Dispersion of antioxidant in cross-linkable polyethylene |
摘要 |
This invention is an improved method for dispersing antioxidant material in cross-linkable insulation for electric cables. The antioxidant, which has a high melting point, is dissolved in a carrier, preferably the cross-linking agent, to obtain a solution of low melting point that is dispersed through the pellets of insulation when the ingredients are mixed in a blender. Improvements in the blender cycle reduce the content of fines, improve dispersion of the antioxidant and shorten the blending cycle. The preferred ingredients used are 4,4'-thiobis (6 tert-butyl-m-cresol) as the antioxidant and dicumyl peroxide as the cross-linking agent.
