Preparation method of aramid fiber cloth high-intensity high-flexibility copper-clad plate

The invention provides a preparation method of an aramid fiber cloth high-intensity high-flexibility copper-clad plate. The method comprises the following steps of 1, uniformly mixing 0.5 to 5.0 partsof curing agents, 0.005 to 2.0 parts of accelerators, 50 to 150 parts of epoxy resin and 20 to 50 parts of solvents into a mixed solution through being metered in parts by weight; 2, soaking the aramid fiber cloth by alcohol solvents; performing high-temperature baking at 180 to 250 DEG C; then, soaking the aramid fiber cloth by silane coupling agent treatment agents; performing high-temperaturedrying to obtain the treated aramid fiber cloth; 3, soaking the treated aramid fiber cloth into mixed glue liquid in the first step; performing drying to obtain a semi-cured sheet; overlapping the semi-cured sheet with a copper foil; performing high-temperature and high-pressure shaping to obtain the aramid fiber cloth high-intensity high-flexibility copper-clad plate. 本发明提供一种芳纶布高强度高柔韧性覆铜板的制备方法，该方法包括如下步骤：步骤一，按照重量组份计，将0.5～5
