Abstract
The invention relates to a compound fertilizer granulating agent and a preparation method thereof. The compound fertilizer granulating agent comprises the following components in percentage by mass: 40 to 60 percent of molasses, 5 to 20 percent of polyvinyl alcohol formaldehyde condensation compound solution, 10 to 15 percent of lignosulfonate and the balance of water. The preparation method comprises the following steps of: dissolving lignosulfonate in water, and stirring uniformly; and adding the polyvinyl alcohol formaldehyde condensation compound solution into the solution, adding the molasses into the mixed solution, and stirring uniformly to obtain the compound fertilizer granulating agent. The compound fertilizer granulating agent is in the liquid state at the normal temperature and is water-soluble, can be added into fertilizer slurry directly without being heated in the using process, and is easy to operate and small in used amount; rounded fertilizer granules can be prepared only by 2 to 5 kilograms/ton of fertilizers without influencing the total nutrients of fertilizers, and high-concentration compound fertilizers are easy to produce; and the fertilizer granules have high strength, so that the fertilizers are difficult to pulverize and agglomerate in the processes of production, transportation and storage, and the quality of the fertilizers is ensured.
Description
Technical field
The present invention relates to a kind of compound fertilizer granulating agent and preparation method thereof.
Background technology
Composite fertilizer refers to have at least two breedings to divide the fertilizer of only being made by chemical process of the amount of showing in nitrogen, phosphorus, three kinds of nutrients of potassium, is a kind of of composite fertilizer.The advantages such as composite fertilizer has the nutrient content height, minor component is few and physical behavior is good for balance fertilizing, improve utilization rate of fertilizer, promote the stable high yield of crop that very important effect is arranged.
The solid composite fertilizer overwhelming majority that countries in the world and China produce is granulated fertilizer, and granulated fertilizer has following advantage aspect physicals: 1. specific surface area is little, reduces the possibility of caking.2. have good flowability, be convenient to mechanized handling and fertilising.3. bulk density is little, relative reduce packing, store or trucking costs.4. the dissolution rate of granulated fertilizer in soil is slower, can alleviate or eliminate the injury to crop root, and the leaching that also can reduce the nitrogen nutrient simultaneously runs off.
For composite fertilizer, if want to cause the round shaped grain shape must add binding agent.The most frequently used binding agent has: clay class (comprising clay, chalk soil, kaolin etc.), phosphogypsum, fused(calcium magnesium)phosphate etc.Adopt above-mentioned binding agent can have some shortcomings:
1. cohesive force is not strong, and the fertiliser granulates intensity of producing is low, and fertilizer is easy disintegrating in the production and transport process, and efflorescence causes fertilizer agglomeration, and poor fluidity is not easy to mechanized handling and fertilising.
2. useless composition adds manyly, and the effective constituent of fertilizer is lower.If adopt above binding agent just to be difficult to produce high-concentration compound fertilizer, yet high density is a megatrend of current composite fertilizer industry development; High density is not only Chemical Mixed Fertilizer, and is the direction of the whole fertilizer industry development in the world.High concentration fertilizer has the advantage that unit nutrient cost, transportation and cost of marketing are lower than low-analysis fertilizer.
For above-mentioned variety of problems, developing new compound fertilizer granulating binding agent becomes the task of top priority.
Summary of the invention
The object of the invention is to overcome the deficiency of existing inorganic granulating agent, a kind of compound fertilizer granulating agent and preparation method thereof is provided, be liquid and entirely water-soluble under this compound fertilizer granulating agent normal temperature, good fluidity, in use, need not heating can directly add in the fertilizer slurry, simple to operate, consumption is little, only needs 2-5 kg/tonne of fertilizer just can produce mellow and full fertilizer particle, substantially can not affect the fertilizer total nutrient, so easier one-tenth produces high-concentration compound fertilizer, it is high to produce fertiliser granulates intensity, makes fertilizer produce transportation, deposit in the process, be difficult for efflorescence, prevent to a certain extent fertilizer agglomeration, thereby guarantee the quality of fertilizer.
For achieving the above object, a kind of compound fertilizer granulating agent provided by the invention, each component is by mass percentage, it is characterized in that: molasses 40-60%, polyvinyl alcohol and formol condensed substance solution 5-20%, sulfonated lignin 10-15%, surplus is water, and each component sum is 100%.
Described molasses are the cane sugar factory molasses.
Described polyvinyl alcohol and formol condensed substance solution is that mass concentration is that polyvinyl formal solution or the commercially available mass concentration of 5-10% is 801 glue of 5-10%, and 801 glue also claim polyvinyl formal solution.
Described sulfonated lignin are calcium lignin sulphonate.
The preparation method of a kind of compound fertilizer granulating agent of the present invention, its preparation process is:
1, calcium lignin sulphonate is water-soluble, stir, obtain solution A;
2, polyvinyl alcohol and formol condensed substance solution is joined in the solution A, stirring obtains solution B;
3, molasses are joined in the solution B, stir, obtain compound fertilizer granulating agent.
The advantage of the existing granulating agent of the present invention:
(1) this granulating agent is for entirely water-soluble, and is easy to use.
(2) cohesiveness is strong.
(3) consumption is little, produces 1 ton of fertilizer, only needs to add 2-5 kilogram compound fertilizer granulating agent, does not affect the total nutrient of fertilizer.
(4) be applicable to multiple granulation mode, such as rotary drum and granulating disc.
(5) the fertiliser granulates intensity of producing is high, average anti-crushing pressure 20-40N.
