[0039]

[0040] The weather-resistant masterbatch UV-7308PP5 applied to automotive PP materials is prepared by the following method:

[0041] (1) The components of light stabilizer 3853 were mixed, and stirred in a high mixer at a stirring speed of 700 rpm for 5 minutes at a temperature of 25°C.

[0042] (2) After the light stabilizer 3853 is heated and turned into a liquid state, it is added through a liquid oil pump and enters a twin-screw extruder for granulation. The temperature of the middle section of the barrel is set at 210-230°C, and the temperature of the front section of the barrel of the extruder is set at 160-170°C. The strips extruded by the twin-screw extruder are cooled by tap water at normal temperature and dried by hot air. Then cut into pellets.

Abstract

The invention belongs to the technical field of high polymer material processing aids, and discloses a weather-resistant master batch UV-7308PP5 as well as a preparation method and application thereof. The weather-resistant master batch UV-7308PP5 comprises the following components in percentage by mass: 20%-40% of a light stabilizer 3853, 10%-30% of a light stabilizer 2908; 30%-50% of PP resin; 2%-10% of polypropylene wax; 0.1%-0.1% of a main antioxidant; and 0.1%-0.5% of an auxiliary antioxidant. According to the present invention, the proper polypropylene wax is added, such that the precipitation of the light stabilizer 3853 can be avoided by improving the melt strength of the master batch so as to avoid the agglomeration, the agglomeration and the precipitation do not need to be prevented through the coating of the film, and the advantages of simple process, low cost and the like are provided.

Description

technical field [0001] The invention belongs to the technical field of processing aids for polymer materials, and in particular relates to a weather-resistant masterbatch UV-7308PP5 and its preparation method and application. Background technique [0002] When polymer materials are exposed to sunlight outdoors, a series of complex phenomena will occur due to the absorption of ultraviolet light. This process is often called photoaging, which is essentially the result of various physical and chemical changes in polymer chains. Photoaging is easy to cause various phenomena such as appearance fading, surface cracking, and mechanical and electrical performance degradation of polymer materials. Photoaging is one of the important reasons for the aging phenomenon of polymer materials in the application process. Adding a light stabilizer during the polymerization and processing of polymer materials can effectively slow down the photoaging of polymer materials caused by ultraviolet r...
