Therefore, defects in the prior that the safety of a conventional phosphorus source is not enough and the economic cost is too high are solved.
Description
Technical field
The present invention relates to a kind of composite, relate in particular to a kind of benefit phosphorus composite material and preparation method thereof.
Background technology
Phosphorus is one of more mineral element of animal body intensive amount, and its requirement is only second to calcium, occupies critical role in growth of animal, growth.The phosphorus that wherein occupies total phosphorus 85 ~ 88% is present in bone and the tooth, keeps the normal consistency of bone and tooth with calcium.And phosphorus is also as the component of energy-rich phosphate bond and phosphocreatine, participate in the energetic supersession of body, phosphorus participates in the absorption of lipid material, liposoluble vitamin and the formation of cell membrane in the mode of phosphatide, and as the constituent of inhereditary material and some enzymes, participate in the many important life process of body.Phosphorus shortage or deficiency can cause growth of animal slowly and stagnation in the grain ration, and osteopathy occurs, and cause the serious consequences such as death when serious.
The phytase of shortage Hydrolysis of Phytic Acid is lower to the utilization rate of phosphorus in the plant feed in the nonruminant such as pig and bird and the fish digestive tube, must satisfy by adding the phosphorus source needs of livestock and poultry phosphorus.Phosphorus source commonly used in the feed comprises bone meal and phosphoric acid salt.Bone meal is that the bone of animal processes, in feed, be used as calcium, the use of phosphorus fill-in, but because composition changes greatly, it is unstable to originate, and foreign odor often arranged, the Animal Bone purchaser who more has is because avoiding the fly maggot breeding, often sprays some medicaments and causes bone meal band poison, think on the feed industry that abroad the bone meal class is to cause the immediate cause of rabid ox disease, so its use amount reduces gradually.Phosphoric acid salt mainly comprises calcium dihydrogen phosphate, calcium monohydrogen phosphate, tricalcium phosphate.
Bentonite is the clay rock take montmorillonite (Montmorillonite) as essential mineral.Montmorillonite is a kind of moisture layer aluminosilicate mineral, forms by aluminium of two silicon-oxy tetrahedron therebetween (magnesium) oxygen (hydrogen-oxygen) are octahedra, belongs to the three-layer clay mineral of 2:1 type.Lattice spacing is from being 0.96 ~ 2.14nm, and these nanoscale twins are reunited together, forms the clay particle that the hundreds of nanometer arrives several microns.
Summary of the invention:
The technical problem to be solved in the present invention is: in the prior art, phosphorus source security commonly used is inadequate, and financial cost is too high.
For addressing this problem, the technical solution adopted in the present invention is:
The invention provides the agent of a kind of benefit phosphorus, load has the composite of P elements in the bentonite that this benefit phosphorus agent is modification.
The present invention also provides the preparation method of a kind of above-mentioned benefit phosphorus agent, and step is:
(1) sulfuric acid or hydrochloric acid solution are joined in the bentonite slurry, fully stir, make mud, use again the steam digestion, and carry out batch type, after the steam digestion, wash to pH be 4 ~ 5, concentrated, filter, dry and pulverize;
As preferably: the bentonite slurry particle diameter is 60 orders ~ 100 orders, and water content is 10 ~ 15%;
As preferably: sulfuric acid or hydrochloric acid solution mass fraction are 25% ~ 35%;
As preferably: the digestion time of steam digestion is 5 ~ 6h, stirs once every 15 minutes therebetween;
(2) powdery product that makes is mixed with dry quick lime powder, drip entry while stir again, stir into pasty state, place thermostatic drying chamber fully to react, washing, oven dry is milled;
As preferably, the weight of the water that is added dropwise to is powdery product and dry calcium lime powder mixture total weight amount 2 ~ 2.5 times;
(3) product that obtains of will milling joins in the orthophosphate solution, stir fully, and precipitation and separation, oven dry is milled;
As preferably, orthophosphate solution concentration is 5 ~ 10mol/L;
As preferably, product and the orthophosphate solution solid-liquid mass ratio that obtains of milling is 1:100 ~ 1:500.
Mend the phosphorus agent as the benefit phosphorus feed addictive of livestock and poultry, aquatic livestock, cattle and sheep.
The invention has the beneficial effects as follows:
(1) as the huge mineral of a kind of reserves, the bentonite production cost is lower, and implementation method is easy, and to human body and environment, is safe from harm and pollutes.
(2) the benefit phosphorus agent take bentonite as carrier is easy to mix with feed, forms Uniform Dispersion system, and is easy to use.
(3) bentonite pulvis, because having lamellar structure and heterogeneity distribution of charges, the toxin of the virus in the alimentary canal, germ and generation thereof, gas etc. there are extremely strong fixing, inhibitory action, make it lose pathogenic effects, when releasing phosphorus, also have the effect of absorbing toxin; In addition alimentary canal mucous membrane is also had very strong covering protection ability, repair, improve Mucosa Barrier to the defense function of attack factor, have balance normal flora and local analgesic effect.
