Problems solved by technology

However, the rigidity of rubber is weak, and the load capacity and stability are poor. After long-term use, its shock-absorbing ability weakens more obviously. Moreover, the insulation performance of rubber is limited, and the safety factor when used as a shock-absorbing pad material is not enough.

Abstract

The invention discloses a method for preparing a nano-alumina-butadiene styrene rubber-porous polypropylene compound cushion material. The method comprises the following steps: uniformly dispersing nano-alumina in water to obtain a nano-alumina suspension; uniformly mixing with butadiene styrene, and performing spray drying by utilizing a centrifugal spray dryer to obtain nano-alumina-butadiene styrene rubber hybrid powder; mixing with polypropylene, maleic anhydride grafted polypropylene and other materials, performing melting extruding and granulating in a twin-screw extruder; adding a foaming agent, and performing micropore injection molding foaming with an injection molding machine to obtain the nano-alumina-butadiene styrene rubber-porous polypropylene compound cushion material. The cushion material has good insulating performance, strong load capacity, high stability, good damping and noise-reducing effect and excellent comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a method for preparing a nano-alumina-styrene-butadiene rubber-microporous polypropylene composite shock-absorbing pad material. Background technique [0002] With the rapid development of the national economy, my country's power generation and power consumption are increasing day by day. Transformers, as an important electrical equipment, have also developed rapidly and are widely used in residences, factories, mines, enterprises, power plants and other places. In the application of transformers, vibration is very important to the safe operation of transformers. It will not only increase the noise of transformer operation, which will endanger people's health, but also have an extremely adverse impact on the service life of transformers. Therefore, it is very important to improve the operation quality of transformers to reduce vibration by various means. [0003] At ...
