Umbrella water-based ink for satin fabrics and coating method of water-based ink

Abstract

The invention discloses umbrella water-based ink for satin fabrics and a coating method of the water-based ink. The water-based ink comprises, in parts by weight, 40-50 parts of a waterborne polyurethane emulsion, 20-25 parts of a water-based self-crosslinking acrylic emulsion, 10-15 parts of a water-based styrene-acrylic emulsion, 20-30 parts of titanium dioxide and / or 10-20 parts of color paste and 5-10 parts of an assistant. The water-based ink has the advantages that products are good in leveling property and high in crimp resistance, reverse sticking and the damage to coatings can be avoided after finished umbrella covers are overlaid, scrapping is less, and pattern colors are more stable; and the water-based ink is safe, non-toxic, innocuous, non-ignitable, non-explosive, almost free of volatile gases and low in cost, has significant economic benefits and the like.

Description

technical field [0001] The invention relates to the field of umbrella making, in particular to the field of umbrella surface processing, in particular to an umbrella water-based ink and a coating method thereof. Background technique [0002] The umbrella industry is a traditional industry in my country and one of the labor-intensive industries. Traditional equipment, traditional technology, low barriers to industry entry, low technical content, conventional umbrella surface pattern decoration using screen printing, however, the use of solvent-based ink printing in the screen printing process, so it has not fundamentally Improve the quality level of silk screen products and reduce environmental pollution. [0003] At present, the umbrella industry still generally uses solvent-based inks for printing, and a large amount of volatile gases will be produced during the screen printing process, which contains toluene, xylene and other gases that will have a certain impact on human...

AI Technical Summary

Problems solved by technology

[0004] Since the umbrella surface substrate is a waterproof coating, there is a problem of leveling of the umbrella surface when the water-based screen printing ink prints the pattern, and the leveling of the water-based ink printed on the screen plate and the leveling of the umbrella surface pattern are a pair of contradictions Therefore, the existing water-based ink is difficult to color on the base material of the umbrella surface; when printing in batches, it is difficult to quickly dry the water-based ink pattern of each set of colors and cause anti-sticking phenomenon; after the water-based ink is printed on different umbrella surface coatings, there is The problem that the pattern adhesion fastness is not up to standard
