preparation example Construction

[0037] The preparation method of this modified antimicrobial agent, see attached figure 1 , including the following steps:

[0038] S1: Mix the isomaltooligosaccharide and the yeast powder in a set ratio and then stir to form the first mixture after being uniform;

[0039] S2: fermenting the first mixed material to obtain lysozyme;

[0040] S3: mixing taurine, citric acid, nano-titanium dioxide, zinc oxide, and ultraviolet fluorescent powder, adding water and grinding to obtain a second mixture;

[0041] S4: Spray drying the second mixture to obtain a composite powder;

[0042] S5: Stir after mixing the chlorophyll, tea polyphenols and the composite powder, and obtain the third mixture after uniformity;

[0043] S6: After mixing the lysozyme, chitosan and the third mixture, stirring, and uniformly forming a finished product of the modified antibacterial agent.

[0044] Further, step S2 specifically includes: fermenting the first mixed material in a stainless steel fermente...

Embodiment 1

[0048] S1: Mix 12 parts of isomalto-oligosaccharide and 0.9 part of yeast powder and then stir to form the first mixture;

[0049] S2: ferment the first mixed material in a stainless steel fermentation tank to obtain lysozyme; the fermentation time is controlled at 168 hours;

[0050] S3: After mixing 10 parts of taurine, 0.9 parts of citric acid, 38 parts of nano-titanium dioxide, 4 parts of zinc oxide, and 4.5 parts of ultraviolet fluorescent powder, add pure water to grind in a sander to obtain the second mixture; the grinding time is 3 hours;

[0051] S4: Spray drying the second mixture to obtain a composite powder;

[0052] S5: Mix 9 parts of chlorophyll, 9 parts of tea polyphenols with the composite powder and stir to obtain a third mixture;

[0053] S6: Mix lysozyme, 6 parts of chitosan and the third mixture, then stir, and evenly form a finished product of the modified antibacterial agent.

Embodiment 2

[0055] S1: Mix 10 parts of isomaltooligosaccharide and 1 part of yeast powder and then stir to form the first mixture;

[0056] S2: ferment the first mixed material in a stainless steel fermentation tank to obtain lysozyme; the fermentation time is controlled at 168 hours;

[0057] S3: After mixing 10 parts of taurine, 1 part of citric acid, 40 parts of nano-titanium dioxide, 5 parts of zinc oxide, and 5 parts of ultraviolet fluorescent powder, add pure water to grind in a sander to obtain the second mixture; the grinding time is 3 hours;

[0058] S4: Spray drying the second mixture to obtain a composite powder;

[0059] S5: Mix 10 parts of chlorophyll, 10 parts of tea polyphenols with the composite powder and then stir to obtain the third mixture;

[0060] S6: Mix lysozyme, 8 parts of chitosan and the third mixture and then stir to form a finished product of the modified antibacterial agent after uniformity.

Abstract

The invention relates to broad-spectrum antiviral bactericidal plastic and application thereof. The bactericidal plastic is prepared from following components in percentage by weight: 90-96% of basicresin, 1-3% of a modified antibacterial agent, and 0-10% of a plastic additive, wherein the modified antibacterial agent is prepared from the following components in parts by weight: 5 to 15 parts ofchlorophyll, 5 to 15 parts of tea polyphenol, 8 to 16 parts of taurine, 0.5 to 2 parts of citric acid, 6 to 18 parts of isomalto-oligosaccharide, 0.6 to 1.5 parts of yeast powder, 4 to 10 parts of chitosan, 30 to 50 parts of nano titanium dioxide, 3 to 8 parts of zinc oxide and 3 to 8 parts of ultraviolet fluorescent powder. The broad-spectrum antiviral bactericidal plastic has a broad-spectrum antiviral effect, can kill viruses and bacteria for a long time, effectively prevents virus infection possibly caused by frequent contact between users and plastic cards such as bank cards and identitycards, and is beneficial to the health of the users.

Description

technical field [0001] The invention relates to the technical field of plastic materials, in particular to a broad-spectrum antiviral and bactericidal plastic and its application. Background technique [0002] Plastic products are widely used in daily life because of their light weight, good chemical stability, and good corrosion resistance. For example, the substrates of various bank cards, ID cards, membership cards and other cards are all made of plastic, and these cards are usually carried by people and used in frequent contact. When the cards are contacted and carry viruses or bacteria, it may cause the user to get sick. infection and spread. [0003] At present, there are few antibacterial plastic products on the market, especially the plastics used to produce plastic card substrates such as bank cards and ID cards have almost no antiviral and bactericidal functions. Therefore, if a broad-spectrum antiviral and bactericidal plastic can be developed to make it The pre...
