Abstract
Disclosed is an oily anti-blocking agent. The oily anti-blocking agent is prepared from, by mass, 40-60 wt% of palm oil, 20-40 wt% of oleic acid, 5-20 wt% of oleamide, 5-20 wt% of phosphate, and 2-10 wt% of potassium stearate; a preparation method of the oily anti-blocking agent comprises the steps of heating the raw materials to 80-110 DEG C, mixing and uniformly stirring the raw materials, and cooling the raw materials to an indoor temperature; an application method of the oily anti-blocking agent comprises the steps of heating the oily anti-blocking agent to 70-110 DEG C, dropping the oily anti-blocking agent to a compound fertilizer with the temperature of 50-60 DEG C after the oily anti-blocking agent is melted, fully wrapping the oily anti-blocking agent into particle surface of the fertilizer through a wrap machine, wherein 0.5-2.0 kg of the oily anti-blocking agent is added into per ton of the compound fertilizer. According to the preparation of oily anti-blocking agent and the application method, operation is simple, industrialized production is easy, use amount is small, and cost is low; meanwhile, the oily anti-blocking agent is easy to degrade, free of pollution, good in anti-blocking effect, and is capable of making an anti-blocking rate of granulous nitro-compound fertilizer reach 90% or above.
Description
Technical field
The invention belongs to technical field of fertilizer, more particularly to a kind of anticaking agent of nitro-compound fertilizer.
Background technology
At present, mechanization of agriculture fertilising is gradually gained popularity, and the demand of compound fertilizer is increasing.However, nitro is compound
Fertilizer is the chemical fertilizer for most easily luming, because the ammonium nitrate in raw material has polycrystallinity, thus produces hygroscopicity and caking capacity is seriously limited
Its application and development is made.
In order to solve this problem, anticaking agent during most of compound fertilizer's manufacturer productions, can be all used, what is presently, there are is anti-
Agglomeration agent can be summarized as following five kinds：
(1) inert powder is the anticaking agent for using earliest, by mechanical isolation and absorption chemical fertilizer surface moisture, so as to reality
Existing preventing blocking effect, but, if be used alone, not only consumption is big, and dust is more, and for the compound fertilizer of easy caking, anti-caking
Block effect is bad；
(2) inorganic salts have preventing blocking effect because of its water absorption, but substantially reduce can the moisture absorption point of compound fertilizer；
(3) surfactant-based anticaking agent, by reducing surface tension, it is alkanamine to change the main components such as crystal habit
Cationoid, compound nitrogen slow release agent and paraffin and anions and canons surfactant mixing anticaking agent, are processed high-nitrogen slow released
The surfactant such as fertilizer, such as 18-amine., paraffin, the drawbacks of there is also certain, for example, though after 18-amine. certain hour
Can degrade, but catabolite composition containing nitrosaminess, which is carcinogenic class material, while life-time service will also result in dirt to soil
Dye, which also limits the outlet using anticaking agent chemical fertilizer；
(4) lyophobic dust class anticaking agent, refers mainly to organic water-repelling agent, such as paraffin, polyolefin, mineral oil etc.；Which is former
Material mineral machine oil difficult degradation, and people, animals and plants are harmful to, the use of many national statute restrictions mineral machine oil in the world；
(5) water soluble polymer-surfactant compound type anticaking agent, mainly water-soluble polymer and surface activity
Agent interacts to form complex, makes polymer and the property of surfactant are mutually modified, and this anticaking agent has
The characteristics of operation has high demands, during misoperation easily causes Chemical Mixed Fertilizer, water is exceeded, produces agglomeration problems.
Although the anti-caking research of the country has made great progress, it is proposed that some caking mechanisms, preventing blocking effect
Good, applied range, stable performance excellent anticaking agent but seldom, at present using oils anticaking agent parcel handling process compared with
Many, the preventing blocking effect of machine oil-amine anticaking agent is very different, and is difficult to degraded in soil, and life-time service is caused
Soil pollution.Meanwhile, in the exploitation of anticaking agent, generally existing screening blindly, the problem for taking time and effort.
The content of the invention
It is it is an object of the invention to provide a kind of consumption is few, low cost, preventing blocking effect are good, degradable, pollution-free, be easy to
The oiliness anticaking agent of industrialized production and its preparation and application.
Mass percent wt% of oiliness anticaking agent each component of the present invention is：Petiolus Trachycarpi oil 40～60, Oleic acid 20～40,
Oleamide 5～20, phosphate ester 5～20, potassium stearate 2～10.
Described Petiolus Trachycarpi oil is 58 degree of Petiolus Trachycarpi oils, and the phosphate ester is low-corrosiveness phosphate ester LYCO-P30.
The preparation method of above-mentioned oiliness anticaking agent：Above-mentioned raw materials are heated to into 80～110 DEG C, mixing and stirring is cold
But to room temperature.
The using method of above-mentioned oiliness anticaking agent is：Add the oiliness anti-caking of 0.5～2.0kg in compound fertilizer per ton
Oiliness anticaking agent is heated to 70～110 DEG C, after thawing by agent, is dripped in 50～60 DEG C of compound fertilizer, is made to prevent by packing machine
Agglomeration agent is fully wrapped in chemical fertilizer granule surface.
The present invention is had the advantage that compared with prior art：
1st, the consumption of anticaking agent is few, low cost；
2nd, it is simple to operation, it is easy to industrialized production；
3rd, preventing blocking effect is good, can be with the anti-caking rate of granular nitro-compound fertilizer more than 90%；
4th, in addition to acting on anti-caking, also with certain slow-release function；
5th, the raw material for being used is degradable material, without any pollution.
