[0014] In the present invention, the acrylate monomer can be self-made, and the preparation method includes: one or more of stearic acid, organic silicic acid, bisphenol A epoxy resin, lauric acid, and tricyclodecanedicarboxylic acid One or more of methylol acrylate, triethylene glycol, trimethylolpropane, pentaerythritol, polyether diol, polyester diol, polymerization inhibitor, and catalyst are put into the reactor and mixed , after the reaction. Preferably, the polymerization inhibitor is one or more of hydroquinone, p-hydroxyanisole, and 2,6-di-tert-butyl-p-cresol; the catalyst is 4-dimethylaminopyridine One or more of (DMAP), chloroplatinic acid, 1,3-divinyl-1,1,3,3-tetramethyldisiloxane platinum. Preferably, the reaction temperature is 40-110° C., and the reaction time is 2-10 h.
[0015] The acrylate monomer resin can also be obtained commercially, preferably, bisphenol A epoxy methacrylate, silicone modified acrylate, tricyclodecane dimethacrylate, polyurethane metha...

[0034] Embodiment 1~6
[0035]1) Configure stearic acid and hydroxymethyl acrylate in a weight ratio of 3:7 to form a matrix resin. Put 100 parts by weight of matrix resin standard and 0.01 parts by weight of hydroquinone into a power reactor, mix at 70°C for 30 minutes, add 0.07 parts by weight of DMAP and react for 150 minutes, and wait to cool to 50°C to obtain acrylate monomers. The number average molecular weight of cyclodecane methacrylate is not higher than 1000.
[0036] 2) Preparation of compound acid: mix maleic acid, ascorbic acid, 1,2-phthalic acid-2,2-dimethyl-1-(1-methylethyl)-3-(isobutyryloxy)propane Mix at least two of phenylmethyl ester and methacrylic acid, stir evenly at 50°C, and cool to room temperature. The specific components and dosage are shown in Table 1.
[0037] 3) Preparation of anaerobic adhesive: Add the acrylate monomer, initiator, accelerator, co-accelerator, tackifier, and compound acid prepared in step 1 into the mixer, stir at 80°C for 2...
