Abstract
A water absorbing and retaining agent is composed of acrylic acid, ammonia water, sodium oxychloride, zinc persulfate and is granular crystal in shape. Its prodn. technology is: raw material selection, compounding, react in reactor, discharging, product. Its advantages include scientific in designing, rational in composition, simple in prodn. technology, in addion, no reject product and no pollution to enviroment.
Description
The present invention relates to a kind of water-absorbing water-retaining agent and production method thereof, can be used for drought resisting, the soil moisture conservation of farm crop.
At present, preserving moisture of land for growing field crops mainly finished by intertillage, also do not have a kind of medicine that can water-absorbing-retaining, is used for making the soil to preserve moisture.
The objective of the invention is to invent a kind of water-absorbing water-retaining agent and production method thereof, be used for drought resisting, the soil moisture conservation of farm crop, the water saving effect is arranged, also can be used for hotel, restaurant, family planting flowers preserves moisture, reduce the number of times that waters, save the labour, also can be used as water-retaining agent, humextant is used for medical treatment, physiological articles, daily necessities.
Purpose of the present invention can reach by following embodiment:
Batching of the present invention has vinylformic acid, ammoniacal liquor, oxychlorination sodium, persulfuric acid zinc, and it is shaped as granular crystal.
The proportioning of production method of the present invention is: two olefin(e) acid 7.35--10kg, ammoniacal liquor 2.88--11kg, oxychlorination sodium 0.5--4.7kg, persulfuric acid zinc 5.18--9.18kg.
The technical process of production method of the present invention is: the Fu reaction of selecting materials → be mixed → react, and temperature remains between 35--50 ℃ during reaction, and time 30--50 divides kind → discharging → one-tenth dress.
Advantage of the present invention is: design science, selected material, reasonable ratio, production technique is simple, the product that uses the present invention to make can be used for drought resisting, the soil moisture conservation of farm crop, plants trees, plants, sows, and also can be used for hotel, restaurant, family planting flowers, reduce the number of times that waters, also can be used as water-retaining agent, humextant is used for medical treatment, physiological articles, daily necessities is a kind of ideal water absorption Humectant.
Be several embodiment of the proportioning of production method of the present invention below:
1, vinylformic acid 10kg, ammoniacal liquor 7.75kg, oxychlorination sodium 0.05kg, persulfuric acid zinc 9.18kg.
2, vinylformic acid 10kg, ammoniacal liquor 11kg, oxychlorination sodium 0.05kg, persulfuric acid zinc 6.67kg.
3, vinylformic acid 7.35kg, ammoniacal liquor 2.88kg, oxychlorination sodium 4.04kg, persulfuric acid zinc 5.84kg.
4, vinylformic acid 7.35kg, ammoniacal liquor 2.88kg, oxychlorination sodium 4.7kg, persulfuric acid zinc 5.18kg.
With mass production water-absorbing water-retaining agent of the present invention, can increase each component content as need by said ratio.
