Problems solved by technology

[0002] The principle in the restoration and protection of large trees in ancient buildings is not to destroy the main body of the large wood, as well as the reversibility and recognizability of the construction, to minimize the interference with the main body of the large wood, and to protect the original appearance and raw materials of the large wood as much as possible; Aging, wind and rain erosion, and building load-bearing can easily lead to cracks in the big wood. If it is not repaired in time, the big wood will lose its load-bearing function
Timely repair requires a repair material and process to better protect the large wooden components of ancient buildings, prolong the service life of the large wood, and avoid greater damage caused by cracks and irreparable losses

Abstract

The invention relates to the field of ancient building repairing, in particular to a wood crack repairing material for repairing a wooden structure of an ancient building. The wood crack repairing material is prepared from the following raw materials in parts by weight: 40-50 parts of ASA resin, 16-20 parts of octyl phenolic tackifying resin, 8-10 parts of shell powder, 3-5 parts of a perfluoroalkyl acrylic additive, 10-12 parts of trinonyl phenyl phosphite, 3-6 parts of an elastic silicone acrylic emulsion, 2-4 parts of bamboo fibers, 5-7 parts of an additive and 0-3 parts of pigment. The wood crack repairing material for repairing the wooden structure of the ancient building has excellent viscosity, weather resistance, corrosion resistance and strength, realizes repairing of wood cracks,well prevents re-expansion of the wood cracks, enables the repaired ancient building to be good in overall attractiveness, and reduces the influence on the original appearance of the ancient buildingas much as possible.
