Abstract
The present invention relates to a method for preparing composite super water-absorption material by radiation, which belongs to the field of the preparation of high molecular materials. At present, the high water-absorption materials are all prepared from traditional raw materials in petrochemical industry by chemical methods and have complicated technology and high cost. In the present invention, a new method for preparing the composite super water-absorption material by radiation, which uses a bentonite material is developed. The present invention has the advantages of low cost, simple technology and no three waste generation. Meanwhile, water-absorption materials with controllable water-absorption multiples can be synthesized according to different application requirements of soil water retention, water plugging on oil fields, articles for daily use, etc. by the present invention.
Description
Radiation prepares the method for super composite absorbent material.
The invention belongs to macromolecule material preparation area.
High-absorbent material is the novel material that grew up in recent years, and 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,, become the main goal of attack of modern chemistry chemical field so strengthen research and development and comprehensive utilization to various resources.
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 air atmosphere, 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:
Dry powder weight before dry powder weight/suction before weight-suction after suction multiple=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.
Wilkinite dry powder is mixed with 30% the aqueous solution, placed 24 hours in room temperature, 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.
