Abstract

The invention discloses a weak solvent ink absorbing coating, and the coating is prepared from the following raw materials in parts by weight: 100-130 parts of modified sol solution, 5-8 parts of triethanolamine, 6-7 parts of boric acid, 0.3-1 part of p-toluene sulfonic acid, 1-2 parts of calcium palmitate, 1-2 parts of octylphenol polyoxyethylene ether, 7-11 parts of oil soluble phenolic resin and 15-20 parts of castor oil. The coating disclosed by the invention is good in environmental protection property, free of toxic and harmful volatile substances, good in ink fixity and excellent in comprehensive performance.

Description

technical field [0001] The invention belongs to the field of coating materials, in particular to a weak solvent ink absorbing coating and a preparation method thereof. Background technique [0002] Eco-solvent ink absorbing coating is digital inkjet ink that uses eco-solvent ink to print directly on substrates such as glass, plastic, ceramics, and hardware. Since the solvent in the ink cannot be evaporated as soon as possible, the image is not clear. If these First coat a layer of coating liquid on the substrate and then print. Due to the ink-absorbing and color-fixing effect of the coating, the printing effect is the same as or better than that of paper printing; [0003] The current weak solvent ink absorption coating has poor film-forming performance, weak fixing effect, and weak hydrophobicity and surface resistance after film formation. Contents of the invention [0004] The object of the present invention is to provide a kind of weak solvent ink absorbing coating an...
