Abstract
A slow-release fertilizer coated with urea-formaldehyde resin is prepared from the following raw materials by weight: 5-7 parts of egg shells, 8-10 parts of sheep manure, 7-9 parts of sawdust, 16-20 parts of rice washing water, 12-15 parts of tofukasu, 11-13 parts of wheat bran, 9-13 parts of lotus pond mud, 2-3 parts of biological fermentation inocula, 10-12 parts of dolomite, 6-7 parts of ammonium sulfate, 8-10 parts of sodium hydrogen carbonate, 6-8 parts of potassium chloride, 9-10 parts of magnesium phosphate, 4-5 parts of copper sulphate, 2-4 parts of potassium oxide, 6-7 parts of urea-formaldehyde resin, 1-2 parts of ethanol, 0.5-1 part of acetone, 2-3 parts of alpha-alkenyl sodium sulfonate, 5-6 parts of additives, and a proper amount of water. The slow-release fertilizer of the invention realizes stepwise release of chemical components by an approach of resin degradation, maximizes nutrition utilization, reduces the application amount of topdressing, and decreases environment burden. Meanwhile, organic materials are derived from waste organic matter in life, and the recycle of the organic materials means great contribution in various industries and fields.
Description
Technical field
The present invention is slow release fertilizer of a kind of urea-formaldehyde resin bag quilt and preparation method thereof, belongs to the Technology field of slow release fertilizer in fertilizer.
Background technology
The polymkeric substance that urea and formaldehyde reaction obtain, also known as urea-formaldehyde resin.English abbreviation UF, occurs crosslinked during machine-shaping, goods are insoluble not molten thermosetting resin.Urea-formaldehyde resin color after solidification is more shallow than resol, and be translucent shape, weak acid resistant, weak base, good insulation preformance, and wear resistance is splendid, low price, but chance strong acid, highly basic easily decompose, and weathering resistance is poor.
Urea-formaldehyde resin is generally water soluble resin, more easily solidifies, and the non-toxic after solidification, colourless, photostabilization good, life-time service nondiscoloration, also nondiscoloration during thermoforming, can add various tinting material to prepare the goods of various lovely luster.
Urea-formaldehyde resin is hard, scratch resistant, the media such as weak acid resistant weak base and grease, and low price, has certain toughness, but it be easy to water suction, thus water tolerance and electrical property poor, thermotolerance is not high yet.
As the linking agent of emulsion sizing agent, with the OH cross-linking reaction in polyvinyl acetate emulsion, water tolerance and thermotolerance can be improved.Urea-formaldehyde resin molecule-CH
2oH and NH
2can with acrylic acid modified emulsion molecule--COOH carries out condensation cross-linking to a certain extent, decreases hydrophilic radical, and water tolerance is improved, and freezing tolerance also strengthens.
Can be used for water tolerance and the less demanding goods of dielectric properties, as wiring board, switch, machine handle, meter case, knob, daily necessities, ornament, mah-jong pieces, chamber pot lid, also can be used for the manufacture of part tableware, the main application of urea-formaldehyde resin is used as wood adhesive, accounts for more than 80% of urea-formaldehyde resin total amount.
