The waterstop is characteristic of high elastic deformation under stress by using rubbermaterial and made of sealing structure of products. Joint sealing deformation is widely used inwater conservancy and hydroelectric power, dams, tunnels, culverts, high-rise buildings, civil air defense basement and parking lot and other engineering. The rubber sealing strip is in pouring concrete is embedded in the deformation joint with concrete into a whole, can effectively prevent the construction deformation joint seepage, Water Leakage, and play abuffer role, so as to ensure the project construction waterproof requirements in. The country about the rubber waterstop technical standards are as follows: 1) executive standard: GB18173.2-2000 "polymer waterproof material sealing strip" test item performance of B type S type J hardness (shore A) of 60 ± 560 ± 560 ± 5 tensile strength ≥ 15, MPa ≥ 12 ≥ 10 elongation ≥ 380,% more than 380 ≥ 300 compression permanent deformation of 70 °C× 24h,% ≤ 35 ≤ 35 ≤ 3523 °C × 168h,% ≤ 20 ≤ 20 ≤ 20 tear strength ≥ 30, KN/m ≥ 25 ≥ 25 brittle temperature, °C - 45 ≤ 40 ≤ 40 hot air aging at 70 °C for 168h change of hardness (Shore Er A), degree ≤ +8 ≤ +8 / tensile strength, MPa ≥ 12 ≥ 10 / elongation,% ≥ 300 ≥ 300 / 100 °C× 168h change of hardness (shore A), / / / ≤ +8 tensile strength, elongation at break of MPa / / ≥ 9,% / / ≥ 250 ozone aging 50pphm:20%, 48H 2 Level 2 level 0 we can use rubber waterstop according to their use can be divided into the following three categories: a) forseam waterstop in deformation joints, expansion, B; b) is applicable to the construction seam waterstop, denoted by S; c) applicable to special anti-aging requirements joint with sealing strip, with J table Show.
