橡胶止水带，这是一种主要用于在混凝土变形缝、伸缩缝等混凝土内部设置的止水带产品，具有以橡胶材料弹性和结构形式来适应混凝土伸缩变形的能力。
Rubber waterproof belt, which is mainly used in concrete deformation joints, expansion joints and other concrete interior set products, has the ability to adapt to concrete expansion deformation in the form of elasticity and structure of rubber materials.
本产品是利用橡胶的高弹性和压缩变形性，在各种荷载下产生弹性变形，从而起到紧固密封有效地防止建筑构件的漏水，渗水，并起到减震缓冲作用，可确保工程建筑物的使用寿命。
This product utilizes the high elasticity and compressive deformation of rubber to produce elastic deformation under various loads, so as to tighten and seal effectively to prevent the leakage and seepage of building components, and to play the role of shock absorption and buffer, so as to ensure the service life of Engineering buildings.
中埋式橡胶止水带接头方法有两种：一种是采用粘接剂进行冷接头，一种是使用热硫化模具进行热接。
There are two kinds of joint methods for medium-buried rubber water stop: one is to use adhesive for cold joint, the other is to use hot vulcanization die for hot joint.
下边就分别介绍下两种接头方法：粘接剂冷接是采用橡胶止水带专用冷接胶水、采用搭接法把止水带需要接头的断面用磨光机磨平5~10厘米、涂胶水压实即可，具有强度高、凝固快的优点、施工方便、省时省力，可达到一般工程质量要求。
The following two kinds of joint methods are introduced separately: cold bonding with adhesive is to use special cold bonding glue for rubber water stops, lapping method is used to smooth the section of water stops which need joints with a polishing machine of 5-10 cm, and glue is applied to compact it. It has the advantages of high strength, fast solidification, convenient construction, time-saving and labor-saving, and can meet the re of general engineering
现场热接硫化法接头是使用与止水带匹配的热硫化模具及生胶片现场硫化热接，施工难度大，但接头效果理想，适合对工程质量要求严格的项目。
On-site hot vulcanization joints are hot vulcanization joints of hot vulcanization moulds and biofilm matched with water stop belts, which are difficult to construct, but the effect of joints is ideal and suitable for projects with strict engineering re

中埋式止水带广泛应用于水利、水电、堤坝涵洞、隧道地铁、人防工事、高层建筑的地下室和停车场等工程中变形缝止水。中埋式止水带则是在浇注混凝土时被预埋在变形缝内,与混凝土连成一体,利用橡胶的高弹性和压缩变形性能,在不同载荷下产生弹性变形,从而发挥紧固密封功能,有效地防止建筑构件漏水、渗水,并起到减震和缓冲作用,确保工程建筑构件的使用寿命。
Medium-buried water-stop belts are widely used in water conservancy, hydropower, dam and culvert, tunnel and subway, civil air defense works, basement of high-rise buildings and parking lot. Medium-buried water-stop belt is embedded in the deformation joint when pouring concrete, which is connected with concrete. By using the high elasticity and compressive deformation of rubber, it can produce elastic deformation under different loads, thus exerting the function of tightening and sealing, effectively preventing the leakage and seepage of building components, and playing the role of shock absorption and buffer to ensure the service life of engineering building components.
止水带老化后物理性能
Physical properties of water stop after aging
与老化前相应的物理性能对比可以发现,普通硫磺硫化体系低温硫化时老化性能不能满足技术标准要求;普通硫磺硫化及促进剂硫化的三元乙丙橡胶止水带经过70℃×168 h的热空气老化,强度均有所下降;过氧化物硫化的止水带经热空气老化后强度有所增加。且140℃硫化温度下,过氧化物硫化体系热空气老化后的硬度变化较其他硫化体系的小
Compared with the corresponding physical properties before aging, it can be found that the aging properties of ordinary sulfur vulcanization system can not meet the re of technical standards at low temperature; the strength of EPDM water-stop belt vulcanized by common sulfur vulcanization and accelerator decreases after hot air aging at 70 168 h; and the strength of water-stop belt vulcanized by peroxide increases after hot air aging. The hardness change of peroxide vulcanization system after hot air aging is smaller than that of other vulcanization systems at 140 C vulcanization temperature.
