Problems solved by technology

[0003] The existing cosmetic pen packaging has unstable static friction and uneven dynamic friction during the long-term static friction and dynamic friction process, and the product is easy to wear and deform. At the same time, due to the diversified requirements of the product, there are higher requirements for the structure of the pen: 1. Need More excellent mechanical properties support; 2. Better surface activity is needed for product surface painting, bronzing, printing, etc.; 3. Better coloring ability is needed, so that the material itself is conducive to dye dispersion to achieve a good color effect

Embodiment 1

[0026] A method for preparing a special polymer material for cosmetic pencil packaging, comprising the steps of:

[0027] (1) Preparation of raw materials: In parts by weight, it includes 75 parts of acrylonitrile-butadiene-styrene plastic, 10 parts of polycarbonate, 1 part of liquid dispersant, 1 part of compatibilizer, 1 part of solid dispersant, lubricating 5 parts of agent, 1 part of black powder;

[0028] (2) After drying the acrylonitrile-butadiene-styrene plastic and polycarbonate at 90~100℃ for 3~4 hours, set aside;

[0029] (3) Add the raw materials sequentially and blend evenly, mix them in a high-speed mixer for 10-15 minutes, then send them to a twin-screw extruder for full plasticization and blending, extrude, cool, granulate, and dry to obtain polymers Material.

[0030] Among them, the acrylonitrile-butadiene-styrene plastic used uses plate-grade materials to provide mechanical support and alleviate the mechanical decline caused by multi-components. The specif...

Abstract

The invention discloses a preparation method for a high polymer material special for cosmetic brush packaging. The preparation method comprises the following steps that 1, raw materials are prepared;2, acrylonitrile-butadiene-styrene plastic and polycarbonate are dried for 3-4 hours at the temperature of 90-100 DEG C and then used for a standby; 3, the raw materials are added in sequence, evenlymixed for 10-15 minutes in a high-speed stirring machine and fed into a twin-screw extruder for sufficient plastification and mixing, and extrusion, cooling, granulation and drying are conducted to obtain the high polymer material. The high polymer material prepared by using the preparation method has the advantages that the static friction of the product is stable, the dynamic friction is uniform, and the product is not prone to abrasion or deformation. According to diversified requirements for the product, more requirements for the structures of the brushes need to be supported by more excellent mechanical properties, and better surface activity is needed for surface painting, gold stamping, printing and the like; due to a better coloring ability, the material facilitates dye dispersion,and a very good color effect is achieved.

Description

technical field [0001] The present invention relates to the technical field of polymer materials, in particular to a method for preparing a special polymer material for cosmetic pencil packaging. Background technique [0002] With the development and progress of the industry, cosmetic pencils have different components of paste, packaging structure and appearance design. The main body is environmentally friendly, high gloss, multi-color, smooth to the touch, and long-term use and aging resistance. The materials commonly used in the market are currently mainly aimed at the characteristic requirements of high gloss. For example, 718 material is a black high-gloss cosmetic pencil material, which has no firmness of spray paint, no lubrication of hand feeling, and no insertion force during repeated use of cosmetic pens. Uniformity and special wear resistance requirements of product bonding parts. Some cosmetic pens are pluggable, this is static friction, some cosmetic pens are ro...
