Embodiment Construction

[0018] (1) Take the following raw materials according to the process ratio:

[0019] Beeswax, Sichuan wax, Pingpingjia O-20, Siben-80, distilled water

[0020] (2) Put Siben-80 and Pingjia O-20 into a container, heat and melt, stir evenly, and cool down for later use;

[0021] (3) Put the mixture obtained in (2), beeswax, and Sichuan wax into an emulsifier, heat and melt, and stir evenly; the temperature of the heating medium is 120-150°C, and the stirring time is not less than 5 minutes;

[0022] (4) Add distilled water dropwise to the mixture obtained in (3) under stirring; the initial water addition speed is 0.5Kg / min, and the stirring speed is 300rpm; The speed is 500rpm; when the water is continuously added until the material becomes thinner, the water adding speed is adjusted to 6Kg / min, and the stirring speed is 800rpm until all the water is added.

[0023] (5) Stop stirring after adding the water;

[0024] (6) Filtrating the material obtained in (5) to obtain a fini...

Abstract

The invention discloses a preparation method of a wax emulsion as a leather finishing addictive, comprising the following preparation steps of: adding span-80 and perogol O-20 in a container, heating, melting, uniformly stirring and adding in an emulsor; adding bee wax and cera flava in the emulsor, heating, melting and uniformly stirring; dropping distilled water by stirring; stopping stirring after finishing adding water; and filtering the obtained materials to obtain a finished product. The wax emulsion as the leather finishing addictive can be applied to slurry for decorating the bottom layer, the intermediate layer and the top layer of leather, can greatly improve the hand feeling of the finished leather, has various functions of preventing sticking, smoothening, resisting water, softening, filling, glazing and the like and can also improve the dry and wet wiping resistance of the finished leather. The wax emulsion is a high-grade finishing addictive for producing pig, cow and sheep light-color leather or white leather.

Description

technical field [0001] The invention relates to a preparation method of leather finishing auxiliary wax emulsion. Background technique [0002] Leather wax emulsion is an important auxiliary material in the leather finishing process. At present, many domestic tanneries still use natural montan wax and soap flakes for preparation. Due to the black color and unstable system, it can no longer meet the requirements of high-grade leather production. Currently commercially available commercial waxes mainly include paraffin wax, ozokerite wax, insect wax, beeswax, palm wax, montan wax, etc. From the chemical structure analysis, these waxes can be roughly divided into three types, one is a compound mainly containing fatty acid ester structure, the other is pure hydrocarbons, and the other is alkanes containing both hydrocarbons and Fatty acids or mixtures of fatty acids and fatty alcohols. Above-mentioned three kinds of waxes have single performance, all can't satisfy the tannin...
