Abstract

The invention discloses an environment-friendly and anticorrosive graphene coating material for a bridge metal member, and a preparation method of the environment-friendly and anticorrosive graphene coating material. The coating material is prepared from a component A and a component B; the component A is prepared from epoxy polysiloxane resin, 3-aminopropyl trimethoxy silane, graphene, ultrafine rutile titanium dioxide, fumed silica, a dispersant, a defoamer, a flatting agent, a thickener and a film formation agent; the component B is prepared from triethoxy ethyl silane, triethoxy propyl silane and anacardol; finally the environment-friendly and anticorrosive graphene coating material is prepared according to a ratio of the component A to the component B. The preparation method of the environment-friendly and anticorrosive graphene coating material for a bridge metal member comprises the following process steps: step 1: performing a production process of the component A; step 2: performing a production process of the component B; step 3: making a finished product of the environment-friendly and anticorrosive graphene coating material. The coating material is used for protecting the bridge metal member, has low surface tension, aging resistance, water resistance, flexibility, saline water resistance and corrosion resistance, and can be widely applied to bridge metal member protection.

Description

technical field [0001] The invention relates to a graphene environment-friendly anticorrosion paint for bridge metal components, which can be widely used in the protection of bridge metal components. Background technique [0002] Metal components of bridges are susceptible to aging or corrosion of metal components and their coatings due to temperature differences, sun exposure, ultraviolet rays, moisture, acid rain, salt spray and other factors, requiring protective agents. However, at present, the metal components of the bridge are generally exposed without any reliable protection, and the service life of the bridge metal components is short, which seriously affects the safety of the bridge. Contents of the invention [0003] The object of the present invention is to provide a kind of bridge metal member protection, low surface tension, aging resistance, water resistance, flexibility, salt water resistance and anti-corrosion graphene environment-friendly anticorrosion coa...
