Abstract : It is studied the preparation technics deeply based on the performance characters of adhesive materials, then put
forward the solution to every influencing factor during the preparation process, and described the environment control of
preparation process. At the same time, it is also developed the coating system equipment, the cooling equipment and the
scratch equipment suitable for the processing of retard-bonded prestressing strand, which provides the equipment guarantee to
the production of retard- bonded prestressing strand.
