Abstract

The invention belongs to the field of polymer and relates to an acid-resistant anti-aging flame-retardant color masterbatch with excellent properties and a preparation method of the color masterbatch. The color masterbatch is prepared and processed by using a polyethylene carrier, an inorganic or organic toner, a stabilizer NOR and a dispersant. The color masterbatch has a good compatibility and a coloring effect for polyethylene products, and has an excellent flame-retardant effect with the flame-retardant level reaching V-2 level. Moreover, the color masterbatch is rich in colors and good in surface gloss. The colored products do not fade easily even in an environment with the pH value between 2 and 4.

Description

technical field [0001] The invention belongs to the field of macromolecules, and relates to a composition and a preparation method thereof, in particular to a color masterbatch with excellent flame retardancy and anti-aging under acidic conditions and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the aesthetic requirements for plastic products are getting higher and higher. Correspondingly, the demand for plastic coloring is stronger. [0003] Plastic coloring is to mix and granulate the natural color resin and colorant to form colored plastics, which are then used in the molding process. [0004] The traditional plastic coloring is dry powder coloring. That is to say, the powdery colorant and the natural color resin are evenly mixed and used to make plastic products directly. Its disadvantage is that it has poor compatibility with the natural color resin, poor stability, and the flying colorant will cause en...
