Rubber cement for improving printing rubbing color fastness and dryness and preparation method thereof

Abstract

The invention discloses rubber cement for improving printing rubbing color fastness and dryness. The rubber cement comprises the following raw materials in part by weight: 50 to 80 parts of acrylate emulsion, 5 to 20 parts of biomass white solid powder, 0.5 to 1 part of dispersing agent, 5 to 10 parts of emulsifying wax solution, 0.5 to 1 part of thickener and 10 to 25 parts of purified water. The rubber cement is high in printing performance, rubbing color fastness and dryness, and overcomes the defect that a color fixing agent or a cross-linking agent is needed to be used in the traditional printing process, raw materials are readily available and moderate in cost, and the production cost of a printing coating is reduced. The invention also discloses a preparation method for the rubber cement. The method is simple, low in cost, environment-friendly and safe.

Description

technical field [0001] The invention belongs to the technical field of printing mucilage, and in particular relates to a mucilage for improving printing rubbing color fastness and dryness and a preparation method thereof. Background technique [0002] In the printing process of textile pigment printing, it is necessary to use glue and color paste together, and print them on the textile fabric through screen printing to form printing patterns of various colors. At present, the paste used in pigment printing mainly uses acrylate emulsion or polyurethane emulsion as the film-forming material, uses titanium dioxide as the main white colorant, and uses various pigment pastes as other colorants. However, due to the difference in the coloring ability of the color paste, the printed pattern is prone to color fading, fading, and bleeding, especially the performance of the acrylic emulsion, which directly affects the rubbing color fastness of the printing and seriously affects the pri...

Problems solved by technology

However, due to the difference in the coloring ability of the color paste, the printed pattern is prone to color fading, fading, and bleeding, especially the performance of the acrylic emulsion, which directly affects the rubbing color fastness of the printing and seriously affects the printing quality.

At present, in order to solve the disadvantages of poor coloring ability caused by the combination of mucilage and color paste, in the traditional process, an appropriate amount of color-fixing agent or cross-linking agent is added to improve the rubbing fastness and dryness of printing, but The addition of such additives to the mucilage will gradually thicken the mucilage, making printing difficult; moreover, the production conditions of such auxiliaries are very polluting to the environment, the production conditions are difficult, and the price is high, which greatly increases the cost of printing paint production and risk
