preparation example Construction

[0013] The invention provides a method for preparing a sterilizing additive for a fresh-keeping box cover, comprising:

[0014] 1) Activate the silica gel under steam conditions;

[0015] 2) mixing silica gel, nano-zinc, nano-cobalt, nano-titanium dioxide, micron-sized palladium oxide, starch, methylcellulose and water to prepare a mixture;

[0016] 3) The mixture is dried and ball-milled to prepare a sterilizing additive for the lid of a fresh-keeping box.

[0017] In step 1) of the above-mentioned preparation method, the conditions of the activation treatment can be selected in a wide range, but in order to make the sterilizing additive to have a more excellent sterilizing effect, preferably, in step 1), the activation treatment The following conditions are met: the treatment temperature is 100-120°C, and the treatment time is 6-8h.

[0018] In step 1) of the above-mentioned preparation method, the average particle diameter of silica gel can be selected in a wide range, bu...

Embodiment 1

[0026] 1) Activate the silica gel (with an average particle size of 90 mesh) under steam conditions (the treatment temperature is 110°C, and the treatment time is 7h);

[0027] 2) Silica gel, nano-zinc (average particle size is 13nm), nano-cobalt (average particle size is 22nm), nano-titanium dioxide (average particle size is 20nm), micron palladium oxide (average particle size is 9μm), starch, formazan Base cellulose and water are mixed according to the weight ratio of 50:1.2:0.3:0.9:1.3:35:2.3:70 (mixing temperature is 25°C, mixing time is 3h) to prepare a mixture;

[0028] 3) The mixture was dried (the drying temperature was 118° C., and the drying time was 4 h), and ball milled to prepare the sterilization additive A1 for the lid of the crisper.

Embodiment 2

[0030] 1) Activate the silica gel (with an average particle size of 80 mesh) under steam conditions (the treatment temperature is 100°C, and the treatment time is 6 hours);

[0031] 2) Silica gel, nano-zinc (average particle size is 10nm), nano-cobalt (average particle size is 20nm), nano-titanium dioxide (average particle size is 12nm), micron palladium oxide (average particle size is 3μm), starch, formazan Base cellulose and water are mixed according to the weight ratio of 50:1:0.1:0.6:1:30:2:50 (mixing temperature is 15°C, mixing time is 2h) to prepare a mixture;

[0032] 3) The mixture was dried (the drying temperature was 115° C., and the drying time was 3 h), and ball milled to prepare the sterilization additive A2 for the lid of the crisper.

Abstract

The invention discloses a sterilization additive for a fresh-keeping box cover and a preparation method of the sterilization additive. The preparation method comprises the following steps: 1) carryingout activating treatment on silica gel under a steaming condition; 2) mixing the silica gel, nano zinc, nano cobalt, nano titanium dioxide, micrometer-grade palladium oxide, starch, methyl celluloseand water to obtain a mixture; and 3) drying the mixture and carrying out ball milling to obtain the sterilization additive for a fresh-keeping box cover. The sterilization additive has an excellent sterilization effect and then can be applied to a fresh-keeping box cover, and meanwhile, the preparation method has the advantages of simple process and easily obtained raw materials.

Description

technical field [0001] The invention relates to a fresh-keeping box cover, in particular to a sterilization additive for a fresh-keeping box cover and a preparation method thereof. Background technique [0002] Fresh-keeping boxes are one of the essential items in daily life, and the fresh-keeping box cover is one of its necessary parts. At present, the lid of the fresh-keeping box is mainly made of polymer, which has excellent mechanical properties. [0003] Although the existing fresh-keeping box cover can meet most of the living requirements, bacteria are easy to breed on the fresh-keeping box cover after long-term use, and the sterilization performance of the fresh-keeping box cover still needs to be improved, otherwise it is very easy to cause physical harm to the user . Contents of the invention [0004] The purpose of the present invention is to provide a sterilizing additive for fresh-keeping box cover and its preparation method. The sterilizing additive has an e...
