Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an anti-ultraviolet color masterbatch for polypropylene and a preparation process thereof. Background technique [0002] At present, the coloring methods for producing plastic products mainly include toner coloring, dyeing and pulling grain coloring and color masterbatch coloring. When directly using toner for coloring, coloring is very simple, but its biggest disadvantage is that the pigment will fly up during transportation, storage, weighing, and mixing, causing pollution, seriously affecting the environment, and prone to color spots and color differences that are difficult to control. Dyeing and pelletizing coloring is to mix plastic raw materials and toners and then use mixing equipment such as twin-screw extruders for melt blending and coloring. Compared with coloring with toners, the coloring effect of pelletizing has been greatly improved, but plastic needs After two hea...
