Abstract

The invention discloses an aqueous environment-friendly leather surface coating hand feeling smoothing oil solution which comprises the following components in portions by weight: 16-20 portions of epoxidized soybean oil, 50-58 portions of edible vegetable oil, 100-115 portions of oleic acid, 30-50 portions of peregal, 10-15 portions of triethanolamine and 300-450 portions of de-ionized water. After the surface of animal leather or man-made leather is processed by utilizing the aqueous environment-friendly leather surface coating hand feeling smoothing oil solution, the hand feeling can be obviously enhanced, thereby ensuring a smooth and natural touch. Besides, the aqueous environment-friendly leather surface coating hand feeling smoothing oil solution contains no benzene compounds, is environment-friendly in use, and has favorable application prospects and economic value.

Description

technical field [0001] The invention belongs to the technical field of hand feel wax additives for leather finishing, and in particular relates to a water-based, environmentally friendly leather surface finishing feel smooth oil agent and a preparation process thereof. Background technique [0002] Leather dyeing is a very important process in the leather processing process. Almost all tanned leather needs to go through the process of leather dyeing, so as to realize the demand for leather products of different colors. However, traditional dyed leather often presents the defect of poor hand feeling. And owing to be added with toluene or xylene in the traditional batik agent, a large amount of long-term use also will cause serious pollution to environment. Contents of the invention [0003] One of the objectives of the present invention is to provide a water-based environmentally friendly leather surface finishing hand feel smooth oil that can enhance the feel on the surfa...
