Masonry structure mortar reinforcing structural adhesive and preparation method thereof
The invention provides a masonry structure mortar reinforcing structural adhesive and a preparation method thereof, solves the problem of high hardening shrinkage rate of repair type mortar in the prior art, and provides the masonry structure mortar reinforcing structural adhesive which has the advantages that the reinforcing structural adhesive and the original part of strength-lost mortar of a masonry jointly act, so that the strength of the masonry structure is greatly improved; the reinforcing structural adhesive comprises cement, fine aggregate, an epoxy resin structural adhesive and an additive, the additive is a mixture of triethylene glycol monomethyl ether and urea, the use amount of the additive is 0.2%-0.3%, and due to the fact that triethylene glycol monomethyl ether serving as a shrinkage reducing agent is added, the hardening shrinkage rate of the cement can be effectively reduced, and the strength of the cement is improved. And the possibility of secondary damage to the masonry structure caused by incompactness of the reinforcing mortar subsequently is effectively reduced.
本发明提出了一种砌体结构砂浆补强结构胶及其制备方法，解决了现有技术中修复型砂浆硬化收缩率高的问题，一种砌体结构砂浆补强结构胶，所述补强结构胶与砌体原有部分失强的砂浆共同作用，所述补强结构胶包括水泥、细骨料、环氧树脂结构胶、外加剂，所述外加剂为三甘醇单甲醚与尿素的混合物，用量为0.2%~0.3%，由于加入了作为减缩剂的三甘醇单甲醚，可以有效的降低水泥的硬化收缩率，有效降低了后续因补强砂浆不致密而导致砌体结构二次破坏的可能。
