Abstract

A multifunctional high bibulous gel is composed by acroleic acid, acroleic acid amine, plant amylum, bentonite, two kinds or more cross linkers, two kinds or more of ignition primers, stabilizers, antioxygen and self-initiated heating agents to form a water retention agent for agriculture, forestry, industry, or to be used for delivering perfume, cultivating flowers and so on. It features: making use of the self-initiated heating agent and proper batch formula. The product is composed rapidly at full manual labor or can be mass produced.

Description

But utilize the compound method and the technology of the multi-functional water absorbent gel body of manual suitability for industrialized production

Technical field:

The invention belongs to the new process of production technical field of functional high-polymer water-absorbing material in the Chemicals, be specifically related to a kind of synthetic method of high-absorbent material, but be a kind of compound method and technology of utilizing the multi-functional water absorbent gel body of craft suitability for industrialized production.

Background technology:

In the technology of the multi-functional macromolecule water absorbent material of existing production, particularly during suitability for industrialized production, all to drop into large quantities of funds and purchase relevant device, prepare High hydrophilous resin as the radiation method that the patent No. 02114782.5 is introduced, this method just must be acquired relevant device with huge fund and just can be produced in batches, investment is big, and the risk of generation is also big; Other technologies also need equipment such as heating cooling pan with dissection, reactor, and when utilizing these technology to produce, the polymeric time all needs several hrs, wastes time and energy; Some technology also needs logical nitrogen, requires polymerization or the like under particular environment, and technology is very complicated, and it is very high that production cost is increased virtually, and product does not have competitive edge when putting on market.

Summary of the invention:

The objective of the invention is to overcome the prior art defective and a kind of logical nitrogen that do not need is provided, do not need special mixing plant, the cold and hot pot of heating that does not need interlayer, do not need reactor, full open model realizes the polymerization melon at normal temperatures, but utilizes the compound method and the technology of the multi-functional water absorbent gel body of manual suitability for industrialized production.Utilize the multi-functional high-absorbent material of this explained hereafter, mainly adjust composition of raw materials, in one hour, can produce the fine high-absorbent material, technology is very simple, only utilize some household implements just can carry out suitability for industrialized production, thereby make production cost very low, allow this high product innovation popularize widely on the every field of agricultural, forestry and use.

The object of the present invention is achieved like this:

1, formulation weight ratio:

(1), vinylformic acid 10～60% (7) second linking agents 0.001～0.8%

(2) acrylamide 5～40% (8) first initiators 0.001～0.5%

(3) plant amylum 5～50% (9) second initiators 0.001～0.5%

(4) wilkinite 5～50% (10) causes termite 0.001～0.5% certainly

(5) alkali lye 15～60% (11) stablizers 0.001～0.5%

(6) first linking agents 0.001～0.8% (12) water 20～60%

Above-mentioned used plant amylum uses corn, cassava wheat, potato etc.; Alkali lye uses potassium hydroxide, sodium hydroxide to wait and prepare; The one the second linking agents use glycerine, ethylene glycol, polyoxyethylene glycol, maleinamide, methacrylate, two Asia bright alkene acyl ammonia etc.; The one the second initiators use lauroyl peroxide, Benzoyl Peroxide, Potassium Persulphate, persulfuric acid zinc, ammonium persulphate, azobisisobutyronitrile etc.;

2, production technique:

Earlier with 10～60% vinylformic acid, 5～40% acrylamides, 5～50% wilkinite, 5～50% plant amylums and 20～60% water mix in acidproof rotten container, add 15～60% alkali lye then, then add 0.002～1.6% the one the second linking agents successively, 0.0002～1% the termite of initiation certainly, after stirring, be placed into long 5～5400cm, wide 2～200mm, the Stainless Steel Disc of dark 0.5～30cm or vinyl disc are by its heated polymerizable voluntarily, after half hour, become resilient gelinite, after from basin (dish), taking and wait its cooling off, broken by building, the existing product of weighing and bagging (also can after drying, pulverize weighing and bagging again).

Claims

But 1, a kind of compound method and technology of utilizing the multi-functional water absorbent gel body of craft suitability for industrialized production, its characteristic formula following (by weight percentage):
