Technical Field
The invention belongs to the field of color master batch manufacturing, and particularly relates to an ultraviolet-resistant polyethylene color master batch and a preparation method thereof.
Background
Color concentrates are high-concentration pigment mixtures prepared by mixing a carrier resin with a large amount of pigment, which contain an excess amount of pigment. In the industrial production process, a small amount of color master batch is mixed with uncolored resin to prepare a colored resin product meeting the design requirement.
Polyethylene (PE) is a thermoplastic resin that is widely used, has excellent processability and low water absorption, and can maintain good mechanical properties even in a low-temperature environment. However, the polyethylene material has poor aging resistance, and is easy to age in a use environment with strong ultraviolet rays, so that the mechanical property of the polyethylene material is greatly reduced, and the service life of a product is further influenced. If the unmodified polyethylene material is prepared into color master batch and added into a product with higher ageing resistance requirement, the environmental stress cracking resistance of the final product is greatly reduced and even unqualified. Therefore, the polyethylene material needs to be modified to prepare a polyethylene color master batch with excellent ultraviolet resistance and aging resistance to adapt to different required use conditions.
