Abstract

The invention discloses a leather fogging treating agent which is prepared from the following raw materials in parts by weight: 50-60 parts of water-based polyurethane resin, 20-35 parts of deionized water, 1-5 parts of emulsified silicone oil, 0.5-2 parts of organic silicon leveling agent, 1-7 parts of nonionic water-based polyurethane thickener, 1-5 parts of superfine nano scrap rubber micropowder, 1-4 parts of kaolin and 0.5-3 parts of silane coupling agent. The superfine nano scrap rubber micropowder, which is coated by the coupling agent and added into the treating agent, can enhance the binding force between the resin and rubber micropowder, so that the bonding strength between the treating agent and leather surface is enhanced, and the coating can not easily shed. The leather surface can display the stereoscopic fogging effect, and thus, the leather fogging treating agent has better surface decoration property. The preparation process adopts an ultrasonic treatment mode, so that the obtained emulsion is more uniform, and the molecules are bonded more firmly, thereby improving the quality of the treating agent and prolonging the shelf life and use effect.

Description

technical field [0001] The invention relates to a surface treatment agent, in particular to a leather fog surface treatment agent, and belongs to the technical field of leather processing preparations. Background technique [0002] With the development of technology, leather products have achieved diversified production and enriched people's lives. With the development of technology, people have gradually studied the treatment methods of matte surface, bright surface, aging, color enhancement and embossing on the leather surface, so as to obtain leather products with various surface effects, which enrich people's choices. The matte treatment of leather is a common surface treatment method, which is mainly to form a coating with a matte effect on the leather surface by wiping or spraying a matte treatment agent on the pretreated leather surface. [0003] CN 103255628A discloses a matte wetness treatment agent for synthetic leather and a preparation method thereof. The matte ...
