A kind of method that oil-soluble etherified amino resins prepare capsule

The present invention provides one kind using oil-soluble alkanol etherified amino resins as wall forming monomers, the method that capsule is prepared in situ, the following steps are included: 1) amino resins of the alkanol etherificate with different carbon chain lengths is blended with oil soluble material, and dissolution is sufficiently stirred and obtains uniform oily phase；2) the uniform oil of preparation is added in the aqueous solution containing emulsifier, carries out that emulsification pretreatment is sufficiently stirred, obtain particle size range in the emulsion droplet of 10nm~5mm；3) emulsion procedure is heated up, and adjusting pH value makes etherified amino resins that polymerization curing reaction occur on emulsion droplet surface, the cyst wall for forming the oily phase of package obtains the capsule with core-shell structure after being filtered, washed.The invention synthesis technology is simple, and consume energy low, low for equipment requirements, easy control of reaction conditions, the prospect with large-scale production.This easy encapsulation process has very vast application prospect in pesticide field, cosmetic field, Intelligent heat storage temperature-regulation fabric field.
