环保型聚碳酸亚丙酯复合调湿材料的性能研究

Performance Research of Environmental Friendly humidity-controlling Poly Propylene Carbonate Composite Material

以溶液共混法将聚碳酸亚丙酯(PPC)、木质素、沸石、硅藻土制得复合材料,测试复合材料的吸放湿性能。结果表明:无机调湿材料吸放湿速度快,但湿容量小;有机调湿材料吸放湿速度中等或较慢,但湿容量大。而通过复合无机与有机调湿材料料,可以得到吸放湿速度快且湿容量大的调湿材料。

The solution mixing is used to fabricate a series of poly propylene carbonate、Lignin、zeolite、di-atomite composites ,the moisture absorption and desorption property are tested. It is found that inorganic humidity cont rolling materials had a high absorbing and releasing moisture speed ,but lit tle moisture ca-pacity.organic humidity controlling material had great moisture capacity ,but a low absorbing and relea-sing moisture speed .Through the compostion of inorganic and organic materials could obtain the humidity cont rolling materials with large moisture capacity and high absorbing and releasing moisture speed .
