Abstract

The invention discloses an environment-friendly structural adhesive for a wall decorative plate and a preparation method thereof. The environment-friendly structural adhesive comprises a component A and a component B. The component A comprises the following raw materials in parts by weight: 20-30 parts of bisphenol A epoxy resin, 1-3 parts of an antioxidant, 0.5-1.5 parts of a plasticizer, 0.5-2 parts of carbon nanofibers and 1-2 parts of montmorillonite. The component B is prepared from the following raw materials in parts by weight: 3-5 parts of trimethyl hexamethylene diamine and 3-5 parts of dihexyltriamine. An intermediate 2 and cyanuric chloride react to prepare an intermediate 5, the intermediate 5 is oxidized with potassium permanganate to prepare an intermediate 6, the intermediate 6 and an intermediate 4 are subjected to dehydration condensation to prepare an antioxidant, the antioxidant contains a large number of sulfur atoms, the sulfur atoms are easily oxidized into sulfoxide and sulfoxide compounds, so that the structural adhesive has certain oxidation resistance, and meanwhile, due to a large number of hindered phenol structures, the oxidation resistance of the structural adhesive is further improved.

Description

technical field [0001] The invention relates to the technical field of structural adhesive preparation, in particular to an environmentally friendly structural adhesive for wall decorative panels and a preparation method thereof. Background technique [0002] Structural adhesives, referred to as structural adhesives, generally refer to the components used to bond the body under stress, and are adhesives that require relatively high mechanical strength (especially impact peel strength) and durability. It is generally used for structural bonding of stressed parts such as tension, shear, impact and vibration. It has the advantages of high strength, anti-stripping, impact resistance, and simple construction technology. It is used in aerospace, rail vehicles, ships, automobiles, It has a wide range of applications in the field of decoration. [0003] After being used for a period of time, the strength of the existing structural adhesive is reduced due to oxidation, which makes t...
