Cationic paraffin emulsion as well as preparation method and application thereof

Abstract

The invention discloses a cationic paraffin emulsion as well as a preparation method and an application thereof and belongs to the technical field of paraffin emulsion processing. The cationic paraffin emulsion is technically characterized by being prepared from components in percentage by weight as follows: 42%-43.5% of paraffin, 1.3%-2.15% of fatty amine polyoxyethylene ether, 0.01%-0.22% of glacial acetic acid and 54.5%-55.0% of water. The preparation method of the cationic paraffin emulsion comprises operation steps as follows: step 1, water, paraffin, fatty amine polyoxyethylene ether andglacial acetic acid are added to a reaction kettle, and the reaction kettle is sealed; step 2, the reaction kettle is heated to 80-105 DEG C, a thermal insulation reaction is performed for 1-5 h until the paraffin and the fatty amine polyoxyethylene ether in the reaction kettle are fully melt; step 3, stirring is started and the temperature in the reaction kettle is controlled at 70-95 DEG C; step 4, homogenization and discharging are performed, a product is cooled to the room temperature, and the cationic paraffin emulsion can be obtained. According to the cationic paraffin emulsion, the total content of fatty amine polyoxyethylene ether is lower; the paraffin is waterproof, but an emulsifier is not waterproof, so that the waterproof property and the lubrication performance 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...

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
