Abstract

The invention belongs to the technical field of high polymer materials, and particularly relates to a color master batch with an anti-ultraviolet function and a preparation method of the color master batch. The color master batch comprises the following components in parts by weight: 30-50 parts of linear low-density polyethylene, 20-40 parts of toner, 2-10 parts of a composite ultraviolet light absorber, 2-10 parts of a light stabilizer GW540, 2-10 parts of a composite antioxidant, 10-15 parts of a dispersant and 10-15 parts of a lubricant. Wherein the composite ultraviolet light absorber is a mixture of an ultraviolet light absorber UVP327, an ultraviolet light absorber RMB and nano titanium dioxide; the composite antioxidant is a mixture of an antioxidant 1010 and an antioxidant 168. The composite ultraviolet light absorber, the composite antioxidant and the light stabilizer GW540 form a matching relationship, so that the ultraviolet aging resistance of the color master batch is improved together, and the service life of a product prepared from the color master batch is prolonged.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a color masterbatch with an anti-ultraviolet function and a preparation method thereof. Background technique [0002] Masterbatch is a new type of special colorant for polymer materials, also known as pigment preparations, mainly used in plastics. The color masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading super-normal pigments in the resin. It can be called a pigment concentrate, so its coloring power is higher than that of the pigment itself. Mixing a small amount of color masterbatch and uncolored resin during processing can achieve the colored resin or product with the designed pigment concentration, which has a wide range of application values. However, the products produced by the existing masterbatches are not resistant to ultraviolet rays and are prone to aging defects. For examp...
