Abstract
The invention discloses an agricultural water-retaining agent prepared with ceramic sludge and a method thereof. The method comprises the steps of mixing acyclic acid with acrylic amide with a neutralization degree of 50-80% after ceramic sludge is dryed, smashed and screened into 80 mesh, adding toluene diisocynate and polyhydric alcohols into ice-water bath, stirring with a high speed for 3-4h, then adding a photoinitiator, conducting ultraviolet irradiation for 1h, soaking the reacted product with methyl alcohol for 4-6h, and obtaining the final product by vacuum drying and smashing. According to the agricultural water-retaining agent prepared with the ceramic sludge and the method thereof, with the waste ceramic sludge as a raw material, the agricultural water-retaining agent adopts the ultraviolet irradiation to trigger a polymerization reaction, acrylic ester and polyurethane are introduced, the agricultural water-retaining agent with an excellent water-absorbing and water-retaining performance as well as strong weather resistance, and a new path to resource utilization of ceramic sludge is provided. The method of the agricultural water-retaining agent prepared with ceramic sludge is simple in process, convenient to operate, low in cost, and simple in industrial production and has wide application prospect.
Description
Technical field
The invention belongs to macromolecular material applied technical field and in particular to a kind of utilization Ceramic Sludge preparation agricultural guarantor
Water preparation and its method.
Background technology
Water-retaining agent is a kind of super absorbent resin being widely used in the industries such as agricultural, forestry, gardening, nontoxic, its
A large amount of hydrophilic groups are contained so as to the water of even thousands of times of sole mass hundreds times can be absorbed and keep in three-dimensional net structure,
And can slowly discharge moisture, therefore there is major application it is worth at soil improvement, drought-resistant water-preserving, breeding aspect of keeping a full stand of seedings.At present, state
Inside and outside water-retaining agent product is mainly polyacrylate series and acrylamide and acrylic acid salt copolymer series, also has itself and some
Natural polymer or the polymerizate of the inorganic mineral such as grafting such as starch, cellulose, Kaolin, bentonite or crosslinking.Cui Yingde
With acrylic monomerss and polyvinyl alcohol sodium sulfonate as raw material, synthesis obtains intercrossed network type High hydrophilous resin, and it inhales distilled water times
Rate reaches 900g/g, inhales 0.9% sodium chloride solution and reaches 97g/g；Acrylic acid and maleic acid are connect by the mode that Suda radiation causes
Branch is aggregated on tapioca, and its copolymer is inhaled distilled water multiplying power and reached 2256g/g；Lin Jianming has carried out the ultra-fine illiteracy of acrylic acid copolymer
The research of de- soil, the High hydrophilous resin having obtained absorbing water for 1100 times of own wt.
Ceramic Sludge is by the mud being formed after ceramics factory's process for producing waste water, and in its waste water, main component is Anhydrite, stone
Sand, Talcum, black mud, white clay, glaze etc., therefore, sludge components are mainly silicates body refuse.Ceramic industry wastewater discharge
Greatly, the daily mud producing of common medium-sized and small enterprises, just more than 10t, seldom has recycling, typically directly discards, be used on a small quantity giving birth to
Produce building materials, cause the wasting of resources, how to be the focus studied by its recycling.
Content of the invention
For the problems referred to above, the invention provides a kind of agricultural water-loss reducer of utilization Ceramic Sludge preparation and its method, adopt
Can achieve with the agricultural water-loss reducer of simple technological means preparation of industrialization high-performance, low cost with the inventive method, and
Recycling for Ceramic Sludge provides new way.
To achieve these goals, the technical solution used in the present invention is as follows：
A kind of agricultural water-loss reducer, including following raw material：Ceramic Sludge, acrylic acid, acrylamide, sodium hydroxide, toluene two
Isocyanates, polyhydric alcohol, light trigger；
In terms of the quality of Ceramic Sludge, acrylic acid 40～200%, acrylamide 10%～20%, toluene di-isocyanate(TDI) 1
～5%, polyhydric alcohol 2～8%；
The addition of sodium hydroxide for concentration be 25% sodium hydroxide in and acrylic acid so as to degree of neutralization be 50～
80%；
The addition of light trigger be Ceramic Sludge, acrylic acid, acrylamide, sodium hydroxide, toluene di-isocyanate(TDI) and
The 0.05～0.5% of total polyol weight.
Preferably, described Ceramic Sludge has processed, for ceramics factory, the mud that ceramic wastewater obtains.
Preferably, described polyhydric alcohol is one or more of ethylene glycol, propylene glycol, glycerol.
Preferably, described light trigger is aqueouss benzophenone analog derivative.
It is further preferred that described light trigger is benzophenone sulfonic acids salt or quaternary ammonium salt.
It is further preferred that described light trigger is BP-3-sodium sulfonate or UVINUL MS 40-sodium sulfonate.
The preparation method of above-mentioned agricultural water-loss reducer, using ultraviolet radiation-initiated polymerization reaction, thus prepare pollution-free,
The strong agricultural water-loss reducer of low cost, weatherability.Comprise the following steps：
(1) after Ceramic Sludge is dried 2 hours in 110～130 DEG C of baking ovens, pulverize, cross 80 mesh sieves；
(2) take a certain amount of acrylic acid, neutralized so as to degree of neutralization is with the sodium hydroxide that concentration is 25% in ice-water bath
50～80%, add acrylamide；
(3) under rotating speed is for 200～300r/min, the Ceramic Sludge powder that step (1) is obtained is slowly added into step
(2) in the solution after, in ice-water bath, toluene di-isocyanate(TDI), polyhydric alcohol are sequentially added, logical nitrogen protection, 2000～
Stirring reaction 3～4 hours under the speed of 2500r/min；
(4) add light trigger in the solution that step (3) obtains, with rotating speed 2000-2500r/min high-speed stirred
After 0.5～1 hour, it is placed in irradiation under ultraviolet；
(5) will soak 4～6 hours through the product with methylalcohol of step (4), vacuum drying, pulverize.
Preferably, described ultraviolet irradiation wavelength is 320～400nm.
