Step 2: the aqueous mixture of step 1 is put into autoclave, then it is passed through ethylene and displaces air in autoclave；
Step 3: material is warming up to 80 DEG C of reaction temperature by reacting kettle jacketing water and is stirred, it is implanted sequentially 100 parts of acetic acid of monomer Vinyl acetate, 18 parts of acrylic acid, 0.08 part of cumyl peroxide, 0.45 part of tert-butyl hydroperoxide, 0.9 part of sodium pyrosulfite；
Step 4: being cooled to 40 DEG C of modified EVA aqueous solutions formed below.
Since above-mentioned technical proposal is used, the present invention has following advantages and effect compared with prior art：
1. the energy saving and environment friendly recyclable pad pasting of the present invention uses acrylic acid and combines ferrous sulfate, polyvinyl alcohol, modified The ethylene-vinyl acetate copolymer formed by ethylene, vinylacetate, cooperation Isooctyl acrylate monomer, di-2-ethylhexylphosphine oxide phenylenediamine and Tert-butyl hydroperoxide 2- ethylhexyl carbonates realize EVA adhesive layers has viscosity and pressure-sensitive in room temperature, and pressure-sensitive changes Property EVA adhesive layers be water-based system environmental protection, have no irritating odor, be also convenient for energy saving and environment friendly recyclable pad pasting recycling and Recycling, greatly reduces pollution；Secondly, the peroxidating -2- ethylhexyl carbonates tert-butyl ester, triallyl isocyanide urea is further added Acid esters further improves the adhesive force of modified EVA adhesive layer and polypropylene film.
2. the energy saving and environment friendly recyclable pad pasting of the present invention, alkyl phenol polyoxyethylene ether, dimethyl sulfoxide (DMSO) is added in system The substance that solid material can be made to be more easy to be soaked in water allows the water to be deployed in solid by reducing its surface tension or interfacial tension In surface of material, or its surface is penetrated, and solid material is soaked；Secondly, addition polymethylphenylsiloxane improves system Compatibility and surface tension, be conducive to more preferable low realize masking liquid coating in coating process.
Specific implementation mode
With reference to embodiment, the invention will be further described：
Embodiment：A kind of energy saving and environment friendly recyclable pad pasting, including PET film 4, polypropylene film 1, pressure-sensitive modified EVA gluing Oxidant layer 2 and separated type material layer 3, the pressure-sensitive modified EVA adhesive layer 2 is between polypropylene film 1 and separated type material layer 3；
The pressure-sensitive modified EVA adhesive layer 2 is composed of the following components：100 parts of modified EVA aqueous solution, Isooctyl acrylate monomer 15 Part, 22 parts of deionized water, 6 parts of tert-butyl hydroperoxide 2- ethylhexyl carbonates, 5 parts of di-2-ethylhexylphosphine oxide phenylenediamine, polymethyl-benzene base 3 parts of siloxanes, 2.5 parts of the peroxidating -2- ethylhexyl carbonates tert-butyl ester, 1.4 parts of Triallyl isocyanurate, terpene resin 1.3 parts, 0.9 part of alkyl phenol polyoxyethylene ether, 0.8 part of dimethyl sulfoxide (DMSO)；
