Abstract

The invention discloses a hindered phenol / montmorillonoid / nitrile rubber composite damping material for a car. The hindered phenol / montmorillonoid / nitrile rubber composite damping material comprises raw materials including, by weight, 40-60 parts of nitrile rubber, 30-40 parts of chlorinated butyl rubber, 128-160 parts of tetrahydrofuran, 42-61 parts of maleic anhydride, 2-6 parts of benzoyl peroxide, an appropriate amount of ethyl alcohol, 1-3 parts of hydroxide sodium hypophosphite, an appropriate amount of xylene, 24-33 parts of softwood celluloses, 1-2 parts of stearic acid, 2-7 parts of carbon black, 1-2 parts of sulphur, 4-7 parts of montmorillonoid, 2-4 parts of hindered phenol HP1098, an appropriate number of calcium chloride solution and an appropriate amount of deionized water. According to the hindered phenol / montmorillonoid / nitrile rubber composite damping material, the maleic anhydride and the nitrile rubber are grafted, and are then grafted with the softwood celluloses for compounding; on one hand, internal friction resistance of rubber molecular chain activity is strengthened, and the damping performance of the material is strengthened; and on the other hand, the character of the softwood celluloses is used for improving the sound absorption and noise lowering performance of the damping material, and the nitrile rubber damping material which is excellent in sound absorption and noise lowering performance is prepared.

Description

technical field [0001] The invention belongs to the field of automobile parts preparation, in particular to a hindered phenol / montmorillonite / nitrile rubber composite damping 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 applications in 8-12 parts such as hoardings, car doors, car roofs, car floors, and trunks. Therefore, the research and development of new high-efficiency damping materials with excellent comprehensive performance has become a hot spot at home and abroad. [0003] In the article "Preparation and Performance Research of Blended Wide Temperature Range High Damping Rubber Material" published by Tian Min, L...
