Embodiment 1

[0045] 1. Prepare foam metal by electrodeposition method:

[0046] First, the continuous polymer sponge is used as the matrix, and the conductive adhesive is applied to the conductive treatment. After removing the film, pressing uniformly, drying and curing, the sulfamate system is used to treat it at a temperature of 40-50 °C. Conduct electroplating, then oxidize at 600°C for 12 minutes, remove the substrate sponge, and reduce and sinter at 900°C for 40 minutes in a hydrogen atmosphere to obtain porous iron foam with a pore size of 45 PPI and a porosity of about 97.5%.

[0047] 2. Treatment of porous metal foam

[0048]Soak the obtained porous foam iron in lye degreasing solution at 50~55℃ for 18~20 minutes, rinse with hot water once, wash with warm water for 2~3 times, and then use 10g / l hydrochloric acid at 20~25℃. Soak at ℃ for 12 to 15 minutes, wash with water 2 to 3 times, and then immerse in colloidal palladium activation solution for 5 to 10 minutes.

Abstract

The invention relates to a lampblack filtering material comprising porous foam metal and a preparation method of the lampblack filtering material. The lampblack filtering material comprises the porous foam metal of an open-type porous network structure, wherein the porosity of the porous foam metal ranges from 90% to 99%, and the pore size ranges from 20PPI to 200PPI. The pore surface of the porous foam metal comprises one or two of antibacterial plating solution and mildew preventive. The porous-foam-metal lampblack filtering material used for lampblack air filtration, especially the porous-foam-metal lampblack filtering material with bacteria inhibition and mildew prevention performance, is particularly applicable to filtration of indoor lampblack air.

Description

technical field [0001] The invention relates to a porous metal foam metal oil fume filter material for oil fume air filtration, in particular to a porous metal foam metal oil fume filter material with antibacterial and anti-mildew properties for oil fume air filtration and a preparation method thereof, and is especially suitable for indoor oil fume Air filtration. technical background [0002] With the continuous improvement of people's quality of life, the requirements for the purification of cooking fumes from catering kitchens are getting higher and higher, and the state's efforts to control the pollution of catering cooking fumes are also increasing. GB18483-2001), which stipulates the maximum allowable emission concentration of cooking fume and the minimum removal rate of cooking fume purification equipment. At present, among all kinds of equipment used for kitchen oil fume purification and filtration, the filter adsorption type oil fume purifier has high purification ...
