Problems solved by technology

[0006] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a mask outer packaging bag that can be expired at a fixed time and its production method: first prepare a biodegradable film with good biodegradability, and then coat the biodegradable film on the biodegradable film Antibacterial and hydrophobic coatings with good antibacterial and antibacterial properties, water repellency and stain resistance, obtain a timed failure film, cut the timed failure film and make a packaging bag, and obtain the mask outer packaging bag that can be timed failure, which solves the problem of existing mask packaging After the bag is in contact with water, oil and dust, it is easy to pollute other masks when taking the mask. At the same time, it will corrode the mask packaging bag and affect the hygiene of the mask. Difficult to degrade, bringing more pollution problems to the environment

Embodiment 1

[0059] This example is a method of preparing an antibacterial hydrophobic resin comprising the steps of:

[0060] Step 1: 0.03 mol of dichlorosulfoxide, 0.01 g of the polymerization agent is added to the three flask mounted to a thermometer, a condensate return tube, a constant voltage drip funnel, and a stirrer, stirring at a temperature of 10 ° C, stirring The rate of 0.1 mol acrylic acid was added dropwise over the conditions of 200R / min, and the drip rate was 1 drop / s, and the reaction was refluxed after the dropping temperature of 40 ° C, and the reaction product was cooled after the reaction was completed. At room temperature, the fraction of 30 ° C was collected under pressure of 18.7 kPa, and an intermediate 1 was collected under conditions of 18.7 kPa.

[0061] Step 2: 0.01 g of the polymerization agent to benzene and 0.1 mol1H, 1H-pentafluoropropanol were added to the three flasks mounted with a thermometer, a constant pressure drip funnel, and a stirrer, at a temper...

Embodiment 2

[0068] This example is a method of preparing an antibacterial hydrophobic resin comprising the steps of:

[0069] Step 1: 0.06 mol of dichlorosulfoxide, 0.03 g of the polymer polymer added to the three flask mounted with a thermometer, condensate return tube, constant voltage drip funnel, and stirrer, stirring at a temperature of 20 ° C, stirring The mixture was added dropwise on the side of the rate of 300r / min, and the drip rate was 1 drop / s, and the reaction was refluxed under the temperature of 50 ° C, and the reaction product was cooled after the reaction was completed. After room temperature, the fraction of 32 ° C was collected under pressure of 18.7 kPa, resulting in an intermediate 1;

[0070] Step 2: Add 0.03 g of the polymer polymer to the three flask mounted with a thermometer, a constant voltage drip funnel, and a stirrer, and a stirring rate at a temperature of 85 ° C, stirring at a temperature of 85 ° C, stirring rate A 0.1 mol intermediate 1 was added dropwise ...

Embodiment 3

[0077] This embodiment is a method of producing a mask outer packaging bag for a certain time, including the following steps:

[0078] S31: In accordance with the weight, 50 parts of the antibacterial hydrophobic resin from Example 1, 20 copies of butyl acetate, 10 titanium powder, 5 silicon powder, and spare;

[0079] S32: The antibacterial hydrophobic resin, butyl acetate is added to the mixer, and mixed for 30 min under conditions having a stirring rate of 500 r / min to give a mixture;

[0080] S33: Add titanium white powder to the mixture, silicon fine powder continues to stir mixture for 1 h to obtain antibacterial hydrophobic coating;

[0081] S34: 0.1 parts of PBAT20, 60 parts of polylactic acid and 1,4-bis-tert-butyl peroxy isopropylbenzene, and spare;

[0082] S35: Place PBAT, polylactic acid in a vacuum drying tank, dried under temperature of 80 ° C, then dried PBAT, polylactic acid, and crosslinking agent 1,4-bis-t-butyl peroxide Benzene is added to the screw extruder ...

Abstract

The invention discloses a mask outer packaging bag capable of invalidating regularly and a production method thereof, and relates to the field of packaging bags, a biodegradable film with good biodegradability is prepared firstly, then the biodegradable film is coated with an antibacterial and hydrophobic coating with good antibacterial and bacteriostatic performance and water-repellent and stain-resistant performance, and a timed invalidating film is obtained; the mask outer packaging bag capable of invalidating regularly is obtained by cutting the timed invalidating film into a packaging bag, the mask outer packaging bag capable of invalidating regularly has good antibacterial and hydrophobic performance, the antibacterial performance can ensure that the safety is good and bacterial pollution is avoided when the mask is loaded, and the hydrophobic performance can ensure that the packaging bag is not easy to stick dust and rot when meeting water, and the sanitation degree of the mask is further ensured; after the mask outer packaging bag capable of invalidating regularly is discarded, the biodegradable film is exposed after the mask outer packaging bag is crushed, and the mask outer packaging bag can be quickly degraded through good biodegradability.

Description

Technical field [0001] The present invention relates to the field of packaging bags, and in particular to a mask outer packaging bag and its production method thereof. Background technique [0002] The mask is a hygiene product, generally noted that the mouth is used to filter into the mouth of the mouth, to achieve the harmful gas, the odor, the applique to the wearer's nose, and are made of gauze or paper. [0003] The mask has a certain filtering effect on the air entering the lungs. When the respiratory infectious disease is popular, wearing a mask has a very good role when working in a contaminated environment such as dust. Environmental pollution is deep, especially air pollution, so everyone's demand for masks is getting bigger. [0004] After the existing mask packaging bags are exposed to water, oil and dust, it is easy to cause contamination to other masks while getting the mask, while the mask packaging bag is corrupted, affecting masks, if using a packaging mask, addi...
