Abstract

The preparation method for a low temperature detachable anaerobic glum overcomes the poor maintainability, hard assembly to non-resistance heat material and part and depressed reliability, and comprises: A. by weight share, mixing 50-95 methyl dimethacrylate and 0.01-2 stabilizer to dissolve at 45-55Deg; B. adding 0.1-5 accelerant and 0.1-5 o-benzene sulfinamide; C. adding 10-15 unsaturated polyester, 5-50 modifier and 0.1-5 gas-phase SiO2 into the product in B, and cooling to room temperature; D. adding 1-10 oxide to stir evenly. This invention has little effect to adhesive strength and high benefit with low cost.

Description

technical field [0001] The invention relates to a detachable anaerobic adhesive and a preparation method thereof. Background technique [0002] Before the emergence of chemical locking and sealant technology, people used a variety of mechanical methods for thread loosening. Loosening is basically prevented, and leakage at the thread cannot be avoided. The birth of anaerobic adhesives has solved the above problems. However, after adopting the adhesive bonding technology, it is difficult to disassemble the threaded parts and flange parts during product maintenance, especially the high-strength anaerobic adhesive and large-diameter threaded locking parts cannot be disassembled at room temperature. At present, the high-temperature heating disassembly method is mainly used. The heating must reach above 200°C, and sometimes it must reach 300-400°C to disassemble. However, some parts are limited by materials (such as cast aluminum, magnesium alloy) and cannot be heated at high te...
