Embodiment 1

[0021] A self-emulsifying rosin-based surfactant emulsion, its general structural formula is as follows:

[0022] R-PEG-R, in the formula, R is rosin or modified rosin, and the modified rosin is disproportionated rosin, hydrogenated rosin or polymerized rosin. PEG is low molecular weight polyethylene glycol with a molecular weight of 200 or 400.

Embodiment 2

[0024] The preparation method of self-emulsifying rosin-based surfactant emulsion, synthesis comprises the following steps:

[0025] Respectively take by weighing rosin and Polyethylene Glycol 400 that the molar ratio is 2: (1-1.1) and pour in the 500ml four-neck flask, then add appropriate amount of zinc oxide (the amount of zinc oxide accounts for about 0.1-0.2% of the rosin quality) ) as a catalyst, heated to 230-280°C to make it fully react, control the reaction process by measuring the acid value of the reactant, when the acid value drops to about 10, the reaction is basically completed, and the material is cooled and discharged.

[0026] Described rosin and polyethylene glycol reaction conditions are:

[0027] The mol ratio of rosin and Polyethylene Glycol is 2: (1-1.1), for example ratio is selected as: 2: 1, 2: 1.05, 2: 1.1, the consumption of zinc oxide can be selected 0.1%, 0.12%, 0.14%, 0.16%, 0.18%, 0.2%. React at 230-280°C for 5-8 hours, the reaction temperature...

Embodiment 3

[0038] Take by weighing respectively disproportionated rosin and Polyethylene Glycol 200 with a molar ratio of 2: 1.1 and pour them into a 500ml four-necked flask, then add an appropriate amount of zinc oxide (the amount of zinc oxide accounts for about 0.15% of the rosin quality) as a catalyst, and heat It is fully reacted at 230°C, and when the acid value drops to about 10, the reaction is basically completed, and the material is cooled and discharged.

Abstract

The invention discloses a self-emulsification rosinyl surfactant emulsion and a preparation method thereof. The preparation method comprises: esterfying polyethylene glycol of low molecular weight with rosin or modified rosin to prepare rosinyl polyethylene glycol diacrylate; in the presence of emulsification-assistant agent, emulsifying the rosinyl polyethylene glycol diacrylate to prepare emulsion of which the solid content is 30-60% with a high shear apparatus. The prepared self-emulsification rosinyl surfactant emulsion has smaller parameter diameter reaching 112nm, and good stability. The emulsion has strong surface activity, raw materials are cheap and easy to obtain, and environmentally-friendly water serves as dissolvent, thus the emulsion is biodegradable. The emulsion is an environmentally-friendly surfactant emulsion and can serve as emulsifier, dispersant and accessory ingredient in oil fields.

Description

technical field [0001] The invention relates to a rosin-based surfactant emulsion and a preparation method thereof, in particular to a self-emulsifying rosin-based surfactant emulsion and a preparation method thereof. Background technique [0002] Oil-soluble emulsifiers are difficult to handle in processing applications due to their high viscosity and poor fluidity. If the surfactant solution is formulated with an organic solvent, it will not only increase the cost, but also cause environmental pollution. Nanoparticles can easily penetrate the outer dura of the emulsion, destroy the molecular structure, and achieve the purpose of rapid emulsification, which cannot be achieved by ordinary emulsifiers. They can be automatically emulsified in a static state. The emulsification is faster and the emulsification effect is good. After the oil-soluble emulsifier is made into a nanoemulsion, it is not only convenient to process, but also environmentally friendly. [0003] Rosin h...
