Description
Technical field
The present invention relates to the preparation method of a kind of wax emulsion, particularly to a kind of leather finish cationic wax emulsion and
Its preparation method.
Background technology
Wax emulsion in leather industry mainly as leather finish auxiliary agent, for the end, in, top coat, there is preferable performance.
Wax had both had the general character of water proofing property and lubricity, in terms of having again such as oiliness, viscosity, fragility, toughness, fusibleness and gloss
Characteristic, is very different to each other.In actual applications, a kind of wax can not have the institute met required for a certain special-purpose
There is character.Therefore, when selecting the raw material of leather finish wax emulsion, the serviceability of wax to be considered, improves leather and is coated with
The Spraying technique of decorations.According to the type of emulsifying agent used, wax emulsion is often divided into anionic, nonionic, cationic and two
Property ion-type four class.Owing to generally showing elecrtonegativity without the skin base surface covered with paint, lacquer, colour wash, etc., can be relatively covering with paint, lacquer, colour wash, etc. processing cationic wax emulsion
Soon combined with leather surface and form thin film, it is effectively prevented coating material too much permeation effects leather hand feeling, makes skin
Leather embodies the performances such as good, the elegant softness of feel of coat fastness.Based on above advantage, cationic wax emulsion is subject to the most more and more
To researcher and the favor of user, abroad to its research and development the most for many years, and define numerous in variety, excellent performance
Tandem product.
