Abstract

The invention discloses an anti-oxidative color masterbatch. The anti-oxidative color masterbatch comprises the following raw materials in percentage by weight: 10-70% of pigment, 1-22% of antioxidant composition, 5-30% of dispersion and lubrication agent, 20-60% of carrier resin and 0-15% of filler, wherein the antioxidant composition comprises a hindered phenolic antioxidant and one or more of a phosphite antioxidant, a thio antioxidant and a light stabilizer. The invention further discloses a preparation method and application of the anti-oxidative color masterbatch. The anti-oxidative color masterbatch disclosed by the invention has the advantages of good uniformity, good stability, good processability, good mobility and good heat and weather resistance; the preparation method of the anti-oxidative color masterbatch has the advantages of simplicity, no pollution to factory buildings and no pollution to operating personnel; and during use, the dispersion is easy, the adding dosage is small, the service lives of plastic products can be prolonged remarkably, the brightness of colors of the plastic products can be increased, and the fading time of the plastic products can be delayed.

Description

technical field [0001] The invention relates to the field of color masterbatches, in particular to an anti-oxidation color masterbatch and its preparation method and application. Background technique [0002] Plastics are synthesized from raw materials such as petroleum, natural gas or coal, and can be produced on a large scale. Plastic products are easy to form and process. Therefore, plastics can be made as smooth as silk, as strong as steel, as light as sponge, and as transparent as glass. Plastic products can replace traditional materials and fill every corner of the world. Plastic is an important material in daily life, and its application fields are constantly expanding. However, whether it is natural or synthetic, polymer materials are prone to oxidation reactions. The degradation of polymers due to the reaction with oxygen in the air during preparation, processing, storage and use is called thermo-oxidative degradation. The research on the thermal oxygen degradatio...
