Abstract

The invention provides a coupling anti-oxidation special color master batch for a barrier bottle and a preparation method of the coupling anti-oxidation special color master batch. The coupling anti-oxidation special color master batch comprises, by weight, 10-50 parts of high-density polyethylene, 10-20 parts of low-density polyethylene, 3-6 parts of low-density linear polyethylene, 10-40 parts of pigment toners, 1-5 parts of titanate coupling agents, 3-10 parts of dispersant polyethylene wax, 5-10 parts of antioxidants and 1-3 parts of stearate. The coupling anti-oxidation special color master batch is modified by adding the coupling agents and the antioxidants. The color master batch has the advantages that the color master batch has high concentration and dispersity and has coupling, oxygen inhibition and anti-oxidation functions, and the barrier effect of the barrier bottle is further enhanced.

Description

technical field [0001] The invention relates to a coupling anti-oxidation special color master batch for barrier bottles and a preparation method thereof, belonging to the field of color master batches. Background technique [0002] Generally speaking, ordinary polyethylene (PE) plastic bottles can be used to fill water and some suspensions, but they cannot be used for the packaging of EC pesticides. For emulsifiable pesticides, ordinary polyethylene (PE) plastic bottles have pesticide penetration, and organic solvents in emulsifiable pesticides will escape through the molecular gap of the plastic bottle wall, so a barrier bottle is required. The barrier bottle is composed of three layers, the outer layer is made of high-density polyethylene material, the middle layer is made of bonding material, and the inner layer is made of synthetic polymer EVOH. High barrier, impermeability, high strength, stable performance, can prolong the storage time of solvents, generally used in ...
