Abstract

The invention relates to a long-acting weather-resistant color master batch and a preparation method thereof. The preparation method comprises the following steps: 45 to 65 percent of high density polyethylene, 4 to 6 percent of antioxidant, 1 to 3 percent of zirconia, 2 to 5 percent of ultraviolet absorber, 3 to 5 percent of dispersant, 5 to 10 percent of hindered amine light stabilizer, 15 to 25percent of titanium dioxide and 1 to 10 percent of pigment are uniformly mixed to obtain a mixed material, the mixing time is 15 to 20 minutes, and the mixing temperature is 40 to 50 DEG C; then, themixed material is added into an extruder for melt extrusion to obtain the long-acting weather-resistant color master batch. The long-acting weather-resistant color master batch of the invention has good compatibility with high-density polyethylene, and can not only protect the C-C main chain of the high-density polyethylene from being destroyed by high energy radiation under the action of ultraviolet light energy, but also can be used as a kind of toughening agent to further improve the overall mechanical properties of modified high density polyethylene.

Description

technical field [0001] The invention belongs to the field of macromolecules, and in particular relates to a long-acting weather-resistant masterbatch and a preparation method thereof. Background technique [0002] High-density polyethylene material (HDPE) is white granular, non-toxic, tasteless, odorless, with high crystallinity (above 80%) and high density (0.941~0.960g / cm 3 ), the relative molecular mass is often hundreds of thousands to hundreds of thousands, with high rigidity and toughness, excellent mechanical properties, good solvent resistance, steam permeability, etc., and is widely used in various fields. The buoy produced by high-molecular-weight high-density polyethylene material is not only light in weight, high in buoyancy, acid and alkali resistance, zero maintenance, flexible in combination and transformation, long in life, bright in color and beautiful in appearance, but also anti-corrosion, anti-freeze, and free from sea water and chemicals. , Chemicals, o...
