Problems solved by technology

[0004] The heating is carried out in the transmission channel, and the above-mentioned mixing will cause carbonization of the bamboo fiber material in the transmission spiral channel due to high temperature heating, which destroys the original properties of the bamboo fiber
[0005] Secondly, the above-mentioned existing composite materials are all molded by injection molding. Injection molding needs to have certain requirements on the viscosity of the heated material. If it is too viscous, injection molding cannot be performed, and the amount of bamboo fiber added is limited limitation, that is, the cost of the main material is relatively high

Abstract

The invention belongs to the technical field of composite material processing, and in particular relates to a molding method of a bio-based filler-modified polylactic acid composite product. It solves the technical problems such as easy carbonization of bamboo fibers in the prior art. The granulation process of the polylactic acid bamboo fiber composite material comprises the following steps: S1, material preparation; S2, feeding; S3, heating; S4, extruding; S5, cutting; S6, die-casting. The present invention has the advantages of: it can prevent the carbonization of bamboo fiber material caused by long-time high-temperature heating in the conveying channel, and improve the product quality; at the same time, because the path through the conveying channel is shortened, the amount of bamboo fiber added can be increased to reduce The cost of producing the main material.

Description

technical field [0001] The invention belongs to the technical field of composite material processing, and in particular relates to a molding method of a bio-based filler-modified polylactic acid composite product. Background technique [0002] Polylactic acid, bamboo fiber and auxiliary materials can be mixed to produce environmentally friendly materials, which are used in various tableware and other food fields. [0003] When various materials are mixed, the current material mixing is concentrated in one place and then heated to produce the final composite material. [0004] Heating is carried out in the transmission channel, and the above-mentioned mixing will cause carbonization of the bamboo fiber material in the transmission spiral channel due to high temperature heating, which destroys the original performance of the bamboo fiber. [0005] Secondly, the above-mentioned existing composite materials are all molded by injection molding. Injection molding needs to have ce...
