Problems solved by technology

From adding starch to paper-plastic replacement, from lactic acid polymerization to thermoplastic corn starch materials, it can be said that great progress has been made in technology, but the cost performance of the product cannot be compared with ordinary plastics, and it can only be used in high value-added fields.
Through the existing technology, due to the filling amount of starch and the dissolution of starch, the material cannot be completely degraded

Abstract

The invention discloses a device and a method for producing a fiber-filled starch-based fully-biodegradable material. On the basis of existing production equipment, a twin-screw extruder, a smelting furnace and a high-speed mixer are connected in series and recombined to obtain a complete production line, so that the operation is relatively simple, a production process is relatively stable, and the production efficiency is remarkably improved; the production line is suitable for the production method provided by the invention. The method for producing the fully-biodegradable material comprises the following steps: (a) designing a preparation scheme; (b) getting ready for preparation; (4) analyzing a formula; (d) grafting and modifying bamboo cellulose; (e) fusing; (f) mutually mixing at a high speed; (g) extruding. The fully-biodegradable material produced by the method is fully-biodegradable, environment-friendly, free of toxicity and good in processing performance, and can be directly prepared into various semi-finished products and finished products without adding auxiliary materials. Meanwhile, the bamboo cellulose is fused into the fully-biodegradable material, so that the strength of the fully-biodegradable material is enhanced.

Description

technical field [0001] The invention relates to a device and a method for producing fiber-filled starch-based fully biodegradable materials. Background technique [0002] With the acceleration of people's pace of life and the improvement of living standards, the amount of disposable plastic packaging bags and packaging films is increasing. The use of a large number of disposable plastic packaging films and packaging bags has caused huge pollution to the environment. On the one hand, disposable shopping bags and packaging films are scattered everywhere along the railway and tourist attractions, giving people visual pollution and affecting the ecological environment of scenic spots; "white pollution". Therefore, how to solve the environmental pollution problem of waste packaging film and mulch film is a difficult problem that needs to be solved urgently in front of governments and scientific and technological workers from all walks of life. [0003] It is imperative to seek...
