Abstract

The invention relates to the field of pigments, and discloses a method for preparing a UV-resistant polymer-coated nano-alumina pigment. The invention first prepares AlOOH, and then modifies the surface of AlOOH by 3-aminopropyltriethoxysilane to reduce the Agglomeration of AlOOH during ball milling, preparation of nanometer γ‑Al by high energy ball milling 2 o 3 . Then using nanometer γ-Al 2 o 3 The amino group introduced on the surface reacts with the dichloro-s-triazine type reactive dye, so that the dye molecule is grafted on the nanometer γ‑Al 2 o 3 superior. Finally, a layer of copolymer is coated on the surface of the nano pigment particles to prepare the pigment. Due to the existence of nano-alumina, the anti-ultraviolet performance of the pigment is greatly improved; moreover, the copolymer coating can tightly cover the dye molecules and alumina, and can be melted tightly with the fabric during the heating and drying process of the fabric. Tightly combined, the pigment particles will not fall off after rubbing, so that the pigment has high color fastness.

Description

technical field [0001] The invention relates to the field of pigments, in particular to a method for preparing an ultraviolet-resistant polymer-coated nano-alumina pigment. Background technique [0002] Digital inkjet printing technology is the latest printing technology that appeared internationally in the 1990s. Compared with traditional printing technology, inkjet printing can greatly reduce the cost of etching patterns, and has high printing accuracy, which is the most effective method for fabric printing. The ink used in inkjet printing is mainly divided into pigment ink and dye ink. In recent years, pigment ink is the current inkjet printing ink because of its versatility for various fabrics, simple printing process, less pollution, and significant energy saving and emission reduction advantages. main direction of development. However, due to the erosion of the external environment, especially the ultraviolet radiation in the sun, most inkjet printed fabrics will fad...
