Problems solved by technology

When the existing leather materials are screen-printed, solvent-based inks are mainly used. The existing solvent-based screen leather inks are quite mature in technology, but the solvents in the inks are easy to volatilize into the atmosphere, causing environmental pollution. The production of plate ink is being restricted by many laws and regulations. The development and application of green screen ink that meets environmental protection requirements will become an inevitable trend, and ink is one of the main development directions

Abstract

The invention relates to a screen printing environmental protection wash painting applied to a leather substance and belongs to the field of outdoor sports materials. The screen printing environmental protection wash painting applied to the leather substance comprises the following components in percentage by mass: 20-30 percent of soft water, 60-70 percent of modified waterborne polyurethane resin, 2-3 percent of a coalescing agent, 1-2 percent of a flatting agent, 1-2 percent of a non-ionic wetting defoamer, 0-5 percent of a pigment, 0-2 percent of a polymeric dispersant, 1-2 percent of a defoamer, 1-2 percent of a thickener and 1-5 percent of a hardening agent. All the components of the wash painting provided by the invention can be directly diluted by the soft water, the operation is easy, the usage amount of a solvent can be effectively reduced, and further the discharge of VOC is further reduced; all the components not only play specific roles thereof, but also take a synergistic effect thereamong and supplement one another, the abrasive resistance of the finished product is relatively good, a 205 g weight wrapped with Number 1200 waterproof abrasive paper in one square centimeter area is used for rubbing printing patterns on the leather substance for 250 times, and base exposing cannot be caused. When the wash painting is used for printing on the leather substance, the advantages of high gloss, excellent flatness, strong friction pull, no bleeding and the like can be achieved.

Description

Technical field [0001] The invention relates to an environmentally-friendly screen printing ink applied to leather materials, which belongs to the field of outdoor sports materials. Background technique [0002] Leather materials are mainly divided into the following categories: (1) Natural leather: processed animal fur that has been tanned, tanned or treated by other methods to resist corruption, and is soft and supple when the weather is dry; (2) ) Recycled leather: After crushing various animal waste skins and leather scraps, it is made by mixing chemical raw materials; (3) Artificial leather: Artificial leather is also called imitation leather or rubber, which is the general name of PVC and PU and other artificial materials; (4) Synthetic leather: a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. The surface is mainly polyurethane, and the base material is a non-woven fabric made of synthetic fibers s...
