Embodiment Construction
[0030] The formula (weight unit is gram) of 10 embodiments has been listed in table 1, and its preparation method is all: at normal temperature, kaolin, zircon quartz, silicon carbide, porcelain powder, asbestos powder, graphite powder of batching amount are first mixed Grind in a high-energy mill for 50-100 minutes, and then finely sieve the large-sized mixed powder for 50-80 minutes to make the particle size reach 20-200nm. Then mix the twice-ground powder and solid powder such as nano-aluminum powder, nano-alumina, nano-quartz powder, pigments and fillers with epoxy resin, BYK dispersant, BYK leveling agent, mixed organic solvents and other substances Mix the liquid components in the formula, fully disperse and stir evenly; then filter, pack and seal.

Abstract
A cermet anti-corrosion coating, its formula mainly includes: kaolin, nano-aluminum powder, nano-alumina, silicon carbide, nano-quartz powder, porcelain powder, asbestos powder, graphite powder, pigments and fillers, epoxy resin, additives, mixed organic Solvents, etc., the solid powder is treated by nanometer ultra-fine processing, so that the particle size can reach 20-200nm. The paint of the invention is a one-component paint, and the manufacturing process is simple, economical and environmentally friendly. The paint coating does not need a primer, and can be used alone without a special topcoat. The coating has excellent wear resistance, corrosion resistance, impact resistance and stability. The coating has strong adhesion, dense and stable, and can effectively insulate Acid, alkali, salt, seawater erosion. It can be widely used in oil pipelines, oil storage tanks and chemical equipment, ships, bridges, offshore platforms and other steel structures.
Description
technical field [0001] The invention relates to a paint, in particular to a cermet anticorrosion paint and a preparation method thereof. Background technique [0002] Traditional long-term heavy-duty anti-corrosion coatings have either-or problems in terms of environmental protection, production, cost, use, anti-corrosion, stability and temperature resistance, etc., that is, there are environmental problems, or economic problems, or inconvenient production and use, etc. problems, and cannot simultaneously have properties such as corrosion resistance, stability, high temperature resistance, wear resistance and pressure resistance. Contents of the invention [0003] The purpose of the present invention is to provide a cermet anti-corrosion coating and its production method, which are environmentally friendly, economical, convenient to manufacture and use, and have excellent corrosion resistance, stability, high temperature resistance, wear resistance, pressure resistance and...
