The raw material of the nuclear powder-acrylonitrile graft polymer, because it contains the higher polymer-starch, it is expected to be rotten=two can not be preserved for a long time; further, the manufacturing method is very complicated, -, " twins Kochi's preparation method is the most economical with the use of acrylic acid and acrylate to crosslink polymerization. The reason is that the acrylate copolymer Λ, _ special 枓 - acrylic acid can be quickly purchased from the market, and the obtained 鬲 water-absorbent resin has: water absorption capacity of the negative 偎鬲, and has low manufacturing cost and 曰 4 rot The decomposition of hydrazine is the most economical, so it has become the most popular high-absorbent 6 200900439 water-based resin. The method of polymerizing acrylic acid and acrylate to form a superabsorbent resin can be obtained by several known methods such as water-reduction polymerization, reverse phase fresh liquid polymerization, emulsion polymerization or pouring or coating a monomer onto the filament f. A method such as a polymerization reaction is carried out. In these methods, the reverse phase suspension polymerization and the emulsion polymerization must use organic lysate, but if the temperature of the anti-scale is not effectively controlled, the organic V' dissolution should be increased by the system temperature and pressure. The cockroaches and even the secret explosions threaten the safety of the personnel on the operating site and cause environmental pollution. ^ The finished product also has doubts about the residual organic solvent. The hydrophilic polymer dissolved in the superabsorbent resin forest has a uniform bridge structure inside, and generally improves the quality such as: (4) rate, improvement of colloid strength, reduction of agglomeration, liquid permeability, etc. In the raw silk acrylic high-absorbency tree, the heat treatment method cross-links the surface of the resin-based resin to reduce the water-absorbent resin from being hydrated by the aqueous liquid to form a gel and agglomerate. When the water-absorbent brain table _ Cheng Ningke, New Zealand (four) ship water _ grease surface to the Xia Xia Li, will also = sex ship tenderness, technology - she earns the absorption capacity of resin. The technique of Xu Yi Lai Gao, who is the leader of the technology industry, has been opened up for two methods, such as: Dispersing (4) Waterborne Resin Co., Ltd. in the surface of the cross-linking process (JP_A—56—131608, JP Yang, 27 , JP+58_42602, 7 200900439 JP-A58-U7222 ) 'Inorganic powder directly mixed the cross-linking agent and cross-linking agent solution into the superabsorbent tree mystery (P-A6 (M63956 m255814)), after adding cross-linking d ?Subtractive treatment (JP-A-H134Q6) 'Use of organic solvents, water and polyols for '4 treatment (JP-A-63-27G74WP-A-64-50707, IP-A-1-292004), ^ with organic Solution, water, (ether) compound Up_A_2-1539Q3), using a sulphur-glycol-based, polyfunctional amine such a bifunctional compound (US Patent 4' _, No. 983) and adding polyol as inert A method in which a solvent absorbs a water-absorbent resin (U.S. Patent No. 4,507,438, 4,541,871), and a surface-crosslinking solvent is mixed with a water-absorbent resin using a high-speed mixer (U.S. Patent 5, 140'_ No.), also using N-(alkyl)-methylaminopropionic acid g to spray on the surface of the water-absorbent resin for heat treatment (money Lie 5, 229, spare number), and the method of heat treatment using alkylene carbonate (U.S. Patent No. 5, 働, No. 771), etc., other public finances regarding the surface cross-linking of superabsorbent resin _ patent; Specialized Bu Li 4298814, 4295978, 4500670, 4732968, 4758617, 4824顚, 4954562 and 5026800, these heat treatment of the US patent method _ speed, that is, the lifting force under the lifting force, but will be more than the rest of the (four) Consequences, reducing the performance of the actual application. SUMMARY OF THE INVENTION The present invention provides a method for producing a super absorbent resin in the above-mentioned invention, wherein the method b has an absorption capacity of ασ and an absorption ratio under pressure, and a low gel blocking phenomenon, so that the absorbent article It has easy drying and low frosting. 8 200900439 A water-soluble unsaturated monomer required for producing the super absorbent resin of the present invention, in addition to a dibasic acid, other water H monomers having an acidic group-unsaturated double bond such as methacrylic acid, Marlinic acid, fumaric acid, 2-acrylamide-2-mercaptopropyl acid, cis-butane diacid, maleic anhydride, anti-butadiic acid, fumarate, etc.: single The selection of the body is not limited to only one type, and a plurality of monomers may be used together. It is also necessary to add other hydrophilic monomers having an unsaturated surface, such as acrylamide, methacrylamide, or the like. 2-Carboxyethyl acrylate, 2-carboxyethyl methacrylate, Methyl acrylate, Ethyl acrylate, Dimethylamine propylene decylamine, Propylene propylene acrylamide tris-ammonium (US Patent 4, 057, 521) No. 4, 〇62 幻7, 4, 525, 527, 4, 286, 082 and 4, 295, 987), but the addition amount is based on the principle of not impairing the physical properties of the superabsorbent resin. Before the radical polymerization, the concentration of the aqueous monomer solution is preferably controlled between 20% by weight and 55% by weight, and the appropriate concentration is between 30% and 45% by weight. When the concentration is less than 1% by weight, the concentration is less than 2%. The hydrated body is too soft and sticky. It is unfavorable for mechanical processing. The added concentration is above 55 wt% by weight, close to the saturation concentration, difficult to formulate and the reaction is too fast. The reaction heat is not easy to control. The carboxylic acid group of the acid group-containing monomer should be partially neutralized to control the pH of the finished product, so that the neutral or slightly acidic 'neutralizer' is an alkali metal or alkaline earth hydroxide or a phenolic acid compound in the periodic table. For example, sodium hydroxide, potassium hydroxide, sodium carbonate, carbonic acid clock, sodium hydrogencarbonate, potassium hydrogencarbonate or ammonia compound; the neutralizing agent may be used alone or in combination of one or more. The slow acid group of the acid group-containing monomer is neutralized to form a sodium or potassium salt or a money salt, and the percentage of neutralized wave molars is 45 m. Job δ5_, should be secret to 75mol% 'The concentration of neutralization concentration is 45_ or less, the value of the finished product will be low, and the percentage of neutral concentration of the molar is 85111〇1% or more. The pH value of the finished product will be high. When the PH value of the finished product is not neutral or slightly acidic, if it is inadvertently in contact with the human body, it is not suitable for 'the car is not safe. Before the radical polymerization reaction, a water-soluble polymer may be added to the aqueous monomer solution to reduce the thief, such as a part of the pure shirt holographic polyvinyl alcohol, polyethylene glycol, polyacrylic acid, Polypropylene _, powder or temple powder derivatives such as fluorenyl cellulose, yttrium acrylate cellulose, ethyl cellulose and other polymers; the molecular weight of these water-soluble polymers is not limited, the towel is more water soluble The polymer is starch, partially saponified or fully saponified polyvinyl alcohol or the like, used alone or in combination. The water-absorbent resin preferably has a weight percentage of the water-soluble polymer added to 2020% by weight, but preferably from Q to i〇wt% is preferably 〇 to 5wi:%, and the addition of more than 2% by weight may affect Physical properties make physical properties worse. Before the radical polymerization reaction, a radical polymerization crosslinking agent should be added to the unreacted monomer solution. The radical polymerization crosslinking agent can be selected from compounds having two or more unsaturated double bonds, such as: N. ,N,-bis(2-propenyl)amine, hydrazine, Ν'-methine bis acrylamide, N,N,-decyl bis-decyl acrylamide, acryl acrylate, ethylene glycol diacrylate Ester, polyethylene glycol diacrylate, ethylene glycol dimercapto acrylate, polyethylene glycol dimethacrylate, glycerin triacrylate, glyceryl dimethyl propionate, glycerin plus epoxy Tripropylene acid g or dimercaptopropyl 10 200900439 enoate, dimethanol propane plus ethylene oxide triacrylate or tri-p-acrylate, di-methanol-propylated di-t-propionate, three Alcohol-acrylic triacrylate, N, bis(2-propenyl)|female, ethylene glycol monoacrylate, polyoxyethylene glyceryl triacrylate, diethyl polyoxyethylene glyceryl diacrylate, dipropylene A glycol ester or the like can also be used as a compound having two or more epoxy groups, such as Phenol polyglycidyl ether, polyglycerol polyglycidyl ether, ethylene glycol diglycidyl ether, diethylene glycol diglycidyl ether, polyethylene glycol diglycidyl ether, diglycerin polyglycidyl ether, etc. . After the radical reaction, the superabsorbent resin can have an appropriate degree of crosslinking, and the water-absorbent resin colloid can have appropriate processability. The radical polymerization crosslinking agent may be used singly or in combination of two or more. The free radical polymerization cross-linking agent is appropriately added between 5% and 5% by weight of 彳·〇〇1 (based on the total solids of the reactants), and a more appropriate amount by weight is in Q. _% Between 3wt%. The dosage is 5% by weight or less. 001 wt% or less The hydrate is too soft and viscous after polymerization. Unfavorable mechanical processing, the amount of the additive is less than 5% by weight, and the water absorption is too low, which lowers the resin properties. The polymerization of the present invention produces a free radical t from the decomposition of the free radical polymerization initiator. Free radical start 胄彳 optional 贞 hot split cap starter 'suitable thermal decomposition type starter has peroxide, such as: hydrogen peroxide, di-tert-butyl peroxide, guanidinium peroxide Or persulfate (ammonium salt, alkali metal salt), etc., and azo compounds such as: 2.2'-azobis(2-amidinopropane) dihydrochloride, 2.2,-azobis (n, n_ - Dimethyl sulfonate dihydrochloride; can also be used as a redox 200900439 type initiator, such as: acid sulfite, thiosulfate, ascorbic acid or ferrous salt; or will be oxidized The reduction type and the heat separation initiator are combined. First, the redox initiation is carried out to generate a radical, and when the self-domain is transferred to the monomer, the polymerization reaction is initiated, and as the polymerization proceeds, a large amount of heat is released to raise the temperature, and when the temperature reaches the thermal decomposition type. When the decomposition temperature of the initiator starts, the second stage of thermal decomposition is initiated, which causes the whole polymerization to be more complete. The appropriate amount of the radical polymerization initiator is from 5% by weight (based on the weight of the neutralized acrylate), and the appropriate amount is between 伙 and 5% to 5% by weight 〇 〇〇1. When the reaction is too slow, the economic effect is not good. When the percentage of the job is 1Qwtte, the reaction is too fast and the reaction heat is not easy to control. The polymerization reaction of the present invention can be carried out in a conventional batch reaction vessel or on a conveyor belt reactor, and the superabsorbent resin obtained by the reaction is first cut into a small gel body having a diameter of 20 mm or less by a mincer, and the diameter is 1 〇mm or less is better, and then screening.
