Abstract

The invention provides a preparation method of a PLA composite material used for baby bath, which comprises the following steps: 1)adding nano attapulgite and nano mica powder in a high speed mixer for stirring for 10 minutes, dissolving a silane coupling agent in ethanol and then adding into the high speed mixer in a spray form, stirring for 30 minutes and then discharging, drying to obtain the modified nano powder; 2)placing PLA, an anti-oxidant, a flexibilizer, a cross-linking agent and a lubricant in a drying box for drying, adding with the modified nano powder in the high speed mixer for uniformly mixing to obtain a mixture; 3)adding the mixture in the step 2) into a double screw extruder for extruding and granulating to obtain the pellet; and 4)placing the pellet in a drying box for drying to obtain the PLA composite material used for the baby bath. The produced material has the advantages of good toughness, impact resistance and thermostability, is friendly to environment, and is adapted to baby bath manufacture.

Description

Technical field:

[0001] The invention relates to a preparation method of a PLA composite material used for baby bathtubs. Background technique:

[0002] PLA is the English abbreviation of the biodegradable plastic polylactic acid, which is full written as: polylactic acid, also known as polylactide (polylactide), which belongs to polyester. PLA is a polymer obtained by polymerizing lactic acid as the main raw material. It mainly uses corn and cassava as raw materials. The source of raw materials is sufficient and renewable. Green and environmentally friendly polymer materials. PLA material has good biocompatibility, gloss, transparency and hand feeling, and also has certain bacteria resistance, flame retardancy and UV resistance, so it can be used to make baby products, but its toughness and impact resistance Poor, poor thermal stability, so not suitable for making baby bathtubs. Invention content:

[0003] The technical problem to be solved by the present invention is ...
