Problems solved by technology

The advantage is that the process is simple, and the disadvantage is that the use of cationic surfactants is unstable and the stability of the solution cannot be guaranteed, and the use of aluminum sulfate has an impact on the environment
[0005] Chinese patent CN 102766336 A discloses a paraffin wax emulsion and its preparation method. The paraffin wax emulsion is prepared by the nascent soap method according to a certain proportion of paraffin wax, stearic acid, and ammonia water. The advantage is that the process is simple and the cost is low. The disadvantage is that the paraffin wax emulsion has a high viscosity. Uncontrollable, poor stability, and serious ammonia smell, affecting the performance of the product

Abstract

The invention discloses low-viscosity and high-stability paraffin emulsion and a preparation method thereof, and belongs to the field of chemical products. The low-viscosity and high-stability paraffin emulsion is prepared from the following components in percentage by weight: 30 to 35 percent of paraffin, 1.8 to 3.5 percent of a surfactant A, 2.6 to 3.9 percent of a surfactant B, 0.4 to 1 percentof a surfactant C, 0.1 to 0.3 percent of a surfactant aid, 0.2 to 0.5 percent of a stabilizer, 0.1 to 0.3 percent of a defoaming agent, 0.1 to 0.3 percent of an environment-friendly bactericide and the balance of deionized water, wherein the sum of weight parts of all the components is 100 percent. By selecting proper surfactants, aid and stabilizer and suitable technological conditions and adopting a D-phase emulsification process, the low-viscosity and high-stability paraffin emulsion is prepared. The low-viscosity and high-stability paraffin emulsion has the advantages of low viscosity, small particle size, long storage time, good stability and the like.

Description

technical field [0001] The invention relates to the field of chemical products, in particular to a low-viscosity, high-stability paraffin emulsion and a preparation method. Background technique [0002] Paraffin emulsion is a chemical product with a wide range of uses. Generally, low-concentration paraffin emulsion is used as an auxiliary agent for latex products in the pharmaceutical industry; it is used for fruit preservation in agriculture. High-concentration paraffin wax emulsion, because of its high wax content, better coverage, low cost of use, and wider application range, such as used as a curing agent for reinforced concrete in the construction industry; used as a pulp sizing machine in the paper industry; Used as a dispersant in printing inks; used as a finishing agent in the leather industry, etc. At present, the research and production of paraffin emulsion in my country is still relatively extensive, with small production scale and few varieties, which cannot me...
