Root-puncture-resistant asphalt waterproof coiled material
The invention discloses a root-puncture-resistant asphalt waterproof coiled material, which is prepared from the following raw materials in parts by weight: 50-80 parts of petroleum asphalt, 5-10 parts of a waterproof agent, 6-8 parts of a tackifier, 10-15 parts of an anti-aging agent and 5-10 parts of a reinforcing agent. The waterproof agent is prepared by the following steps: adding a monomer pre-emulsion accounting for 1/3 of the total mass, a buffer agent and deionized water into a reaction container for mixing, then adding an APS aqueous solution with the mass fraction of 5% into the reaction container, and then heating to 80 DEG C under the protection of nitrogen; dispersing the residual monomer pre-emulsion accounting for two thirds of the total mass, dropwise adding the monomer pre-emulsion into the reaction container, after dropwise adding, heating to 88 DEG C, carrying out heat preservation reaction for 2 hours, cooling to 35 DEG C, adjusting the pH to 7-8, and filtering to obtain the waterproof agent. The waterproof agent and the reinforcing agent are blended and added into the petroleum asphalt, so that the waterproof performance and the puncture resistance of the asphalt coiled material are greatly improved.
本发明公开了一种耐根穿刺沥青防水卷材，由以下重量份原料组成：50‑80份石油沥青、5‑10份防水剂、6‑8份增粘剂、10‑15份防老剂、5‑10份增强剂；防水剂由以下步骤制成：将总质量三分之一的单体预乳化液、缓冲剂和去离子水加入到反应容器中进行混合，再向反应容器中加入质量分数为5％的APS水溶液，然后在氮气保护下升温至80℃；将剩余总质量三分之二的单体预乳化液进行分散后，滴加到反应容器中，滴加完毕后，升温至88℃，保温反应2h后，降温至35℃调节pH至7‑8，过滤，即得到防水剂；本发明将防水剂和增强剂共混加入到石油沥青中，大大提高了沥青卷材的防水性能和耐穿刺性能。
