Problems solved by technology

Another example is that the Chinese invention patent application with the notification number CN106188572A discloses a high-solid paraffin emulsion and a preparation method thereof. In the above two inventions, an aqueous solution of aluminum sulfate is introduced, which can be used in wood, leather and metal products. Used as an additive, which has a certain limit on the scope of use of the emulsified paraffin wax
[0009] The emulsifier content in the emulsion obtained by the above two methods is relatively large, which will affect the water resistance of the paraffin wax, so a new technical solution needs to be proposed to solve the above problems

[0049] Embodiment 2: a cationic paraffin emulsion, comprising 25.6Kg of pure water, 20Kg of No. 75 microcrystalline paraffin, 1Kg of tallow amine-2EO, 0.1Kg of 99% glacial acetic acid by weight.

[0050] Its preparation method is: with the pure water of 25.6Kg, No. 75 microcrystalline paraffin of 20Kg, the tallow amine-2EO of 1Kg (promptly containing the tallow amine polyoxyethylene ether of two ethylene oxide EOs), 0.1Kg weight percent is Add 99% glacial acetic acid into the pressure emulsification kettle, and seal the pressure emulsification kettle; then directly heat to 102.5±2.5°C, keep warm for 4 hours until the No. 75 microcrystalline paraffin and tallow amine-2EO in the pressure emulsification kettle All melted, followed by temperature-controlled stirring at a stirring speed of 60r / min. After stirring for 12 minutes, the temperature in the pressure emulsification tank reached 95°C. At this time, under a homogenizing pressure of 35MPa, the material was homogenized and dis...

Embodiment 3

[0051] Embodiment 3: a cationic paraffin emulsion, including 25.6Kg of tap water, 20Kg of No. 75 medical white petrolatum, 0.6Kg of dodecylamine-5EO, and 0.03Kg of 99% glacial acetic acid by weight.

[0052] The preparation method is as follows: 25.6Kg of tap water, 20Kg of No. 75 medical white vaseline, 0.6Kg of dodecylamine-5EO (that is, dodecylamine polyoxyethylene ether containing five ethylene oxide EOs), 0.03Kg of weight Add glacial acetic acid with a percentage of 99% into the pressure emulsification kettle, and seal the pressure emulsification kettle; then directly heat it to 75±5°C and keep it warm for 3.5 hours until all the dodecylamine-5EO in the pressure emulsification kettle melts , and then carry out temperature-controlled stirring at a stirring speed of 70r / min. After stirring for 13 minutes, the temperature in the pressure emulsification tank reaches 70°C. At this time, under a homogenizing pressure of 35MPa, the material is homogeneously discharged through a h...

Abstract

The invention discloses a cationic paraffin emulsion and its preparation method and use. It belongs to the technical field of paraffin emulsion processing. Its technical points are: a cationic paraffin emulsion, including the following components in terms of weight percentage: paraffin 42-43.5%; Fatty amine polyoxyethylene ether 1.3-2.15%; glacial acetic acid 0.01-0.22%; water 54.5-55.0%. The preparation method includes the following steps: Step 1: Feed water, paraffin, fatty amine polyoxyethylene ether, and glacial acetic acid into the reaction kettle, and seal it; Step 2: Heat the reaction kettle to 80-105°C, and keep the reaction 1-5 hours until the paraffin and fatty amine polyoxyethylene ether in the reaction kettle are completely melted; Step 3: Start stirring and control the temperature in the reaction kettle at 70-95°C; Step 4: Discharge homogeneously and cool to room temperature to obtain Cationic paraffin emulsion. The cationic paraffin emulsion of the present invention has a low total content of fatty amine polyoxyethylene ether. Since paraffin is waterproof but the emulsifier is not waterproof, the waterproofness and lubricating properties of paraffin are guaranteed to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of paraffin emulsion processing, more specifically, it relates to a cationic paraffin emulsion and its preparation method and application. Background technique [0002] Paraffin wax emulsion is a waxy and water-containing homogeneous fluid made by physical modification of various waxes including petroleum wax; it is made of paraffin wax and several emulsifiers of different types and performances and appropriate regulators through emulsification reactions. A stable emulsion of solid-oil-water multiphase dispersion system. [0003] It is understood that paraffin is the most widely used wax. In emulsion, paraffin is often used as waterproofing agent, lubricant and release agent. Cationic paraffin emulsions are often used in cationic systems, which are suitable for areas with negative surface charges, such as fabrics, paper fibers, etc. [0004] The current technologies can be roughly divided into two categor...
