AI Technical Summary

Problems solved by technology

As a heavy anti-corrosion epoxy resin coating, the coating has poor weather resistance and is easy to pulverize; at higher temperatures, the ability to withstand strong corrosive media is poor
Silicone resin coatings have better temperature resistance and weather resistance, but they need to be baked and cured at high temperature during the film forming process, which increases construction costs and causes energy waste.

Abstract

The invention provides low-temperature curing temperature-resistant heavy-duty anticorrosive paint, which comprises a component A and a component B, wherein the component A takes epoxy modified silicone resin as main raw material combined with other pigment fillers and additives; the component B is modified polyamide; and the component A and the component B in use are mixed in a certain ratio. The low-temperature curing temperature-resistant heavy-duty anticorrosive paint is characterized in: 1, two components cured to be film at low temperature, no need for high-temperature baking, simple convenient construction, cost saving and capability of resisting a high temperature of 200 DEG C for a long period of time; 2, excellent physical and mechanical properties, adhesion, good flexibility and high anti-impact strength; and 3, excellent chemical stability, boiling resistance, oil resistance and anti-aging performance.

Description

technical field [0001] The invention relates to a temperature-resistant and anti-corrosion coating for the inner and outer walls of oil pipelines in oil fields, in particular to a low-temperature curing temperature-resistant heavy-duty anti-corrosion coating. Background technique [0002] The anti-corrosion coatings on the inner and outer walls of existing oil pipelines in oil fields are mainly epoxy resin coatings or silicone resin coatings. As a heavy anti-corrosion epoxy resin coating, the coating has poor weather resistance and is easy to pulverize; at higher temperatures, the ability to withstand strong corrosive media is poor. Silicone resin coatings have better temperature resistance and weather resistance, but they need to be baked and cured at high temperature during the film forming process, which increases construction costs and causes energy waste. Contents of the invention [0003] The purpose of the present invention is to provide a coating that can withstan...
