Abstract

The invention discloses a novel anticorrosive flame-retardant high-damping rubber material and a preparation method thereof. The novel anticorrosive flame-retardant high-damping rubber material comprises the following raw materials: high-phenyl silicone rubber, polyether 2000, low-functionality polyisocyanate, an acrylic polymer, an isocyanate prepolymer, a damping filler, an organic preservative,a coupling agent, a silicon-nitrogen flame retardant and other additives; and the preparation method provided by the invention comprises the following steps: (1) milling; (2) mixing; and (3) millingand then vulcanizing. The novel high-damping rubber material prepared in the invention has excellent damping performance, a compound loss rate being greater than 0.25 at different frequencies, and a wide damping temperature range.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a new anti-corrosion, flame-retardant and high-damping rubber material and a preparation method thereof. Background technique [0002] Damping materials use the viscoelastic properties of organic polymer materials to convert the vibration mechanical energy of sound waves into thermal energy and dissipate them, so as to achieve the purpose of reducing amplitude, reducing vibration and suppressing noise. High damping rubber has gradually been paid attention to in domestic bridge design due to its pollution-free and low cost. However, the glass transition temperature of rubber is generally much lower than room temperature, and the use of rubber blending to improve the performance of damping materials is limited, and the service life of damping materials can be improved. , extending its service life and improving its loss factor are common pursuits in the development and applic...
