摘要:
Components formed of blow molded thermoplastic compositions are described. The blow molded thermoplastic compositions exhibit high strength and flexibility. Methods for forming the thermoplastic compositions are also described. Formation methods include dynamic vulcanization of a composition that includes an impact modifier dispersed throughout a polyarylene sulfide. A crosslinking agent is combined with the other components of the composition following dispersal of the impact modifier. The crosslinking agent reacts with the impact modifier to form crosslinks within and among the polymer chains of the impact modifier. The compositions can exhibit excellent physical characteristics at extreme temperatures and can be used to form, e.g., tubular member such as pipes and hoses and fibers.

The present invention relates to a surface-treated steel sheet coated with a chromate layer having excellent corrosion resistance, fuel resistance and seam weldability, and a chromate solution used for preparing the surface-treated steel sheet. Specifically, the chromate solution of the present invention comprises (a) a main solution prepared by adding to a chrome solution having 0.4 to 0.8 of trivalent chrome composition and 7 to 50 g/l of dissolved chrome, on the basis of the chrome in the chrome solution, 50 to 80 w% of phosphate, 20 to 40 w% of fluoric acid, 300 to 2000 w% of colloidal silica, 5 to 15 w% of sulfuric acid, and 25 to 40 w% of sodium phosphate, and (b) a hardener solution containing added epoxy silane or glycidyl silane of 2 to 10 w% on the basis of total hardener solution, the pH of which is controlled between 2 and 3 Wherein 10 to 60 w% of the hardener solution being added to the main solution. The chromate solution is coated on a cold-rolled steel sheet plated with zinc or zinc alloy and dried at a baking temperature of 140 to 250 DEG C to prepare a surface-treated steel sheet for a fuel tank of an automobile.
