Environment-friendly root-puncture-resistant modified asphalt waterproof coiled material and preparation method thereof
The invention relates to an environment-friendly root-puncture-resistant modified asphalt waterproof coiled material and a preparation method thereof. The waterproof coiled material comprises an upper isolating layer, a tire base layer and a lower isolating layer, wherein both surfaces of the tire base layer are coated with modified asphalt mastic; the modified asphalt mastic is prepared from the following raw materials in parts by weight: 100-105 parts of petroleum asphalt, 6-10 parts of naphthenic oil, 6-8 parts of SBS, 5-8 parts of nitrile rubber, 20-30 parts of modified serpentine powder, 1-3 parts of ammonium polyphosphate, 2-5 parts of polyvinyl alcohol and 3-5 parts of an antioxidant. The preparation method comprises the following steps: sequentially adding the raw materials into a reaction kettle, uniformly stirring to obtain a modified asphalt material, conveying the modified asphalt material into an oil immersion tank, spreading a middle tire body layer into an oil immersion layer, coating the front and back surfaces of a tire base layer with modified asphalt layers with required thicknesses, cooling, and respectively coating the outer surfaces of the modified asphalt layers with isolation layers, and preparing the modified asphalt waterproof coiled material. The waterproof coiled material has excellent tensile resistance and root puncture resistance, and can meet the root puncture resistance requirement of the waterproof coiled material in JC/T1075-2008.
本发明涉及一种环保型耐根穿刺改性沥青防水卷材及其制备方法，防水卷材包括上隔离层、两面均涂覆有改性沥青胶的胎基层和下隔离层，改性沥青胶由以下重量份数的原料制成：石油沥青100～105份、环烷油6～10份、SBS6～8份、丁腈橡胶5‑8份、改性蛇纹石粉20‑30份、聚磷酸铵1‑3份、聚乙烯醇2‑5份以及抗氧剂3～5份。将各原料按顺序依次加入反应釜中，搅拌均匀后得到改性沥青料，将改性沥青料输送至浸油槽，中间胎体层展开至浸油层内，将胎基层的正反两面涂布所需厚度的改性沥青层，冷却后，在改性沥青层的外表面分别涂覆隔离层，制得改性沥青防水卷材。本发明的防水卷材具有优良的耐拉伸性能以及耐根穿刺性能，能够满足JC/T1075‑2008中对于防水卷材耐根穿刺的要求。
