Abstract

The invention discloses a nano-porous energy absorbing material as well as a preparation method and application thereof. The nano-porous energy absorbing material is prepared from nano-porous molecular sieves and functional fluid, wherein the nano porous molecular sieves are uniformly dispersed in the functional fluid, are treated molecular sieves and are one and a combination of more than one of ZSM-5, ZSM-22, beta, mordenite, Y, MCM-41 and SBA15; the functional fluid is one or a combination of more than one of water, ethylene glycol, glycerol and lubricating oil. By using the nano-porous material obtained by the preparation method disclosed by the invention, pore volume, aperture, specific surface and solid-liquid interface characteristics of the nano-porous material can be adjusted; in addition, the prepared nano-porous material has the advantages of small crystalline grains, stable performance and simple process; after the prepared nano-porous material is matched with the functional fluid, a corresponding energy absorbing system can be configured according to different application fields, and further maximum absorption of impact energy is reached.

Description

technical field [0001] The invention relates to a nano material and its preparation method and application, in particular to a nano porous energy absorbing material and its preparation method and application, and belongs to the technical field of nano new materials. Background technique [0002] With the development of the economy and the improvement of people's living standards, the requirements for high-quality sports shoes are becoming more and more stringent. Sports are not only performed in full swing in the arena, but also penetrate into the leisure life of the public. Modern sports shoes not only satisfy the function of durability and comfort, but also require lightweight, wear-resistant, energy-absorbing, non-deformable, high-resilience, and environmentally friendly materials, etc., to find sports characteristics from different sports, to achieve the best cushioning performance and the best stability. [0003] At present, most of the cushioning soles of sports shoes...
