Abstract
A super-strong water-absorbing resin is prepared from high-purity acrylic acid (60%), sodium hydroxide (27.2%), plant starch (9.7%), potassium persulfate (0.2%) and deionized water (2.9%). Its advantages are high water-holding nature, hygroscopicity and ammonia absorption power, no poison and irritation, and high storage stability.
Description
The present invention relates to a kind of super-strong water-absorbing material, specifically is a kind of High hydrophilous resin, belongs to novel high polymer polymeric material technical field.
The water-absorbing material in the technology formerly, as absorbent cotton, sponge, paper powder etc., its water-retaining capacity only is 10～20 times of deadweight, and water-retaining capacity is lower, and simultaneously, absorption speed is slower, can not repeat to reclaim and use.
Purpose of the present invention is to provide a kind of novel water-absorbing material---High hydrophilous resin, and its water-retaining capacity tool is breakthrough, can reach the hundred times to thousand times of deadweight.
The present invention is by the following technical solutions:
A kind of High hydrophilous resin is made up of high purity acrylic acid, sodium hydroxide, plant amylum, Potassium Persulphate, deionized water.Its concrete formulation ratio is:
High purity acrylic acid: 60%
Sodium hydroxide: 27.2%
Plant amylum: 9.7%
Potassium Persulphate: 0.2%
Deionized water: 2.9%
With high purity acrylic acid and 93% analytically pure sodium hydroxide weighing, in water, neutralize, the cooling back adds plant amylum (as Semen Maydis powder), Potassium Persulphate, stir, feed nitrogen, be heated to 40 ℃ (becoming translucent slurry), put into pottery after the proposition, be heated to 50 ℃, polymerization.Cooling is cooled off after drying, is crushed to 100 orders.
The water-retaining capacity of High hydrophilous resin is breakthrough a kind of of tool in present water-absorbing material, can expand rapidly after its suction, in several minutes, just can absorb self 750～1000 times water, thereby reach 100% water-intake rate, after its drop is discharged water, can also use repeatedly.Present glittering and translucent shape after the suction.The reason that its water-retaining capacity is strong is to have hydrophilic group, and inside is tridimensional network.When dry, it aggregates into one, when hydrophilic group runs into water molecules, because the principle that positive negative is inhaled attracts water molecules layer by layer, reaches the purpose of suction.
Embodiment: high purity acrylic acid 60 grams and 93% analytically pure sodium hydroxide 27.2 grams are neutralized in 78 gram water, the cooling back adds Semen Maydis powder 10 grams, Potassium Persulphate 0.2 gram, stir, feed nitrogen, be heated to 40 ℃ (becoming translucent slurry), put into pottery after the proposition, be heated to 50 ℃, polymerization.Cooling is cooled off after drying, is crushed to 100 orders.
High hydrophilous resin has very high water-retentivity, and when adding the pressure of 70 gram/square centimeters, normal Mierocrystalline cellulose and other material almost can all be emitted adsorbed liquid, and multipotency keeps 25%, and this material can keep 75～85%.
High hydrophilous resin has the certain moisture surname, and humidity increases in the air, and it can absorb moisture, and it discharged moisture again when humidity reduced, and therefore can regulate airborne humidity automatically.
High hydrophilous resin has the ammonia of suction ability, helps the deodorizing of sanitary towel, paper nappy, the utilization ratio of nitrogenous fertilizer in the soil can also be improved.
High hydrophilous resin has dividing a word with a hyphen at the end of a line property of volatilization, and when its hydrogel contacts with soil, air etc., the moisture in the gel has dividing a word with a hyphen at the end of a line property of the volatilization formation suction balance of dewatering, and this function can be used for agricultural gardening etc.
The High hydrophilous resin nontoxicity.Through the mouth eye test to animal, provable product is nontoxic, non-stimulated, nothing is irritated, no antigen, none death of animal.
High hydrophilous resin has package stability, and isolated when itself and air, excellent storage stability under the normal temperature can be stored several years continuously.
High hydrophilous resin has plyability, it can with urethane, polyvinyl chloride, modified poly-epoxy ethane, ethene---acetate ethylene copolymer; blend such as styrene-butadiene rubber(SBR), chloroprene rubber, natural rubber; improve its swelling property, flexibility, processibility, antifog property, stopping property and usability repeatedly, these product water-intake rates are generally several times to 200 times.Can be used as expandable material, sealing material and civil construction material.
The excellent specific property of High hydrophilous resin makes its multinomial field that is widely used in national economy, as multiple industries such as agricultural, forestry, gardening, health, oil, buildings,
