Embodiment 1

[0042] The composition of raw materials is as follows:

[0043] A component:

[0044] Paraffin 100kg

[0045] B component:

[0046]

[0047] C component:

[0048] Lye 7kg.

[0049] The preparation method is as follows:

[0050] (1) Weigh 100kg of component A, put it in a reaction kettle, heat and melt it for later use.

[0051] (2) Weigh 6kg of component B, add 30kg of water, control the temperature at 80°C, stir evenly, and the solution becomes viscous and transparent.

[0052] (3) Start the agitator (rotating at 100 rpm), and after the temperature in the kettle rises to 90°C, slowly add component B into the kettle and continue the reaction for 15 minutes.

[0053] (4) Slowly add 7kg of component C lye into the kettle in four times, and the emulsion changes from yellowish transparent → translucent → milky white and sticky → milky white and slightly blue, and the viscosity tends to the viscosity of the outer phase water. The water continues to stir, fully dilutes and...

Abstract

The invention belongs to the technical field of chemical synthesis and particularly relates to emulsified paraffin and a preparation method thereof. The emulsified paraffin is prepared from a component A, a component B and a component C, wherein the component A is prepared from paraffin, the component B is prepared from stearic acid, glycerin monostearate, fatty alcohol-polyoxyethylene ether, high-carbon alcohol, hydroxymethyl cellulose and water-soluble starch, and the component C is prepared from alkali liquor. The emulsified paraffin is simple in process and low in energy consumption, the dosage of required emulsifiers is small and is only 6%-7% of the paraffin amount, and the rotating speed of a stirrer is greatly decreased; and a product is placed at a shade place in a sealed mode, and thus the product can be stored for one year without layering, demulsifying and caking.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to an emulsified paraffin wax and a preparation method thereof. Background technique [0002] Emulsified paraffin is a kind of oil-in-water uniform emulsion formed by uniformly dispersing paraffin in water under the action of external mechanical force by virtue of the hydrophilic and lipophilic properties of emulsifiers. It can be diluted with water and has the advantages of safety and environmental protection. It is a widely used chemical product. However, traditional emulsifiers are used in a large amount and the operating conditions are harsh. The emulsified paraffin wax formed is not suitable for storage, has a pungent taste, and is not resistant to hard water, acid and alkali. [0003] Patent CN1570038A discloses a paraffin emulsifier, which is composed of the following components in a series of weight ratios: 20-30 parts of lauryl alcohol, 20-30 parts o...
