Abstract

The invention discloses a flame-retardant vibration reduction and sound insulation material which comprises the following components in parts by weight: 90-120 parts of butyl rubber, 5-15 parts of ethylene propylene diene monomer, 20-30 parts of petroleum resin, 150-180 parts of aluminum hydroxide, 40-60 parts of expanded graphite and 35-55 parts of zinc borate. The flame-retardant vibration reduction and sound insulation material disclosed by the invention has the advantages of being highly flame retardant, environmental-friendly, excellent in damping and sound insulation performances, wide in applicable temperature range, aging-resistant and the like and can be applied to the field of automobile industry. Moreover, the invention further provides a preparation method of the flame-retardant vibration reduction and sound insulation material.

Description

technical field [0001] The invention relates to a sound-insulating material and a preparation method thereof, in particular to a flame-retardant, vibration-reducing and sound-insulating material and a preparation method thereof. Background technique [0002] The damping and vibration-absorbing material has the functions of vibration and noise reduction. The vibration and noise of automobiles are related to environmental protection, the stability, durability and safety of automobile operation. Foreign countries have long adopted low-cost asphalt-based materials to effectively prevent and control the noise in the automobile interior. However, as people's awareness of environmental protection gradually increases, the requirements for environmental protection in automobile interiors gradually increase, and asphalt-based vibration-damping materials are gradually replaced by rubber materials. [0003] Butyl rubber is an excellent damping material. The material can be applied to ...
