Low-friction-noise material, noise reduction master batch and preparation method thereof

Abstract

The invention provides a low-friction-noise material, a noise reduction master batch and a preparation method thereof. The noise reduction master batch comprises the following components in percentage by weight: 90-96% of a copolymer, 2-8% of hydrocarbon synthetic oil and 2-8% of silicone, wherein the copolymer is a block copolymer of butadiene or isoprene and styrene, the kinematic viscosity of the hydrocarbon synthetic oil at 40 DEG C is 300-400 mm < 2 > / s, and the silicone is solid. The low-friction-noise material is prepared from the following components in parts by weight: 65-90 parts of high-impact ABS (Acrylonitrile Butadiene Styrene), 5-15 parts of the noise reduction master batch, 2-8 parts of a wear-resistant agent, 3-18 parts of a soft rubber component, 0.1-1 part of an antioxidant and 0.1-1 part of a lubricant. The low-friction-noise material has an excellent low-stick-slip effect, so that the low-friction noise material has relatively low friction noise.

Description

technical field

[0001] The invention relates to the technical field of low-friction noise materials, in particular to a low-friction noise material, a noise reduction masterbatch and a preparation method thereof. Background technique

[0002] ABS or PC / ABS materials are more commonly used materials for lifting brackets of display devices, but the above materials will produce "squeak" noise due to friction during use. The current common solutions mainly include coating soft rubber materials, coating the surface with lubricating oil, and replacing the above materials with metal materials. The above methods can effectively reduce the frictional noise of the material, but the disadvantages are also obvious. The solution of covering the soft rubber material will increase the cost of the entire product. The scheme of coating lubricating oil will cause users to come into contact with lubricating oil when using the product, which will affect the user experience, and as time goes by...
