Abstract

The invention discloses a high-carbon alcohol emulsion type defoaming agent and a preparation method thereof. The defoaming agent is prepared from the following raw materials in parts by mass: 2 to 5 parts of palmitic acid, 0.2 to 0.6 part of propylene glycol, 4 to 10 parts of n-caprylic alcohol, 6 to 20 parts of pentaerythritol ester stearate, 5 to 12 parts of hexacosyl alcohol, 12 to 30 parts of microcrystalline wax, 2.5 to 7.5 parts of an emulsifier, and water. The defoaming agent is of an emulsion shape containing multiple high carbon alcohols, and has a defoaming effect. In addition, compared with an organic silicon defoaming agent and a polyether defoaming agent, the high-carbon alcohol emulsion type defoaming agent obviously reduces the cost.

Description

technical field [0001] The technical field of the defoamer of the present invention particularly relates to a high-carbon alcohol emulsion type defoamer and a preparation method thereof. Background technique [0002] Foam needs to be used in flotation, fire extinguishing, dust removal, washing, manufacturing foam ceramics and foam plastics, etc.; while in fermentation, coating, papermaking, printing and dyeing, removing flatulence of internal organs, boiler water, wastewater treatment and prism or glass manufacturing process It is necessary to eliminate foam in the environment, visible foam and foam are accompanied by people's production and life. The so-called "bubbles" or "bubbles" are formed by insoluble gases existing in liquids or solids or surrounded by their films. It is a dispersion system with gas / liquid, gas / solid, gas / liquid / solid interfaces , Dispersed bubbles at the gas / liquid / solid interface are commonly seen in ore dressing and oilfield systems. The accumula...
