Problems solved by technology

The invention patent application with the application number of 200410041244.0 discloses a method of protecting cultural relics by dissolving fluororubber in an organic solvent and coating the solution on the surface of cultural relics. This method utilizes the anti-oxidation performance and certain elasticity of fluororubber to solve the problem Prior to this application, the prior art had the disadvantages of becoming brittle, hard, peeling, and producing luster on the surface of cultural relics. However, the wear resistance and hardness of fluorine rubber were not enough, and its chemical structure was not stable enough, so it was applied on the surface of cultural relics. The durability of the fluorine rubber protective film still needs to be improved, especially when it is necessary to protect the cultural relics that are exposed to the wild all the year round and withstand the sun and rain.

Abstract

The invention discloses a tetrafluoride resin appliance on the cultural protection, which is characterized by the following: adapting tetrafluoride resin as main connecting material and HDI polymer as main cross linker; adding functional adjuvant, delustring filler; taking mixing organic solvent as diluent; matching to form paint; coating on the surface of culture. the tetrafluoride resin poseeses good weatherability and superior resistance to oxidation, which displays durability.

Description

technical field [0001] The invention relates to a method for protecting cultural relics, in particular to a method for protecting cultural relics with tetrafluororesin as the main connecting material. The method of the invention can protect the surface of cultural relics such as bronze ware, textiles, paper, stone, brick, porcelain, ironware, painted pottery, etc., and is especially suitable for large-scale stone cultural relics exposed in the wild. Background technique [0002] Our country has a splendid history of 5,000 years, and there are a large number of historical sites and cultural relics that need to be protected. It is a complex and arduous systematic project to protect the unearthed ancient bronzes, pottery, textiles, wood lacquerware, paper, Dunhuang murals, stone carvings, Buddha, and stone tools exposed to the wild and murals exposed to the air. Environmental factors affecting cultural relics are mainly temperature, humidity, air pollut...
