Problems solved by technology

Different plastic casings of an electronic product sometimes need to be decorated with different colors to achieve a better appearance and visual effect. However, most of the plastic particles on the market can only be made into one color, and multiple colors require It is realized by molding plastic particles of various colors separately, and there is rarely a material that can be injection molded into different colors

Abstract

The invention relates to a composition capable of being processed and molded into various colors and a preparing method thereof. The composition is prepared from, by weight, 100 parts of a polymer, 1-3 parts of a thermosensitive aid, 0.1-1 part of a color developing agent and 0-2 parts of organic toner. According to the composition, by adding the color developing agent and the thermosensitive aid,the material can be molded into plastic products of various colors at multiple molding temperatures, the purpose can be achieved simply at a low temperature, and therefore, the organic toner can be prevented from being decomposed at a high temperature. The preparing method is simple, colors are diversified, and the method is economical and practical and has a good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of plastic modification, and in particular relates to a composition capable of being processed into various colors and a preparation method thereof. Background technique [0002] Plastic products can be seen everywhere in people's daily life, and many plastic products need to be made into specified colors according to customer requirements to meet the requirements of beautifying the appearance design. Different plastic casings of an electronic product sometimes need to be decorated with different colors to achieve a better appearance and visual effect. However, most of the plastic particles on the market can only be made into one color, and multiple colors require It is achieved by molding plastic particles of various colors separately, and there is rarely a material that can be injection molded into different colors. Contents of the invention [0003] The technical problem to be solved by the present inv...
