Summary: ?MEKO) of  of Yi of  eyebrow Zi and IPDI3 get together body reacts and graft gets together aether of glycol simple nail (MPEG) preparation close model agent of solidify of ester of cyanic acid of much surprise of ability in swimming, the structure that uses infra-red spectrometer, heat to broke the equipment such as quality appearance and transmission report lens to study this solidify agent, solution seals temperature and glue bundle configuration, inspected solidify agent to reach its to mix the stability of keep in storage of the latex to effect of solidify of resinous of polyurethane of hydroxyl ability in swimming at the same time. The result makes clear, the solution of agent of solidify of this ability in swimming seals temperature to be between 249 ℃ of 95 ~ , optimal use temperature controls agent of; this solidify to be able to improve polyurethane of hydroxyl ability in swimming apparently in 160 ℃ of film be able to bear or endure water, be able to bear or endure solvent and mechanical function, additional of solidify agent and polyurethane of ability in swimming mix a latex to have stability of good keep in storage in all.

Preparation of resinous of ability in swimming uses adscititious emulsifying agent more or offer from the means of emulsification kiss water radical group to dissolve mediumly in order to solve colophony in water photograph problem, the existence that kisses water radical group and the existence after cannot offerring more cross-linking structures to cause colophony of ability in swimming to become film is able to bear or endure the problem such as difference of water, solvent resistance. Be aimed at afore-mentioned problems, people is before construction of colophony of ability in swimming temporarily adscititious solidify agent, this kind of method can improve integral performance of resinous of ability in swimming substantially, but construction measure increases to bring about product stability easily to drop, make exhaustless colophony cannot be deposited for a long time at the same time, easy create waste, because this researcher devotes oneself to odd constituent again,study from resinous of cross-linking ability in swimming. Of article preparation close model agent of solidify of ester of cyanic acid of much surprise of ability in swimming can be stabilized below normal temperature as concomitant as the colophony of ability in swimming that contains active hydrogen, but after becoming film solution of be heated process is sealed, the —NCO that releases a dissociate base the group participates in cross-linking to react, have the stability of keep in storage, characteristic that becomes film from cross-linking.
