Problems solved by technology

[0005] At present, there are relatively few literatures and patents on the antistatic modification of biodegradable materials, and they all add a single antistatic agent, such as patent CN200580046939.8 and patent CN201110394987.6. There are few two antistatic agents compounded to prepare antistatic biological Literature and patents on degradable materials

Abstract

The invention belongs to the field of biodegradable materials and relates to a flame retardant and anti-static biodegradable material, and a preparation method thereof. The biodegradable material is prepared by the following components by weight: 5-90 parts of a biodegradable resin, 0-10 parts of a reactive agent and 5-90 parts of flame retardant and anti-static starch master batch. By compounding an organic anti-static agent and an inorganic anti-static agent, a durable anti-static property is endowed to the biodegradable material; and dependency of the anti-static property to environment humidity is reduced. Meanwhile, by adding an intumescent flame retardant with the starch as a carbon source, inflammability of the biodegradable material is effectively overcome. The anti-static agent and the intumescent flame retardant are environment-friendly; and excellent mechanical properties and processing properties of the biodegradable material are retained.

Description

technical field [0001] The invention belongs to the field of biodegradable materials, and relates to a flame-retardant and antistatic biodegradable material and a preparation method thereof. Background technique [0002] Biodegradable materials are widely used in various industries, mainly including environmental protection materials, packaging materials and medical materials, which can partially replace traditional plastics. However, biodegradable materials, like traditional plastics, have excellent electrical insulation and high resistivity, and are prone to accumulate static charges during production and application to generate static electricity, causing some hazards or accidents. Therefore, it is imperative to eliminate static electricity and reduce resistivity of biodegradable materials. At the same time, the flammability of biodegradable plastics also greatly limits its safe and effective application. [0003] In order to eliminate the static electricity of the mate...
