Blended foam material based on polycaprolactone (PCL) and modified polylactic acid (PLA) and preparation method thereof

Abstract

The invention discloses a blended foam material based on PLC and modified PLA and a preparation method thereof, and belongs to the foam material field. The foam material comprises, by weight, 60-90 parts of PLA, 1-25 parts of PCL, 2-10 parts of reinforcing agents, 1-3 parts of nanometer nucleating agents, 4 parts of foaming agents, 0.1-1 part of a blowing promoter, 1-3 parts of environment-friendly flame retardants and 0.5-1 part of a surfactant. According to the foam material and the preparation method thereof, composite foamed plastics with good mechanical properties and superior surface quality can be prepared.

Description

technical field

[0001] The invention belongs to the field of foaming materials, and in particular relates to a polycaprolactone-modified polylactic acid-based blended foaming material and a preparation method thereof. Background technique

[0002] The raw material of traditional plastics is petroleum, and the products are non-degradable and will cause serious pollution to the ecological environment. The raw materials of polylactic acid (PLA) are plants, and the products are biodegradable, environmentally friendly and save petroleum resources. Polylactic acid products have been widely used in medical plastics such as artificial bones; instead of ordinary plastics, they are used in short-term use products, such as garbage bags, disposable packaging supplies, daily necessities, etc.; in recent years, they have replaced engineering plastics in long-term use products, such as automobiles products, home improvement products, etc. trends.

[0003] At present, the main factors rest...
