped with the metal plate base material, wherein the rubber layer and the metal plate base material are matched with each other to form a metal composite plate; s2, vulcanizing the metal composite plate to obtain a vulcanized metal composite plate; and S3, roll coating, brush coating or dip-coating a graphite-based resin coating on the vulcanized metal composite plate, and arranging the graphite-based resin coating on the rubber layer in a striped manner to obtain the anti-scratching layer. According to the preparation process, the striped graphite-based resin coating can be processed on the rubber layer,so that the prepared silencing sheet has an anti-scratching effect, the metal composite plates are prevented from being stacked together in the product stamping process, burrs on the edges of a friction product are prevented from scratching the surface of the product in the packaging process, and the final forming quality of the product is improved. The silencing sheet is prepared by the process and has all the beneficial effects.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing sheet production, in particular to an automobile-striped sound-absorbing sheet and a preparation process. Background technique [0002] Car brake pads, also called brake shoes, are consumables that will gradually wear out during use. When the wear reaches the limit, they need to be replaced in time, otherwise the braking effect will be reduced, and even safety accidents will be caused. . The car stripe noise reduction sheet and the car brake pad cooperate with each other, and its main function is to reduce the noise during the friction process. [0003] During the processing process of the existing sound-absorbing sheets, it is easy for the base materials of the sound-absorbing sheets to overlap each other or rub against the burrs on the packaging before stamping and forming, resulting in scratches on the surface and affecting the quality and use effect of the sound-absorbing sheets.
