Embodiment 1
[0032] A method for preparing a high-strength vibration-resistant structural adhesive, the structural adhesive includes component A and component B, wherein component A includes 30-60 parts of α-methyl methacrylate, 2-hydroxyethyl methacrylate 5-10 parts of ester, 5-10 parts of trimethylolpropane trimethacrylate, 7-15 parts of methacrylic acid, 1-3 parts of hydroquinone, 1-5 parts of disodium edetate, polyurethane modified 7-15 parts of acrylate, 7-15 parts of chloroprene rubber and additives; component B includes 15-40 parts of dibenzoyl peroxide, 40-60 parts of epoxy resin, 15 parts of dioctyl terephthalate -35 parts and additives; wherein, the additives include 1-10 parts of tertiary amine and 3-8 parts of precipitated silica, and the additives include 4-8 parts of precipitated silica and 2-6 parts of Teng's blue.
[0033] The specific production and processing steps are:
[0034] ①. First, add 30 parts of α-methyl methacrylate, 5 parts of 2-hydroxyethyl methacrylate, 5 pa...
Embodiment 2
[0038] The difference between this embodiment and embodiment 1 is: the specific production and processing steps are:
[0039] ①. First, add 45 parts of α-methyl methacrylate, 7.5 parts of 2-hydroxyethyl methacrylate, 7.5 parts of trimethylolpropane trimethacrylate and 11 parts of methacrylic acid into the reactor Inside, start the reactor to stir the materials so that the materials are mixed evenly to obtain mixture I; then add 2 parts of hydroquinone and 3 parts of disodium ethylenediamine tetraacetate into the mixture I in the reactor, and continue to stir and mix evenly Obtain mixture II; then add 11 parts of polyurethane modified acrylate and 11 parts of chloroprene rubber into mixture II in the reaction kettle, continue to stir and mix uniformly to obtain mixture III; then add 5.5 parts of tertiary amine and 5.5 parts The precipitated silica was added to the mixture III in the reaction kettle, and after mixing evenly, the reaction kettle was evacuated for defoaming treatm...
Embodiment 3
[0043] The difference between this embodiment and embodiment 1 is: the specific production and processing steps are:
[0044] ①. First, add 60 parts of α-methyl methacrylate, 10 parts of 2-hydroxyethyl methacrylate, 10 parts of trimethylolpropane trimethacrylate and 15 parts of methacrylic acid into the reactor Inside, start the reactor to stir the materials so that the materials are evenly mixed to obtain a mixture I; then add 3 parts of hydroquinone and 5 parts of disodium edetate into the mixture I in the reactor, and continue to stir and mix evenly To obtain mixture II; then add 15 parts of polyurethane modified acrylate and 15 parts of chloroprene rubber into the mixture II in the reaction kettle, and continue to stir and mix uniformly to obtain mixture III; then add 10 parts of tertiary amine and 8 parts of The precipitated silica was added to the mixture III in the reaction kettle, and after mixing evenly, the reaction kettle was evacuated for defoaming treatment to obt...
