Waterproof adhesive for wet-laid waterproof coiled material and preparation method of waterproof adhesive
The invention relates to the field of waterproof materials, in particular to a waterproof adhesive for a wet-laid waterproof roll and a preparation method of the waterproof adhesive, and aims to solve the problems that a capillary structure is blocked by polymer components in a polymer cement adhesive, bubbles doped in mortar added with a surfactant cannot be discharged in time, adhesion defects are formed, and the anti-stripping strength is poor. Portland cement, quartz sand, water, a surfactant, long-chain polyatomic acid, cellulose ester, cellulose ether, vinyl acetate and water-absorbent resin coated particles form a new adhesive layer, so that multiple isolation of water is realized; according to the present invention, the pressure of the capillary action during the curing of the cement mortar adhesive can be reduced, the crack generation is avoided, the bubble discharge cannot be hindered, the secondary waterproof layer can be formed after the crack damage is generated, and the secondary adhesion strength and the high peeling strength are provided.
本发明涉及防水材料领域，具体为一种湿铺防水卷材防水粘结剂及其制备方法，为解决聚合物水泥胶粘剂中存在的聚合物成分堵塞毛细管结构，添加有表面活性剂的砂浆中掺入气泡无法及时排出，形成粘贴缺陷，抗剥离强度较差的问题，由硅酸盐水泥、石英砂、水、表面活性剂、长链多元酸、纤维素酯、纤维素醚、醋酸乙烯酯、吸水树脂包覆颗粒组成新的胶粘剂层，实现对水分的多重隔绝；本申请能够减少水泥砂浆胶粘剂固化中毛细管作用的压力，避免了裂缝生成，不会阻碍气泡排出，且能够在裂缝破损产生后形成二次防水层，具有二次粘连强度以及较高的抗剥离强度。
