Problems solved by technology

However, with the continuous deepening of cultural relics protection work, the shortcomings of B72's poor light aging resistance have gradually emerged.
Under light radiation, the B72 molecular chain degrades, causing fission such as yellowing, brittleness, and low strength, which affects the protection effect of painted cultural relics

Embodiment 1

[0036] (1) Preparation of anti-light aging reinforcement materials

[0037] Weigh 1.25g nano-SiO 2 Add 100mL of absolute ethanol / deionized water mixed solvent with a volume ratio of 85 / 15, add 0.0125g KH550 and 0.0375g OP-10 to prepare solution A. Weigh 2g of B72 and dissolve it in 8g of ethyl acetate to prepare solution B.

[0038] Solution A was ultrasonically dispersed at 60 °C for 120 min. Take 12.8mL of the above-mentioned solution A after ultrasonic dispersion and add it to 10g of solution B to obtain the SiO 2 -B72 composite anti-photoaging reinforcement material for painted cultural relics. Apply the above reinforcement material evenly on the glass slide to form a film, paint on the surface of the painted sample block and then repeat the brushing once, and place the treated sample at room temperature for 1 week before use;

[0039] (2) Anti-light aging performance test

[0040] Place the prepared film material and painted sample block at a distance of 2cm from the...

Embodiment 2

[0066] Similar to the preparation method of Example 1, the waterproof material described in Table 3 can be prepared.

[0067]

Embodiment 3

[0069] Similar to Example 1, change the amount of SiO in the solution by changing the amount of solution A and solution B added 2 concentration, the experimental results are shown in Table 4.

[0070]

[0071] As can be seen from Table 4, the material of the present invention is significantly improved compared with the photoaging performance of B72, and the degree of improvement of the photoaging performance of the material of the present invention is comparable to that of SiO 2 Concentration related, and SiO 2 The higher the concentration, the better the effect.

Abstract

The invention discloses an anti-light-ageing reinforcement material of colored relics. The reinforcement material is prepared from the following components in parts by weight: 500-1,200 parts of silicon dioxide, 6,000-20,000 parts of B72, 5-40 parts of polyethylene glycol octylphenol ether, 4-20 parts of aminopropyl triethoxy silane, 5,000-80,000 parts of a 85%-95% ethanol aqueous solution and 30,000-200,000 parts of ethyl acetate. Compared with a common reinforcement material B72 of the colored relics, the anti-light-ageing reinforcement material is relatively long in service life and relatively high in stability, especially, the light ageing resistance is remarkably improved, and a preparation process of the anti-light-ageing reinforcement material is simple and convenient to perform.

Description

technical field [0001] The invention relates to a color-painted cultural relic anti-light aging reinforcement material and a preparation method thereof, belonging to the technical field of cultural relic protection. Background technique [0002] Painted cultural relics refer to cultural relics made by applying pigments mixed with glue on pottery, stone and other substrates. In our country, it has a wide range of distribution and a large number of existences. The famous Qinshihuang Terracotta Warriors and Horses painted pottery and Dunhuang murals are typical representatives of painted cultural relics. Painted cultural relics have extremely high historical value, artistic value and scientific value, but the rubber in the painted cultural relics will age under the radiation of light, causing the pigment to fall off. It became gray plain terracotta figurines. The commonly used protection method is to use reinforcement materials for protection treatment to improve color stabil...
