    Abstract: Compositions and methods for improving the efficiency and reliability of the thermal molding process used to manufacture starch-bound articles having a cellular structural matrix. The inclusion of significant quantities of pregelatinized starch within the starch-based molding composition greatly expands the acceptable operating windows for a variety of compositional and processing variables, such as initial water concentration of the molding composition, amount (fill weight) of the composition placed into the mold, mold temperature, and vent hole size. Pregelatinized starch in a range from about 12 % to about 50 % by weight of the overall starch content of the molding composition has been shown to greatly moderate or offset increased system reactivity caused by, e.g., increasing the water concentration, fill weight, mold temperature, and vent hole size. The balance of the starch in the molding composition comprises ungelatinized starch granules, which gelate during the heated molding process. The molding composition further includes substantially homogeneously dispersed fibers of high aspect ratio, an inorganic filler, a mold release agent, and water.

    Abstract translation: 用于提高用于制造具有细胞结构基质的淀粉结合制品的热模塑方法的效率和可靠性的组合物和方法。 在淀粉基成型组合物中包含大量预胶化淀粉大大地扩展了各种组合和加工变量的可接受的操作窗口，例如成型组合物的初始水浓度，放置在组合物中的组合物的量（填充重量） 模具，模具温度和通气孔尺寸。 预胶化淀粉在模塑组合物的总淀粉含量的约12％至约50％的范围内已经显示出极大的中度或抵消了增加的系统反应性，例如增加水的浓度，填充重量，模具温度 ，和通气孔尺寸。 模塑组合物中的淀粉的平衡包括未加胶的淀粉颗粒，其在加热的模塑过程中胶凝。 成型组合物还包括基本上均匀分散的高纵横比的纤维，无机填料，脱模剂和水。

    Abstract: The subject of the invention is a method for manufacturing a vapor-permeable insulation panel and a vapor-permeable insulation panel. The method according to the invention consists in the fact that, on the bottom and along not less than two vertical sides of a metal mold in the shape of a cuboid closed from the bottom with a horizontal rectangular or square bottom, to the edges of which the vertical sides are firmly and tightly attached, expanding foam (2) is poured by means of a mixer into the central free space limited by the layer of mineral wool (1) in the metal mold, and before the expanding foam (2) in which at least 80% of the cells are closed completely increases in volume, the metal mold is closed from above with a metal cover for the time of curing of the expanding foam.
