Abstract

The invention discloses an odorless fresh-keeping material, a preparation method thereof and a refrigerator. The odorless fresh-keeping material comprises a base material and a catalyst loaded on thebase material, the catalyst comprises a main catalyst, and the main catalyst comprises at least one of a water-soluble bivalent copper salt and a water-soluble monovalent copper salt. The deodorizingfresh-keeping material disclosed by the invention has high activity at normal temperature or even low temperature (-20 DEG C of a freezing chamber of a refrigerator), does not need to be heated and illuminated, and has good antibacterial and mildew-proof properties.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a taste-cleaning and fresh-keeping material, a preparation method thereof and a refrigerator. Background technique [0002] At present, with the improvement of living standards and the enhanced requirements for the application experience of refrigerators, the peculiar smell in the refrigerator is less and less accepted by people. These gases are not only foul-smelling, but most of them are harmful to health. [0003] In order to remove toxic and harmful gases in the refrigerator, various deodorizing technologies are applied in the refrigerator. Such as ozone deodorization generated by high-voltage discharge, photocatalyst deodorization, activated carbon adsorption deodorization, catalyst deodorization, etc. Among them, high-voltage discharge deodorization requires power consumption and has a good bactericidal effect, but the deodorization effect is average, and high-concentrat...
