Problems solved by technology

[0004] At present, the research and development of flame-retardant rubber materials is mainly concentrated in the fields of cables, rubber pipes, rubber floors, and interior materials of various vehicles. Since the above-mentioned materials themselves are black, the aging resistance of the materials under long-term sunlight is rarely involved. , and rarely consider whether the damping performance and hardness of the rubber material itself matches the acoustic requirements
At the same time, with the increasingly stringent environmental protection policies, many tradi

Abstract

The invention provides a flame-retardant high-damping rubber composition, a preparation method and application thereof. The rubber composition is a non-black rubber composition and comprises the following components in parts by weight: 80-100 parts of butyl rubber, 5-13 parts of a vulcanization system, 40-100 parts of a flame retardant, 4-12 parts of an antioxidant and 10-30 parts of a pigment. According to the invention, by screening the raw materials and compounding the components, the rubber composition has excellent flame retardancy and photooxidative aging resistance on the premise of ensuring the damping property and acoustic property; and the rubber composition is a safe and environment-friendly high polymer material, the flame retardant property of the rubber composition can reachthe V-0 level, no obvious color difference exists under ultraviolet irradiation, the use requirements of loudspeaker rubber edges can be fully met in the aspects of mechanical property, damping property, aging resistance, appearance color and the like, and the rubber composition has a good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a flame-retardant and high-damping rubber composition and a preparation method and application thereof. Background technique [0002] Commonly used rubber materials for speaker rubber edges include butyl rubber (IIR), nitrile rubber (NBR) and ethylene-propylene-diene rubber (EPDM), etc., whose oxygen index is less than 22, which is a flammable material. As a household appliance, the loudspeaker will generate heat during use, and occasionally short-circuit. Both the heating and short-circuit of the speaker may catch fire and cause safety accidents, threatening personal and property safety. Therefore, as an important part of the speaker, the use of flame-retardant rubber edges is imperative. In addition, with the diversified development of speaker application scenarios and application environments, new requirements have been put forward for the performance of...
