Automobile high oil resistant chemigum elastic material based on magnetorheology and preparing method thereof

Abstract

The invention discloses an automobile high oil resistant chemigum elastic material based on magnetorheology. The material is prepared from, by weight, 63-80 parts of chemigum, 147-190 parts of tetrahydrofuran, 51-67 parts of maleic anhydride, 2-5 parts of benzoperoxide, a proper amount of ethyl alcohol, 1-4 parts of hydroxide sodium hypophosphite, a proper amount of xylene, 32-38 parts of softwood fibre, 1-2 parts of stearic acid, 3-6 parts of carbon black, 1-2 parts of sulphur, a proper amount of deionized water, 1-3 parts of triethanolamine, 3-8 parts of nickel powder, a proper amount of 6 mol / L NAOH aqueous solution, 2-6 parts of tetrabutyl titanate, 1-2 parts of methyl di (2-thienyl) glycolate, 0.5-1 part of ethlenethiourea and 1-2 parts of magnesium oxide. According to the automobile high oil resistant chemigum elastic material based on magnetorheology, maleic anhydride is subjected to grafting with chemigum and is subjected to grafting and compounding with softwood fibre afterwards, strengthening the damping capacity and the sound absorption and noise reduction performance of the material. Meanwhile, the damping capacity of the chemigum elastic material based on magnetorheology prepared by adding metal particles with a nickel core-shell structure and covered by titanium dioxide is controllable.

Description

technical field [0001] The invention belongs to the field of automobile parts preparation, and in particular relates to a highly oil-resistant nitrile rubber-based magnetorheological elastic material for automobiles 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...
