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.

本文从某地区工业废弃物处理的角度出发，研究了汽车废橡胶作为木材-橡胶复合材料的再利用问题。（1）橡胶屑-杉木复合板的导热系数约为0.1W/m·K，与针叶树木材的导热系数相当。将粉碎前呈管状的废橡胶插入夹层板中，研究了废橡胶管直径和排列方式对夹层板性能的影响。其导热系数在0.11 ~ 0.13W/m·k之间，板材内部结构对导热系数的影响较小。B）制备了橡胶-木屑复合刨花板，并对其热性能进行了测试。当密度在0.3 ~ 0.5g/cm^3范围内变化时，其导热系数在0.1 ~ 0.18W/m·K之间，可作为墙体、天花板和地板的保温材料 ...更多信息 房屋的实际尺寸，并评估了面板的热性能。在复合板的两个表面内放置热电偶，并在夏季和冬季测量温度的趋势。通过温度趋势和热传导率的测量结果，对模型房屋中各墙板的热价值进行了评估。结果表明，在两个季节都没有阳光照射的情况下，屋顶和墙体的热损失都很大。从提高热效率的角度来看，上述部位的热流是很重要的，本文所研究的板材，即橡胶夹芯板和橡胶-木屑复合刨花板，不仅从热性能的角度来看，而且从改善空气环境条件的角度来看，因为这些材料含有大量的碳，如果橡胶废料作为燃料燃烧，这些碳将被释放到空气中。总之，这些板的使用是有效的，作为工业废物问题的改善，并且橡胶废物在不同类别的工业（例如汽车和木材工业）之间的局部再利用是重要的。少
