Chlorinated paraffin-containing wax emulsion for leather, and preparation method thereof

Abstract

The invention discloses a chlorinated paraffin-containing wax emulsion for leather, and belongs to the technical field of wax emulsion preparation. The wax emulsion is prepared from, by weight, 20-25 parts of chlorinated paraffin, 1-4 parts of microcrystalline wax, 0.9-1.6 parts of quaternized myristamidosiloxane, 5-8 parts of film forming resin, 2-5 parts of phytosterin isostearate, 1-2 parts of ethylene glycol butyl ether, 0.5-1 part of N-methylfattyamido taurate, 1-2 parts of polyoxyethylene fatty acid amide, 0.1-0.3 parts of nylon-6, 0.5-0.8 parts of stearyl alcohol polyoxyethylene ether, 1-3 parts of acacia gum and 90-200 parts of water. The invention also provides a preparation method of the wax emulsion. The wax emulsion improves the hand feeling of a leather finishing agent to make leather products have good hand feeling. Compared with products of the same kind, the wax emulsion disclosed in the invention has the advantages of excellent acid, alkali and hard water resistance, good stability, no layering after being diluted with water according to an arbitrary ratio, no demulsification or agglomeration in the storage period, and long shelf life.

Description

technical field [0001] The invention relates to a preparation method of a wax emulsion, in particular to a leather wax emulsion containing chlorinated paraffin and a preparation method thereof. Background technique [0002] Wax emulsion is mainly used as a leather finishing auxiliary in the leather industry, used for bottom, middle and top coating, and has good performance. Waxes have common characteristics of water repellency and lubricity, but also have characteristics such as oiliness, stickiness, brittleness, toughness, melting and gloss, which are very different from each other. In practice, it is impossible for a wax to have all the properties required for a particular application. Therefore, when selecting the raw materials of the wax emulsion for leather finishing, it is necessary to comprehensively consider the performance of the wax to improve the finishing performance of the leather finishing. Wax emulsion has been more and more favored by researchers and users ...
