example 1
[0048] Example 1 white marble repair material
[0049] Magnesium cement: 40-50 parts
[0050] White marble powder (sand): 40-50 parts
[0051] White mica flakes: 0-10 parts
[0052] Silica sol: 10-15 parts
[0053] Dispersant: 1-3 parts
[0054] Polypropylene fiber: 1-2 parts
[0055] Cellulose fibers: 1-3 parts
[0056] Water: 15-20 parts
[0057] The construction method is as follows: clean up the dust, mud, oil and other pollutants in the damaged stone area that may affect the bonding strength of the interface between the repair material and the area to be repaired; and clean the narrow cracks or shallow surface pits Widen or deepen the hole, and moisten the area to be repaired with clean water; because this product condenses and hardens quickly, the material is suitable for on-site preparation, mixing and use, and the remaining product mixture is used each time. It needs to be cleaned and cleaned in time to avoid rapid solidification in the mixing container.
example 2

Abstract
The invention relates to building stone repairing. A rapid repair material based on building broken stones comprises a gelation mixture which quickly solidifies with water, wherein the gelation mixture comprises the following components in parts by weight: 40-55 parts of magnesium phosphate cement, 40-50 parts of sand and 10-15 parts of silica sol. A preparation method of the materials comprises the following steps of: 1, preparing the magnesium phosphate cement; 2, mixing the magnesium phosphate cement, the sand and the silica sol so as to form the gelation mixture which comprises the following components in parts by weight: 40-55 parts of magnesium phosphate cement, 40-50 parts of sand and 10-15 parts of silica sol. The gelation mixture can be quickly solidified with the water to repair the stones. In addition, the gelation mixture is gelatineous before being solidified and facilitates construction; after the solidification, the small solidification shrinkage rate and a durable effect are obtained; and the repair material has high hardness and good water resistance after the solidification.
Description
technical field [0001] The invention relates to the restoration of stone materials in buildings, in particular to a material for repairing stone materials. Background technique [0002] There are a large number of stone buildings preserved in ancient buildings in China, such as exquisitely carved stone platform bases, railings, tall and erect stone pillars, huge stone tablets, and white marble bridges. With the advancement of society, the development of science and technology, and the improvement of living standards, people in modern life have also begun to widely use elegant and beautiful natural stone as decorative materials to beautify the living environment and working environment, such as decorating residences, hotels, office buildings, stations, etc. , terminals, shopping malls, theaters, etc. [0003] Some stones have sand holes and pits on the surface, some stones have natural cracks or fissures, and some stones will be damaged, broken edges or missing corners durin...
