Embodiment 1

[0018] The specific preparation process of the luminous plastic cup mentioned in the present invention is as follows:

[0019] a) Manufacture the cup body. The material of the cup body is PC, which is prepared by extrusion molding process; the prepared cup body is divided into an outer layer and an inner layer, and the middle layer between the two layers is a cavity structure; the thickness of the outer layer is about The thickness of the inner layer is about 0.6mm, the thickness of the inner layer is about 1mm, and the thickness of the middle layer is about 0.7mm; the upper end surface of the cup body is closed, and the lower end surface is provided with injection holes and vent holes, and the hole diameters are 0.7mm and 0.5mm respectively. The injection molding process of the middle layer is more stable, and it is conducive to the adhesive connection between the cup body and the base;

Abstract

The invention discloses a preparation method of a color-changing plastic cup. The preparation method comprises the following steps: (a) manufacturing a cup body; (b) preparing a color-changing material; (c) carrying out injection molding on the color-changing material; (d) sealing and drying; (e) bonding a base; and (f) performing post treatment. According to the preparation method of the color-changing plastic cup, procedures are reasonably arranged, the preparation process is simple and convenient, the cost is moderate, a manufactured cup body is in a multi-layer structure design, a middle layer between an inner layer and an outer layer is a thermosensitive color-changing layer which can change with different colors according to the water temperature in the cup body, and the appearance performance and the interestingness of the plastic cup are effectively enriched; the plastic cup has the reasonable design and material selection, has the stable safety performance during use, and has the durable and remarkable color-changing effect.

Description

technical field [0001] The invention relates to a method for preparing a plastic cup, in particular to a method for preparing a plastic cup that can change the color of the cup body following water temperature, and belongs to the technical field of plastic products. Background technique [0002] Plastic cups are commonly used utensils for drinking water in people's lives. Based on their light texture, beautiful appearance, low cost and strong plasticity, they are deeply loved by people. [0003] But the form of existing plastic cup is single, and its color can't be changed after the cup body molding, has limited the outward appearance performance of plastic cup, can't satisfy the use needs of fashion crowd. Contents of the invention [0004] In view of the above needs, the present invention provides a method for preparing a color-changing plastic cup. The preparation method has a reasonable process arrangement, and the prepared cup body is designed with a multi-layer struc...
