Abstract:
    The present invention is room temperature cross-linking process of preparing silane cross-linked polyethylene, and the silane cross-linked polyethylene is prepared with grafting material and catalytic material in the weight ratio of 5-20 to 1 and through room temperature cross-linking. The grafting material consists of polyethylene resin 100 weight portions, alkenyl alkoxy silane 0.5-5 weight portions, alkyl trimethoxy silane 0.5-3 weight portions, titanium-alkoxide chelate 0.5-3 weight portions and free radical initiator 0.01-2 weight portions. The catalytic material consists of polyethylene resin 100 weight portions, water generating agent 0.5-30 weight portions, cross-linking catalyst 1-5 weight portions. Compared with available technology, the present invention has the features of advanced technological process, high product yield, low power consumption, excellent product performance, etc.
