Abstract

The invention discloses an adhering cement adhesive for connecting parts of a prefabricated concrete pipe corridor. The adhering cement adhesive comprises a derusting layer, a waterproof layer and ananti-radiation layer, wherein the derusting layer comprises silicate cement and a derusting agent; the waterproof layer comprises silicate cement and a waterproof agent; the anti-radiation layer comprises silicate cement and an anti-radiation agent; the weight ratio of the derusting agent or the waterproof agent or the anti-radiation agent to the silicate cement is 1:(1.2 to 1.5). The adhering cement adhesive has the advantages that the contact between water and metal surface layer is prevented, so that the acid-resistant, alkaline-resistant and salt-resistant properties are realized; by adopting the chelating type, and containing the anti-radiation layer, the purpose of longer-time corrosion protection is realized; by adopting the inorganic material, the toxicity and odor are avoided, thefireproof property is realized, the construction is simple, and the safe and environment-friendly effects are realized; the adhering cement adhesive is suitable for various environments.

Description

technical field [0001] The invention relates to the field of metal coatings, in particular to a bonding cement glue used for joints of prefabricated concrete pipe galleries. Background technique [0002] Steel structures such as steel-frame buildings or steel-frame bridges are premised on long-term use. Therefore, these steel structures have been given surface coating for the purpose of ensuring corrosion resistance and aesthetics. Generally, the coating consists of a base coat for rust resistance, a top coat for ensuring weather resistance and aesthetics, and an intermediate coat for improving the adhesion between the base coat and the top coat. The coating consists of three layers. The coating life is greatly affected by the coating material and the use environment, but in a more severe environment, there are also modified epoxy-based coatings with a coating life of 6 years, and epoxy-urethane-based coatings with a coating life of 6 years. For 10 years such an example. ...
