Embodiment Construction
[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments!
[0025] A manufacturing method of a polytetrafluoroethylene insulating self-adhesive tape, comprising the following manufacturing steps:
[0026] 1. Production of PTFE Dispersion Resin Masterbatch
[0027] 1. Mix the pigment with anhydrous ethanol in a weight ratio of 1:0.8-1.2, then grind it continuously for 20-24 hours, take it out, dry it at 100-150°C and sieve it, the sieve is 300-500 mesh. The preferred weight ratio of pigment to absolute ethanol is 1:1. Mixing and grinding can be placed in a corundum ball mill, and the mixture should not exceed one-third of the volume of the container, otherwise the grinding effect will be affected. Among them, the index requirements of the pigment: (1), have high heat resistance, stable color body performance at 400 ℃, bright color, no fading;
[0028] (2) It requires high purity, fine and uniform pa...
