Reuse of rubber waste of automobiles as wood-rubber composite materials was studied from the viewpoint of a problem of an industry wastes management in a local area.a) The thermal conductivity of a sandwich panel of rubber chips and plywoods was about 0.1W/m・K,and is almost equivalent to that of conifer wood. The rubber waste whose form is tubelike, before chipped, was also inserted in the sandwich panels, and the effects of the tube diameter and the arrangement were studied. Those thermal conductivity ranged from 0.11 to 0.13W/m・k, and the effects of the structure inside of the panel was small.b) Rubber-wood chips composite particle board was made and the thermal property was examined. The thermal conductivity ranged between 0.1 to 0.18W/m・K when the board density changes between 0.3 to 0.5g/cm^3.This board can be used as building materials for thermai insulation of walls, ceiling and floors.c) The rubber sandwiched panels were build in as walls, floors and ceiling members of a model … More house in actual sizes, and the thermal properties of the panels were evaluated. Thermocouples were located inside at both surfaces of the composite panel, and the trend of the temperature was measured in summer and winter seasons. The thermal valance of each panels located in the model house were evaluated from the results of the temperature trend and the thermal conductivity of the panels. The results showed that the thermal loss was large at roofs and the walls where there is no sunshine in both seasons. From the view point of improvement of thermal valance, the heat flow at above places was important.The boards studied here, i.e.the rubber sandwiched panel and the rubber-wood chips composite particle board are efficient not only from the viewpoint of the thermal property but also from improvement of environmental condition of the air, because these materials contain much of carbon which would be released to the air if the rubber wastes are burned as fuel. Conclusively, the use of these boards are efficient as improvement of the problems of industry wastes, and the local reuse of rubber waste between different category of industries such as automobile and wood industries is important.

从当地工业废物管理问题的角度出发，对汽车橡胶废料作为木胶复合材料的再利用进行了研究。a)橡胶碎片和胶合板夹芯板的导热系数约为0.1W/m·K，几乎与针叶树的导热系数相当。将切片前的管状橡胶废料插入夹芯板中，并研究了管直径和排列的影响。其导热系数范围为0.11至0.13W/m·k，面板内部结构的影响较小。b)制备橡胶木片复合刨花板并检查其热性能。当板密度在0.3至0.5g/cm^3之间变化时，导热系数在0.1至0.18W/m·K之间。该板可用作墙壁、天花板和地板隔热的建筑材料。c) 将橡胶夹芯板作为实际尺寸的模型房屋的墙壁、地板和天花板构件，并评估面板的热性能。热电偶位于复合板的两个表面内部，测量夏季和冬季的温度变化趋势。根据温度趋势和面板导热率的结果评估了模型房屋中每个面板的热价。结果表明，在两个季节没有阳光照射的屋顶和墙壁处，热损失较大。从改善热价的角度来看，上述地方的热流很重要。这里研究的板材，即橡胶夹芯板和橡胶木片复合刨花板，不仅从热性能的角度来看是有效的，而且从改善空气环境条件的角度来看也是有效的，因为这些材料含有大量的碳，如果橡胶废料作为燃料燃烧，碳会释放到空气中。总之，这些板材的使用对于改善工业废物问题是有效的，并且汽车和木材工业等不同类别工业之间橡胶废物的本地再利用非常重要。较少的
