A kind of composite surfactant containing quaternary ammonium salt and application thereof

Abstract

The invention discloses a compound surfactant containing quaternary ammonium salt and application thereof. The complex surfactant containing quaternary ammonium salt includes quaternary ammonium salt surfactant and oleoresin oil surfactant. The oleifera resin oil surfactant is prepared by the following method: (1) Mix the oleoresin oil and fumaric acid in a reaction kettle at a weight ratio of 1:0.2-0.5, and then adjust the temperature to 180-220°C React for 2 to 5 hours to obtain fumaric acid modified oleoresin oil; (2) Fumaric acid modified oleoresin oil, deionized water and xylitol in a weight ratio of 1:1 to 1.5 in the reaction kettle: Mix 0.3-0.6, add a catalyst whose weight is 2%-5% of the fumaric acid modified oleoresin oil, then adjust the temperature to 220-250°C for 3-5 hours, and get the oleoresin oil surfactant after cooling . The composite surfactant containing quaternary ammonium salt has very good dispersing and emulsifying ability for carnauba wax, and can easily disperse carnauba wax in water to form a stable carnauba wax emulsion.

Description

technical field [0001] The invention relates to the technical field of surfactant preparation, in particular to a composite surfactant containing a quaternary ammonium salt and an application thereof. Background technique [0002] Surfactant refers to a substance that can significantly change the interface state of its solution system when added in a small amount; A series of physical and chemical effects such as antistatic and antistatic are a kind of fine chemical products that are flexible and versatile. [0003] carnauba wax lotion It is a product prepared by emulsification technology based on carnauba wax as the main raw material; it is widely used in the manufacture of leather finishing agents, water-based inks, water-based paints, water-based paints, glazing agents, fruit preservation, and plastic and rubber lubricants, etc. . But due to lack of preparation carnauba wax lotion special surfactants, resulting in carnauba wax lotion In the preparation process, it is...

Problems solved by technology

But due to lack of preparation Carnauba Wax Lotion special surfactants, resulting in Carnauba Wax Lotion In the preparation process, it is often necessary to add a series of additives such as various surfactants, emulsifiers, dispersants, defoamers, and anti-settling agents, and the emulsification process is complicated and the conditions are harsh; and the conventional method prepared Carnauba Wax Lotion Long-term storage is unstable, prone to precipitation and flocculation stratification
