High temperature resistant anticorrosive paint and preparation technology thereof

Abstract

The invention discloses a high temperature resistant anticorrosive paint which comprises a main agent and a curing agent, wherein the main agent comprises novolac epoxy resin F-51, diluent, a pigment filler and an auxiliary agent; the invention also disclosed a preparation technology of the paint, and the method comprises the following steps of: blending, grinding, mixing and the like. The high temperature resistant anticorrosive paint is used for solving the problems of high temperature resistance and anticorrosion after long-term immersion of a pipeline or a hot water tank in the boiling water environment, and the inner wall coating formed by the paint is high temperature resistant, high in corrosion resistance, thick in coating and good in flexibility; meanwhile, the high temperature resistant anticorrosive paint can be cured at the room temperature, has no special requirements for the construction environment and technology, has no strict requirements for the treatment of the surface of a metal substrate, and is good in construction performance, thus greatly lowering the construction cost and being widely applied to the inner walls of various heat accumulation tanks and hot water pipelines.

Description

technical field [0001] The invention belongs to the technical field of production and manufacture of industrial coatings, in particular to a heat-resistant and anti-corrosion coating and a preparation process thereof. Background technique [0002] Most of the large-scale high-temperature liquid storage tanks or pipelines in my country currently use metal pipes, such as carbon steel and stainless steel. Generally, linings are added to the inner walls of these tanks and pipes or paints are directly painted on the inner walls to improve the high temperature resistance and corrosion resistance of these equipment and prolong their service life. Stainless steel or carbon steel tanks or inner walls of pipes are often protected by composite materials, but the process is complicated, the cost is high, and the popularity is low. At present, it is more common to use suitable coatings on the inner wall surface Form a protective coating, this kind of measure is simple and effective to i...

AI Technical Summary

Problems solved by technology

[0004] However, the currently used phenolic epoxy coatings still have some deficiencies: for example, it is difficult to cure at room temperature, which increases the difficulty of construction; the formed coating film is thin, hard and brittle, and has poor flexibility. Medium, thin paint film, easy to soften, poor water resistance, etc.
