Abstract
The invention discloses a kind of high efficiency composition water-loss reducer, by bentonite, cellulose ether, polyacrylamide, biological particles, the component mixed preparing such as starch ether is formed for the invention.High efficiency composition water-loss reducer of the invention is by science selection, it is reasonably combined, peanut shell powder, corncob powder, bamboo carbon powder with special microcellular structure are with the addition of, makes its specific surface area larger, moisture is easier to enter and is combined with hydrophilic-structure inside compound water retaining agent.The cellulose ether of addition, contains a large amount of hydrophilic hydroxy group groups in addition on starch ether its strand, and hydrophilic radical type and quantity increased in making compound water retaining agent, and foring effective three-dimensional space net structure increases, and retaining volume is increased.
Description
Technical field
The present invention relates to chemical field, and in particular to a kind of high efficiency composition water-loss reducer.
Background technology
Water conservation water-saving technology is one of core content of Agroforestry in China high-efficient water use research, during facility substrate culture is also
The important trend of state's agriculture and forestry modernization development.Therefore, the water-saving facility substrate culture of effective development be Agroforestry in China towards
The inevitable choice of Sustainable Development in Future.
Recent study shows：Water conservation water-saving result of the water-loss reducer in facility substrate culture is notable, in many countries
It is used widely.Because water-loss reducer has special physical arrangement and chemical characteristic, sole mass hundreds times can be rapidly absorbed very
To thousands of times of moisture, with special water conservation, water saving and repeatedly water imbibition the features such as.Hydrogel after water suction can slowly discharge
Moisture is utilized for plant, improves plant drought ability, is reduced irrigation advance and is become estranged the invalid evaporation of moisture.But part at this stage
The artificial synthesized macromolecule water-loss reducer p universal meta-alkalescences of H values, long-term use easily causes cultivation matrix（Peat, turf, soil
Earth）Alkalescence enhancing, and such water-loss reducer some catabolites to cultivation matrix and the toxic effect of plant, be unfavorable for plant roots
System's growth and the absorption to nutriment.Simultaneously, although macromolecule water-loss reducer can effectively water-saving fertilizer-saving, but to cultivation matrix
Physicochemical property produce negative sense influence, such as after water stickiness strengthen, easily cohered with matrix, reduction matrix permeability.Macromolecule is protected
Aqua production technology and raw material sources requirement are also higher, expensive, are limited its range of application, and this is limited to a certain extent
The popularization of class water-loss reducer.Therefore, with multi-functional compound water retaining agent research and development nontoxic and inexpensive after optimum pH, degraded
It is the important directions of Chinese water-loss reducer research and development.
The content of the invention
Present invention aim at, there is provided a kind of high efficiency composition water-loss reducer, the technical solution adopted by the present invention is as follows：
A kind of high efficiency composition water-loss reducer, it is characterised in that be mixed with by weight percentage by following components and formed：
Bentonite 20-30 parts
Cellulose ether 10-20 parts
Polyacrylamide 10-25 parts
Biological particles 10-30 parts
Starch ether 20-35 parts.
Further, described cellulose ether is according to weight by hydroxypropyl methyl cellulose ether, sodium carboxymethylcellulose
Than being 1:2 mixing compositions.
Further, the molecular weight of described polyacrylamide is in 10-20 ten thousand.
Further, described biological particles including peanut shell powder, corncob powder, bamboo carbon powder.
Further, described biological particles are according to weight ratio by peanut shell powder, corncob powder, bamboo carbon powder
It is 2:2:1 mixing composition.
The present invention is relative to the beneficial effect of prior art：High efficiency composition water-loss reducer of the invention by science selection,
It is reasonably combined, peanut shell powder, corncob powder, bamboo carbon powder with special microcellular structure are with the addition of, increase in powdered
Compound water retaining agent specific surface area, make its specific surface area larger, moisture be easier to enter compound water retaining agent inside and hydrophilic knot
Structure is combined.The addition of biological particles material reduces water loss beneficial to the rate of water absorption for accelerating compound water retaining agent, saves and irrigates
Water, improves efficiency of water application, cost-effective, is a kind of effective way that agriculture and forestry organic waste material is recycled.The fiber for adding in addition
Contain a large amount of hydrophilic hydroxy group groups on plain ether, starch ether its strand, make hydrophilic radical type and quantity in compound water retaining agent
Increased, foring effective three-dimensional space net structure increases, and retaining volume is increased.Compound water retaining agent tool of the invention
There is water-absorbing-retaining performance higher, easily mixed with matrix, certain Water absorption, Water-saving effect can be still kept after Reusability
Persistently, efficiency of water application is improved, and has certain regulation and improving effect to cultivation matrix physicochemical property and structure.
