Problems solved by technology

But the effect is not ideal, there are various problems
For example, alum, which was used for wood protection earlier, has weak permeability, and sulfuric acid is released inside the wood treated with it, which shows that the wood cultural relics treated with alum are more acidic, so that the residual lignin inside may be Degraded; polyethylene glycol applied later, although polyethylene glycol is reversible, but this material will be randomly degraded and cracked within the treated object over time, and the stability is poor, such as Sweden treated with polyethylene glycol The vasa warship has a darker color, almost pitch-black, unclear texture, and loses the natural color of the wood; the melamine-formaldehyde (Kauramin) method developed in Germany, although melamine-formaldehyde is stable, easily soluble in water, strong and durable Good durability, maintaining the original color of the object, etc., but the reinforced wood is brittle and fragile, and the process is irreversible

Embodiment 1

[0058]

[0059] Stone protection fluid Natural stone is a relatively stable structure formed by molecules after tens of millions of years of natural influence. There are countless small micropores inside the stone, and the number of pores varies in size. Pollutants on the stone surface penetrate into the interior of the stone through tiny micropores, forming water spots, white blooms, rust, stains and weathering.

[0060] Stone protection liquid is a kind of penetrating protection liquid. It is different from paint type and paint type protection liquid. It will not form an isolation film on the surface, so it will not change the luster, color, original appearance and quality of the cultural relic itself, nor will it fall off, will corrode. It is water-based and has zero VOC emissions (no organic compounds). Its mechanism is to infiltrate from the base village, fill the capillary pores inside the substrate, and form a reticular crystal layer, thereby playing a protective ro...

[0062]

[0063] Calligraphy and painting protection liquid (ZW-PS02) Calligraphy and painting protection liquid is sprayed on ancient calligraphy and painting, no matter the substrate is paper, silk, silk, satin and stone, etc., it can prevent the ink marks, colors and prints of calligraphy and painting from being blurred and blurred. Color, color mixing and other phenomena, and make the calligraphy and painting after spraying the protection liquid produce the miraculous effect of increasing water, increasing oil and anti-pollution. Prevent microbial growth, prevent mildew, and can also meet the protection requirements of cultural relics for preventing aging, repairing the old and maintaining the original appearance, texture and flexibility.

Embodiment 3

[0065]

[0066] Wood protection liquid (ZW-PS03) wood protection liquid is an environmentally friendly water-based protection liquid. Oil anti-pollution protection can also prevent mildew and cracking caused by hot and cold weather, dry and wet changes. After 30 minutes of drying, the product is colorless and transparent, and does not affect the color and texture of the original wood substrate.

Abstract

The invention provides a nanometer aqueous green environment-friendly protective solution, which belongs to the field of preservation of cultural relics. The protective solution provided by the invention has excellent performances like weatherability, water resistance, oil resistance, heat resistance, resistance to chemicals and solvents, dirt resistance, insulating properties, cleanness, low refractiveness (transparency), gas permeability (respirability), lubricity, no viscosity, resistance to acid and base, etc. and can be extensively applied to a variety of fields of preservation of cultural relics.

Description

【Technical field】 [0001] The invention belongs to the technical field of cultural relics protection, and in particular relates to a nanoscale water-based protective liquid and its preparation and application, and is especially suitable for the protection and reinforcement of cultural relics. 【Background technique】 [0002] my country is one of the ancient civilizations in the world with rich historical and cultural heritage. As the "repository" of ancient cultural information, cultural relics have extremely high historical, artistic, scientific and technological value. Because its own material is affected by environmental factors, it often happens that it ages and deteriorates until it disappears. Once the cultural relics disappear, all the historical and cultural information pages they carry will disappear, so the cultural relics and cultural heritage need to be protected. [0003] The unearthed artifacts are more sensitive to changes in the temperature and humidity of th...
