Embodiment 1

[0009] ① Take 17.5 kg of polycaprolactone, 25 kg of calcium carbonate, 5 kg of talcum powder, 1.5 kg of vegetable oil, and 1 kg of stearic acid in the following weights;

[0010] ②Put the above-mentioned substances in the ratio of parts by weight into a stirring mixer, and when the stirring temperature reaches 110°C, it will become a premixed powder, and put the premixed powder into a co-rotating twin-screw extruding granulator to heat up and make Then put the special masterbatch into a single-screw extruder to extrude and plasticize, then use infrared and ultraviolet rays to sterilize and sterilize, inspect and pack, and then get disposable biodegradable tableware.

Embodiment 2

[0012] ① Take 35 kg of polycaprolactone, 50 kg of calcium carbonate, 10 kg of talcum powder, 3 kg of vegetable oil, and 2 kg of stearic acid in the following weights;

[0013] ②Put the above-mentioned substances in the ratio of parts by weight into a stirring mixer, and when the stirring temperature reaches 130°C, it will become a premixed powder, and put the premixed powder into a co-rotating twin-screw extruding granulator to heat up and make Then put the special masterbatch into a single-screw extruder to extrude and plasticize, then use infrared and ultraviolet rays to sterilize and sterilize, inspect and pack, and then get disposable biodegradable tableware.

Embodiment 3

[0015] ① Take 17.5-70 parts of polycaprolactone, 25-100 parts of calcium carbonate, 5-20 parts of talcum powder, 1.5-6 parts of vegetable oil, and 1-4 parts of stearic acid in the following weights;

[0016] ②Put the above-mentioned substances in the ratio of parts by weight into a stirring mixer, and when the stirring temperature reaches 140°C, it will become a premixed powder, and put the premixed powder into a co-rotating twin-screw extrusion granulator to heat up and make Then put the special masterbatch into a single-screw extruder to extrude and plasticize, then use infrared and ultraviolet rays to sterilize and sterilize, inspect and pack, and then get disposable biodegradable tableware.

Abstract

A disposable biodegradable container for food or beverage is prepared from polycaprolactone, calcium carbonate, talc powder, plant oil and stearic acid through stirring, pugging, extrusion granulating, extrusion shaping, sterilizing and disinfecting.

Description

technical field [0001] The invention relates to a production process of disposable biodegradable tableware. Background technique [0002] Entering the new century, with the rapid economic development and the widespread application of disposable packaging products in daily life, white pollution has become a social hazard that restricts human survival and development. In particular, mass production and use of non-degradable foamed plastic tableware not only causes a huge waste of resources, but also seriously pollutes the environment. Most of the light and biological non-foaming disposable tableware produced in the prior art are made of polypropylene, polyethylene with added starch or calcium carbonate or talcum powder, olefin lubricant, etc. This process belongs to the disintegrating type, not a complete Biodegradable. Contents of the invention [0003] The purpose of the present invention is to provide a pollution-free and completely degradable disposable biodegradable t...
