Polyamide-based composite material with fragrant odor and flocking imitation effect and preparation method thereof

Abstract

The invention discloses a polyamide-based composite material with a fragrant odor and a flocking imitation effect and a preparation method thereof. The polyamide-based composite material is mainly comprises 10-20 parts of modified green tea powder functional masterbatch, 76-89 parts of polyether ester resin (PET-PEG graft) and 1-4 parts of auxiliary agents such as an antioxidant and the like. According to the preparation method, the superfine natural green tea powder which is surface-treated with polyethylene glycol (PEG) is blended and extruded with the polyether ester resin (PET-PEG graft) to prepare the modified masterbatch, and then the composite material is prepared by subjecting the functional masterbatch, polyamide resin, the auxiliary agents and the like to blending extrusion. Since the green tea powder itself has a natural green tea scent, a part prepared from the composite material has the green tea scent. In addition, due to the adoption of dark green tea powder as a filler,a large amount of dark spots appear on the surface of the part, prepared from the composite material through color-matching processing, in light colors such as beige or gray, wherein the composite material is prepared from the green tea powder, therefore, a similar flocking effect is achieved.

Description

technical field [0001] The invention relates to a functional polyamide material and a preparation method thereof, in particular to a polyamide functional master batch with a delicate smell and a flocking effect and a preparation method of a composite material thereof, belonging to the technical field of polyamide. Background technique [0002] Polyamide materials have excellent mechanical properties, high strength, and good heat resistance, and are widely used in many fields such as automobiles, machinery, chemicals, and electronics. However, after conventional polyamide materials are melted and extruded at high temperature, the parts prepared from them have poor odor due to the thermal degradation of macromolecular segments, which affects their application in related fields, especially automotive interior materials and indoor furniture. materials etc. At present, relevant experts and scholars at home and abroad have done some research on the improvement of the odor of poly...

AI Technical Summary

Problems solved by technology

In the final analysis, the above two methods to improve the odor of polyamide materials are to reduce the content of residual monomers and oligomers in the material as much as possible through physical and chemical means to achieve the improvement of the odor of the material, mainly focusing on the improvement of the odor intensity. The type of material smell is not obvious, and the prepared material still has the peculiar glue smell of plastic

[0003] At present, there is no report on polyamide composite materials with imitation flocking effect
