Abstract

The invention relates to the technical field of cosmetic packing materials, in particular to a preparation process of an antibacterial and antioxidant PBT (polybutylene terephthalate) double-color cosmetic packing material. Firstly, antibacterial ingredients are extracted from trollius chinensis, rhizoma coptidis and radix notoginseng, and a natural antibacterial agent is prepared; then, PBT, a natural antioxidant, a toner, a plasticizer and the natural antibacterial agent are mixed and subjected to extrusion granulation through an injection molding machine, and antibacterial and antioxidant PBT master batch is prepared; finally, the antibacterial and antioxidant PBT double-color cosmetic packing material is prepared with a double-color injection molding process. A double-color mold process is used to replace a conventional laser etching process to color the double-color cosmetic packing material, the production process is simplified, and the prepared cosmetic packing material is richin color, bright in luster, good in antibacterial and antioxidant property and applicable to products such as lipstick tubes, lip gloss, eyelash and eyeliner tubes, cushion boxes, rouge pressed powderboxes, eyeshadow boxes, face powder boxes and the like.

Description

technical field [0001] The invention relates to the technical field of preparation of cosmetic packaging materials, in particular to a preparation process of an antibacterial and anti-oxidation PBT double-color cosmetic packaging material. Background technique [0002] Butylene terephthalate (PBT) has excellent mechanical, electrical, chemical corrosion resistance, easy molding, low moisture absorption, and friction resistance. It is an engineering plastic with excellent comprehensive properties. As one of the application directions of plastics, cosmetic packaging materials put forward higher requirements for antibacterial, anti-oxidation and color. With the development of multi-color plastic products, when single-color injection molding machines are used for molding, the subsequent processing procedures are time-consuming, laborious and complicated, and this subsequent processing technology affects the quality of plastic products, so this process is no longer sufficient for...
