•主要以天然橡胶与各种合成橡胶为主要原料，掺加各种助剂及填充料，经塑炼、混炼、压制成型，其品种规格较多，有桥型、山型、P型、U型、Z型、乙型、T型、H型、E型、Q型等。背贴式橡胶止水带根据使用情况又可分类为中埋式橡胶止水带和背贴式橡胶止水带。
- mainly natural rubber and various synthetic rubber as the main raw material, and the filling material mixed with various additives, through plasticizing, mixing, molding, the more varieties of different specifications, bridge, mountain type, P type, U type, Z type, T type, type, H type, E type and Q type etc.. According to the usage, the back - up rubber waterproof belt can be classified as the embedded rubber water stop belt and the back - mounted rubber water stop belt.
•性能原理：
Performance principle:
•背贴式橡胶止水带是利用橡胶的高弹性，在各种荷载下产生弹性变形，从而起到坚固密封，有效地防止建筑构造的漏水，渗水并起到减震缓冲作用。在许多工程建筑设计中，土建、水土结构之间都有一定的伸缩要求，并存在防水防震等问题，因此采用和安装橡胶止水带是有效地解决以上种种问题的手段。本产品主要用于混凝土现浇时设在施工缝及变形缝内，与混凝土结构成为一体的基础工程、地下设施、隧道涵洞、输水渡槽、挡水坝等，确保工程建设的使用寿命。
Back rubber waterproof tape is made of high elasticity of rubber, produces elastic deformation under various loads, so as to play a strong sealing, effectively prevent the leakage of building structure, seepage, and play the role of damping buffer. In many engineering architectural design, there are certain requirements between the telescopic construction, soil structure, and there are problems such as waterproof and shockproof, so using and installing the rubber sealing strip is effective means to solve these problems. This product is mainly used in concrete cast-in-place construction joints and deformation joints, and foundation engineering, concrete structure has become one of the underground facilities, tunnel, culvert aqueduct, dam etc., to ensure the construction of service life.
