Abstract

The invention belongs to environment-friendly glue for construction, and particularly relates to environment-friendly nail-free glue for construction and a preparation method thereof. The nail-free glue comprises the following compositions: 12.0-40.0% of polyvinyl acetate resin, 18.0-40.0% of reinforcing filler, 15.0-40.0% of a solvent, 0.5-8.0% of a thixotropic agent, 0.1-3.5% of a coupling agent, 0.1-5.0% of a plasticizer, and 0.1-0.5% of a dispersing agent. The preparation method comprises the following steps: adding the solvent into a homogenizer, starting the homogenizer, then adding the polyvinyl acetate resin, stirring for 1-3 hours until all the materials are dissolved into a transparent and uniform liquid, further, adding the plasticizer, the coupling agent and the dispersing agent, uniformly stirring, then slowly adding the reinforcing filler, uniformly stirring to prepare a flowing pulpy mixture, then adding the thixotropic agent, and uniformly stirring to prepare the environment-friendly nail-free glue for construction. According to the invention, the environment is protected, the construction is convenient, no nail-holes are bonded, the bonding strength is high, and the ageing resistance is excellent.

Description

technical field [0001] The invention belongs to an environment-friendly adhesive, in particular to an environment-friendly building nail-free glue and a preparation method thereof. Background technique [0002] Construction adhesives can better bond the same and different building materials together, replacing the original nailing, riveting, welding and other processes, which greatly saves resources, improves construction speed, and reduces project costs. In recent years, the value-added range of construction adhesives has far exceeded that of other products, and its application range has also expanded from the single existing building reinforcement, reinforcement, and earthquake resistance to various fields such as roads, bridges, subways, culverts, tunnels, and dams. Even the new high-speed railway projects also use a large number of building structure adhesives, and with the advancement of technology, the adhesives have changed to special functions, such as heat resistanc...
