preparation example Construction

[0013] The invention provides a method for preparing a bactericidal plastic bag. The preparation method comprises: mixing polypropylene, acrylonitrile, phenolic resin, coupling agent and antioxidant, extruding and granulating to obtain a masterbatch M; Chitin, castor oil, horseradish and Prunella vulgaris are heated and mixed and then filtered to obtain the antibacterial agent N; blending the masterbatch M and the antibacterial agent N, and going through a film blowing process to obtain the bactericidal plastic bag; wherein, relative to 100 weight parts of polypropylene, the amount of the acrylonitrile is 20-40 parts by weight, the amount of the phenolic resin is 10-25 parts by weight, the amount of the coupling agent is 1-8 parts by weight, the antioxidant The consumption is 2-10 parts by weight, the consumption of said chitin is 2-10 parts by weight, the consumption of said castor oil is 5-10 parts by weight, the consumption of said horseradish is 1-8 parts by weight, the con...

Embodiment 1

[0022] After mixing 100g polypropylene (weight-average molecular weight is 6000), 25g acrylonitrile, 15g phenolic resin, 4g vinylsilane and 4g methylphenol, extrude and granulate to obtain masterbatch M; mix 4g chitin, 6g castor oil , 3g wasabi and 7g Prunella vulgaris were heated and mixed and then filtered (the temperature of heating and mixing was 60°C and the time was 20min) to obtain antibacterial agent N; masterbatch M and antibacterial agent N were blended, and the film blowing process was used to obtain antibacterial plastic Bag A1.

Embodiment 2

[0024] After mixing 100g polypropylene (weight-average molecular weight is 9000), 35g acrylonitrile, 20g phenolic resin, 6g aminosilane and 8g dimethylphenol, extrude and granulate to obtain masterbatch M; mix 8g chitin, 7g castor oil , 6g of horseradish and 9g of Prunella vulgaris were heated and mixed and then filtered (the temperature of heating and mixing was 75°C and the time was 25min) to obtain antibacterial agent N; the masterbatch M and antibacterial agent N were blended, and after the film blowing process, the antibacterial plastic was obtained Bag A2.

Abstract

The invention discloses a self-sterilization plastic bag and a preparation method thereof. The preparation method includes the following steps: after mixing polypropylene, acrylonitrile, phenolic resin, coupling reagent and antioxidant, conducting extrution prilling to obtain master batch M; heating, mixing and filtering chitin, castor oil, wasabi and selfheal to obtain antibacterial agent N; and mixing the master batch M and the antibacterial agent N and then carrying out the film blowing process to obtain the self-sterilization plastic bag. By the self-sterilization plastic bag, the problem that traditional plastic bags are poor in antibacterial ability and easy in bacteria breeding is solved, and especially the problem that fruits and vegetables contained in the traditional plastic bags for a long time are easy and fast to rot is solved.

Description

technical field [0001] The invention relates to the preparation of a plastic bag, in particular to a bactericidal plastic bag and a preparation method thereof. Background technique [0002] Plastic bags are indispensable items in people's daily life. They are often used to hold other items. They are widely used because of their cheapness, light weight, large capacity, and easy storage. Plastic bags are also often used to hold fruits and vegetables. Traditional plastic bags have poor antibacterial ability and are easy to breed bacteria. If they are used to hold fruits, vegetables and other items for a long time, they will easily accelerate their decay. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a bactericidal plastic bag with strong antibacterial ability and not easy to breed bacteria and its preparation method. Contents of the invention [0004] The purpose of the present invention is to provide a kind of antibacterial pla...
