Problems solved by technology

[0003] The most commonly used in the prior art is by coating or adhering materials with fluorescence or luminous, although this method endows the parts with night indication to a certain extent, but the wear resistance of the coated or adhering luminous parts Poor performance, unable to meet the long-term indication function, and the production process is complicated and the production cost is high
In addition, there are methods such as adding fluorescent powder directly to raw materials to give fluorescent properties to parts. For example, patent CN105968579 discloses a polypropylene composite material with indicating function and low VOC toxicity. The fluorescent material prepared by this method, if you want to To achieve a certain fluorescent effect, the amount of phosphor added is as high as 8 to 16 parts, resulting in high raw material costs and low product market competitiveness

Abstract

The invention discloses a polypropylene composite material with a fluorescent effect and a preparation method thereof. The polypropylene composite material is composed of the following components in parts by weight: 5 to 10 parts of polypropylene functional master batch with a fluorescent effect, 45 to 95 parts of normal polypropylene, 0 to 40 parts of inorganic filling material, 0 to 20 parts ofelastomer, 2 to 5 parts of antioxidant, and 0 to 3 parts of other auxiliary agents. The composite material has a good fluorescent effect, at the same time, the using amount of fluorescent functional auxiliary agents is reduced, the material cost is reduced, and the fluorescent effect of parts is enhanced.

Description

technical field [0001] The invention relates to a low-cost, high-efficiency fluorescent polypropylene functional masterbatch and a preparation method thereof, belonging to the technical field of polypropylene. Background technique [0002] Due to its low density, high cost performance, excellent heat resistance and easy molding process, polypropylene has become one of the most used and fastest growing plastic varieties in automotive plastics. However, with the rapid development of the automobile industry in recent years, quality, lightweight, energy saving, environmental protection, and low cost have become the main goals of the current automobile industry. For example, on the basis of the existing modified polypropylene materials, other functions, such as fluorescence and luminous properties, are given to make the parts prepared have nighttime indicator functions. [0003] The most commonly used in the prior art is by coating or adhering materials with fluorescence or lumi...
