Abstract

The invention discloses a bio-based degradable flame-retardant polylactic acid engineering material and a preparation method thereof. The engineering material is prepared by fusion and mixing of polylactic acid, liquor vinasse after surface treatment and high-molecular type phosphorus-containing fire retardant. The mass percent of polylactic acid, the liquor vinasse after surface treatment and the high-molecular type phosphorus-containing fire retardant is 70:(30-5):(0-25). The engineering material has the advantages of simple formula, improved flame retardation efficiency, and excellent mechanical properties of the original material; a stable compact carbon layer is generated during combustion, and droplet phenomenon is effectively inhibited.

Description

technical field

[0001] The invention relates to the technical field of flame retardancy and reinforcement of polylactic acid materials, in particular to a bio-based degradable flame-retardant polylactic acid engineering material and a preparation method thereof. Background technique

[0002] Biodegradable material is a new type of material developed after the 1980s with the prominent contradictions of environment and energy. As a naturally degradable material, it plays a unique role in environmental protection. Its research and development have been be developed rapidly. Among them, polylactic acid is the most well-known biodegradable material, which is made of starch raw materials proposed by renewable plant resources (such as corn), and can be completely degraded by microorganisms in nature after use, without polluting the environment. Furthermore, polylactic acid has good mechanical and physical properties, and can be applied to various processing methods such as blow mo...
