Embodiment 1
[0041] A method for preparing a high-performance water-based pressure-sensitive adhesive, comprising the following steps,
[0042] ① Seed emulsion preparation: mix 100 parts by weight of deionized water, 0.1-0.7 parts by weight of emulsifier, and 0.4-1.2 parts by weight of pH regulator, stir evenly, and mix 60--88 parts by weight of alkyl carbon atoms 1--6 alkyl methacrylates, 5--22 parts by weight of alkyl acrylates with 4--18 alkyl carbon atoms, 0.01-0.1 parts by weight of chain transfer agent, using 100- Stir evenly at a speed of -500 rpm, start to heat up to 60-90°C, pass nitrogen through the system to remove oxygen, and then add 0.3-3.0 parts by weight of initiator to the system, and the initiation system starts to polymerize, and the reaction is 10- -50 minutes, obtain seed emulsion;
[0043] ② Pre-emulsion preparation: Mix 400 parts by weight of deionized water and 0.4-2.8 parts by weight of emulsifier, stir evenly at a stirring speed of 300--800 rpm, and then slowly m...
Embodiment 2
[0053] A high-performance water-based pressure-sensitive adhesive comprises the following components in mass percent:
[0054] Acrylate monomer 40-45%;
[0055] Functional monomer 2-10%;
[0056] Emulsifier 1.1-2.0%;
[0057] Stabilizer 1-4%;
[0058] Initiator 0.5-0.7%;
[0059] Water 30-50%;
[0060] The percentage sum of each component is 100%
[0061] Wherein, the acrylate monomer is: one or more of methyl acrylate, ethyl acrylate, butyl acrylate, isooctyl acrylate, lauryl acrylate and octadecyl acrylate;
[0062] The functional monomers are: acrylic acid, methacrylic acid, maleic anhydride, itaconic acid, hydroxyethyl acrylate, hydroxyethyl methacrylate, hydroxypropyl acrylate, methylol acrylamide, acrylamide and glycidyl methacrylate one or more of esters;
[0063] The emulsifier is an anionic emulsifier and a nonionic emulsifier combined to form a composite emulsifier; the anionic emulsifier is sodium vinyl sulfonate, sodium allyl sulfonate, allyl polyether sulfa...
Embodiment 3
[0065] A kind of high-performance water-based pressure-sensitive adhesive, differs from implementation two in that the mass percentage is as follows:
[0066] Acrylate monomer 45-70%;
[0067] Functional monomer 2-10%;
[0068] Emulsifier 1.1-2.0%;
[0069] Stabilizer 1-4%;
[0070] Initiator 0.5-0.7%;
[0071] Water 30-50%;
[0072] The percentage sum of each component is 100%.
