Summary: | The invention discloses a special epoxy resin potting adhesive The special epoxy resin potting adhesive for ignition coils comprises a component A and a component B in a mass ratio of 5:1. The component A comprises the following ingredients in parts by mass: 100 parts of bisphenol A epoxy resin, 0.1-0.2 part of PEO-PPO-PEO (polyoxyethylene-polypropylene oxide-polyoxyethylene) triblock copolymer, 20-25 parts of carboxy-terminated liquid nitrile-butadiene rubber, 10-20 parts of micro silicon powder, 5-10 parts of aluminum hydroxide and 5-10 parts of ethylene glycol diglycidyl ether. The component B comprises the following ingredients in parts by mass: 100 parts of liquid methyltetrahydrophthalic acid, 0.5-1 part of PEO-PPO-PEO triblock copolymer and 20-25 parts of calcium carbonate. The special epoxy resin potting adhesive has the effect of lowering water absorptivity.
