Embodiment

[0042] Example: A heavy-duty anti-corrosion heat-insulating and static-conductive coating: using acrylic modified epoxy resin as the base material, using reactive and non-reactive diluents as solvents, and using liquid polysulfide rubber as a toughening agent, in functional pigments and fillers Prepare component A with the cooperation of auxiliary agents; use modified amine synthesized from cashew nut shell liquid as curing agent, and form component B with the cooperation of accelerator and hydrophilic agent. After mixing components A and B at a weight ratio of 2:1 , formulated into a two-component heavy-duty anti-corrosion, heat-insulating, and static-conductive coating: the composition of each component in the formula is as follows, of which component A is:

[0043] Modified epoxy resin BYD-7201 40%

[0044] Polysulfide rubber JLY-121 2%

[0045] Reactive diluent 6286 5%

[0046] Non-reactive diluent NX-2020 10%

[0047] Ultrafine silica-alumina-based hollow microspheres ...

Abstract

The invention discloses a heavy corrosion resistant, heat insulating and static conductive coating, which is prepared by the following steps of: dissolving acrylic acid modified epoxy resin which is taken as a substrate into active and inactive diluents in a way of taking liquid polysulfide rubber as a toughening agent in the presence of a functional pigment and an aid to prepare a first component; preparing a second component in a way of taking cashew nut shell liquid-synthesized modified amine as a curing agent under the cooperation of an accelerator and a hydrophilic agent; and mixing the first and second components in the weight ratio of 2:1. The heavy corrosion resistant, heat insulating and static conductive coating has the characteristics of no solvent, high adhesive power, high static conductivity, heavy corrosion resistance, high heat-insulating property, environmental friendliness, non-toxicity, wet rusty thick coating capability, great coating cost reduction, and applicability to the corrosion-resistant coating of inner and outer walls of large oil tanks, ballast tanks of ships, offshore drilling platforms, bridges, open petrochemical equipment, ships, high-speed trains and the like.

Description

[0001] Field of invention [0002] The invention relates to the technical field of metal surface coatings, in particular to a heavy-duty anti-corrosion, heat-insulating, and static-conducting coating. Background technique [0003] With the progress of society, the development of anti-corrosion coatings and coating technology pays more attention to the comprehensive balance of "environmental protection, safety, performance and cost". Environmental protection and safety are the prerequisites for the development of the anticorrosion industry. High performance, multi-function and low cost are the goals pursued by the anticorrosion industry. In the total cost of anti-corrosion engineering, coating cost accounts for 15-30%, and coating cost accounts for 70-85%. Coating cost includes substrate surface treatment cost, time cost, environmental cost, waste disposal cost, safety program cost, etc. If static electricity is generated on the metal surface of petrochemical equipment, ships ...
