Production process of paraffin emulsion with high solid content

Abstract

The invention relates to the technical field of paraffin emulsions, especially to a production process of paraffin emulsion with high solid content. The production process comprises the following steps: 1) preparing industrial-grade refined paraffin, deionized water, a lipophilic emulsifier, a hydrophilic emulsifier and other raw materials, and then preparing a high-speed dispersion machine, a constant-temperature water bath pan, a centrifugal machine and other equipment; and 2) adding 7% of the lipophilic emulsifier into the paraffin. The production process has the advantages that the paraffin is emulsified by adopting two characteristic emulsifying agents, i.e., sorbitan fatty acid ester and octadecanol polyoxyethylene ether, and the whole emulsification process is conducted at a constant-temperature condition, so the problem that an interface film generated by emulsification of a traditional single emulsifier is not compact and low in mechanical strength is solved, the solid contentis improved, the paraffin emulsion is more convenient to transport and use, and transportation cost is saved; and defective products can be prevented from being generated by additionally arranging the centrifugal machine for detection, so the production quality of the paraffin emulsion is improved.

Description

technical field [0001] The invention relates to the technical field of paraffin wax emulsion, in particular to a production process of high solid content paraffin wax emulsion. Background technique [0002] Paraffin wax emulsion is a waxy and water-containing homogeneous fluid made by physical modification of various waxes including petroleum wax. The stable emulsion of the solid-oil-water multiphase dispersion system is generally selected according to the type of paraffin and emulsifier required. With the introduction and implementation of the new concept of "green chemistry", the development and utilization of paraffin wax emulsions have attracted more and more attention. People realize that using water instead of organic solvents as the carrier of wax products can greatly reduce the harm to the ecological environment, so the development and utilization of emulsified waxes have broad prospects. For wax, there are problems that paraffin wax is not easy to emulsify, the em...

Problems solved by technology

People realize that using water instead of organic solvents as the carrier of wax products can greatly reduce the harm to the ecological environment, so the development and utilization of emulsified waxes have broad prospects. For wax, there are problems that paraffin wax is not easy to emulsify, the emulsion is unstable and has a high viscosity. However, emulsified wax products with high solid content and good fluidity are more and more valued by the market because of their superior performance and reduced transportation costs, and the demand continues to increase. , the traditional preparation process has been difficult to meet the preparation requirements, so the present invention proposes a high-solid-content paraffin emulsion production process, which can effectively solve the above problems
