A kind of plastic product and production process of ultraviolet light changing color

Abstract

The invention relates to a plastic product and a production process for ultraviolet color-changing. The manufacturing process adds polypropylene (molecular formula c3h6ncas) and high-temperature fluorescent pigments by weight and stirs for 5 minutes, and then adds ultraviolet color-changing powder according to the principle of red, yellow and blue color matching, and stirs. It takes 5 minutes to obtain the ultraviolet color-changing thermoplastic resin with secondary color, and then inject the ultraviolet color-changing thermoplastic resin with an injection molding machine at a temperature of about 190°C to produce various ultraviolet color-changing handicrafts, accessories, daily necessities, toys and other products. The product can be changed into another color after being irradiated with ultraviolet light. This invention overcomes the problem that the ultraviolet color-changing plastic products produced before can only change from white to other colors. Its process is simple, convenient, and low in cost. Non-toxic, tasteless, heat-resistant, not affected by humidity and other characteristics, make the product novel, colorful and beautiful, more widely used, and the market prospect is very broad.

Description

technical field [0001] The invention relates to the technical field of injection molding of plastic products, in particular to a plastic product and a production process of ultraviolet light-changing color. For example, when the product is irradiated with ultraviolet light outdoors, it can change from the original color to another color, and the color can be matched according to the color. Different presentations, such as blue to green, red to blue, orange to red, etc., the product is rich in color, practical, and achieves an interesting ultraviolet color changing effect. Background technique [0002] With the continuous improvement of people's living standards, the consumption awareness of health care continues to increase, and the strong publicity of anti-ultraviolet products in cosmetics, accessories and other industries has made consumers increasingly demanding for anti-ultraviolet products and measuring them. Not only does it require environmental protection of its mater...

Problems solved by technology

[0003] The ultraviolet discoloration plastic products I produced before can only be white without ultraviolet light indoors. Under the outdoor ultraviolet light, they will turn blue, purple, red, yellow, orange, sky blue, and the product has no ultraviolet light. When irradiated, the white color of the product itself cannot reflect the aesthetic feeling, and the color is not rich enough, giving people the impression that it is a low-end product
