Acrylic acid isopentyl acid esters, diisooctyl maleate carry out being mixed to get mix monomer；By remaining emulsifier and diacetone third
Acrylamide is dissolved in the deionized water of a quarter, is slowly added into above-mentioned mix monomer, is dispersed with stirring after stirring and dissolving
Pre-emulsion is made after 30 minutes；
C, remaining deionized water, buffer, remaining emulsifier 10~be warming up to after twenty minutes are added into reaction kettle
65 DEG C~70 DEG C；
D, after temperature reaches 65 DEG C~70 DEG C in reaction kettle, pre-emulsion, the first initiator solution that step b is prepared is added,
After reaction 30 minutes, the second initiator solution and (3- acryloxypropyl) trimethoxy silane that step a is prepared is added；
E, after the reaction was continued 30 minutes, being cooled to 60 DEG C, the reaction was continued 30 minutes, is then cooled to 40 DEG C, sequentially adds film forming and help
Agent, stirring are discharged after twenty minutes up to adhesive.
