Moisture-curing liquid waterproof repair liquid for brick-smashing-free leaking stoppage
The invention discloses a moisture-curing liquid waterproof repair liquid (C) for brick-smashing-free leaking stoppage. The repair liquid comprises an alkoxysilane-modified polymer (A); a catalyst selected from a catalyst (C1) comprising a metal-containing catalyst, guanidine and imidazole, and a catalyst (C2) comprising a unit of formula (II); and a reactive diluent (D) having the structure of Formula (III). The formula (I) is P1-[(CR<2><1>)a-Si(OR2)bR<3-b><3>]c; the formula (II) is BfSi(OR4)dR<5>O<(4-f-d-e)/2>; and the formula (III) is R8-[Si(OR6)gR<3-g><7>]h. The moisture-curable liquidwaterproof composition (C) has low viscosity and high reaction activity, can permeate along ceramic tile gaps, pipeline peripheral gaps and the like, and is integrally hydrolyzed, cross-linked and cured into an elastomer after meeting water, so that waterproof leaking stoppage without brick smashing is performed, and the repair liquid is used for waterproof repair in indoor kitchens and bathrooms,repair of roof waterproof materials and the like.
本发明公开了一种免砸砖堵漏的湿固化液体防水修复液(C)，包含：烷氧基硅烷改性聚合物(A)、选自含金属催化剂、胍和咪的催化剂(C1)以及包含式(II)单元的催化剂(C2)，还可包含具有式(III)结构的活性稀释剂(D)：P‑[(CR)‑Si(OR)R](I)BSi(OR)RO(II)R‑[Si(OR)R](III)该湿固化液体防水组合物(C)具有低粘度、高反应活性，可以顺着瓷砖缝隙、管道周边缝隙、等渗入，在遇到水分后整体水解交联固化为弹性体，从而进行免砸砖的防水堵漏，用于室内厨卫中防水修缮、屋顶防水材料的修缮等。
