Description
Technical Field
The invention relates to the field of ancient building restoration, in particular to an ancient building wood member restoration agent and a restoration method thereof.
Background
The ancient Chinese building takes wood and tiles as main building materials and takes a wood structure as a main structural mode. The wood structure is formed by mainly inserting and overlapping components such as wood upright posts, beam purlins, purlin rafters and the like, flexible and variable spaces are easy to create, the wood structure has the advantages of good anti-seismic performance, convenient material taking, high construction speed and the like, but the wood belongs to combustible materials and is easy to decay by termites and wood decay bacteria, so the repairing and protection of the wood structure are key and difficult points in the ancient building repairing engineering. Meanwhile, the wood members of the ancient buildings are easy to crack after years of ceremony, so that the attractiveness of the ancient buildings is greatly influenced, and the strength of the wood members is influenced.

the invention also provides a method for repairing the ancient building wood member repairing agent, which comprises the following steps:
s1, removing dust and impurities on the surface of the wood member and in the cracks;
s2, judging the surface color of the wood member, selecting proper pigment and formula, and weighing the components according to the formula;
s3, placing the weighed epoxy resin, silicon-containing polycarbonate resin, high-aluminum bronze powder, perfluoroalkyl acrylic additive, trisnonylphenyl phosphite, acrylonitrile-styrene copolymer grafted glycidyl methacrylate, glass fiber and pigment in a high-speed shearing machine for shearing and mixing to obtain a repairing agent;
s4, filling the obtained repairing agent into a spray gun, injecting the repairing agent into cracks of the wood component by using the spray gun, and leveling by using a scraper;
and S5, after the repairing agent is solidified, polishing the solidified redundant repairing agent by using a polishing machine, and drawing/carving a corresponding pattern on the repairing agent.
Further, in the step S3, the shear mixing is carried out for 5-10 min under the conditions that the shear rate is 50-150S and the shear force is 50-150 Pa.
The invention has the following beneficial effects:
the method can realize the reinforcement and repair of the defects of the ancient building wood members, can effectively carry out internal deinsectization and corrosion prevention treatment on the wood members damaged by worms, and has good overall aesthetic degree and good weather resistance of repaired parts.
