Embodiment 1
[0015] A special antistatic paint for cover tape, including the following raw material components in mass percentage: 20 grams of PEDOT / PSS (solid content 1.3%), 0.5 grams of Dynol 604 wetting agent, styrene-butadiene latex (solid content 30%) 10 grams, 5 grams of dimethyl sulfoxide, 0.1 grams of Dow Corning DC-51 slip agent, 64.4 grams of water.
[0016] Add PEDOT / PSS to the water, stir for 10 minutes, add Dynol 604 wetting agent and styrene-butadiene latex to the above solution and stir for 15 minutes, then add dimethyl sulfoxide and Dow Corning DC-51 slip agent to the above In the mixed solution, fully stir evenly for 2 hours to obtain the special antistatic coating for the cover tape. Coat it on the rubber surface of the cover tape with a No. 5 wire rod, and dry it at 110°C to measure the antistatic performance and the influence on the hot pressing performance.
[0017] The antistatic performance of the above formula is 10 6 Ω / □, the tensile impact test after hot pressin...
