Embodiment 1
[0043] A kind of ultra-high temperature-resistant double-sided adhesive tape of this embodiment is prepared by the following method:
[0044] (1) First weigh 70 parts of methyl acrylate, 30 parts of ethyl acetate solvent and 1.5 parts of dilauroyl peroxide initiator; first put the solvent into the reactor, replace the air in the reactor with nitrogen, and heat to 135- At 145°C, drop methyl acrylate into the reaction kettle in 4-4.5 hours, keep warm for 3 hours, add initiator to the reaction kettle, keep warm for 2-3 hours, cool down, and discharge; add tackifier to polymerize rosin glyceride (purchased (Shenzhen Yoshida Chemical Co., Ltd.) 5 parts, 2 parts of vinyltriethoxysilane coupling agent, 2 parts of hexamethylene diisocyanate crosslinking agent, stir and disperse evenly, and then form a semi-finished base material;
[0045] (2) Add 8 parts of calcium carbonate after weighing the corresponding amount of semi-finished base material, stir and disperse, and then filter 500-...
Embodiment 2
[0058] A kind of adhesive of this embodiment, ultra-high temperature-resistant double-sided adhesive tape is prepared by the following method:
[0059] (1) First weigh 65 parts of phenylacrylate, 30 parts of isopropanol solvent and 1.2 parts of dilauroyl peroxide initiator; first put the solvent into the reactor, replace the air in the reactor with nitrogen, and heat to 135- 145°C, drop phenylacrylate into the reaction kettle in 4-4.2 hours, keep warm for 2.5 hours, add initiator to the reaction kettle, keep warm for another 2-3 hours, cool down, and discharge; add 5 parts of tackifier to polymerize rosin glyceride , 1.5 parts of vinyl tris (β-methoxy) silane coupling agent, 1.5 parts of isophorone diisocyanate crosslinking agent, stir and disperse evenly, and then form a semi-finished base material;
[0060] (2) Add 8 parts of calcium carbonate after weighing the corresponding amount of semi-finished base material, stir and disperse, and then filter 500-600 mesh to obtain sti...
