Embodiment 1
[0031] Weigh each component according to the following mass percentages:
[0032] A component:
[0033]
[0034]
[0035] B component:
[0036] Bisphenol A type epoxy resin (epoxy equivalent is 186g / eq) 80wt%
[0037] Butyl glycidyl ether 20wt%
[0038] The production process of component A is divided into eight steps:
[0039] Step 1: Add the measured II-generation water-based epoxy resin curing agent, 16.5wt% water, and dispersant into the material tank, disperse and stir evenly.
[0040] Step 2: Add quartz powder, barium sulfate, and talcum powder into the material tank and continue to disperse and stir evenly.
[0041] Step 3: Grind the above uniformly stirred and dispersed materials through a sand mill, and the fineness is controlled to be ≤50 μm.
[0042] Step 4: Add the conductive fiber, the conductive paste and the remaining 16.5wt% of water and stir in the disperser to disperse evenly.
[0043] Step 5: Filter with a 200-mesh filter.
[0044] Step 6: Add w...
Embodiment 2
[0052] Weigh each component according to the following mass percentages:

[0057] Butyl glycidyl ether 5%
[0058] C12-Myristyl Glycidyl Ether 10%
[0059] The production process of component A is divided into eight steps:
[0060] Step 1: Add the measured II-generation water-based epoxy resin curing agent, 15% water, and dispersant into the material tank, disperse and stir evenly.
[0061] Step 2: Add titanium dioxide, silicon micropowder, and talcum powder into the material tank and continue to disperse and stir evenly.
[0062] Step 3: Grind the above dispersed and stirred materials through a sand mill, and the fineness is controlled to be ≤50 μm.
[0063] Step 4: Add conductive fiber, conductive paste and the remaining 15% of water to disperse and stir evenly in a disperser.
[0064] Step 5: Filter with a 200-mesh filter.
[0065] Step 6: Add color...

[0078] 1,4-Butanediol diglycidyl ether 5%
[0079] C12-Myristyl Glycidyl Ether 5%
[0080] The production process of component A is divided into eight steps:
[0081] Step 1: Add the measured II-generation water-based epoxy resin curing agent, 14% water, and dispersant into the material tank, disperse and stir evenly.
[0082] Step 2: Add titanium dioxide, silicon micropowder, and talcum powder into the material tank and continue to disperse and stir evenly.
[0083] Step 3: Grind the above dispersed and stirred materials through a sand mill, and the fineness is controlled to be ≤50 μm.
[0084] Step 4: Add conductive fiber, conductive paste and the remaining 14% of water to disperse and stir evenly in a disperser.
