c：1 ~ 3 part of persulfate is dissolved with 10 ~ 20 parts of water, stirring makes it complete molten；
d：To adding remaining water in reactor, polyvinyl alcohol, emulsifying agent, sodium acid carbonate are added under agitation, be heated to 70 ~ 75 DEG C and stir always to solids it is complete it is molten after, add the vinyl acetate and dibutyl maleate mix monomer of 1/2 amount, the persulfate solution for adding step b to prepare after 15 ~ 20min of stirring；
e：After temperature in reactor is promoted into 80 ~ 85 DEG C, the vinyl acetate and dibutyl maleate mix monomer of remaining 1/2 amount are homogeneously added into 6.5 ~ 7.5h, the persulfate solution of step c preparations is finally added, continue to stir 3.5 ~ 4.5h, stop heating, cooling down obtains adhesive.
Compared with prior art, its advantage is the present invention：1. the present invention is odorless, tasteless, nontoxic thermoplastic adhesive, and adhesive strength is high, non-aging；
2. invention adhesive is with water as dispersant, therefore uses safety, dangerous without fire explosion, easy to clean；
3. the glue-line water white transparency after invention adhesive solidifies, good toughness；
4. invention adhesive is mainly used in the bonding of timber, paper, fabric, cellulose acetate, dacron membrane, film etc..
