Microfluidic bionic bearing double-lip rubber sealing element and preparation method thereof

The invention discloses a micro-fluidic bionic bearing double-lip rubber sealing element and a preparation method thereof. The micro-fluidic bionic bearing double-lip rubber sealing element comprises a metal framework, foaming fluororubber, matrix fluororubber and a storage structure, the foamed fluororubber is adhered to the upper side of the metal framework, and a micro-channel structure is arranged in the foamed fluororubber; the matrix fluororubber is adhered to the lower side of the metal framework; the metal framework is formed by mutually bonding and wrapping foamed fluororubber and matrix fluororubber to jointly form a storage structure, the surfaces of the matrix fluororubber and the foamed fluororubber are provided with fish scale-shaped bionic structures, and micropores are formed in the concave positions of the fish scale-shaped bionic structures. In the working process, storage and release of lubricating oil or lubricating grease can be achieved according to temperature changes, the lubricating o
