Root penetration-resistant self-adhesive polymer modified asphalt waterproof coiled material
The invention relates to a root penetration-resistant self-adhesive polymer modified asphalt waterproof coiled material which comprises an upper isolation layer, a base layer and a lower isolation layer, wherein the two surfaces of the base layer are coated with modified asphalt mastic; and the modified asphalt mastic is prepared from the following raw materials in parts by weight: 100-105 parts of petroleum asphalt, 8-12 parts of butadiene styrene rubber, 6-8 parts of SBS, 10-15 parts of modified nano-zinc oxide, 6-8 parts of coumarone resin, 1-2 parts of octyl epoxy stearate, 10-15 parts ofmodified fly ash fiber powder, 3-5 parts of an antioxidant and 1-5 parts of a stabilizer. The specially modified nano-zinc oxide and fly ash fiber powder are added into the modified asphalt used in the waterproof coiled material, so that the waterproof coiled material has excellent root penetration resistance.
本发明涉及一种耐根穿刺自粘聚合物改性沥青防水卷材，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、丁苯橡胶8～12份、SBS6～8份、改性纳米氧化锌10‑15份、古马隆树脂6～8份、环氧硬脂酸辛酯1‑2份、改性粉煤灰纤维粉10～15份、抗氧剂3～5份和稳定剂1～5份。本发明防水卷材使用的改性沥青中加入有经过特殊改性的纳米氧化锌和粉煤灰纤维粉，具有优秀的耐根穿刺性能。
