A kind of blue brick used for repairing ancient building walls and its preparation method

Abstract

The invention discloses a blue brick for repairing an ancient building wall. The blue brick comprises a brick blank and coating, wherein the brick blank comprises the following components: plastic clay, an inorganic dispersant, a pigment, a reinforcing fiber, an orange-peel agent, a water reducing agent and aggregate; the coating is petroleum asphalt coating. According to the blue brick for repairing the ancient building wall, after the surface of the brick blank is treated by a liquid petroleum asphalt diluent, on one hand, the attached liquid petroleum asphalt can enhance the anti-acid corrosion and anti-weathering effects, and after use, a time-induced special sense of vicissitudes can be formed on the surface of the brick; the blue brick for repairing the ancient building wall is low in cost, wide in raw material sources, and high in anti-corrosion, wear-resistant and anti-weathering effects; in addition, after restoration, cracks on the surface of an ancient building and the time-induced special sense of vicissitudes can be still maintained, so that a sense of repairing the ancient building as an old building is achieved; the blue brick is an environment-friendly and safe novel building material.

Description

technical field [0001] The invention relates to the technical field of restoration of ancient buildings, in particular to a green brick used for restoration of walls of ancient buildings and a preparation method thereof. Background technique [0002] The restoration of cultural relics such as modern historical buildings emphasizes "repairing the old as old", especially the restored parts should be consistent with the unrestored parts next to them, so as not to give people a feeling of "patching". The exterior walls and bricks of some ancient buildings have been severely damaged after years of wind and rain erosion and erosion.

Problems solved by technology

The exterior walls and bricks of some ancient buildings have been eroded and scoured by wind and rain for many years, resulting in serious damage

[0003] The restoration and protection of ancient buildings is due to the differences in the historical value of the protected buildings and the cultural and historical environment. Therefore, when restoring ancient buildings, the original style of the protected buildings should be restored as much as possible. Most of the blue bricks used for restoration can only imitate the size of the blue bricks, and cannot imitate the texture of the original ancient buildings, so that the appearance of the restored ancient buildings looks brand new, but it cannot reflect the vicissitudes and history of the years The thickness of the building destroys the historical value contained in the building
