Embodiment 1

[0026] Example 1: Modified epoxy resin KD190 28.27%, modified amine curing agent ZP0084215.12%, pigment 32.58%, toughening agent NC513 3.12%, anti-settling agent organic bentonite 2.36%, mixed solvent 18.55%. The component content of the pigment is calculated by weight percent: 40-60% mica powder, 20-40% talcum powder and 10-30% barium sulfate. The weight ratio of xylene to n-butanol in the mixed solvent is 2:1.

Embodiment 2

[0027] Example 2: Modified epoxy resin KD19032.46%, modified amine curing agent ZP0084217.21%, pigment 29.45%, toughening agent LITE2513HP4.08%, anti-settling agent fumed silica 1.88%, mixed solvent 14.92% . The component content of the pigment is calculated by weight percent: 40-60% mica powder, 20-40% talcum powder and 10-30% barium sulfate. The weight ratio of trimethylbenzene and isopropanol in the mixed solvent is 2:1.

Embodiment 3

[0028] The influence of embodiment 3 different epoxy resins on paint film performance

[0029] The type of epoxy resin was changed, and the composition and content of other components of the high-solid epoxy paint were the same as in Example 1. The influence of different epoxy resins on the performance of the paint film was investigated. The results are shown in Table 1.

Abstract

The invention relates to high-firmness epoxy paint. The high-firmness epoxy paint comprise the following components in a formula by weight percent: 28.27-32.46% of modified epoxy resin, 15.12-17.21% of modified amine hardener, 32.58-29.45% of pigment, 3.12%-4.08% of flexibilizer, 2.36-1.88% of anti-settling agent and 18.55%-14.92% of solvent. The high-firmness epoxy pain solves the problems that the existing thick anticorrosive paint film on a sewer line and a sewage conduit has poor adhesive force, hot water resistance and hot and cold alternation resistance.

Description

technical field [0001] The invention relates to a coating paint used on sewage pipelines, in particular to a formula of high-performance high-solid epoxy paint used for sewage pipelines, a preparation method and a construction method thereof. Background technique [0002] In recent years, with the development of the urban construction industry, the sewer and sewage pipeline industries have also developed rapidly, especially the cast iron pipeline industry has been booming in China in recent years, followed by the anti-corrosion of pipelines The requirements are also getting higher and higher. Since sewer pipes and sewage pipes are buried underground or in buildings, it is not easy to maintain and replace them. Therefore, the anti-corrosion period of the pipes is required to be long, generally 20-50 years, and the sewage discharged from the sewer pipes often contains acid, Alkaline and detergent and other chemical substances, and also withstand the immersion corrosion of hig...
