Problems solved by technology

[0004] Since the umbrella surface substrate is a waterproof coating, when the water-based screen printing ink prints the pattern, there are problems such as uniformity of the pattern ink layer on the umbrella surface, and the leveling of the water-based ink printed on the screen plate is different from the leveling of the umbrella surface ink. A pair of contradictions, therefore, the existing water-based ink is difficult to color on the base material of the umbrella surface; when the machine is printed in batches, it is difficult to quickly dry the water-based ink pattern of each set of colors and cause anti-sticking phenomenon; After printing, there is a problem that the pattern adhesion fastness is not up to standard

Embodiment Construction

[0036] A kind of umbrella water-based ink of the present invention, selects water-based polyurethane emulsion (54-58.5) g, titanium dioxide (20-30) g, color paste (5-12) g, blocked isocyanate (5) g according to the weight ratio ~8) g, dispersant (0.5-0.7) g, defoamer (0.5-0.7) g, other additives (0.5-0.7) g to make water-based ink. Use the DOE method to select the optimal formula of HBS water-based ink suitable for polyester umbrella screen printing. The level first sets the maximum and minimum values ​​according to the water-based ink, and the intermediate parameters are designed according to the arithmetic sequence. This test design has five factors and four levels. Choose L 16 (4 5 ) orthogonal test, see Table 1, Table 2 and Table 3 for the specific implementation of the test. The adjuvants in the table include equal amounts of dispersant, defoamer and other adjuvants.

Abstract

The invention discloses an umbrella-dedicated water-based ink for terylene plain fabrics and a coating method thereof. the water-based ink comprises: by weight, 54-58.5 parts of a waterborne polyurethane emulsion, 20-30 parts of titanium dioxide and / or 5-12 parts of a color paste, 5-8 parts of blocked isocyanate, 0.5-0.7 part of a dispersant, 0.5-0.7 part of an antifoaming agent, and 0.5-0.7 part of other auxiliary agents. The product provided by the invention has good levelability and strong curling resistance. An umbrella surface finished product will not be adhered back after laminated and the coating will not be damaged. Scrapping is little. Pattern color is more stable. The product is safe, nontoxic, harmless, non-combustible and nonexplosible. Volatile gas is barely generated. Cost is low. The product has remarkable economic benefit.

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...
