Abstract
A P-complementing forage additive containing the controlled slow releasing P is an active P contained bimetal oxide prepared from phosphate or hydrogen phosphate through calcining hydrotalcite to obtain bimetal oxide, adsorption, ionic exchange reaction, filtering, drying and pulverizing.
Description
Technical field
The present invention relates to a kind of agent of benefit phosphorus and preparation method and purposes of controlled release type phosphorus.
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 accounts for 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, participate in the many important life process of body as the constituent of inhereditary material and some enzymes.Phosphorus shortage or deficiency can cause the slow or stagnation of growth of animal in the daily ration, and osteopathy takes place, and cause serious consequences such as death when serious.
Lack the phytase of hydrolysis phytic acid in nonruminant such as pig and bird and the fish alimentary canal, lower to the utilization rate of phosphorus in the plant feed, must be by adding the needs that livestock and poultry phosphorus is satisfied in the phosphorus source.Phosphorus source commonly used in the feed comprises bone meal and phosphoric acid salt.Bone meal is that the bone by animal processes, in feed, be used as calcium, the use of phosphorus fill-in, but because of composition changes greatly, the source is unstable, and foreign odor often arranged, the animal bone purchaser who more has is because of 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 etc.The biological value in phosphorus source not only influences the culturing economic benefit, and can not will be excreted with ight soil by the phosphorus that animal absorbs, and causes the pollution to environment of phosphor resource waste and phosphorus.
Bimetallic oxide is a kind of synthetic material who is made up of the metal oxide of two kinds of different valence state, is called for short LDO (Layered Double Oxides).It has the shepardite of being similar to (Mg (OH)

Hydrotalcite will destroy its layer structure 450 ℃～550 ℃ following calcinings, the bimetallic oxide that obtains mixing (LDO).Bimetallic oxide can come the restoration and reconstruction hydrotalcite structure by anion and the hydrone in the absorption environment, and because of having bigger specific area and pore volume, acceptant object.Bimetallic oxide after the roasting has bigger specific area than its predecessor, and has structure " memory " effect, promptly reuptakes anion and make it recover original layer structure in water environment.
Summary of the invention
The agent of benefit phosphorus and preparation method and the purposes that the purpose of this invention is to provide a kind of controlled release type phosphorus.
The benefit phosphorus agent of controlled release type phosphorus is a kind of bimetallic oxide that contains active phosphorus, and by weight percentage, the content of phosphorus in bimetallic oxide is 5～30%.
Preparation method's step of the benefit phosphorus agent of controlled release type phosphorus is as follows:
1) with hydrotalcite at 450～550 ℃ of temperature lower calcinations, make bimetallic oxide, be ground to again greater than 400 orders, add water and stir, make concentration and be 1%～10% suspension slurry;
2) be the phosphate of bimetallic oxide weight 6～35% with phosphorus content, be pre-configured to the aqueous phosphatic of 0.1～1.0mol/L, slowly add in the suspension slurry of step 1) room temperature reaction 5～10 hours down in stirring;
3) the centrifugal or filtering means dehydration of suspension slurry step 2);
4) filter cake of step 3) gained is dried, is crushed to greater than 300 orders, obtain the benefit phosphorus agent of controlled release type phosphorus
The hydrotalcite that uses in the invention can be the commercial goods, also can be according to prior art for preparing, and its technology of preparing is well-known.The hydrotalcite chemical structure of general formula is: [M
