三元乙丙复合GB止水带

三元乙丙橡胶在臭氧浓度 50pphm、拉伸30％的条件下，可达150h以上不龟裂。并且具有很强的耐腐蚀性，由于乙丙橡胶缺乏极性，不饱和度低，因而三元乙丙橡胶止水带对各种极性如醇、酸、碱、氧化剂、制冷剂、洗涤剂、动植物油、酮和脂等均有较好的抗耐性！由于乙丙橡胶分子结构中无极性取代基，分子内聚能低，分子链可在较宽范围内保持柔顺性，仅次于天然橡胶和顺丁橡胶，并在低温下仍能保持。
Ethylene propylene diene monomer (EPDM) rubber can reach 150 hours without cracking under the condition of 50 PPHM ozone concentration and 30％ stretching. Because of the lack of polarity and low unsaturation of EPR, EPR waterproof belt has good resistance to various polarities such as alcohol, acid, alkali, oxidant, refrigerant, detergent, animal and vegetable oil, ketone and fat. Due to the absence of polar substituents in the molecular structure of ethylene-propylene rubber, the molecular cohesion energy is low, and the molecular chain can be maintained in a wide range of flexibility, second only to natural rubber and cis-butadiene rubber, and can be maintained at low temperatures.
1) 塑性防渗适应基面变形性强：SR防渗盖片是由SR塑性止水材料和增强型聚酯布复合而成的，与混凝土基面粘结的是SR塑性止水材料，当混凝土基面变形时，SR塑性止水材料发生塑性变形，从而避免SR防渗盖片受到应力破坏；
1) Plastic impervious material has strong adaptability to base deformation: SR impervious cover sheet is composed of SR plastic water-proof material and reinforced polyester cloth, and bonded with concrete base surface is SR plastic water-proof material. When concrete base surface is deformed, SR plastic water-proof material will plastic deformation, thus avoiding stress damage of SR impervious cover sheet.
2) 抗拉强度高：利用SR防渗盖片内加强筋的增强作用，使其抗拉强度达到并超过25px厚橡胶板的强度值，这样既可节约成本，又使得施工更加方便，防渗质量得以保证；
2) High tensile strength: Using the reinforcing effect of reinforcing bars in SR anti-seepage cover sheet, the tensile strength of SR anti-seepage cover sheet can reach and exceed the strength value of 25px thick rubber sheet, which can not only save cost, but also make construction more convenient and guarantee the anti-seepage quality.
3) 抗撕裂、抗冲击性好：由于有加强筋的增强作用，SR防渗盖片具有比纯橡胶片更好的抗撕裂、抗冲击破坏性能；
3) It has good tear resistance and impact resistance: SR impermeable cover sheet has better tear resistance and impact resistance than pure rubber sheet due to the reinforcement effect of reinforcing bars.
4) 与SR塑性止水材料及混凝土面粘结效果好：SR防渗盖片上复合有SR塑性止水材料，可与混凝土基面粘合密封，均匀传递水压力，实现了很好的防渗密封效果；
4) Good bonding effect with SR plastic water-proof material and concrete surface: SR plastic water-proof material is compounded on SR anti-seepage cover sheet, which can be bonded and seaLED with concrete base surface, and can transmit water pressure evenly, thus achieving good anti-seepage sealing effect;
5) 具有粘贴的自愈性：由于SR塑性止水材料具有粘结自愈性，因此SR防渗盖片与混凝土粘结面被拉开后，可重新直接粘贴回去，不影响SR防渗盖片的防渗作用；
5) It has self-healing property of bonding: because SR plastic water-proof material has self-healing property of bonding, the bonding surface between SR impervious cover sheet and concrete can be re-bonded directly after being pulLED apart, without affecting the impervious function of SR impervious cover sheet;
6) 施工简便：SR防渗盖片柔韧性好，与混凝土基面及SR材料鼓包粘贴性好，粘贴密实，可以进行现场冷粘接或热硫化连接，粘结强度高，工序简便，容易施工；
6) Simple construction: SR anti-seepage cover sheet has good flexibility, good adhesion with concrete base and SR material bulging, compact bonding, cold bonding or hot vulcanization bonding on site, high bonding strength, simple process and easy construction;
7)耐老化性好：三元乙丙橡胶是耐候性的橡胶之一，其1.2mm厚防水卷材产品在建筑防水工程上已广泛应用和检验，使用寿命可达50年以上， 3～4mm厚三元乙丙橡胶的耐老化性能更为优异，防渗保护作用也将会更好；
7) Good ageing resistance: EPDM is one of the weatherproof rubber. Its 1.2mm thick waterproof membrane products have been widely used and tested in building waterproofing engineering. Its service life can reach more than 50 years. The ageing resistance of EPDM with 3-4mm thickness is better, and its anti-seepage protection will also be better.
8)易于检查维修：SR防渗盖片在混凝土表面施工后，施工质量易于检查；一旦发生破损，包括在水下部位，也易于修复。
8) Easy to inspect and repair: After SR impervious cover sheet is constructed on concrete surface, the construction quality is easy to inspect; once damage occurs, including underwater parts, it is also easy to repair.
