Water-based nano high-coverage 3D printing coating and preparation method thereof

Abstract

The invention provides a water-based nano high-coverage 3D printing coating which is prepared from water-based polyurethane resin, water-based nanoscale color paste, ionized water and propylene glycol at the mass ratio of (75-90):(6-10):(9-11):(1-3), wherein the solid content of the water-based polyurethane resin is 50-60%; and the fineness of the water-based nanoscale color paste is 85-100nm. The preparation method of the water-based nano high-coverage 3D printing coating comprises the main steps of preparing the water-based polyurethane resin and the water-based nanoscale color paste separately, and then fully mixing the water-based polyurethane resin, the water-based nanoscale color paste, the ionized water and the propylene glycol at the mass ratio; and adding a polyurethane thickening agent for viscosity control to prepare the water-based nano high-coverage 3D printing coating. The water-based nano high-coverage 3D printing coating has the characteristics of high coverage rate, high elasticity and high third dimension, can adapt to the diversity of printing materials, and is relatively low in production cost and suitable for large-scale industrial production, therefore, the water-based nano high-coverage 3D printing coating has potential market values and wide application prospects.

Description

technical field

[0001] The invention belongs to the field of polymer materials, and relates to a 3D printing coating, in particular to a water-based nano high covering 3D printing coating and a preparation method thereof. Background technique

[0002] The environmentally friendly digital printing process has the advantages of energy saving and emission reduction, bright colors, high precision and good hand feeling. Its advanced production principles and technical measures have brought new concepts and unprecedented opportunities to the textile printing industry. my country's digital printing started late, and advanced digital printing machines are imported from abroad, and the corresponding digital printing ink consumables have always relied on foreign imports due to their high quality requirements.

[0003] For digital printing ink, a certain amount of wastewater will be generated in the process of pre-treatment sizing and post-treatment washing, and all current digital pri...
