Abstract

The invention discloses a preparation method for high-temperature-resistance deformation memory metal rubber and belongs to the technical field of metal rubber preparation. According to the preparation method, sludge of a sewage treatment plant, a glucose solution and the like are mixed and stand still, a supernatant is obtained through centrifuging, the supernatant, roots of elsholtzia splendens and the like are made into pulp and are mixed for fermentation, a supernatant is obtained through centrifuging and is inoculated to a culture medium prepared from peptone and the like for culturing and is drip-washed with sterile water, leacheate is obtained, mixing with nickel nitrate and the like is conducted, and filtrate is obtained through filtering; and filter residues are obtained through freezing and filtering, and the high-temperature-resistance deformation memory metal rubber is obtained through smelting, drawing, rolling, circulating pressing and heat treatment. The preparation method has the beneficial effects that the preparation steps are simple, the high temperature resistance of the obtained product is good, and the product is not burnt at the temperature of 710 DEG C to 730 DEG C; and corrosion resistance is good, no aging phenomenon exists, and the service life and the storage time are long.

Description

technical field [0001] The invention relates to a method for preparing high temperature-resistant deformation memory metal rubber, which belongs to the technical field of metal rubber preparation. Background technique [0002] Metal rubber is a kind of homogeneous elastic porous substance. It uses a certain process to arrange a certain quality, stretched, and spiral metal wires in a stamping (or rolling) mold in an orderly manner, and then use Formed by cold stamping method. Its raw material is metal wire, which has both the inherent properties of the chosen metal and its rubber-like elasticity. The material has rubber-like excellent elasticity and can withstand large deformation. Compared with ordinary rubber, it also has the advantages of durability, good corrosion resistance, and not easy to age. Since the metal rubber material is an elastic, capillary porous structure, its interior is formed by the interfitting and interlocking of metal wires. When subjected to vibrati...
