Problems solved by technology

However, in the process of rubbing, due to the alternation of dry and wet and repeated friction, the surface of the stele will inevitably be weathered and polluted by abrasion, which will cause damage to the stele and cause irreparable losses.

Embodiment 1

[0026] A stele rubbing protection agent, comprising raw materials in the following mass ratio: cyclododecane 10.5: petroleum ether 24.6: n-heptane 23.8: Daikin GM-105D 15.9: PEGASOL 3040 25.2.

[0027] The preparation method of stele rubbing protective agent comprises the following steps:

[0028] (1) Weigh cyclododecane, petroleum ether and n-heptane respectively, add them to a flask, heat and stir in a water bath at 70°C, and dissolve to form a homogeneous solution system;

[0029] (2) Weigh PEGASOL 3040 into another flask, heat and stir in a water bath at 65°C, add Daikin GM-105D under stirring conditions, and stir until completely dissolved to form a mixed solution system;

[0030] (3) Add the homogeneous solution system of step (1) into the mixed solution system of step (2), continue to stir and mix evenly, and naturally cool down and solidify under the condition of constant stirring, to obtain the product.

Embodiment 2

[0032] A stele rubbing protection agent, comprising raw materials in the following mass ratio: cyclododecane 9.5: petroleum ether 20.3: cyclohexane 25.8: Daikin GM-105D 17.3: EXXSOL D40 27.1.

[0033] The preparation method of the stele rubbing protection agent refers to Example 1, the difference is that the temperature of the water bath in step (1) is 65°C, and the temperature of the water bath in step (2) is 60°C.

Embodiment 3

[0035] A stele rubbing protection agent, comprising raw materials in the following mass ratio: cyclododecane 11.2: n-heptane 31.2: Daikin GM-105D 19.8: butyl acetate 37.8.

[0036] The preparation method of the stele rubbing protection agent refers to Example 1, the difference is that the temperature of the water bath in step (1) is 65°C, and the temperature of the water bath in step (2) is 75°C.

Abstract

The invention discloses a novel stone tablet rubbing protective agent and a preparation method thereof. The protective agent is mainly prepared from, by mass, 5.6-11.5 parts of cyclododecane and 10.5-21 parts of fluorine polymer. Accordingly, cyclododecane is adopted as one of the main raw materials, and cyclododecane has complete hydrophobicity and can be applied to cultural relics sensitive to water or an aqueous solution to serve as a waterproof barrier coating. Daikin GM-105D is selected as the applied fluorine polymer, and the fluorine polymer has the excellent heat resistance, chemical resistance, weather resistance, stain resistance, electrical characteristics and the like and has the unique properties such as non-sticky performance and self-lubricating. Accordingly, cyclododecane and the fluorine polymer are compounded to form a composite material, and the strength, permeability, alkali resistance, stain resistance, heat resistance and weather resistance of the product are improved. The evaporation speed of cyclododecane can be effectively slowed down, evaporability of the product is lowered, and the product can be removed freely.

Description

technical field [0001] The invention relates to a stele rubbing protection agent and a preparation method thereof, belonging to the field of cultural relics protection. Background technique [0002] Stone stele rubbings refer to pieces of paper that rub the shape of inscriptions and stone inscriptions and the characters and patterns on them. It is an ancient traditional skill in my country. The basic method of rubbing is: first clean the surface of the stele, brush the patterns or characters to be rubbed as clearly as possible, cover it with rice paper of appropriate size, moisten the paper lightly, and then cover the wet paper with a layer The soft absorbent paper protects the surface of the paper, and gently taps it with a brush to make the wet paper stick to the surface of the object, which rises and falls with the patterns and characters on it. Then remove the covered layer of paper, wait for the wet paper to dry slightly, dip a proper amount of ink with the poker, spre...
