Example Embodiment

[0046] Example one:

[0047] 30 kg of starch acetate, 6 kg of glycerin, 1 kg of urea, 4 kg of sorbitol, 1 kg of talc, 4 kg of ethylene-acrylic acid copolymer, 4 kg of diglycidyl azelate, and polybutylene succinate 50 kg.

Example Embodiment

[0048] Embodiment two:

[0049] 40 kg of hydroxypropyl starch, 1 kg of glycerin, 0.5 kg of urea, 6 kg of sorbitol, 2 kg of talc, 4.5 kg of ethylene-acrylic acid copolymer, 6 kg of diglycidyl azelate, polybutylene succinate 40 kg of ester.

[0050] The pelletizer of the present invention adopts a twin-screw extruder. The molten strips extruded in the pelletizer are cooled by water cooling. After the above-mentioned raw materials are uniformly stirred, the pelletizing process needs to be intermeshing with each other. In the same direction twin screw extruder. The specific process is: preheat the barrel of the ZSK-58 intermeshing co-rotating twin-screw extruder, and set the temperature as:

[0051] Zone 1 Zone 2 Zone 3 Zone 4 Zone 5 Zone 6

[0052] 125℃ 165℃ 168℃ 168℃ 160℃ 155℃

[0053] When the preheating temperature of each zone of the machine reaches the set temperature, start the main motor speed regulator, adjust the screw speed to 250-300rpm / min; start the mixing feeder, set the f...

Abstract

The invention relates to the technical field of producing methods of degradable materials, in particular to a preparation method of a biological resin material for a blown film. The preparation method comprises the following steps of: adding modified starch, poly(butylene succinate), talcum powder, urea and ethylene-acrylicacid copolymer into a high-speed mixer, stirring for 2 minutes, slowly adding glycerol, sorbitol and glyceride and pressing a button of low-speed rotation and high-speed operation to enable the materials to be sufficiently stirred evenly in the mixer; placing the evenly mixed material into a pelletizer for mixing, and then melting, extruding, cooling and dicing to obtain a biodegradable resin granular material for manufacturing a water retention membrane. The production process has simple process, less working procedures and high efficiency. A film manufactured by adopting the biological resin material can be completely decomposed into carbon dioxide and water within three mouths to one year after being abandoned in the nature and has high decomposing speed, thereby the biological resin material is an ideal material for replacing the traditional non-degradable water retention membrane and managing the white pollution of farmlands.

Description

Technical field: [0001] The invention relates to the technical field of production methods of degradable materials, and relates to a preparation method of bioresin materials used for film blowing. Background technique: [0002] As we all know, white pollution is constantly destroying the environment on which we live. The whole world is trying to find ways to eliminate the harm caused by "white pollution". The shortage of oil resources and rising oil prices have brought many unstable factors to human daily work and life, and seriously affected the environment of the entire society. [0003] For a long time, the agricultural film materials (such as water-retaining film) we have used are disposable products made of petroleum synthetic resins, such as polyvinyl chloride, polypropylene, polyethylene, etc., and are discarded as garbage after use. , some are discarded everywhere, and some are buried or burned, which greatly wastes resources. These plastic products take about 200 ...
