Abstract

The invention discloses an aqueous environmentally-friendly leather finishing handfeel wax agent, which comprises the following components in part by weight: 8 to 12 parts of chlorinated paraffin, 10 to 15 parts of liquid paraffin, 3 to 5 parts of span, 8 to 12 parts of, 10 to 14 parts of triethanolamine, 12 to 16 parts of sodium dodecyl benzene sulfonate and 180 to 200 parts of deionized water. When the handfeel wax agent of the invention is used to treat the surface of animal leather or artificial leather, the handfeel is improved so obviously that the leather touches soft, smooth and natural. And the handfeel wax agent of the invention does not contain benzene compounds and therefore is very environmentally-friendly in use and has a promising application prospect and high economic value.

Description

technical field [0001] The invention belongs to the technical field of touch wax for leather finishing, and in particular relates to a water-based and environment-friendly touch wax for leather finishing 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 environment-friendly hand feel wax that can enhance the feel on the surface of animal leather or artificial leather, so as to solve the defec...
