Example Embodiment

[0034] Example 1:

[0035] High temperature resistant powder coating, including the following weight ratio ingredients: modified resin 400-600, cross-linkage curing agent 20-30, mica powder 100-200, talc powder 150-250, hollow fine powder 100-200, defoamer 1 -9, graft 1-9, high temperature pigment 20-30, other auxiliaries 1-3.

[0036] The talc is a fine grade, a particle size of 4.5-5.5 μm, and the mica powder is a white-female powder having a particle diameter of 15-17 μm.

[0037] With the modified resin as the main filler, the mica powder, talc powder is added, and the heat resistance and adhesion performance, while the use of auxiliaries, leveling agents, cross-linkage curing agents can be guaranteed. The reliable production of coatings is carried out to ensure the quality of the preparation. On the basis of the above-mentioned hollow fine powder, the flow performance of the coating is increased, thereby reducing the molten extrusion during the preparation and the difficulty ...

[0038] Example 2:

[0039] High temperature resistant powder coating, including the following weight ratio ingredients: modified resin 400-600, cross-linkage curing agent 20-30, mica powder 100-200, talc powder 150-250, hollow fine powder 100-200, defoamer 1 -9, leveling agent 1-9, high temperature pigment 20-30, other auxiliaries 1-3, modified silicon carbide 5-7, modified silica sol 20-30.

[0040] The talc is a fine grade, a particle size of 4.5-5.5 μm, and the mica powder is a white-female powder having a particle diameter of 15-17 μm.

[0041] On the basis of Example 1, the modified silicon carbide and modified silica sol were increased, but also increased significantly on the acid-resistant corrosion resistance of powder coatings, but also increased the adhesion of the powder coating.

Example Embodiment

[0042] Example 3:

[0043] A high temperature resistant powder coating comprising the following weight ratio component: modified resin 450-550, cross-linkage curing agent 22-28, mica powder 120-180, talc powder 180-220, hollow micro powder 120-180, defoamer 3 -7, level 3-7, high temperature pigment 20-30, other auxiliaries 1-3, modified silicon carbide 6, modified silicon sol 15.

[0044] The talc is a fine grade, a particle size of 4.5-5.5 μm, and the mica powder is a white-female powder having a particle diameter of 15-17 μm.

Abstract

The invention discloses a high-temperature-resistant powder coating, and relates to the technical field of powder coatings. Comprising the following components: modified resin, a cross-linking curing agent, mica powder, talcum powder, hollow micro powder, a defoaming agent, a flatting agent, high-temperature pigment and other auxiliaries, and the preparation method specifically comprises the following steps: premixing the raw materials in proportion, and then putting the raw materials into a stirrer for dry stirring. The modified resin is used as a main filler, the mica powder and the talcum powder are added on the basis of the modified resin, heat resistance and adhesion performance are guaranteed, meanwhile, by means of the defoaming agent, the flatting agent, the crosslinking curing agent and other auxiliaries, reliable preparation of the coating can be guaranteed, preparation quality is guaranteed, on the basis, the hollow micro powder is added, the flowing property of the coating is improved, and the coating is more environment-friendly. Therefore, the difficulty of melt extrusion in the preparation process and the difficulty of the subsequent spraying process are reduced, and the heat resistance of the coating is also well improved due to the increase of the hollow micro powder.
