合成橡胶在国外被称为弹性体,弹性是此类材料最显著的特点,橡胶的弹性模量具有钢的二十万分之一,在很小的外力作用下就能伸长50%~1000%,外力消除后就能在数秒内恢复到接近原始尺寸。合成橡胶具有其它非金属和金属建筑材料所没有的伸缩性、防水性、气密性、阻尼性和缓冲性等特性,因而成为现代建筑材料中的一朵奇葩。目前,结构性橡胶建筑材料已发展到数千种之多。橡胶建筑材料在建筑物上的应用主要包括防水、抗震和密封等方面。从世界范围来看,建筑领域内橡胶用量最大的是防水,其次是抗震隔震,然后才是密封。 Synthetic rubber is called elastomer in foreign countries. Elasticity is the most prominent feature of this kind of material. The elastic modulus of rubber has one-hundredth of one-thousandth of that of steel. With a small external force, it can stretch by 50% to 1000% , The external force can be restored in a few seconds to close to the original size. Synthetic rubber has the characteristics of other non-metallic and metallic building materials scalability, water resistance, air tightness, damping and cushioning properties, which has become a wonderful work in modern building materials. At present, structural rubber building materials have grown to thousands of species. The application of rubber building materials in buildings mainly includes waterproofing, earthquake resistance and sealing. From a global perspective, the largest amount of rubber in the construction field is waterproof, followed by seismic isolation, and then sealed.
