Abstract:After the 1840, our country began to contact with the West, and some Western culture of science and technology began to have an impact on our country, such as the emergence of Western architecture in coastal and open areas. Some of the western-style decorations appear in these buildings, these different styles of floor tiles are little attention and not protected, such as the floor tiles of Qingdao Tianhou Temple. The investigation found that the floor tiles of Tianhou Temple, Qingdao, had been exposed to the natural environment for a long time and were still in use without any protective measures. Therefore, there were various kinds of diseases on the floor tiles, such as soil asphalt pollution, cracking, wear and tear, color off, broken and other diseases, a serious threat to the life and value of floor tiles. In order to protect floor tiles, cleaning and waterproof strengthening experiments were carried out, and based on the experience of domestic and foreign brick and stone materials protection, some suggestions were put forward, including dust removal, cleaning, surface reinforcement and waterproof treatment Physical isolation is used to prevent tourists from trampling on it directly.
