Problems solved by technology

[0004] Existing technologies for preparing paraffin emulsions generally rely on emulsifiers and co-emulsifiers. Most emulsifiers have low emulsification efficiency and poor emulsion stability. Co-emulsifiers (cetyl alcohol, Bridger 52, betaine) must be used to increase the dispersion of the emulsion stability
The addition of co-emulsifiers increases the proportion of small molecular compounds in the paraffin wax emulsion, which cannot avoid problems such as poor stability, migration and substrate contamination caused by small molecular compounds
Moreover, a variety of emulsifiers must be used to prepare a stable paraffin emulsion, which increases the complexity of the composition of the paraffin emulsion

Description

Technical field [0001] The invention belongs to the technical field of leather coating wax agents, and particularly relates to an environmentally friendly stable leather coating wax. 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 meet the needs of leather products of different colors. However, the traditional dyed leather often presents the defect of poor hand feeling. Moreover, due to the addition of toluene or xylene in the traditional batik, a large amount of long-term use will also cause serious pollution to the environment. Existing leather auxiliaries such as oil lubricants, smoothing agents, hand-feeling agents, cleaning agents and brighteners are mostly made of imported raw materials such as carnauba wax, which are expensive and have single functions. [0003] Paraffin wax emulsion is a uniform dispersion system formed by mixin...
