Most of the interior decoration works of modern buildings adopt a bonding method, which can simply bond various materials on the concrete surface or bond the decoration plates on the surfaces of different materials. The most common adhesive used in the interior decoration engineering of buildings is solvent-type neoprene adhesive (commonly called "all-purpose adhesive"). Typical applications of the universal glue on buildings are as follows: the decorative board, the gypsum board, the heat insulating material and the like are stuck on a ceiling or a cement wall surface, and the ceramic tile, the lacquer cloth substrate, the plastic floor, the window frame and other sealing adhesion are stuck.
The general preparation process of the universal glue is to dissolve plasticated or mixed chloroprene rubber in solvents such as toluene and the like, and then to add pre-reacted tackifying resin and other auxiliary agents to prepare the universal glue, and the volatilization of the components can bring harm to the environment and the human health in use. In addition, when the conventional all-purpose adhesive is used in an environment of 5 ℃ or lower, the adhesive property is deteriorated, and thus the conventional all-purpose adhesive is not suitable for use in a low-temperature environment. In conclusion, the development of the low-temperature-resistant environment-friendly all-purpose adhesive has important significance.
