Embodiment 1

[0016] A wax emulsion for painting, the wax content in the wax emulsion is 7.5% (percentage by weight); in parts by weight, the wax emulsion is prepared from 0.75 parts of palm wax, 0.15 parts of Pingpingjia, and 9.25 parts of boiling water (100 ° C);

[0017] The preparation method is: add 0.75 parts of palm wax into the container and heat it to 60°C to melt it. When the wax is heated to smoke, add 0.15 parts of Pingping plus emulsifier, stop heating after the emulsifier is dissolved, drop into boiling water, and then Heating to boiling and filtering to obtain a wax emulsion, the filtering method is an existing conventional filtering method.

[0018] Poorly emulsified wax does not disperse in cold water and sinks to the bottom of the water. On the contrary, it disperses in flocculent form and emulsifies well.

Embodiment 2

[0020] A wax emulsion for painting, the wax content in the wax emulsion is 10% (percentage by weight); in parts by weight, the wax emulsion is prepared from 1 part of paraffin wax, 0.2 part of flat wax, and 9 parts of boiling water (100 ° C);

[0021] The preparation method is: add 1 part of paraffin wax into the container and heat it to 63°C to melt it. When the wax is heated to smoke, add 0.2 part of Pingping plus emulsifier, stop heating after the emulsifier dissolves, drop into boiling water, and then heat To boiling, the wax emulsion was obtained by filtration.

Embodiment 3

[0023] A wax emulsion for painting, the wax content in the wax emulsion is 7.5% (percentage by weight); by weight, the wax emulsion is composed of 0.2 part of paraffin wax, 0.55 part of palm wax, 0.25 part of Pingpingjia, 9.25 parts of boiling water (100 ℃) formulated;

[0024] The preparation method is: add 0.2 parts of paraffin wax and 0.55 parts of palm wax into the container and heat it to 57°C to melt it. When the wax is heated to smoke, add 0.25 parts of Pingping plus emulsifier, stop heating after the emulsifier is dissolved, and drop in 9. After 25 parts of boiling water, heat to boiling and filter to obtain wax emulsion.

Abstract

The invention discloses a wax finishing emulsion and a preparation method thereof, which belong to the technical field of leather processing. The emulsion contains 7.5-10% of wax, and the emulsion is prepared by comprising the following components in parts by weight: 0.75-1 part of wax, 0.15-0.25 parts of an emulsifier, 9-9.25 parts of boiling water. The preparation method is characterized in that wax is added in a container, heated until the wax is molten, when wax is heated to generate smoke, the emulsifier is added, heating is stop after the emulsifier is dissolved, boiling water is dropped, and then the product is heat to a boiling state, and the material is filtered to obtain the emulsion. The emulsion is dispersed in a flocculent state, has the advantages of good emulsification, less usage of the raw materials, low cost, and simple preparation method, and is adapted to wide usage.

Description

technical field [0001] The invention belongs to the technical field of leather processing, and relates to a finishing wax emulsion and a preparation method thereof. Background technique [0002] Leather finishing agent is a general term for a class of leather auxiliaries used to protect and beautify leather on the surface of leather. The surface of the leather treated with the finishing agent can form a film protective layer, which can cover the defects of the leather and improve the grade of the leather, endowing the synthetic leather with a beautiful appearance, a comfortable feel and good mechanical and physical properties. [0003] In the tanning industry, commonly used leather finishes include acrylate finishes, casein finishes, nitrocellulose finishes and water-based polyurethane finishes. Among them, the water-based polyurethane finishing agent uses water as the solvent, and the product has no volatile organic solvents. It has the characteristics of non-toxicity, goo...
