Ammonium stearate emulsion and producing method thereof

Abstract

The invention relates to ammonium stearate emulsion and a producing method thereof, belonging to the technical field of auxiliary chemicals. The ammonium stearate emulsion comprises the following components with the weight percentage: 15-35% of stearic acid, 6-14% of 20% ammonia water, 1-3% of lauryl sodium sulfate and the rest of water. The production technique is that a reaction vessel is sequentially added with the stearic acid, the lauryl sodium sulfate and the water according to the formulation amount, the temperature is regulated to be 10-25 DEG C; after being evenly stirred, the mixture in the reaction vessel is added with the ammonia water, and the mixing speed is adjusted; the prepared ammonium stearate liquid is absorbed into an emulsifying tank for emulsification, stands still for 1-2h, and then is filtered, so that the ammonium stearate emulsion is obtained. The invention is suitable for large scale continuous production, ensures the reaction to be very safe under normal temperature and pressure, and has the advantages of simple input equipment, saved cost, no pollution and emission in the whole production process, silvery white and lustrous finished products, excellent fluidness and stability, low product viscosity (being lower than or equal to 350cps), high purity, good dispersion effect and convenient use. The ammonium stearate emulsion can be fully dispersed in waterborne liquid, has about six-month shelf life and is hard to become thick after being placed for a long time.

Description

technical field [0001] The invention belongs to the technical field of chemical additives, and in particular relates to an ammonium stearate emulsion and a production method thereof. Background technique [0002] The traditional production process of ammonium stearate is to react some components such as stearic acid at a relatively high temperature. In industrial production, there are disadvantages such as poor controllability and difficulty in guaranteeing product quality. The viscosity of the produced product is very high, generally at 8000cps -10000cps or so. Application number is the patent of 200710067469.7, discloses a kind of ammonium stearate and production method thereof, and its ammonium stearate component comprises stearic acid, sodium lauryl sulfate, coconut oil diethanolamide, 20% ammoniacal liquor and Water, the method is to mix the above components at room temperature, and then stir at different stirring rates. Compared with the traditional production method,...

Problems solved by technology

This method is simple to operate, and the viscosity of the prepared product has a certain reduction, and the viscosity is generally 3500cps-4500cps, but this method also has shortcomings. The emulsifier is used for emulsification and its mixer is used to stir and disperse the reaction, so that the product is not in the reaction process. Not completely emulsified, so its viscosity is still high, and it is easy to thicken after a long time, which affects the dispersion of the product
