Abstract

The invention discloses a temperature-insensitive high-damping elastic gumming dirt buffering material and a preparation method thereof, which relate to an elastic gumming dirt damping buffer material. The temperature-insensitive high-damping elastic gumming dirt buffering material comprises the following components in parts by weight: 100 parts of silicon rubber, 1-10 parts of methyl silicone oil serving as a viscosity modifier, 0.1-2 parts of a compression resisting agent, 0.5-10 parts of a filler, 0.5-5 parts of carbon black serving as a reinforcing agent, 0.1-1 part of dioctyl adipate (DOA) serving as a cold-resistant plasticizer, 0.5-5 parts of hydrogen-containing silicon oil serving as a softening agent and 1-10 parts of a side-chain polysiloxane liquid crystal elastomer, wherein the liquid crystal elastomer contains 4-(omega-acrylate ethyoxyl ester group)benzoyloxy-4'-benzoic acid smectic liquid crystal element (M) and a di-4-(para-allyloxy)benzoyloxy-4'-butyl benzoate (N) smectic liquid crystal crosslinking agent. Due to the adoption of the temperature-insensitive high-damping elastic gumming dirt buffering material, the elasticity, order and liquidity of gumming dirt are improved, and the use requirements of a high-absorbing-power gumming dirt buffer are met.

Description

technical field [0001] The invention relates to an elastic mastic buffer material, in particular to a temperature-insensitive high-damping elastic mastic buffer material, and also relates to a preparation method of the mastic buffer material. Background technique [0002] my country's research on elastic cement and its shock absorbers began in the 1990s, and the current research level is still relatively low, and the production of shock absorbers has just started. [0003] Among the various buffers currently used, the elastic cement buffer is the most ideal product for absorbing impact energy. It has the advantages of large capacity, small resistance, small size, light weight, and long maintenance cycle. It is mainly used in military industries and industrial buildings. , bridge, port machinery and other industries. The medium used in the elastic cement buffer is elastic cement, which has elasticity, compressibility and fluidity, and has the advantages of both hydraulic buf...
