Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rubber pads, in particular to a green and environmentally friendly halogen-free and sulfur-free rubber pad for preventing static electricity and a preparation method thereof. BACKGROUND

[0002] The anti-static rubber pad is often used for placing electronic devices thereon, and the anti-static rubber pad can effectively dissipate static electricity to avoid the generation of static electricity. The rubber pad is soft and is easily damaged due to extrusion deformation when being pressed by a heavy object for a long time. In order to prevent the electronic product from sliding on the rubber pad, a concave-convex structure is usually arranged on the surface of the rubber pad to prevent slipping.

[0003] The existing rubber pad has the following defects:

[0004] 1. The prior art KR1020140025210A discloses a rubber pad, which does not have the function of improving the compression resistance of the rubber pad. The rubber pad is easily deformed and damaged when being pressed by a heavy object for a long time, which affects the service life. Therefore, a green and environmentally friendly halogen-free and sulfur-free rubber pad for preventing static electricity is needed to solve the problem, which can improve the compression resistance of the rubber pad and prolong the service life under pressure.

[0005] 2. The prior art KR1020040029600A discloses a rubber pad. When a concave-convex structure is arranged on the rubber pad to increase the anti-slip ability, the concave part of the concave-convex structure is easy to accumulate dust, and it is not easy to clean the dust in the concave part. Therefore, a green and environmentally friendly halogen-free and sulfur-free rubber pad for preventing static electricity is needed to solve the problem, which can prevent slipping and facilitate cleaning of the concave-convex part.

[0006] 3. The prior art JP2005257002A discloses a rubber pad. If a concave hole is provided on the rubber pad to place a supporting block, water is easy to accumulate in the concave hole, and long-term contact of rubber with water can cause adverse effects on the performance of the rubber. Therefore, a green and environmentally friendly halogen-free and sulfur-free rubber pad for preventing static electricity is needed to solve the problem, which can provide a concave groove and avoid water accumulation in the concave groove to cause corrosion of the rubber pad.

[0007] 4. The prior art CN111909469B discloses a long-acting anti-static rubber pad. The technology does not have the function of preventing the accumulation of heat generated by electronic products thereon. The electronic products are easy to accumulate heat on the contact surface when working on the rubber pad for a long time, which has adverse effects on the electronic products and the rubber pad. Therefore, a green and environmentally friendly halogen-free and sulfur-free rubber pad for preventing static electricity is needed to solve the problem, which can dissipate the heat on the contact surface of the electronic products and the rubber pad.
