Abstract

The invention relates to a hydrogenated carboxylated nitrile butadiene rubber based damping composite material and a preparation method thereof. The hydrogenated carboxyl nitrile rubber based damping composite material comprises 60-90 parts of HXNBR and 10-40 parts of hindered phenol antioxidant. The preparation method comprises the following steps of: opening the HXNBR on a two-roll open mill, and then adding the hindered phenol antioxidant, and mixing evenly, thereby obtaining a mixed rubber piece; paving the mixed rubber piece cooled previously in the inner cavity of a mold, clamping the mold by using steel plates up and down and adding a layer of high-temperature anti-sticking film between the mold and each steel plate; next, moving the mounted steel plates to a press vulcanizer, preheating for 5-10 min at 110-130 DEG C under pressure relief condition, adjusting the pressurization pressure of the press vulcanizer to the range of 8-10 MPa, pressurizing for 10-30 min at 110-130 DEG C, relieving pressure, taking out the steel plates, and then cooking and demolding, thereby obtaining the hydrogenated carboxylated nitrile butadiene rubber based damping composite material. The preparation method of the hydrogenated carboxylated nitrile butadiene rubber based damping composite material is simple to operate, low in production cost and low in environmental pollution, and meets the sustainable development requirement and has a high economic and environmental protection value.

Description

Technical field [0001] The invention belongs to the field of damping composite materials and their preparation, and particularly relates to a hydrogenated carboxyl nitrile rubber damping composite material and a preparation method thereof. Background technique [0002] With the advancement of industrialization, the acceleration of urbanization and the improvement of living standards, various sources of vibration and noise are increasing. In most cases, the resulting vibration and noise will adversely affect industrial production and people’s lives. To harm, measures should be taken to reduce vibration and noise. Polymer damping materials are widely used in practice because of their good damping performance, high strength, good toughness, and easy processing. However, the use of a single polymer has the problem that the use temperature range and damping performance often cannot meet the actual needs. For this reason, it needs to be modified to meet the needs of practical applicat...
