Porous foamy copper material and production method thereof

Abstract

The invention provides a porous foamy copper material and a production method thereof. The porous foamy copper material is prepared from the following components: polyurethane sponges, bronzing powder, sodium dodecylbenzene sulfonate, phosphatidylcholine, methyl 4-hydroxybenzoate, sodium diacetate, polyvinyl alcohol, polyvinyl formal, tristearin, sodium hydroxide, colophony, methyl cellulose, ethyl alcohol, an ammonia solution, and water. The porous foamy copper material is prepared through the following steps of (1) mixing and soaking the polyurethane sponges, the sodium hydroxide and the water; (2) mixing all the remaining components, stirring the mixed components with a stirrer so as to form pulp, and leaving the pulp to stand at room temperature; (3) putting the processed sponges into the pulp for repeated infiltration, and drying the sponges after the infiltration in the air to form a foamy body biscuit; and (4) putting foamy bodies under high vacuum so that copper oxide is decomposed, and performing sintering so as to obtain the porous foamy copper material. The porous foamy copper material disclosed by the invention is high in porosity factor, high in apparent density, and rough in surfaces; besides, the porous foamy copper material disclosed by the invention has a high plateau stress, so that the mechanical property is good.

Description

technical field

[0001] The invention relates to the field of foam materials, in particular to a porous copper foam material and a preparation method thereof. Background technique

[0002] With the rapid development of my country's economy and technology, the development of the material industry is also showing vigorous growth. Among them, porous metal is a new type of engineering material with a functional structure that has developed rapidly in recent years. It has low density, impact resistance, and low thermal conductivity. , good noise reduction effect and high hardness, so it is widely used in environmental protection construction, aerospace and electrochemistry and other industries. At present, the research on metal foam mainly focuses on metal foam with low density and high porosity, but metal foam with high porosity has the disadvantages of complex process, narrow range of material selection and high cost. Therefore, the research and development of a porous metal foa...
