Coating for ancient building repair and preparation method thereof

Abstract

The invention relates to the field of ancient building repair, and particularly discloses a coating for ancient building repair and a preparation method thereof. The coating for ancient building repair is prepared from the following components: a pigment, styrene-acrylic emulsion, silicone acrylic emulsion, nano tourmaline powder, a coalescing agent, filler, a thickening agent, a pH regulator and a defoaming agent. The preparation method comprises the following steps: (1) mixing the pigment, the filler and the nano tourmaline powder, and uniformly stirring to obtain a pre-mixture; (2) uniformly mixing the pre-mixture with a part of silicone acrylic emulsion, grinding and dispersing to obtain a pigment color paste; and (3) adding the rest of the silicone acrylic emulsion, styrene-acrylic emulsion, the coalescing agent and the pH regulator into the pigment color paste, uniformly stirring, then adding the thickening agent, and uniformly stirring to obtain the coating for ancient building repair. The coating disclosed by the invention has the advantage of relatively good external environment corrosion resistance; in addition, the preparation method provided by the invention has the advantage that all the components are mixed more uniformly.

Description

technical field [0001] The application relates to the field of restoration of ancient buildings, more specifically, it relates to a coating for restoration of ancient buildings and a preparation method thereof. Background technique [0002] my country's ancient buildings have a long history, unique structures, exquisite craftsmanship and profound cultural connotations, and occupy an important position in the material cultural heritage. However, ancient buildings are easily damaged or even destroyed by natural or human factors. In order to better protect those The ancient buildings left behind make them last for a long time, and we need to continue to maintain the existing ancient buildings. [0003] Buildings with wooden structures as the main body are the mainstream of ancient buildings in my country, and they are also important objects for the maintenance of ancient buildings today.

AI Technical Summary

Problems solved by technology

[0004] Ancient buildings with wooden structures are easily corroded under the action of external environments such as moisture or mold. In the prior art, coatings are usually applied to the surface of ancient buildings to better protect ancient buildings. However, in the prior art The coating in the coating is not good at resisting the corrosion of the external environment, and it is difficult to have a continuous protective effect on the wooden structure buildings. Therefore, there is still room for improvement.
