preparation example Construction

[0025] In some embodiments, the preparation method of the first protective agent composition comprises: at room temperature, according to the composition of the precursor of the first protective agent composition, vinyl POSS and hexadecyl trimethoxy Mix the silane evenly, then add ethanol and silica airgel in sequence, then add cooked tung oil dropwise, and finally add water, and keep stirring until a uniform light brown transparent liquid is obtained.

[0026] Further, the protection method specifically includes: coating the first protective agent composition on the surface of stele-like cultural relics and air-drying, then reapplying the first protective agent composition and air-drying again, repeating four to five times, The transparent base protection layer is formed.

[0027] Among them, by using vinyl POSS, hexadecyltrimethoxysilane, etc., it can undergo polycondensation, crosslinking and other reactions under the action of water, ethanol, etc., and combine with silica ...

Embodiment 1

[0044] Embodiment 1: The protection method of a kind of stele class cultural relics provided in this embodiment comprises:

[0045] (1) Select basalt, limestone, and marble respectively, cut them into standard blocks of 5cm×5cm×5cm as samples, polish the surface with sandpaper, and carve about 0.5cm×0.5cm on one side of the surface The inscribed Chinese characters, and then clean to remove the floating dust on the surface.

[0046] (2) The precursor of the first protective agent composition is provided, which includes 45wt% cooked tung oil, 0.3wt% silica airgel, 3.2wt% vinyl POSS, 4wt% hexadecyltrimethoxysilane, 3.5 The wt% is ultrapure water, and the rest is ethanol, wherein the particle size of the silicon dioxide airgel is 1-5 μm. At room temperature, according to the composition of the precursor of the first protective agent composition, uniformly mix vinyl POSS and hexadecyltrimethoxysilane, then add ethanol and silica airgel in sequence, and then dropwise add cooked Tu...

Embodiment 2

[0049] Embodiment 2: The protection method of a kind of stele class cultural relics provided in this embodiment comprises:

[0050] (1) Same as Example 1.

[0051] (2) Basically the same as in Example 1. But the precursor of the first protective agent composition includes 40wt% cooked tung oil, 0.5wt% silica airgel, 3wt% vinyl POSS, 5wt% hexadecyltrimethoxysilane, 5wt% ultrapure water, and the rest to ethanol. Among them, the particle size of silica airgel is 1-5 μm (purchased from Suzhou Tongxuan New Material Co., Ltd.).

[0052] (3) is basically the same as in Example 1. But the precursor of the second protective agent composition contains 90wt% ether, 7.5wt% vinyl-terminated polymethicone oil, 1wt% tris(dimethylsiloxy)phenylsilane, 20-40ppm chloroplatinic acid, 1wt% % 2-methyl-3-butyn-2-ol and about 0.5 wt% nano manganese oxide particles, the particle diameter of the nano manganese oxide particles is 10-20nm.

[0053] (4) substantially the same as Example 1, but the th...

Abstract

The invention discloses a protection method for stone artifacts, which comprises: the surface of the stone artifacts is cleaned; a first protective agent composition is coated on the surface of the stone artifacts and solidified at room temperature to form a transparent basic protective layer; a second protective agent composition is coated on the basic protective layer and solidified to form a transparent intermediate protective layer under room temperature and illumination; and a third protective agent composition is coated on the intermediate protective layer and solidified at room temperature to form a transparent surface protective layer. By using the protection method for the stone artifacts, steles can be well protected, and the original morphology and structure can be maintained. At the same time, the formed composite protective layer has good waterproof, water-resistant, oil-dredging, corrosion-resistant, wear-resistant, corrosive gas and ultraviolet ray barrier property and other comprehensive properties. Besides, cultural relics can also maintain the natural 'breathing' effect.

Description

technical field [0001] The invention relates to a method for protecting stone cultural relics, in particular to a method for protecting stone monument cultural relics. Background technique [0002] Generally speaking, stone cultural relics will change their physical state and chemical composition under the long-term action of temperature, atmosphere, water and microorganisms, and thus be weathered. [0003] In order to protect such cultural relics, the industry has proposed various schemes. One of the common methods is to apply protective agent on stone cultural relics. At present, the most commonly used cultural relic protection agents are inorganic and organic. Among them, the inorganic protective agents include lime water, strontium hydroxide, barium hydroxide, alkaline silicate, etc. Organic protective agents include paraffin wax, epoxy resin, acrylic resin, silicone resin and the like. The above-mentioned inorganic protective agent mainly uses the salt in the soluti...
