Color masterbatch for black ultraviolet(UV) resistant nylons

Abstract

The invention discloses a color masterbatch for black ultraviolet (UV) resistant nylons. The color masterbatch comprises the following components: 15% to 35% of black colorants, 25% to 35% of polyamide, 5% to 15% of composite stabilizers, 20% to 30% of damp removing agents, and 3% to 10% of dispersants, wherein the composite stabilizers at least comprise two of hindered phenol antioxidants, phosphite antioxidants, copper halide stabilizers, hindered amine light stabilizers, hydrolysis resistance agents, benzophenone and benzotriazole ultraviolet absorbents. Compared with the prior art, the invention mainly adopts the composite preparation of a plurality of stabilizers, various stabilizers generate synergistic effect, the stability of materials during processing and outdoor long-term use is guaranteed, the mechanical properties of the materials are better, and therefore, the color masterbatch is suitable for designing and applying high-end nylon products with the requirement of long-term weathering resistance. Moreover, the damp removing agents which have the effect of removing water in plastic are added to the color masterbatch, so as to further improve the properties of the nylons.

Description

technical field [0001] The invention belongs to the technical field of plastic coloring, in particular to a color masterbatch for black anti-UV nylon. Background technique [0002] Color masterbatch is a new plastic and fiber coloring product developed in the 1960s. It is a polymer compound prepared by uniformly loading pigments in resins. The masterbatch is mainly composed of three parts: colorant, carrier and dispersant. [0003] According to relevant information, the average annual growth rate of demand for color masterbatch in other countries in Asia is about 7%-9%, but the average annual growth rate of demand for color masterbatch in my country is about 20%. China is expected to become the fastest growing market for masterbatch demand. Especially for color and additive masterbatch, our country has to rely on imports. my country has become the largest producer and consumer of masterbatch in Asia. Relevant experts believe that in the future, masterbatches will develop...
