preparation example 1

[0042] Preparation Example 1: Add distilled water to cornstarch to prepare a cornstarch solution. The mass ratio of cornstarch to distilled water is 1:3. Stir and feed nitrogen. Stir in a water bath at 85°C for 30min, cool to 34°C, and Under the protection of nitrogen, add methyl acrylate with a concentration of 1120mol / L, stir for 5min, then add a solution of cerium ammonium nitrate with a concentration of 315×10-3mol / L, react at 34°C for 310-315h, and precipitate the product with absolute ethanol , washed three times with distilled water, dried by centrifugation and then dried to constant weight in a vacuum oven at 60°C.

preparation example 2-4

[0044] Rosin-modified phenolic resin in Preparation Example 2-4 is selected from the rosin-modified phenolic resin sold by Shanghai Nanke Electronic Trading Co., Ltd. with the brand name PR-12603, and the epoxy soybean oil is selected from the model sold by Guangzhou Zhongye Chemical Co., Ltd. It is the epoxy soybean oil of ESO, and black pigment is selected from the black pigment that the article number that Shenzhen Guanghong Plastic Pigment Co., Ltd. sells is 675, and nano-titanium dioxide is selected from the model that Anhui Xuancheng Jingrui New Material Co., Ltd. sells and is VK-T06S Nano-titanium dioxide, white peak wax is selected from Dongguang County Yilong Wax Products Factory, the brand is 62 # The white peak wax, chitosan is selected from the chitosan of item number 102 sold by Jiangsu Fushengde Biological Engineering Co., Ltd.

preparation example 2

[0045] Preparation Example 2: (1) According to the raw material ratio in Table 1, heat 20kg rosin-modified phenolic resin, 10kg epoxy soybean oil and 8kg modified methyl acrylate emulsion to 200°C, stir for 2 hours, and add 0.5kg antioxidant Agent 1010, 0.1kg silicone oil and 8kg filler, stir and cool down to 50°C, let stand for 3h, and solidify at 30°C for 5h, the modified methyl acrylate emulsion is made from Preparation Example 1, and the mass ratio of the filler is 1:0.5: Made of 0.3 nanometer titanium dioxide, chitosan and calcium carbonate;

[0046] (2) Mix the product obtained in step (1) with 10 kg of pigment, 2 kg of white peak wax and 0.6 kg of sodium lignosulfonate, stir and disperse for 40 minutes, mix well and grind to a particle size of 10 μm to obtain soybean ink, the pigment is black.

Abstract

The invention discloses a 100% biodegradable garbage bag with a traceable two-dimensional code identifier and a production method. The 100% biodegradable garbage bag with the traceable two-dimensionalcode identifier comprises a bag body and the two-dimensional code identifier printed on the bag body, wherein the bag body comprises the following components in percentage by weight: 6-10% of polylactic acid, 60-91% of poly (butyleneadipate-co-terephthalate) and 3-30% of modified starch; and the two-dimensional code identifier is produced through soybean oil ink spraying and curing. The 100% biodegradable garbage bag with the two-dimensional code identifier has the advantages that pollution to the environment can be reduced, the 100% biodegradable garbage bag with the two-dimensional code identifier is safe and environmentally friendly, both the two-dimensional code identifier and the garbage bag body are 100% degradable, and a two-dimensional code is high in adhesion, not liable to fadeand high in traceability.

Description

technical field [0001] The invention relates to the technical field of garbage bags, more specifically, it relates to a fully biological 100% fully degradable garbage bag with traceable two-dimensional code identification and a preparation method. Background technique [0002] At present, domestic domestic waste is in a state of chaotic collection. In some areas with better waste management, most of the waste will be treated in a harmless manner such as sanitary landfill, incineration, composting, etc., while the waste in more places is often simply piled or Landfilling causes bad odor and pollutes soil and groundwater. In order to improve the environmental awareness of the whole people, the state vigorously advocates citizens to consciously classify garbage. At present, domestic garbage in our country is generally divided into four categories: recyclable garbage, kitchen waste, hazardous garbage and other garbage. By sorting garbage into plastic bags for citizens, the burd...
