粘弹性聚合物是理想的减振降噪材料,它可以在相当宽广的范围内调整材料的组成和结构,以致在规定的振动频率下,具有需要的弹性模量和损耗因子,并且容易制作、施工方便以及成本低廉.当然,粘弹性聚合物绝大多数是有机高分子化合物,其弹性模量和损耗因子受温度和振动频率影响较大,所以在设计和使用上都有严格要求. Viscoelastic polymers are ideal vibration damping and noise reduction materials which can adjust the composition and structure of materials over a wide range of ranges so that they have the requisite modulus of elasticity and dissipation factor at the specified vibration frequency and are easy to make, Of course, the viscoelastic polymer is the most organic polymer compounds, the elastic modulus and loss factor temperature and vibration frequency of a greater impact, so in the design and use have strict requirements.
