Abstract

The invention discloses a nano-fluid energy-absorbing material and a preparation method and application thereof. The preparation method includes the steps that an additive and a base solution are mixed according to the mass ratio, and a mixed solution A is obtained; under the condition of low-speed stirring, a thickening agent with the mass ratio of the thickening agent to the additive being 1: 0.1 is added into the mixed solution A, high-speed stirring is conducted, and a mixed solution B is obtained; under the condition of high-speed stirring, the mixed solution B is heated; and a nano porous material in a mass ratio of 1: 0.5 is added into the mixed solution B, uniformly stirred and mixed at a high speed, and cooled to room temperature to obtain the nano-fluid energy-absorbing material. The prepared energy-absorbing material improves the energy-absorbing density and the protection performance under the collision impact condition, and can meet the mining requirements of coal mine flame retardance, static electricity resistance and the like. The material is suitable for safety protection in coal mine trackless transportation equipment.

Description

technical field [0001] The invention relates to an energy-absorbing material, in particular to a nanofluid energy-absorbing material, a preparation method and an application thereof. Background technique [0002] In recent years, with the rapid development of trackless transportation equipment and technology in modern large-scale coal mines, the production efficiency and economic benefits of coal mines have been greatly improved. economic losses and casualties. However, there are no industry and product standards related to the safety protection of trackless transportation in coal mines. Most of them use anti-collision barrels or waste tires for safety protection. Among them, the materials used for anti-collision barrels are mainly plastic materials, and the tires are mainly made of rubber. Materials, such materials have poor energy consumption effect and cannot play an effective safety protection role. [0003] In order to effectively mitigate the damage caused by collisi...
