Power plant rice hull ash/nitrile butadiene rubber composite magneto-rheological elastic material and preparation method thereof

Abstract

The invention discloses a power plant rice hull ash / nitrile butadiene rubber composite magneto-rheological elastic material. The power plant rice hull ash / nitrile butadiene rubber composite magneto-rheological elastic material is prepared from the following raw materials in parts by weight: 60 to 80 parts of nitrile butadiene rubber, 140 to 190 parts of tetrahydrofuran, 48 to 68 parts of maleic anhydride, 2 to 5 parts of benzoyl peroxide, a proper amount of ethanol, 2 to 4 parts of sodium hypophosphite hydroxide, a proper amount of xylol, 25 to 37 parts of softwood cellulose, 1 to 2 parts of stearic acid, 1 to 5 parts of carbon black, 1 to 2 parts of sulfur, a proper amount of de-ionized water, 1 to 3 parts of triethanolamine, 2 to 9 parts of nickel powder, a proper amount of 6mol / L NaOH water solution, 2 to 7 parts of tetrabutyl titanate, 4 to 9 parts of power plant rice hull ash and 2 to 4 parts of wheat hull. According to the power plant rice hull ash / nitrile butadiene rubber composite magneto-rheological elastic material, the nitrile butadiene rubber is grafted by the maleic anhydride and then is grafted and compounded with the softwood cellulose, so that the damping performance, and sound absorption and noise reduction performances of the material are enhanced; meanwhile, a nitrile butadiene rubber based magneto-rheological elastic material prepared by adding metal particles which are covered by titanium dioxide and have nickel kernel-shell strucutres, is controllable in damping performance; the material can be applied to the fields of vibration absorption, noise reduction and the like.

Description

technical field [0001] The invention belongs to the field of automobile parts preparation, and in particular relates to a power plant rice husk ash / nitrile rubber composite magnetorheological elastic material and a preparation method thereof. Background technique [0002] Damping material is a kind of shock-absorbing and noise-reducing material developed in recent years. It can convert vibration and sound energy into heat energy and dissipate new functional materials. It is widely used in various mechanical equipment, especially in the front of the car passenger compartment. There are 8-12 parts such as hoardings, car doors, car roofs, car floors, and trunks. Commonly used damping materials generally reduce vibration by storing and consuming vibration energy by themselves, lacking self-regulation capabilities. For this reason, a smart damping material with good controllability and nonlinear characteristics is urgently needed. [0003] Magnetorheological materials are a clas...
