摘要： A barrier liner for sealing reinforced composite vessels at cryogenic temperatures is provided wherein the barrier liner is composed of a polymeric composition containing a curing agent, such as a methyl bis-methyl anthranilate, and an elastomer adhesive, such as a two-part polyether based urethane adhesive. A method of manufacturing and applying the barrier liner is also provided, including the steps of mixing and degassing the polymeric composition and introducing the polymeric composition between two polyethylene carrier sheets. The two carrier sheets and the intermediate polymeric composition layer are then passed between two sizing rollers set apart at a predetermined distance. The encapsulated polymeric composition is then partially cured to a tacky gel state and cooled to arrest polymerization until application of the gel layer. The gel layer and the two carrier sheets can then be cut into any desired shape such as strips, and applied to the inner surface of a vessel. The interior wall of the vessel may be heated prior to application of the gel layer. To apply the polymeric gel layer, one of the carrier sheets is removed to expose a tacky surface of the polymeric gel layer which is then applied to the vessel wall. When application of the polymeric gel layer is complete, the gel layer may be fully cured at ambient temperature and pressure to form a hardened barrier liner which is capable of maintaining a barrier to fluids at cryogenic temperatures.

摘要： A flexible, e.g. polyurethane, open cell foam sheet is impregnated with a controlled amount of a liquid polymerizable resin system which cures at ambient temperature, and the resin impregnated sheet is immediately chilled at a suitably reduced temperature, e.g. 40.degree. F. or below, to arrest polymerization or hardening. The resulting resin impregnated sheet is stored at such reduced temperature. When needed for adhesive bonding the chilled resin impregnated sheet, cut to the desired pattern or size, is applied between the surfaces of objects to be bonded, e.g. fiber reinforced polyurethane insulation blocks and plywood strips, or such insulation blocks and the steel hull of a liquid natural gas (LNG) container or marine tanker. With or without the application of bonding pressure, as the temperature of the resin impregnated sheet rises to ambient temperature, curing of the resin in the sheet to the solid state takes place, and bonding of the adjacent surfaces of the objects occurs, substantially without extrusion of any excess resin from the sheet, the open cell foam sheet containing the cured resin forming an integral part of the resulting bondline.
摘要翻译：灵活的，例如聚氨酯，开孔泡沫板用可控量的在环境温度下固化的液体可聚合树脂体系浸渍，并且树脂浸渍的片材在适当降低的温度下立即冷却，例如， 40°F以下，停止聚合或硬化。所得到的树脂浸渍片材在这样的还原温度下保存。当需要粘合时，将被切割成所需图案或尺寸的冷冻树脂浸渍片施加在被粘合物体的表面之间，例如，纤维增强聚氨酯绝缘块和胶合板条，或这种绝缘块和液体天然气（LNG）容器或船用油罐的钢船体。随着或不施加粘合压力，随着树脂浸渍片材的温度升高到环境温度，使得片材中的树脂固化成固态，并且基本上不挤出物体的相邻表面的粘结的任何多余的树脂，含有固化树脂的开孔泡沫片形成所得粘结线的一部分。
