Abstract

The invention discloses a metal-to-metal adhesive with a stable size. The metal-to-metal adhesive comprises the following raw materials: water-borne epoxy resin, deionized water, triethylene tetramine, phthalic anhydride, isopropyl trititanate, nanometer calcium carbonate, fatty alcohol polyoxyethylene ether, isophorone, dibutyltin dilaurate and polypropylene polyoxyethylene glycerol ether. The metal-to-metal adhesive with a stable size in the invention is simple to prepare and has a stable cured size, good bonding performance, water resistance and corrosion resistance; since the water-borne epoxy resin is used as a main raw material, the metal-to-metal adhesive has good hardness, elasticity and weatherability; since water is used as a solvent, the environment is protected, and cost is reduced; the modified nanometer calcium carbonate enables the adhesive to be uniformly dispersed and to maintain rheological properties and certain viscosity; the dibutyltin dilaurate allows the drying time of the adhesive to be shortened, the adhesive to be saved, work efficiency to be improved, and cost to be reduced; and due to addition of normal temperature and high temperature curing agents, the adhesive can be stored at 4 DEG C, has long shelf life, exerts curing effect in different environments and has a wide application scope.

Description

technical field [0001] The invention relates to a dimensionally stable metal adhesive, which belongs to the field of metal adhesives. Background technique [0002] Adhesive refers to a kind of natural or synthetic, organic or inorganic substances that can connect two or more parts or materials together through the adhesion and cohesion of the interface, collectively referred to as glue. Adhesives, also known as adhesives, are customarily referred to as "glue". In short, an adhesive is a substance that can bind adherends together through bonding. With the development of industry, metal adhesives require more and more space. However, many metal adhesives on the market have poor weather resistance, are greatly affected by ambient temperature, have weak adhesion, and unstable curing dimensions. The drying time is long, resulting in waste of adhesive. [0003] Epoxy resin adhesive has high bonding strength, high hardness, good rigidity, acid, alkali, oil and organic solution r...
