Embodiment 1

[0028] Add 50g of distilled water into the beaker, heat to 55°C, keep constant temperature, weigh 1g of Carbomer 940, slowly add it in a small amount from the vortex of the stirrer, after adding Carbomer, observe a small amount of Carbomer knot block, and continued to stir for 30 minutes until the carbomer aqueous solution became transparent. Add 0.01g of diatomaceous earth to the carbomer aqueous solution to reduce the air bubbles in the carbomer gel, then add 0.15g of N,N'-bis(2-hydroxyethyl)oxamide under stirring to adjust the gel When it is observed that the carbomer forms a transparent viscous colloid, add 0.05g of ammonia water and 0.01g of Tween-80, stir evenly, add distilled water to 100g, and cool to room temperature to obtain the lampblack gel cleaning agent.

[0029] Depend on figure 1 It can be seen that the gel cleaning agent has a typical three-dimensional network pore structure and the pores are relatively uniform. Measured by the NDJ-8S rotational viscometer,...

Embodiment 2

[0031] Add 50g of distilled water into the beaker, heat to 55°C, keep constant temperature, weigh 0.5g of carbomer, slowly add it in a small amount from the vortex of the stirrer, after adding carbomer, observe a small amount of carbomer knot block, and continued to stir for 30 minutes until the carbomer aqueous solution became transparent. Add 0.01g of diatomaceous earth to the carbomer aqueous solution to reduce the air bubbles in the carbomer gel, then add 0.10g of N,N'-bis(2-hydroxyethyl)oxamide under stirring to adjust the gel When it is observed that the carbomer forms a transparent viscous colloid, add 0.1g of ammonia water and 0.01g of Tween-80, stir evenly, add distilled water to 100g, and cool to room temperature to obtain the lampblack gel cleaning agent ( See figure 2 ), measured by the NDJ-8S rotational viscometer, its viscosity at No. 4 rotor 0.3RPM rotating speed is 580000mPa·s.

Embodiment 3

[0033]Add 50g of distilled water into the beaker, heat to 55°C, keep constant temperature, weigh 1.5g of carbomer, slowly add it in a small amount from the vortex of the stirrer, after adding carbomer, observe that there will be a small amount of carbomer knot block, and continued to stir for 30 minutes until the carbomer aqueous solution became transparent. Add 0.01g diatomaceous earth to the carbomer aqueous solution to reduce the air bubbles in the carbomer gel, then add 0.20g N,N'-bis(2-hydroxyethyl)oxamide under stirring to adjust the gel When it is observed that the carbomer forms a transparent viscous colloid, add 0.15g of ammonia water and 0.01g of Tween-80, stir evenly, add distilled water to 100g, and cool to room temperature to obtain the lampblack gel cleaning agent ( See image 3 ), measured by the NDJ-8S rotational viscometer, its viscosity at No. 4 rotor 0.3RPM rotating speed is 666000mPa·s.

Abstract

The invention discloses a gel cleaning agent for lampblack on the surface of a polychrome cultural relic. The gel cleaning agent for lampblack on the surface of the polychrome cultural relic comprises, by mass, 0.5%-1.5% of Carbomer 940, 0.05%-0.15% of ammonium hydroxide, 0.05%-0.25% of N,N'-bi-(2-ethoxy)-oxamide, 0.005%-0.015% of kieselguhr, 0.005%-0.015% of non-ionic surface active agent and the balance distilled water. The transparent alkaline gel cleaning agent is prepared based on the slow-release property and the adsorbability of gel, the method for preparing the gel cleaning agent is simple, the gel cleaning agent does not flow in use and is easy to control, contact type cleaning can be achieved, environment-friendly cleaning of the surface of the cultural relic is achieved by controlling and releasing cleaning components to dissolve and absorb lampblack on the surface of the cultural relic, and the gel cleaning agent is suitable for removing lampblack on the surfaces of various objects such as colored paintings, metal and stone and has a certain application prospect in the aspect of cleaning objects polluted by household and industrial lampblack.

Description

technical field [0001] The invention belongs to the technical field of cultural relics protection, and in particular relates to a cleaning agent for cleaning soot and dirt on the surface of cultural relics, in particular to a gel cleaning agent capable of cleaning soot and dirt on the surface of painted cultural relics. Background technique [0002] Oil fume pollution is one of the most common diseases on painted cultural relics (murals and painted stone carvings) in my country. It is generally formed when the oily fume produced by believers burning scented wax gathers on the surface of cultural relics. Oil fume pollutants on the surface of cultural relics mainly contain a large amount of carbon black, thermal cracking products of wood and plant cellulose, and aromatic compounds, which become thick and solid over time and are difficult to remove. At present, the cleaning techniques for oil fume pollution of cultural relics mainly include the following methods: (1) using Na ...
