摘要： Composites of plastic materials for filling enclosed spaces are prepared by coating the surface of a shaped core material with a layer of expandable resin particles plus a binder such as asphalt. The composite is then placed within the cavity to be filled and heated whereby the rest of the enclosed space is filled with the core material and the expanded particles and binder. The core material may comprise thermostable expandable cellular material. Alternately, the layer of expandable resin particles with the binder can be placed in enclosed spaces in the absence of the shaped core material and expanded to fill the void.
摘要翻译：用于填充封闭空间的塑料材料的复合材料通过用可膨胀树脂颗粒层和沥青等粘合剂层涂覆成形芯材的表面来制备。然后将复合材料放置在空腔内以进行填充和加热，由此封闭空间的其余部分填充有芯材料和膨胀颗粒和粘合剂。芯材料可以包括热稳定的可膨胀的细胞材料。或者，具有粘合剂的可膨胀树脂颗粒层可以在没有成形芯材料的情况下放置在封闭空间中并膨胀以填充空隙。

摘要： 1. A CONTINUOUS METHOD FOR FORMING A SUBSTANTIALLY WATER IMPERMEABLE PLASTIC FOAM STRUCTURE USEFUL IN FROST BARRIER AND THERMO-INSULATION CONSTRUCTIONS COMPRISING: A. MIXING PARTICLES OF A FOAMABLE THERMOCOLLAPSE RESISTANT PLASTIC MATERIAL WITH A LIQUID BINDER HEATED SUFFICIENTLY TO CAUSE SAID PARTICLES TO FOAM, SAID HEATED BINDER SUBSTANTIALLY UNIFORMLY COATING THE OUTSIDE SURFACE OF SAID PARTICLLES; B. CONTINUOUSLY FOAMING SAID PARTICLES DURING SAID MIXING TO A VOKUME OF AT LEAST 50% OF THEIR FINAL FORMED VOLUME; C. FORMING AND RESTRAINING SAID FOAMING PARTICLES AND LIQUID BINDER THEREBY CAUSING SAID FOAMING PARTICLES TO SECURELY BONDED INTO A MATRIX OF SAID BINDER; AND D. COOLING SAID RESTRAINED PARTICLES AND LIQUID BINDER TO A TEMPERATURE AT WHICH SAID PARTICLES WILL NOT CONTINUE TO FOAM AND AT WHICH SAID LIQUID BINDER IS TRANSFORMED INTO ESSENTIALLY SOLID BINDER.
