Damp-proof waterproof binder for building and preparation method of damp-proof waterproof binder

Abstract

The invention discloses a damp-proof waterproof binder for a building and a preparation method of the damp-proof waterproof binder. The damp-proof waterproof binder is prepared by adopting the following raw materials in part by weight: 80 to 120 parts of ordinary silicate cement, 24 to 38 parts of condensed silica fume, 4 to 8 parts of poly(hydroxyethyl methacrylate), 18 to 26 parts of zirconium silica residue powder, 1 to 3 parts of toluene diisocynate, 0.2 to 0.4 parts of myristyl glucoside, 5 to 10 parts of ardealite, 12 to 18 parts of polyvinyl alcohol, 10 to 15 parts of yellow dextrin, 3 to 5 parts of methyl hydrogen silicone oil, 25 to 35 parts of acetic styrene-acrylic emulsion, 5 to 10 parts of dry sludge powder, 6 to 12 parts of aluminum silicate, 3 to 6 parts of carboxymethylcellulose, 4 to 7 parts of sodium alginate, 3 to 5 parts of nano zirconium boride, 0.3 to 0.5 parts of dodecyl phosphate betaine, 0.2 to 0.4 parts of glycerol monolaurate, 8 to 14 parts of enhancer and an appropriate amount of water. On the basis of excellent damp-proof waterproof performance, the damp-proof waterproof binder for the building is non-toxic, has no organic volatile matter and is harmless to a human body, pollution-free to the environment and high in cohesive force with various base bodies; compared with ordinary cement mortar, the binding strength is greatly improved, no fracture is caused after the binder is used for a long time, and duration can be realized.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a moisture-proof and water-resistant adhesive for construction and a preparation method thereof. Background technique [0002] The binder is the guarantee of the bonding strength between the abrasive and the matrix. With the development of the chemical industry, various new binders have entered the field of coated abrasives, which has improved the performance of coated abrasives and promoted the development of the coated abrasives industry. In addition to the glue, the adhesive also includes auxiliary components such as solvents, curing agents, toughening agents, preservatives, colorants, and defoamers. Binders include synthetic resins, rubber, and paint, in addition to the most commonly used animal glue. [0003] At present, in the field of construction, the adhesives used for bonding between wood, stone, concrete, ceramics, glass, foam plastics, and metals are mainly chloro...

Problems solved by technology

This kind of adhesive has the following disadvantages. First, during the construction process, the curing speed is slow, which will affect the construction progress; second, the water resistance is poor, and it is easy to crack with water.
