Problems solved by technology

However, the traditional dyed leather often has the defect of poor hand feeling.
Moreover, the leather processed by the traditional process has relatively strong optical reflection, especially for genuine leather goods, it is difficult to meet the needs of high-end products
Moreover, due to the addition of toluene or xylene in the traditional batik agent, a large number of long-term use will also cause serious pollution to the environment.

Abstract

The invention discloses an aqueous environmentally-friendly leather finishing and delustering handfeel wax assistant, which comprises the following components in part by weight: 80 to 110 parts of polyethylene wax, 90 to 110 parts of chlorinated paraffin, 100 to 115 parts of stearic acid, 85 to 110 parts of peregal, 90 to 105 parts of span, 8 to 15 parts of nonfat dry milk, 130 to 160 parts of silicon dioxide delustering powder and 400 to 600 parts of deionized water. When the aqueous environmentally-friendly leather finishing and delustering handfeel wax assistant of the invention is used totreat the surface of animal leather and artificial leather, the handfeel is improved so obviously that the leather touches soft, smooth and natural. And the leather treated by the finishing and delustering handfeel wax assistant overcomes the drawback of over-hard light. And the aqueous environmentally-friendly leather finishing and delustering handfeel wax assistant 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 additives for leather finishing, and in particular relates to a water-based environmental-friendly leather finishing matting touch wax additive 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. Moreover, the leather processed by the traditional process has relatively strong optical reflection, especially for genuine leather goods, it is difficult to meet the needs of high-end products. 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]...
