Abstract
The present invention provides film forming agents for coating seeds, which contain refined konjak powder or the chemical modification products of refined konjak powder, and a preparation method thereof. The film forming agents are mainly composed of refined konjak powder or chemical modification products thereof, emulsifying, wetting and suspending agents, penetrating agents, colloid protecting agents, viscosity stabilizers, antifreezing agents, preservative agents, warning colors, water, etc. The film forming agents have the advantages of less dose, low cost and no pollution.
Description
The present invention relates to a kind of kind clothing membrane-forming agent that contains konjaku powder or its chemical modification product, it can be re-dubbed the kind clothing agent of various functions with Multiple Pesticides, little fertilizer and plant growth regulation etc.
Used kind clothing film forming matter mainly contains two classes at present: a kind of is cellulose sodium carboxymethyl, and another kind of is polystyrene and analogue polyvinyl acetate and polyvinyl alcohol.Because of the viscosity of cellulose sodium carboxymethyl is low, so consumption is big, the cost height, and water insoluble need of polystyrene and analogue polyvinyl acetate thereof used organic solvent, so life-time service pollutes the environment.
For this reason, the objective of the invention is to overcome the deficiency of above-mentioned prior art, and provide that a kind of consumption is few, cost is low, and the kind clothing membrane-forming agent that does not pollute the environment, this membrane-forming agent can be composite with active ingredient (as agricultural chemicals, little fertilizer etc.) as the nonactive composition of kind of clothing agent.
The technical scheme that realizes the object of the invention is the kind clothing membrane-forming agent of a kind of konjaku powder or its chemical modification product; mainly by 0.1～0.8% the konjaku powder or the chemical modification product of konjaku powder; the wetting suspension agent of 1～5% emulsification; 1～5% permeate agent; 0.1～0.5% viscosity stabilizer, 0.02～0.1% colloid protective agent, 2.5～6.5% frostproofer; 0.02～0.08% sanitas, 0.1～0.8% warning colouration and 82.74～93.72% water are formed.
Wherein the chemical modification product of konjaku powder is konjaku powder and MALEIC ANHYDRIDE or gallic acid or phosphatic reaction product.
And; emulsified wetting suspending agent is selected Sodium dodecylbenzene sulfonate or calcium dodecylbenzene sulphonate or tween for use; permeate agent is selected peregal or iso-octyl sodium sulfosuccinate for use; viscosity stabilizer is that phenol, colloid protective agent are selected dextrin or B cyclodextrin for use; frostproofer is selected ethylene glycol for use; sanitas is selected potassium sorbate or phenylformic acid for use, and warning colouration then is rhodamine B or Acid Red B.
The compound method of the kind clothing membrane-forming agent of konjaku powder or its chemical modification product is: at first that the chemical modification product of konjaku powder or konjaku powder is soluble in water, after treating abundant swelling, filter with 160～240 order nylon filter bag, gained rubber cement liquid is standby, wherein the chemical modification product of konjaku powder is to be raw material with the konjaku powder, carries out the esterification reaction product of dry method modification gained with MALEIC ANHYDRIDE or gallic acid or phosphoric acid salt; The wetting suspension agent of emulsification, permeate agent are added less water and stir, add frostproofer, sanitas, stablizer respectively and make mixing solutions; Then rubber cement liquid is added in the mixing solutions and grind mixing; Add colloid protective agent again, and measure the slip pH value, pH value is transferred to 6.2～7.2; Add the warning colouration liquid that hydration is ground at last, and the make up water ad pond om, it is ground with colloidal mill the red flowable thickness homogeneity liquid of gained is membrane-forming agent behind the mixing.
Film forming matter in provided by the invention as shown from the above technical solution kind of clothing membrane-forming agent is konjaku powder or its chemical modification product; and the main component in the konjaku powder is a Rhizoma amorphophalli glucomannan; it is the high-molecular weight natural polysaccharide; fully biodegradable; and with its membrane-forming agent made from water as solvent; do not pollute the environment; be two-dirnentional structure because of Rhizoma amorphophalli glucomannan again; has hydroxyl; wetting ability genes such as acyl group have fabulous water absorption and swelling and undissolved character and very high viscosity, so consumption is few; cost hangs down and has good film-forming properties; and konjaku powder has improved its viscosity and solvability after chemical modification, makes its film forming character and processing characteristics better.
