Description
Technical Field
The invention belongs to the technical field of cultural relic protection, and particularly relates to a combination device of superfine fibers and silica gel for cultural relic protection and application thereof.
Background
The cultural relics are relics and traces left by human beings in the historical development process. Various cultural relics reflect the social activities, social relations and consciousness forms of human beings in various historical periods from different sides, and utilize the conditions of nature, nature improvement and the current ecological environment, and are precious historical cultural heritages of the human beings. The protection management and scientific research of the cultural relics have important significance for people to know the history and the creative power of the people, reveal the objective law of the human social development, know and promote the development of the modern and future society. The protection management and the scientific research are mutually connected, mutually promoted and supplemented, and the method is a systematic comprehensive science.
The process of cultural relic protection refers to a series of measures which are taken for historical remnants with historical value, cultural value and scientific value to prevent the historical remnants from being damaged, and the process is called cultural relic protection. Therefore, in a narrow sense, the meaning of the cultural relic protection is to protect various information existing on the cultural relic body as long as possible by prolonging the service life of the cultural relic body, and lays a foundation for people to know the activities of ancient human beings. In a broad sense, cultural relic protection or cultural heritage protection is meant for the welfare of modern and future people, i.e. all stakeholders associated with cultural heritage. The method not only plays a role in prolonging the life of cultural heritage for people and descendants, but also combines the information of extracting, researching and protecting the cultural relics with the information of showing and explaining the cultural heritage to the public to finally serve the whole society.
The Ultra-High Molecular Weight Polyethylene Fiber (UHMWPEF) is also called High-strength High-modulus Polyethylene Fiber, is the Fiber with the highest specific strength and specific modulus in the world at present, and is spun by Polyethylene with the Molecular Weight of 100-500 ten thousand. China is a big chemical fiber country but not a strong chemical fiber country, and according to expert introduction and statistics of related departments, the yield of the high-performance special fiber in China is only one percent of the world yield. Three major high performance fibers in the world today are: aramid fiber, carbon fiber and ultra-high molecular weight polyethylene fiber, and the aramid fiber is produced only in a small amount due to the technical problem in China at present; the carbon fiber is still in the stage of test and primary production, and the product can only be applied to the fields of wear-resistant filler and the like; since the key production technology of the ultra-high molecular weight polyethylene fiber is broken in the same year and in the same year of 1994, a plurality of industrial production bases for the ultra-high molecular weight polyethylene fiber are formed in China.
The invention discloses a preparation method of ultraviolet curing polyurethane coating for cultural relic protection, which is characterized in that glutinous rice slurry and film forming liquid are prepared, and then the glutinous rice slurry and the film forming liquid are put into a beaker for reaction through an ultraviolet absorbent and ammonium persulfate, so as to obtain sulfonated modified film forming liquid, and finally base liquid is obtained. Mixing the following components in parts by weight: adding butanediol 4 into the base solution to react to obtain a mixed solution, dropwise adding acetone into the mixed solution to obtain a modified mixed solution, stirring and mixing the modified mixed solution, the modified film-forming solution and ethylenediamine, carrying out heat preservation reaction, and cooling to room temperature to prepare the ultraviolet curing polyurethane coating for cultural relic protection; in addition, the Chinese patent publication No. CN211808263U in the prior art is invented and created to name a purified superfine fiber dust-free cloth, which comprises a dust-free cloth body, wherein a first anti-static layer is compounded on one side of the dust-free cloth body, a first oil absorption layer is compounded on one side of the first anti-static layer, a first wear-resistant layer is compounded on one side of the first oil absorption layer, a second anti-static layer is compounded on the other side of the dust-free cloth body, a second oil absorption layer is compounded on one side of the second anti-static layer, and a second wear-resistant layer is compounded on one side of the second oil absorption layer. However, the existing ultraviolet curing polyurethane coating for cultural relic protection has the problems of easiness in causing secondary damage to the cultural relic, easiness in shaking and damaging the cultural relic, no fixing and anti-moving function and complicated operation and application methods.
Therefore, it is necessary to invent a combination device of superfine fiber and silica gel for cultural relic protection and the application thereof.
