Patent ID: 8044117

Claim:
A method for the preparation of an adhesive, comprising: a step of bonding a plurality of flocculated resin particles with one another, thereby forming a carrier; a step of forming a core member made up by the carrier and a curing agent; said carrier being chemically inert to said curing agent and having a gap in its inner structure, said curing agent made up by one or both of a metal chelate which is liquid at ambient temperature and a metal alcoholate which is liquid at ambient temperature, said carrier is immersed in said curing agent, said curing agent intruded into said gaps within said carrier and impregnates said carrier by a capillary phenomenon and is held in said carrier by capillary action; a step of rinsing said carrier after said step of forming said core member; a step of mixing said core member and a capsule resin agent having an average particle size smaller than a particle size of said core member to deposit said capsule resin agent on a surface of said core member electrostatically; a step of electrostatically depositing a capsule resin agent on the surface of said core member by mixing said core member and said capsule resin agent having an average particle size smaller than said particles of said core member; a step of forming a latent curing agent by stirring and fusing said capsule resin agent deposited on said core member to form a capsule covering said surface of said core member; and a step of manufacturing the adhesive by mixing and stirring said latent curing agent manufactured by said above process, a thermosetting resin, and a silane coupling agent.
