It is an object of the invention to provide a kind of degradable polyurethane foam chemical fertilizer and preparation method thereof, synthesis has low-density
Foam carrier and low content konjaku flour, the urea of dissolution rate high.Have processing technology simple simultaneously, production efficiency is high.It is logical
Control polyurethane foam density and konjaku flour are crossed, hence it is evident that the release of control urea, while konjaku flour can obvious degradation polyurethane
Foam, preparation method is simply easily implemented.
Degradable polyurethane foam chemical fertilizer of the present invention, each component is made according to following parts by weight：
Component A：
B component
Konjaku flour and urea
C components
Water.
PPG DEP-505S is 3 degrees of functionality, the PPG of molecular weight 3300.
PPG EDE-28 is 2 degrees of functionality, the PPG of molecular weight 4000.
Foam stabiliser is foam stabiliser L-580.
The preparation method of described degradable polyurethane foam chemical fertilizer is more by component A PPG DEP-505S, polyethers
First alcohol DED-28, foam stabiliser, crosslinking agent, isocyanates TDI-80, the NCO content of system is 3~5 one-component performed polymer.
In preparation process, 100 parts of component A is taken, 15-30 parts of B component konjaku flour, urea 25-50 parts, 0.5 part of C components water,
Three component material mix high-speed stirred, and foaming obtains degradable polyurethane foam chemical fertilizer；
Wherein, component A, B component, the mass ratio of C components are 100:40-80:0.5.
The manufacturer of PPG DEP-505S is the federal chemistry Industrial Co., Ltd of Zibo moral letter, with this kind of polynary
The suction moisture retention of the polyurethane foam that alcohol does is strong.
The manufacturer of PPG EDE-28 is the federal chemistry Industrial Co., Ltd of Zibo moral letter, uses this kind of polyalcohol
The polyurethane foam done keep it is highly hygroscopic on the basis of can also enhanced article toughness.
The manufacturer of foam stabiliser L-580 be step figure new high-tech material (China) Co., Ltd, with stable foam with
Regulation abscess, emulsifies the effect of foam material.
Crosslinking agent ethylene glycol plays a part of chain extender simultaneously in the present invention, and the strand in reaction is further expanded
Greatly, the pliability of product is increased.
By controlling polyurethane foam density and konjaku flour, the release of urea can be substantially controlled, while konjaku flour can be bright
Aobvious degradable polyurethane foam.
Compared with prior art, the invention has the advantages that：
The konjaku flour of foam carrier and low content of the present invention synthesis with low-density, the urea of dissolution rate high.Have simultaneously
There is processing technology simple, production efficiency is high.By controlling polyurethane foam density and konjaku flour, hence it is evident that control releasing for urea
Put, at the same konjaku flour can obvious degradation polyurethane foam, preparation method simply easily implemented.
