Embodiment 1

[0026] Mix 69.8g of deionized water and 0.1g of Tween 80, and stir for 15min at a stirring speed of 3000r / min;

[0027] Then add 0.5g hydrogen peroxide, 1g liquid paraffin, 20g butyl oleate, 4g dodecyl alcohol ester, 0.1g Span 80, 0.2g n-octanol and 3g dimethyl silicone oil and continue to stir evenly, at a stirring speed of 2000r / min After stirring for 20min, stop stirring and discharging to obtain the anti-sticking agent for super absorbent resin gel;

[0028] Pour the anti-sticking agent into the watering can, spray 5g of the anti-sticking agent on the surface of 100g of super absorbent resin gel, cut into strips, extrude and granulate by screw, dry, pulverize and sieve to obtain 60-100 mesh super absorbent The properties of the resin are shown in Table 1.

Embodiment 2

[0030] Mix 58.8g of deionized water and 1g of Tween 80, and stir for 15min at a stirring speed of 3000r / min;

[0031] Then add 1.5g of hydrogen peroxide, 5g of liquid paraffin, 30g of butyl oleate, 8g of dodecyl alcohol ester, 1g of Span 80, 0.8g of n-octanol and 5g of dimethicone and continue to stir evenly, stirring at a stirring speed of 2000r / min After 30 minutes, stop stirring and discharging to obtain the anti-sticking agent for super absorbent resin gel;

[0032] Pour the anti-adhesive agent into a watering can, spray 10g of anti-adhesive agent on the surface of 100g of super absorbent resin gel, cut into strips, extrude and granulate by screw, dry, pulverize and sieve to obtain 60-100 mesh super absorbent The properties of the resin are shown in Table 1.

Embodiment 3

[0034] Mix 62g of deionized water and 0.5g of Tween 80, and stir for 15min at a stirring speed of 3000r / min;

[0035] Then add 1g of hydrogen peroxide, 2g of liquid paraffin, 25g of butyl oleate, 6g of dodecyl alcohol ester, 0.7g of Span 80, 0.5g of n-octanol and 4g of dimethicone and continue to stir evenly, stirring at a stirring speed of 2000r / min After 25 minutes, stop stirring and discharging to obtain the anti-sticking agent for super absorbent resin gel;

[0036] Pour the anti-sticking agent into the watering can, spray 7g of the anti-sticking agent on the surface of 100g of super absorbent resin gel, cut into strips, extrude and granulate by screw, dry, pulverize and sieve to obtain 60-100 mesh super absorbent The properties of the resin are shown in Table 1.

Abstract

The invention provides an anti-adhesion agent for superabsorbent resin gel and a preparation method thereof. The preparation method comprises mixing deionized water and an emulsifier A for some time, adding hydrogen peroxide, liquid paraffin, butyl oleate, 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate, an emulsifier B, an antifoaming agent and dimethicone, carrying out uniform stirring for some time, stopping stirring and then discharging the mixture as the anti-adhesion agent for superabsorbent resin gel. The preparation method has simple processes, is nontoxic and harmless, effectively prevents adhesion of superabsorbent resin gel to a cutter blade and other stainless steel devices, prevents equipment rusting and is conducive to aqueous solution polymerization-based industrial production of superabsorbent resin.

Description

technical field [0001] The invention relates to an anti-adhesive agent, in particular to a super-absorbent resin gel anti-adhesive agent and a preparation method thereof. Background technique [0002] Super Absorbent Resin (SAP) is a new type of polymer material that can absorb hundreds or even thousands of times its own weight in water. Compared with traditional water-absorbing materials such as sponge, silica gel and calcium chloride, super absorbent resin has the advantages of large water absorption capacity, fast water absorption rate, strong water retention capacity, safety and non-toxicity, etc., so it is widely used in sanitary and medical materials, agricultural Horticulture, soil improvement, environmental protection and civil construction and other industries have received more and more attention. Among them, polyacrylic acid super absorbent resin (Zhang Xiaolei. Research on the preparation and surface crosslinking of super absorbent resin [D]. South China Univers...
