Synthesis and Application of Sodium Acrylate

The synthesis methods mainly include bulk polymerization, solution polymerization, suspension polymerization and emulsion polymerization, and the polymerization process is essentially free radical polymerization. In the inverse emulsion polymerization of sodium polyacrylate, the polymer monomer uniformly forms countless small polymerization reactors, which are isolated from each other and dispersed stably in the emulsion. Compared with other polymerization methods, it has the advantages of higher yield and instant product dissolution. , has broad industrial application prospects.

Sodium Acrylate has different uses according to the difference in relative molecular weight. It can be divided into low relative molecular weight sodium polyacrylate (about 1000~5000), mainly for dispersion; medium relative molecular weight (about 104~106), mainly for Thickening effect; high relative molecular weight (about 106~107), mainly plays a role of flocculation.

The synthesis of low molecular weight Sodium Acrylate usually adopts an aqueous solution method, and there is no strict requirement for sodium acrylate monomer, but purification is required for special purposes. The amount of initiator used in the synthesis is relatively large, and the specific amount varies according to the synthesis process. The general amount is 0.5%~3.0% of the relative monomer mass; The temperature is as high as 135°C, and solid products can be synthesized directly.

Sodium Acrylate with low relative molecular weight has a wide range of uses, especially sodium polyacrylate with a relative molecular weight less than 2×104 is more rapidly applied, and is mainly used as water-soluble surfactants and detergent builders in the field of daily chemical industry. Because sodium polyacrylate has the effect of chelating multivalent ions, dispersing dirt aggregates and calcium soap, it has a strong adsorption force on dirt particles and can improve the detergency of anionic surfactants. Moreover, it has good thermal stability, strong resistance to cold water and hard water, and high degree of biodegradation; it can partially replace sodium tripolyphosphate in special detergents and cleaning powders to reduce environmental pollution. Sodium Acrylate with low relative molecular weight has good water solubility and high polarity, and can combine multivalent ions such as calcium and magnesium in water to form soluble chain anion bodies, so it is widely used in industrial heat exchange equipment. It is mainly used as boiler anti-scaling and anti-scaling agent. The low relative molecular weight sodium polyacrylate with a relative molecular weight of 500~5000 mainly acts as a dispersant. Used as a viscosity reducer and drilling mud stabilizer in the field of oilfield chemistry in the petroleum industry; used as a pigment dispersant in the paint, paper, ceramics and textile industries; in addition, used as a new type of quenching agent in metal materials; used in the rubber industry As a thickener; as an anti-caking agent in inorganic salts such as ammonium chloride; as a mineral flotation agent in mining. It is also used in food, industry, leather industry, printing industry, plastic industry, medicine, pharmacy and metal recovery of metal ion waste liquid.

More is the aqueous solution polymerization method. The quality requirements for acrylic acid monomers are relatively high, and the amount of initiator required is small, generally 0.01%~1.00% of the relative monomer mass; the reaction temperature should be lower at 20°C~60°C, and a suitable one should be selected. pH and monomer concentration. The acrylic acid is neutralized with NaOH solution to pH 10.5~11.0 after distillation to remove the polymerization inhibitor, and the initiator, anti-crosslinking agent fatty acid salt and retarder aniline compound are added; Polymerization at high temperature, the obtained colloid is dried in vacuum and crushed to obtain the product.

Acrylic acid is neutralized with sodium hydroxide solution, refined by cation exchange resin to prepare a quantitative concentration solution, and adjusted to pH = 10; under the condition of nitrogen flow, add 0.1% monomer mass of ammonium persulfate and 0.05% sodium bisulfite , Stir evenly and pour into the stainless steel tank. Stand still at 30°C to initiate polymerization, and use a 20°C water-cooled steel tank to remove the heat of polymerization in the lower part, so that the system temperature does not exceed 60°C, and keep warm for 2 hours to obtain a sodium acrylate glue with a relative molecular mass of more than 10 million.

Sodium Acrylate with medium and high relative molecular weight is easily soluble in water, and its COO-adsorption and the influence of steric effect on the structure make a small amount of positively charged ions in the solution precipitate out in the form of precipitation. Therefore, sodium polyacrylate with medium and high relative molecular weight can be used as a flocculant in the purification of electrolytic salt water, the separation of red mud in alumina production, and the treatment of industrial sewage. Sodium Acrylate with medium and high relative molecular weight has special effects on the flocculation of animal and plant proteins in biology, and can be used to recover a large amount of protein in food industry wastewater. Sodium polyacrylate with high relative molecular weight can produce a wide range of viscosity and fluidity, low addition amount can produce high viscosity, and the product viscosity is less affected by the ambient temperature. It can also permanently suspend insoluble components in the system, which helps to improve the stability of the product and prolong the storage period of the finished product. Therefore, it is often used as a thickener for cosmetics (such as facial masks, skin creams, etc.) in the daily chemical industry, and plays a very important role in the stability of cosmetic emulsions. Curative cosmetics tend to be more functional and diversified; use its film-forming properties to make hair styling agents, gel water, etc. It can also be used as a food preservative. Because medium and high sodium polyacrylates are non-toxic and soluble in water, they can be removed by washing before eating. Moreover, sodium polyacrylate can form a layer of polymer film on the surface of food, which can isolate food from air. The chelating effect of sodium polyacrylate on metal ions also helps to prevent food from spoiling. In the field of oilfield chemistry in the petroleum industry, it can be used as a viscosifier for drilling fluid, fluid loss reducer and clay stabilizer; in metallurgy, it can be used as a sand binder in the casting process to make the sand mold durable and of good quality; in textiles On the one hand, it can be used to modify synthetic fibers to make the printing and dyeing of chemical fibers firm, light-resistant and bright; it can be added to the ceramic body as a ceramic slurry water reducer, and it can enhance the dry strength of the body to a certain extent. In addition, it can also be used as a binder for wall materials, an anti-floating agent for pesticides, a thickener for acidifying liquids and pharmaceuticals, etc.

Functional Materials Modified by Sodium Acrylate

Jiang Xueliang took nitrile rubber (NBR) as the matrix, added sodium acrylate (NaAA) and dicumyl peroxide (DCP), and prepared water-swellable rubber (WSR) through in-situ polymerization. When the amount of NaAA increased, the water absorption and tensile strength of WSR also increased. [3]

Ren Wentan synthesized sodium acrylate (NaAA) in-situ in EPDM through the neutralization reaction of sodium hydroxide (NaOH) and acrylic acid (AA), and mixed the resultant under the action of organic peroxide The glue is vulcanized. The performance of in-situ synthesis of NaAA modified EPDM is better than that of EPDM directly added with NaAA or PNaAA. It not only has good mechanical properties, but also has good water swelling properties; The water-swelling properties are all improved; when the water-swelling rubber is 30 parts by mass of NaAA, the mechanical properties have the maximum value. [4]

Cao Wenzhong prepared agar, sodium acrylate-acrylamide superabsorbent composite materials by aqueous solution polymerization. The prepared composite material has good repeated liquid absorption and salt resistance. [5]

Leyan uses N-isopropylacrylamide (NIPAM) and sodium acrylate (SA) as hydrogel polymerization monomers, and uses initiator ammonium persulfate (APS) and cross-linking agent N,N-methylenebis(propylene Amide) (MBA) physically cross-linked monomers, and different poly-N-isopropylacrylamide-sodium acrylate hydrogels (NIPAM/SA) were prepared by changing the concentration of each component. The salt return amount of the hydrogel absorbent is zero, and the hydrogel absorbent can completely overcome the problem of particle back seepage caused by the liquid absorbent, and has a positive effect in the field of forward osmosis.
