Problems solved by technology

The use of WD-10 reduces the gas permeability of the stone, hinders the normal migration of water vapor, and may accelerate the deterioration of stone cultural relics
At the same time, it was found that the waterproof performance of WD-10 will be significantly reduced after ultraviolet light irradiation, and the damage performance against soluble salts will also be reduced, which will affect the effect of cultural relics protection.

Embodiment 1

[0037] (1) Preparation of waterproof material

[0038] Weigh 1.35g of nano-TiO with an average particle size of 25nm 2 , adding 64.6 g of absolute ethanol, 25 g of water, 0.0405 g of aminopropyltriethoxysilane and 0.0135 g of polyethylene glycol octylphenyl ether to prepare solution A. Take 10mL of WD-10 and add 90mL of absolute ethanol to prepare solution B.

[0039] After solution A was dispersed ultrasonically for 20 minutes at 40°C, it was dispersed at 6000 r / min at 70°C for 60 minutes at high speed. Take 1 mL of the above-mentioned solution A after ultrasonic and high-speed dispersion, add 100 mL of solution B, and ultrasonicate for 30 min at room temperature to obtain the TiO 2 - Silicone composite waterproof material for stone cultural relics. Brush the waterproof material evenly on the surface of the stone sample, and then apply it next time after natural drying. Waterproof treatment is performed 3 times, and the treated sample is placed at room temperature for 1 we...

Embodiment 2

[0060] Similar to the preparation method of Example 1, the waterproof material described in Table 1 can be prepared, wherein the average particle size of nano titanium dioxide is 60nm.

[0061]

Embodiment 3

[0063] Similar to Example 1, change the amount of TiO in the solution by changing the addition of solution A and solution B 2 concentration, the experimental results are shown in Table 2.

[0064]

[0065] It can be seen from Table 2 that the wetting angle of the stone treated with WD-10 and the waterproof material of the present invention is significantly increased, and the waterproof performance is significantly improved.

[0066] The gas permeability of the stone after the waterproof material treatment is all reduced, especially the worst gas permeability of the stone protected by WD-10, and the gas permeability of the stone protected by the waterproof material of the present invention is better than that of WD-10, and the TiO 2 The higher the concentration, the better the effect. TiO 2 If the concentration is too high, the solution will be opaque, and the appearance of the stone will be changed after treatment, which violates the basic principle of cultural relics pro...

Abstract

The invention discloses a waterproof material for stone cultural relics, which is prepared from the following components. Each component and its weight part is titanium dioxide 200~3000, WD-10 5×105~3×106, polyethylene glycol octyl phenyl ether 1 to 30, aminopropyltriethoxysilane 5 to 90, solvent 7×106 to 9×106, the solvent is a mixed solvent of ethanol and water, and its weight ratio is: 100:1 to 500 :1. The waterproof material of the present invention has a longer life and higher stability than the commonly used cultural relic waterproofing agent WD-10, especially the salt resistance is significantly increased; the preparation process of the present invention is simple and easy to operate. The raw materials are alcohol and water liquid solutions, and the properties are stable and green. Environmental friendly.

Description

technical field [0001] The invention relates to a waterproof material for stone cultural relics and a preparation method thereof, belonging to the technical field of stone cultural relics and stone material protection. Background technique [0002] Many stone cultural relics and stone buildings in our country have been eroded by rain, snow, moisture and groundwater for a long time, and they have been seriously weathered. Many of them are in an endangered state. The common protection method is to use waterproofing agent for treatment. At present, the most commonly used waterproof material for cultural relics protection is WD-10 (the main component is dodecyltrimethoxysilane). Since the 1990s, WD-10 has been used in the waterproof protection of many stone cultural relics such as the stone carvings of Qianling in Shaanxi, the General Tomb of Goguryeo and the rock of Zhetianjing Tomb. However, with the continuous deepening of the research on stone cultural relics protection mat...
