Abstract
Radiation prepares the method for super composite absorbent material.The invention belongs to the preparation field of macromolecular material.
At present, high-absorbent material all is to use the petrochemical complex traditional raw material, adopts chemical process to be prepared from, its complex process, and cost is higher.The present invention has explored the novel method that a kind of width of cloth is penetrated the super composite absorbent material of preparation, and what it used is the wilkinite material, and with low cost, technology is simple, does not produce the three wastes.It can be according to soil water-retaining simultaneously, needs of different applications such as Water in Water Shutoff in Oil Field and daily necessities, the controlled water-absorbing material of synthetic suction multiple.
Description
The invention belongs to macromolecule material preparation area.
High-absorbent material is the novel material that grew up in recent years, it has the water-retaining capacity height, and good water-retaining property, intensity are big, and advantages such as after-applied certain pressure does not dewater absorb water.It is in industry, agricultural, Water in Water Shutoff in Oil Field, afforestation, soil improvement, and all there is important application aspects such as daily life.High-absorbent material is to adopt chemical method to be prepared from the petrochemical complex traditional raw material.At present, prepare this high-absorbent material and be faced with the petrochemical complex traditional material supply falls short of demand and price increase, so strengthen having become to the research and development of various resources and condensation utilization, the main goal of attack of modern chemistry chemical field.
Purpose of the present invention, exactly in order to comply with these needs of chemical field, and explored the novel method that a kind of radiation prepares super composite absorbent material, compare with present chemical method, what it used is a kind of inorganic mineral (wilkinite) material, so the super composite absorbent material technology of this method preparation is simple, with low cost, the suction multiple is controlled, of many uses, does not produce advantages such as the three wastes.
To the effect that of the present invention: wilkinite is mixed with the bentonite solution of 10-50%, mixes with 30% acrylamide solution then, the ratio of wilkinite and acrylamide can be between 20: 80～80: 20.In mixing solutions, add the NaOH of 0.5-30% and the N-N methene base bisacrylamide of 1-2PPM, stir and form homogeneous semi-solid state system, under the atmosphere of air, pass through
60The effect of CO-gamma-rays is polymerized.Again the polymeric offset plate can be obtained different granulous products through operations such as granulation, oven dry, pulverizing.It can be according to needs of different applications such as soil water-retaining, Water in Water Shutoff in Oil Field and daily necessities, the different water-absorbing material of synthetic suction multiple.The suction multiple is pressed formula and is calculated:
Suction multiple=(dry powder weight before the weight-suction after the suction)/(dry powder weight before the suction)
The water-retaining capacity of synthetic water-absorbing material of the present invention is controlled at several grams/gram, tens gram/grams, several hectograms/gram, 1 kilogram/gram.
Be most preferred embodiment of the present invention below.
With wilkinite dry powder be mixed with 30% the aqueous solution, room temperature place 24 hours, it is fully absorbed water form semi-solid homogeneous system.Getting concentration and be 30% wilkinite solution 50 grams and 50, to restrain concentration be that 30% acrylamide mixes, add 4 gram NaOH and 0.5 ml concns simultaneously and be 3% methene base bisacrylamide, fully stir and form semi-solid homogeneous system, place it in then in 40 ℃ the thermostat(t)ed water
60Polymerization under the CO-gammairradiation, the dose rate of irradiation is selected in 5.3rad/s, total dose exists: 4.80 * 10
4Rad, the offset plate after the polymerization be through pulverizing, dry in 120 ℃ baking oven, and then to pulverize be No. 30 particle.Surveying its suction multiple is 820 gram water/1 gram dry powder.
Claims (5)
