Abstract

The invention discloses a preparation method of digital printing ink based on boron nitride nanosheet modification. The method comprises the following steps: firstly, preparing boron nitride nanosheets by a solvent stripping method, then performing surface activation on the boron nitride nanosheets by using a hydrochloric acid solution and a hydrogen peroxide solution to obtain activated boron nitride nanosheets, and finally modifying by using a silane coupling agent to obtain modified boron nitride nanosheets; uniformly mixing an aqueous vegetable dye and deionized water by stirring, then adding a viscosity regulator, a bactericide and a pH regulator, uniformly mixing by stirring, continuing adding the modified boron nitride nanosheets, finally adding a wetting agent, mixing by stirring,then heating to 60-70 DEG C, mixing by stirring for 1-2h, then cooling to a room temperature, continuing stirring for 1-2h, and filtering by using a polypropylene membrane with the thickness of 0.25-1micron to obtain the digital printing ink. By the method, the operation is simple, the obtained digital printing ink is good in stability, excellent in high temperature resistance, non-toxic and environment-friendly.

Description

Technical field: [0001] The invention relates to the textile field, in particular to a method for preparing ink for digital printing based on the modification of boron nitride nanosheets. Background technique: [0002] The printing and dyeing industry is an important link in the textile industry chain and a key process to increase the added value of textiles and clothing. After long-term development, the production and processing capacity of my country's printing and dyeing industry has ranked first in the world, but there are still problems such as insufficient innovation ability, low added value of products, and inadequate environmental protection. The printing and dyeing industry urgently needs industrial transformation and technological upgrading, and digital printing has become a “outlet” for the development of the industry. [0003] Textile digital printing inks are mainly divided into four types: dispersion, reactive, acid and paint inks. In the current market, disperse in...
