Problems solved by technology

[0006] The purpose of the present invention is to overcome the problem that the existing dispersant for polyacrylamide granulation is attached to the surface of polyacrylamide colloidal particles, because the dispersant cannot be completely baked out, thereby affecting the solubility of polyacrylamide products. Provide a novel dispersant composition

Embodiment 1

[0030] A mixture of 97 parts by weight of kerosene with a specific gravity of 0.78, 1 part by weight of polyoxyethylene sorbitan fatty acid ester (Tween) and sorbitol fatty acid ester (Span) (wherein, polyoxyethylene sorbitan fatty acid ester The weight ratio of acid ester to sorbitol fatty acid ester is 1:1), 2 parts by weight of dodecylamine sulfonate maleate were added into the reaction kettle and stirred for 4 hours to prepare dispersant composition F1. The relevant physical and chemical performance parameters of the dispersant composition are shown in Table 1.

[0031] During the polyacrylamide colloidal granulation process, the dispersant composition F1 prepared by the above formula is added to the dispersant oil tank, and evenly sprayed onto the polyacrylamide granules through the high-pressure oil pump through the delivery pipeline to realize continuous production.

Embodiment 2

[0033] 99 parts by weight of kerosene with a specific gravity of 0.85, 0.9 parts by weight of polyoxyethylene sorbitan fatty acid ester (Tween), and 0.1 parts by weight of dodecylamine sulfonate maleate were added to the reactor and stirred for 4 hours , to prepare dispersant composition F2;

[0034] During the polyacrylamide colloidal granulation process, the dispersant composition F2 prepared by the above formula is added to the dispersant oil tank, and evenly sprayed onto the polyacrylamide granules through the high-pressure oil pump through the delivery pipeline to realize continuous production.

Embodiment 3

[0036] 95 parts by weight of kerosene with a specific gravity of 0.8, 2 parts by weight of sorbitol fatty acid ester (Span), and 3 parts by weight of dodecylamine sulfonate maleate were added to the reactor and stirred for 4 hours to prepare a dispersant combination Material F3; The relevant physical and chemical performance parameters of this dispersant composition are as shown in Table 1.

[0037] During the polyacrylamide colloid granulation process, the dispersant composition F3 prepared by the above formula is added to the dispersant oil tank, and the high-pressure oil pump is evenly sprayed onto the polyacrylamide granules through the delivery pipeline to realize continuous production.

Abstract

The invention discloses a dispersant composition, which is characterized in that the dispersant composition is mainly composed of light oil, a surfactant and a conditioner, and based on 100 parts by weight of the dispersant composition, the light oil The content of the surfactant is 85-99 parts by weight, the content of the surfactant is 0.9-5 parts by weight, the content of the regulator is 0.1-10 parts by weight, and the regulator is C10-C18 in the maleic acid monoalkylamine sulfonate any one or more of. Using the dispersant composition of the present invention, when the polyacrylamide granules are granulated, after the dispersant composition is attached to the surface of the polyacrylamide micelle, the granulated polyacrylamide micelle can be efficiently dispersed without sticking. Knot, and without changing the hydrolysis and drying conditions of the polyacrylamide colloidal particles, the dispersant composition can basically be completely baked out, thereby improving the solubility of the polymer polyacrylamide.

Description

technical field [0001] The invention relates to a dispersant composition and the application of the dispersant composition in the polyacrylamide granulation process. Background technique [0002] In the production process of polyacrylamide, the polyacrylamide colloid is usually crushed into particles and then dried and sieved. Before drying, in order to keep the freshly granulated colloids dispersed efficiently and no longer bonded, it is necessary to use Dispersant. [0003] In the existing patent reports related to polyacrylamide dispersants, patent CN101508933A discloses a polymer lubricating oil dispersing aid, which is characterized in that the weight percentage of its ingredients is composed of: light oil 75-85%, emulsified 5-8% of agent, 2-3% of stabilizer, 7-8% of solubilizer and 3-6% of surfactant. [0004] Patent CN1498677A discloses a dispersant for colloid granulation, which is characterized in that this system contains soap, kerosene and water, and its weight ...
