摘要
用热压工艺将汽车车顶饰件生产过程中的聚氨酯泡沫复合废料制成板材 ,研究了板材的性能与热压工艺之间的关系。试验结果表明 ,当热压温度为 15 0℃以上时 ,板材的弯曲强度可以达到 15 -2 8MPa ,板材的吸水率为 0 -2 % ,密度为 1 0 -1 2g cm3。其强度与中密度纤维板相当 ,密度则高于纤维板 ,吸水率大大低于纤维板。这种板材可望在公园设施、家具。
The polyurethane foam composite waste produced in the automotive roof lining production was press-formed into artificial board.The influence of the pressing parameter on the properties of the board was studied.The test results showed that the board formed under the temperature of above 150 ℃ had flexural strength of 15-28 MPa, water absorptivity of 0-2 % and density of 1.0-1.2 g/cm 3.The flexural strength is similar to that of the fiberboard with medium density,the density is higher and the water absorptivity much lower than that of the fiberboard.The board with this feature could be used for the application situations which need resistance to water and high density such as furnishings in park and acoustics area.
