Examples
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.
