Abstract
The invention belongs to the technical field of the fertilizer production, and relates to a degradable resin envelop slow-control fertilizer-releasing production process. Tung oil, urea resin, thermoplastic resin, thermosetting resin, polyacrylamide, modified starch and polyvinyl alcohol are reasonably processed into an envelope material; and urea, composite fertilizer and granular potassic fertilizer are used as granulation base stock. The production method is simple in process, the polymer resin material which can be completely and biologically degraded is elaborately selected as the envelope material to envelope the granular urea or the granular composite fertilizer, the special polymer envelop can intelligent control the release of nutrients according to the temperature of soil and the requirement of crops so as to improve the utilization rate of the fertilizer, the envelop shell which is remained in the soil can be completely degraded after the nutrients are completely released, no harm on the environment exists, and the environment-friendly fertilizer can be obtained.
Description
Technical field
The invention belongs to the fertilizer production technology field, relate to a kind of degradable resin coating slow-release or control-release fertilizer production technique.
Background technology
Soil fertilizer is two big fundamentals of agriculture production.From the eighties in last century, China can plough the soil and use chemical fertilizer in a large number, cause that land deterioration, soil compaction, soil fertility decline, organic matter and beneficial microorganism reduce, agricultural ecological is unbalance, deterioration in quality, water resources and environment like pollution in various degree, makes human health like potential threat.Research, development of new, nuisanceless, degradable fertilizer are vast agricultural sciences worker's important topics.Biochemical fertilizer has become a kind of important organic fertilizer.Existing coating slow-release or control-release fertilizer is because there are following two kinds of phenomenons in the defective of coated fertilizer: when 1) adopting water-soluble stronger coated fertilizer, the chemical fertilizer granule dissolving is very fast, and the fertilizer efficiency short period of time discharges, and is unfavorable to the operation growth; When 2) adopting water-soluble strong poor coated fertilizers such as sulphur, though can prolong the time of releasing of fertilizer efficiency, sulphur decomposes slower in soil, and the degraded several years time to decades of needs is bigger to the harm of environment and soil fully.
Summary of the invention
The object of the present invention is to provide simple, the easy-operating degradable resin coating of a kind of technology slow-release or control-release fertilizer production technique, for the production of fertilizer efficiency slowly discharge, the coated fertilizer degradable fertilizer, avoid the coated fertilizer residue to the pollution of environment.
For achieving the above object, the present invention adopts following technical scheme:
Degradable resin coating slow-release or control-release fertilizer production technique of the present invention is characterized in that production stage is as follows:
A) preparation of coated fertilizer; Be warmed to 50-65 ℃ in the tung oil adding reactor with the 30-50 weight part, when stirring, add following substances in parts by weight successively, the insoluble type urea-formaldehyde resin of cold water 50-65 part, vinylformic acid thermoplastic resin 5-15 part, thermosetting phenolic resin 5-15 part, poly-propionic acid amide 3-5 part, 5 parts of treated starches, 5 parts of polyvinyl alcohol; After stirring, be warmed to 90-95 ℃, continue to stir 30-40 minute, reduce the temperature to 40-50 ℃, add the n-butyl acetate of 10-40 weight part again, namely obtain described coated fertilizer;
B) granulation; The granulation base-material is heated to 50-60 ℃, sends into the tablets press granulation;
C) particle coating; The particle that tablets press is formed enters dryer; 80-95 ℃ of baker temperature; dry to water content 1-2%; particle after will drying is then sent into coating machine, and the control temperature is to 50-80 ℃; spray into steps A) described coated fertilizer; the coated fertilizer consumption is the 2%-3% that treats coated granule weight, after the cooling, namely obtains described degradable resin coating slow-release or control-release fertilizer through the screening metering packing.
The insoluble type urea-formaldehyde resin of above-mentioned cold water is the mixture of 4 methylene radical, 5 nitrogen of 3 methylene radical, 4 nitrogen of parts by weight 40-50% and 50-60%.
This production method technology is simple, the macromolecule resin material of meticulously preferred totally biodegradable is as coated fertilizer, granular urea or granular compound fertilizer are carried out coating, distinctive polymer capsule can need the intelligent control nutrient to discharge with the soil moisture and crop, thereby raising utilization rate of fertilizer, the involucrum that nutrient remains in the soil after discharging fully can be degraded again fully, can not cause any infringement to environment, is a kind of environmental friendly fertilizer.
