Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with specific embodiments. A method for manufacturing stainless steel foam metal. First, a square foam metal sponge molded container is prepared. The material of the molded container is various common thermoplastic or thermosetting plastics, such as polypropylene, and the inner surface of the foam metal sponge molded container is smooth; Spread the mold release agent, such as butter, on the inner wall of the above foamed metal sponge body molding container uniformly, and then place it in the foaming workshop. At a temperature of about 15°C, 65 kg of polyoxypropylene polyol with glycerin as the initiator ( Hydroxyl value 56) and modified polyester polyol (hydroxyl value 80, acid value less than 1), 15kg of polyoxypropylene polyphenylethyl polyacrylonitrile and polyol (hydroxyl value 28) with glycerin as starter To the main ingredients, add 4kg water, 2kg cyclopentane, 0.15kg A33 (33% triethylen...

Abstract

The invention discloses a method for preparing stainless steel foam metal and belongs to the technical field of production of foam metal. The method for preparing the stainless steel foam metal comprises the steps that after polyether or polyester polyol, a catalyst, a surface active agent and a foaming agent are stirred, stainless steel powder is added to the mixture and then is evenly stirred; then a curing agent is added, and the mixture is placed in a forming container for reacting and curing after sufficient and even mixing; tapping processing is conducted on a cured foam metal sponge body; and the stainless steel foam metal can be obtained through high-temperature reductive sintering. According to the method for preparing the stainless steel foam metal, the three-dimensional netty foam metal is directly formed through a polymerization reaction and a foaming process, and production procedures are greatly simplified; the obtained stainless steel foam metal is uniform in structure, and manpower demands and the labor amount of workers can be greatly reduced; the stability of the performance of products can be improved while the production cycle is shortened.

Description

Technical field [0001] The invention belongs to the technical field of foam metal production, and in particular relates to a method for preparing stainless steel foam metal. Background technique [0002] Foam metal is a metal material containing foam-like pores. Compared with general sintered porous metal, foam metal has higher porosity and larger pore size. Since foamed metal is a two-phase composite material composed of a continuous phase of a metal matrix framework and a dispersed or continuous phase of pores, its properties depend on the metal matrix used, porosity and pore structure, and are affected by the preparation process. Generally, the mechanical properties of foam metal decrease with the increase of porosity, and its electrical conductivity and thermal conductivity also decrease exponentially. When the foam metal is under pressure, the force-receiving area increases due to the collapse of the pores and the material strain hardening effect makes the foam metal have e...
