Embodiment 1

[0063] This embodiment is a kind of anti-weathering reinforcing agent for loess relics and its preparation and reinforcement method. The test site is the non-relic area of ​​Hanguangmen Relics Museum of Tanghuang City Wall in Xi'an City, Shaanxi Province.

[0064] The anti-weather reinforcement material for the loess ruins used in this example contains two types of reinforcements, CB-I and CB-II, among which the reinforcement agent CB-I is an anhydrous solution that dissolves 5 grams of oxalic acid and 1 milliliter of phosphoric acid in every 1000 milliliters of ethanol. Color clear solution; No. CB-Ⅱ reinforcement is a colorless and clear solution that dissolves 15 grams of barium hydroxide in every 2500 milliliters of methanol. The chemical raw materials are all industrial pure.

[0065] When preparing the above-mentioned anti-weather reinforcement agent for loess relics, the following steps are included:

[0066] Step 1: Preparation of No. CB-I reinforcing agent: Dissolve ...

Embodiment 2

[0073] This embodiment is a kind of anti-weathering reinforcing agent for loess ruins and its preparation and strengthening method. The test site is the non-heritage area of ​​Xiadian Village, Chang'an County, Shaanxi Province. The moisture content of the test area is 5.12%.

[0074] The anti-weather reinforcement material for the loess ruins used in this example contains two types of reinforcement, CB-I and CB-II. Among them, the reinforcement agent CB-I is 10 grams of oxalic acid and 5 milliliters of phosphoric acid dissolved in every 1000 milliliters of ethanol. It is prepared as a colorless and clear solution; CB-II No. reinforcement is prepared by dissolving 50 grams of barium hydroxide in 2500 ml of methanol to prepare a colorless and clear solution. The chemical raw materials are all industrial pure.

[0075] When preparing the above-mentioned anti-weather reinforcement agent for loess relics, the following steps are included:

[0076] Step 1: Preparation of No. CB-I ...

Embodiment 3

[0083] This embodiment is a kind of anti-weathering reinforcing agent for loess ruins and its preparation and strengthening method. The test site is the non-relic area of ​​Xiadian Village, Chang'an County, Shaanxi Province, and the moisture content of the test area is 9.83%.

Abstract

The invention relates to a loess relic efflorescence-proof reinforcing agent and a preparation and reinforcing method thereof. The method comprises the following steps: dissolving 5-25g of oxalate and 1-15ml of CB-I reinforcing agent prepared from phosphoric acid in every 1000ml of ethanol, and dissolving 15-150g of CB-II reingorcing agent prepared from barium hydroxide in every 2500ml of carbinol; and utilizing a dual reinforcing method of carrying out microprecipitation and adsorption on the losess relic by the CB-I reingorcing agent and the CB-II reingorcing agent, and utilizing a three-step dripping mode to achieve the reinforcing effect. By adopting the technical scheme of the invention, a loess relic efflorescence-proof reinforcing material and the reinforcing method which are suitable for dry, semi-dry and humid environment conditions of a semihumid area are obtained. The chemical raw materials of the invention are technical pure, and has the advantages of low cost, simple manufacturing process and reinforcing method, and easy operation, thereby having good market development prospect. After being processed by the loess relic efflorescence-proof reinforcing material of the invention according to the reinforcing method, the loess relic shows excellent reinforced effect.

Description

technical field [0001] The invention relates to the technical field of cultural relics protection materials, in particular to a reinforcement material for protecting loess relics. Background technique [0002] Earthen ruins are traces of production and life in a specific period left by ancestors, carrying important historical and cultural information, and are of great value to ancient culture research; however, the particularity of soil pan-alkali, weathering, water erosion and biological reproduction caused Huge difficulties in the protection of earthen sites. At present, the diseases of earthen sites are mainly affected by their own composition, structure and environmental factors, which make it difficult for the soil to maintain water balance, and eventually lead to a decrease in bearing capacity after excessive water absorption or desertification of soil due to excessive water loss. Therefore, the development of anti-weathering reinforcement protection materials and rei...
