1. , a kind of anti-electrostatic fire retardant nanofiber strengthens the steel-plastics composite pipe preparation method, by fiber or fabric is base-material, with the thermosetting resin adhesive is adhesive, add and join fire retardant, antistatic additive, curing agent and the agent of inserts composition adhering and solidifying, twine the agent of base-material limit coating adhering and solidifying in tubular mould top, the final pipeline that solidifies back formation and the combination of prefabricated ring flange accessory, the structure of pipeline comprises three layers:

  • at tubular mould(5) twine fiber or its fabric and evenly apply the formed inner liner (3) of thermosetting resin adhesive simultaneously with impervious or anti-wear performance with conduction and flame-retarding characteristic, on the basis that ring flange mould and inner liner (3) form, twine enhanced fiber or its fabric simultaneously evenly coating have the formed enhancing stress layer of thermosetting resin adhesive (2) of conduction and flame-retarding characteristic, on the surface of enhancing stress layer (2), twine the even thermosetting resin adhesive that applies of fine and close fiber or its fabric while and form surface conductance layer (1), it is characterized in that the preparation method of this multiple tube has been taked following technological improvement with conduction and flame-retarding characteristic;

    1. have to add in the conduction and the thermosetting resin adhesive of flame-retarding characteristic and joined the nano-calcium carbonate that improves each layer of multiple tube microstructure and do filler, the resin glue of per 100 parts of weight adds the nano-calcium carbonate of filling out 10-30 part,2. have to add in the conduction and the thermosetting resin adhesive of flame-retarding characteristic and joined the nanometer carbon black that improves each layer of multiple tube electric conductivity and do modifier, the resin glue of per 100 parts of weight adds the nanometer carbon black of filling out 0.5-3 part,3. be provided with the enhancing skeleton of forming by the helical form steel wire (2A) at enhancing stress layer (2).
