Abstract: A thermoplastic multi-layer composite structure is disclosed and consists in a first embodiment of a co-extruded acrylic polypropylene outer skin and high melt strength polypropylene substrate which is attached to a first surface of a polypropylene foam core. An inner polypropylene skin can be provided and is attached to a second surface of the foam core. The foam core can either be constructed from an expanded polypropylene or an extruded polypropylene. Where an expanded polypropylene foam core is provided, the foam core is attached to the outer and inner skin through the use of a polypropylene adhesive. Where the extruded polypropylene foam core is provided, the skins can be attached to the foam core through a welding or bonding process in lieu of adhesives. The polypropylene adhesives can also be utilized for attaching the skins to the extruded foam core. Additionally, the extruded foam core can vary in density to provide a composite foam core. Preferably, the various densities of the composite foam core are arranged such that the lowest density foam is provided at the center of the core and the varying densities of the foam core extend outward from the center in numerical order.
Abstract translation: 公开了一种热塑性多层复合结构，其包括在丙烯酸聚丙烯外皮共挤出的第一实施方案和连接于聚丙烯泡沫芯的第一表面上的高熔体强度的聚丙烯基材。 可以提供内部聚丙烯皮肤并且附接到泡沫芯的第二表面。 泡沫芯可以由发泡聚丙烯或挤出聚丙烯构成。 当提供膨胀聚丙烯泡沫芯时，泡沫芯通过使用聚丙烯粘合剂附着到外皮和内皮上。 在提供挤出的聚丙烯泡沫芯的地方，皮肤可以通过焊接或粘合工艺代替粘合剂而附着在泡沫芯上。 聚丙烯粘合剂也可以用于将表皮粘附到挤出的泡沫芯上。 此外，挤出的泡沫芯可以在密度上变化以提供复合泡沫芯。 优选地，复合泡沫芯的各种密度被布置成使得最低密度泡沫被提供在芯的中心，并且泡沫芯的变化密度以数字顺序从中心向外延伸。

Abstract: A rotational molding method is provided consisting in a first method of spraying the inner mold area with an acrylic polyethylene alloy prior to loading the resin into the mold. The mold is then heated, rotated and cooled to form the molded part. The part is provided with a shinier and harder surface layer as compared to previous rotational molding methods. In a second method, in lieu of spraying, the acrylic polyethylene alloy is loaded into the mold with the resin. In the third and fourth methods, a drop box is provided for releasing resins into the mold. Other materials, in addition to acrylic polyethylene, can also be used with the various methods.
Abstract translation: 提供了一种旋转模制方法，其包括在将树脂加载到模具中之前用丙烯酸聚乙烯合金喷射内部模具区域的第一种方法。 然后将模具加热，旋转和冷却以形成模制部件。 与先前的旋转成型方法相比，该部件具有更亮和更硬的表面层。 在第二种方法中，代替喷涂，用树脂将丙烯酸聚乙烯合金装入模具中。 在第三种和第四种方法中，提供了用于将树脂释放到模具中的液滴盒。 除了丙烯酸聚乙烯之外，其他材料也可以用各种方法使用。
