Thick-coated epoxy thermal insulation and anticorrosion paint

Abstract

The invention discloses thick-layered thermal-insulated anticorrosion epoxy paint.The thick-layered thermal-insulated anticorrosion epoxy paint comprises a component A and a component B, wherein the component A comprises 32-45% of modified epoxy resin, 7-13% of solvent, 0.4-0.5% of thixotropic agent, 0.5-0.6% of defoamer, 6-8% of titanium dioxide, 0.4-0.2% of carbon black, 15-25% of talcum powder, 0.8-1.0% of silane coupling agent, 18-23% of hollow glass microspheres and 2-2.7% of basalt fibers, the component B refers to 100% of modified polyamide resin, and before application, the component A and the component B are mixed to use according to a weight ratio of 83-88 to 12-17.The thick-layered thermal-insulated anticorrosion epoxy paint has the advantages that a high-temperature-resistant coating film can be combined with the thermal-insulated hollow glass microspheres and the flaky talcum powder, so that an obtained coating is excellent in high-temperature-resistant performance and thermal-insulated performance; the thick-layered thermal-insulated anticorrosion epoxy paint has excellent long-term anticorrosion performance and is capable of effectively preventing metal surface corrosion from permeation of rainwater, fog and electrolyte ions; the thick-layered thermal-insulated anticorrosion epoxy paint is easy to prepare and simple and convenient to apply and can be widely applied to the fields of the petrochemical industry and heating pipelines.

Description

technical field [0001] The invention relates to the technical field of paint research and preparation, relates to the petrochemical industry and a protective paint capable of preserving heat for steel structures and having an anti-corrosion effect. Background technique [0002] The worldwide energy crisis has promoted the research and development of energy-saving technology, and the energy-saving technology has promoted the general application of thermal insulation technology in the petrochemical industry and thermal pipelines. The function of the thermal pipeline insulation layer is to block the loss of heat flow, and most of the insulation materials used are processed by mineral calcination and then bonded. Because minerals contain a large amount of inorganic salts, thermal insulation materials made of minerals still contain a large amount of corrosive substances such as chlorides and sulfides; on the other hand, the thermal insulation materials are usually porous structur...

AI Technical Summary

Problems solved by technology

The implementation of anti-corrosion and thermal insulation projects is relatively complicated, not only the progress is slow, but the labor cost is also high

In addition, due to the inevitable leaks and gaps in the assembly and connection of pipelines, it is easy to cause rainwater to infiltrate, which leaves hidden dangers for the corrosion of metal pipelines under the insulation layer.
