Embodiment

[0019] The invention discloses a two-color radiant lip gloss tube secondary rubber encapsulation process, which is used for producing the tube body of the lip gloss tube. The process is simple and the production cost is low.

[0020] The present invention specifically comprises the following steps:

[0021] Step 1, the inner layer of the pipe body is injection molded by PMMA plastic. The barrel temperature of PMMA plastic injection molding is 260-270°C, the mold temperature is controlled at 90-115°C, the injection pressure is 150-180MPa, and the residence time is 2-3min.

[0022] Step 2, apply a UV paint layer on the inner surface of the pipe. Specifically, first spray UV paint on the inner surface of the tube body, then dry it by infrared rays, the drying temperature is 60-65 °C, and the drying time is 3 minutes, and then cool and level up to 20-25 °C for exposure UV curing.

[0023] In step 3, the outer layer of the pipe body is injected with PC plastic outside the inner l...

Abstract

The invention discloses a secondary encapsulation process of a two-color lip gloss tube, which is characterized in that it comprises the following steps: step 1, injecting the inner layer of the tube body through PMMA plastic; step 2, coating the surface of the inner layer of the tube with UV paint layer; step 3, injecting the outer layer of the pipe body through PC plastic outside the inner layer of the pipe body to form a transparent secondary injection molding coating layer; step 4, water transfer printing chameleon paint layer on the surface of the secondary injection molding coating layer. The invention has simple process, low production cost, and the produced lip gloss tube body has good structural strength, good wear resistance, good solvent resistance, good three-dimensional effect and good appearance effect.

Description

technical field [0001] The invention relates to the field of cosmetic container production, in particular to a secondary encapsulation process of a two-color lip gloss tube. Background technique [0002] Lip gloss is a cosmetic applied to the lips in a viscous liquid state. The pigments of lip gloss are organic pigments or minerals, which give lip gloss different colors. After application, it can keep the lips moist and have a strong three-dimensional effect. At the same time, the lip gloss can not be kept on the lips for too long, and it is easy to take off makeup. It is necessary to carry the lip gloss with you for easy makeup touch-ups, which is very suitable for consumers who need light makeup. [0003] Lip gloss is usually packaged in a tube container. With the improvement of people's quality of life, lip gloss tubes that are simply used as containers can no longer meet people's needs. People are constantly pursuing design innovations to meet visual, tactile and funct...
