A vehicle exterior trim with fluorescent effect and preparation method thereof

Abstract

The invention relates to the technical field of vehicle exterior trims, in particular to a vehicle exterior trim with a fluorescent effect. The formula of the vehicle exterior trim consists of the following ingredients in parts by weight: 100 parts of PMMA or ASA resin, 0.2-0.35 parts of lubricant , 5.5-7.0 parts of toughening agent, 0.15-0.28 parts of transparent black pigment, 2.8-3.5 parts of fluorescent agent, 0.2-1.0 parts of dispersant and 0.4-0.5 parts of antioxidant. The invention also relates to a preparation method of the vehicle exterior decoration with fluorescent effect. After adding transparent black pigment and fluorescent agent to the formula, the vehicle exterior parts prepared by injection molding process can not only appear black to achieve the versatile effect of vehicle models, but also can be used in dim light or dark after absorbing light or other electromagnetic radiation. It emits visible light in an environment that is visible to the human eye, helps drivers and pedestrians identify passing vehicles, and promptly reminds drivers and pedestrians to pay attention to safety, thereby greatly improving the safety of vehicles; the preparation process of the present invention is simple and easy, and is conducive to industrial production .

Description

Technical field: [0001] The invention relates to the technical field of vehicle exterior trims, in particular to a vehicle exterior trim with fluorescent effect. [0002] The present invention also relates to a method for preparing the above-mentioned vehicle exterior trim with fluorescent effect. Background technique: [0003] With the rapid development of the automobile industry and the continuous improvement of people's living conditions, automobiles have become one of the indispensable means of transportation for people to travel. The number of cars is increasing year by year, and more and more people own private cars. The popularization of cars has brought development to the manufacture and design of auto parts. Due to the complex structure of the car, the range of parts involved is very extensive and complex. Therefore, it is necessary to ensure that the structure of each part is reasonable and the strength meets the requirements. New innovations can be made to meet m...

Problems solved by technology

However, when the vehicle is in a dark environment, except for the lights (running lights, brake lights, fog lights, etc.), the rest of the exterior parts cannot be clearly identified by people, and are easily touched by other vehicles, causing damage to the vehicle

That is to say, the functions of these existing vehicle exterior trim parts are relatively single, and further improvement is still needed.
