Abstract
The invention discloses a fully-degradable plant oil coating material for a controlled-release fertilizer and a preparation method. The preparation method comprises steps as follows: (1), 40-70 parts of various kinds of plant oil are added into a reaction tank through a gear pump, and stirring is started and performed for 10 minutes at the rotation speed of 20 turns per minute, so that the plant oil is fully mixed; (2), after the plant oil is stabilized for 5 minutes, 10-40 parts of resin is added, and nitrogen is added to the reaction tank for 10 minutes to remove air in the reaction tank; (3), the reaction tank is heated by an electric heater, the temperature is raised for 10 hours, the reaction temperature is raised to be 100-170 DEG C, heat preservation is performed for 5 hours, then the temperature is reduced to 40-80 DEG C, and the coating material is prepared. The coating material has the benefits of capability of natural degradation and avoidance of environment pollution in the fertilization process.
Description
Technical field
The present invention relates to slow-release or control-release fertilizer technical field, particularly relate to coated fertilizer and the preparation method of a vegetable oil degradable slow-release or control-release fertilizer.
Background technology
China is Fertilizer application first big country, on the low side to the use utilization ratio of fertilizer at present, and the fertile utilization ratio of N of current China only has 20%-23%, causes most of fertilizer to form waste, causes the pollution to environment simultaneously.Be proposed slow, Controlled Release Fertilizer product according to this kind of current domestic priority of situation, effectively control the waste of fertilizer, from the production technique of slow-release or control-release fertilizer, current coated fertilizer kind is more, although can control nutrient but coated fertilizer does not reach the requirement of degradable.According to this kind of situation, our independent research, developing with vegetables oil is the degradable coated fertilizer of solvent.
Generally speaking, the technical problem needing those skilled in the art urgently to solve at present is: development can the coated fertilizer of sustained-controll-release fertiliser of degradable.
Summary of the invention
Object of the present invention is exactly that provide coated fertilizer and the preparation method of vegetables oil degradable slow-release or control-release fertilizer, it has this coated fertilizer can be degradable in nature, avoids the advantage of contaminate environment in order to solve the problem.
To achieve these goals, the present invention adopts following technical scheme:
The coated fertilizer of one vegetable oil degradable slow-release or control-release fertilizer, comprises vegetables oil, resin, containing following weight component, and vegetables oil 40-75 part; Resin 10-40 part.
Preferably, described vegetables oil is one or more mixtures in soya-bean oil, sweet oil, Viscotrol C, oleum lini, tung oil, plam oil, allspice oil, rapeseed oil, turps.
Preferably, described resin is one or more mixtures of Gum Rosin, polyvinyl chloride (PVC) RESINS, polyvinyl resin, resol, phenol type novolac epoxy, ortho-cresol type novolac epoxy, bisphenol A-type novolac epoxy, bisphenol-A epoxy vinyl ester, polyimide resin, polypropylene, polycarbonate, nylon, polyetherketone, polyethersulfone.
The coated fertilizer preparation method of one vegetable oil degradable slow-release or control-release fertilizer, is realized by following steps:
(1) join in reactive tank by 40-75 part various plants oil by toothed gear pump, open and stir, setting speed 20 revs/min, stirs 10 minutes, vegetables oil is fully mixed;
(2) after stablizing 5 minutes, add 10-40 part resin, nitrogen injection 10 minutes in reactive tank, the air in reactive tank is got rid of;
(3) with electric heater, reactive tank is heated, heat up 10 hours, temperature of reaction is upgraded to 100-170 DEG C, be incubated after 5 hours, then lower the temperature, be cooled to 40-80 DEG C and namely make this coated fertilizer.
Beneficial effect of the present invention: the coated fertilizer of this vegetables oil degradable slow-release or control-release fertilizer can be degraded naturally, avoids fertilising process to environment.
