| titleOfInvention | Blow-molded foam and process for producing the same |
| abstract | A molten resin mixed with a blowing agent is extruded by an extruder to form a cylindrical foamed parison, which is placed in a mold and blow molded to obtain a hollow foamed blow molded article.n n n In this case, when polypropylene resin was used as the base resin, a molded article having a high foaming ratio and a thick thickness could be obtained.n n n In the present invention, in manufacturing a foam blow molded article, a base resin having a polypropylene resin as a main component, a melt tension (MT) at 230 ° C. of 10 gf or more, and a melt flow rate (MFR) of 0.5 g / 10 min or more are used. do. A foaming agent is added to this base resin and melt-kneaded by an extruder under high temperature, high pressure, and it is made into a foamable melt, and this melt is extruded and foamed by the die 5, and the cylindrical foamed parason 4 is formed. Thereafter, the molds 6 and 6 are clamped to place the parison 4 in the softened state into the molds 6 and 6, and at the same time, the gas inlet 7 The blown gas is blown in the mold) and blow molded into a hollow shape as it is to form a foamed blow molded product. |
