Earthen ancient cultural relic reinforcing agent and preparation method thereof

Abstract

The invention discloses an earthen ancient cultural relic reinforcing agent and a preparation method thereof. The earthen ancient cultural relic reinforcing agent comprises the following components in parts by mass: 11-13 parts of a styrene-acrylic emulsion and / or 12-16 parts of an organosilicone-acrylic emulsion, 3-5 parts of a cationic surfactant, and 60-80 parts of a dispersing agent. The preparation method of the earthen ancient cultural relic reinforcing agent comprises the following steps: step one, diluting the emulsion by using deionized water until the content of solid in the emulsion is 8% by mass; step two, dissolving the cationic surfactant in a cyclohexane solvent according to a mass ratio of 1 to 5; and step three, slowly adding the cyclohexane solution with the cationic surfactant into the diluted emission under stirring at a high rate until a split phase is generated in the emulsion, stopping stirring and standing; removing lower-layer water and the upper-layer cyclohexane solvent after layering a mixture to obtain resin particle condensate; and dispersing the condensate in a ketones solvent again under stirring at a high rate to prepare uniform ketones solvent dispersoid.

Description

technical field [0001] The invention relates to cultural relics protection materials, in particular to a reinforcement agent for soil relics and cultural relics and a preparation method thereof. Background technique [0002] In the protection of cultural relics, the weather protection of soil relics is an important issue. Some relics such as city walls, houses, cellars, kilns, granaries and other relics mainly composed of soil will be destroyed soon after excavation due to various natural factors. The phenomenon of weathering is mainly manifested as surface loosening and falling off. In order to control this phenomenon and protect the soil relics, cultural relics protection circles often use chemical materials to spray the surface of the soil relics in order to improve their weathering resistance. When carrying out the anti-weathering reinforcement protection test on soil relics, it is found that the strength of the emulsion and loess is improved after being consolidated, a...

AI Technical Summary

Problems solved by technology

When carrying out the anti-weathering reinforcement protection test on soil relics, it is found that the strength of the emulsion and loess is improved after being consolidated, and the consolidated body has good water resistance. Although this is beneficial to the protection of soil relics, when using emulsion to spray or impregnate When removing soil relics, due to the existence of water, the surface of the soil relics will deform, fall off or even collapse, which is not allowed in the protection of cultural relics
