Abstract

The invention discloses composite polymer-pattern cultural protection paint and preparing method, which comprises he following parts: host, cross linker and diluent, wherein the host contains 74 percent tetrafluoride resin, 0.4 percent defoamer, 0.2 percent specific levelling agent solution, 0.6 percent specific ultraviolet absorbent, 0.3 percent specific composite rare-earth oxide,6 percent functional delustring filler, 4.5 percent butyl acetate, 7 percent mixing high-boiling point solvent, 3 percent xylene and 4 percent 100# solvent; the cross linker contains 80 percent HDI polymer, 0.2 percent absorbent, 0.3 percent inert filling gas and 19.5 percent solvent; the rate of host, cross linker and diluent is 7:1:5-7, which are cured for 20 min to match for using.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a cultural relic protection paint and a preparation method thereof. The cultural relic protection paint of the present invention can be coated on the surface of cultural relics such as bronzes, textiles, paper, stone, brick, porcelain, ironware, painted pottery, etc., to protect cultural relics. 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 pollution and light radiation. Especially the industria...

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 fluororubber protective film is still not enough, 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.
