实施例2
一种水管用胶粘剂的制备方法，所述制备方法包括：将100g阿拉伯树胶、40g海藻酸钠、30g酚醛树脂、20g醇酸树脂和10g聚氯乙烯搅拌混合（搅拌速度为200rmp，时间为10min）后形成基础混合液M；将所述基础混合液M加热至35℃，并将其与8g白炭黑（比表面积为165m/g）、3g乳化剂和5g稳定剂混合后制得所述水管用胶粘剂A2。
实施例3
一种水管用胶粘剂的制备方法，所述制备方法包括：将100g阿拉伯树胶、30g海藻酸钠、25g酚醛树脂、15g醇酸树脂和8g聚氯乙烯搅拌混合（搅拌速度为150rmp，时间为6min）后形成基础混合液M；将所述基础混合液M加热至32℃，并将其与5g白炭黑（比表面积为150m/g）、2g乳化剂和3g稳定剂混合后制得所述水管用胶粘剂A3。
对比例1
一种水管用胶粘剂的制备方法，所述制备方法包括：将100g阿拉伯树胶、10g海藻酸钠、10g酚醛树脂、5g醇酸树脂和3g聚氯乙烯搅拌混合（搅拌速度为80rmp，时间为3min）后形成基础混合液M；将所述基础混合液M加热至25℃，并将其与1g白炭黑（比表面积为130m/g）、0.5g乳化剂和1g稳定剂混合后制得所述水管用胶粘剂D1。
对比例2
一种水管用胶粘剂的制备方法，所述制备方法包括：将100g阿拉伯树胶、50g海藻酸钠、40g酚醛树脂、30g醇酸树脂和15g聚氯乙烯搅拌混合（搅拌速度为250rmp，时间为15min）后形成基础混合液M；将所述基础混合液M加热至40℃，并将其与10g白炭黑（比表面积为170m/g）、5g乳化剂和7g稳定剂混合后制得所述水管用胶粘剂D2。
表1
| 实施例编号 | 粘接强度（MPa） | 水压爆破强度（MPa） |
