Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch particles, in particular to low-volatile yellow masterbatch particles. Background Art

[0002] A masterbatch is a mixture of resin and a large amount of pigment or dye to create a highly concentrated color. Masterbatch, also known as color seed, is a type of aggregate made by uniformly loading an unusual amount of pigment or dye onto a resin.

[0003] Currently, the titanium dioxide content of PET masterbatches used in photovoltaic backsheet films is typically 55%-60%, and due to reflectivity requirements, a fluorescent brightener must be added. Manufacturers typically add 10%-20% masterbatch, depending on the thickness of the BOPET film (25µm-50µm). To achieve the required dispersion of the masterbatch, dispersants such as oxidized wax and diffusion oil are added. Furthermore, commercially available fluorescent brighteners rarely meet high purity requirements and inevitably contain small molecules.

[0004] Because the masterbatch addition amount is high and it contains small molecular compounds, when manufacturers produce BOPET film for a long time, the small molecular compounds will volatilize and cause obvious "smoke", seriously affecting the workshop production environment and causing cross contamination. They will also accumulate on the sensing equipment and cause the sensing equipment to fail. Therefore, we need to propose a low-volatile yellow masterbatch particle. Utility Model Content
