Problems solved by technology

However, in this method, the polyurethane sponge is soaked in a strong acid solution in the roughening step, and the polyurethane sponge is prone to carbonization for a long time, and subsequent production cannot be carried out; in addition, the process flow is complicated, chemical solvents are used more, raw material costs are high, and waste water is discharged. Large amount, polluting the environment, but also increased the burden of sewage treatment of enterprises

Abstract

The invention discloses a preparation method of a foam tin material. The preparation method comprises the following steps that vacuum magnetron sputtering nickel plating is conducted on a polymeric sponge; the conductive polymeric sponge subjected to the above treatment is subjected to nickel plating in a plating fluid, and washing and drying are performed to obtain the foam tin material. Nickel is plated on the polymeric sponge by adopting a vacuum magnetron sputtering technology, then electrolytic tinning is performed, the whole process is simple, the polymeric sponge does not need coarsening and other pretreatment, the preparation method saves energy and is friendly to the environment, large-scale continuous production can be performed, the finally obtained foam tin material passes EDSdetection, no nickel is detected, it is proved that the nickel content is very low, and the tin content reaches 99.7%. Compared with the prior art, the tin purity is greatly improved, and correspondingly the performance of foam tin is also improved.

Description

technical field [0001] The invention belongs to the field of foam metal materials, and in particular relates to a preparation method of foam tin materials. Background technique [0002] Due to the characteristics of light weight, large specific surface area, high specific strength, uniform structure, and excellent energy absorption, metal foam has dual properties of function and structure, and is widely used in chemical industry, energy, catalyst carrier, sound absorption, shock absorption, etc. Among them, tin foam is a new type of metal foam with random openings and high porosity with controllable pore size, which can be widely used in catalyst carriers and shock-absorbing and sound-absorbing materials. [0003] The preparation method of traditional tin foam materials is usually to perform electroless copper plating or electroless nickel plating on the polyurethane sponge after roughening, sensitization, activation, and degumming, and then electroplating on the surface of ...
