Earthen archaeological site protection material and preparation method thereof
The invention provides an earthen archaeological site protection material and a preparation method thereof. The material comprises a plant source urease solution, a urea solution, a calcium chloride solution and cane sugar; the plant source urease solution, the urea solution, the calcium chloride solution and the cane sugar are mixed according to the mass ratio of 10: 5: 5: 1. Sucrose modifying enzyme is added into the components to induce calcium carbonate precipitation, so that on one hand, a nucleation site is provided for the generated calcium carbonate and is used as an organic template for regulating and controlling the growth of the calcium carbonate, and the structure of the calcium carbonate is more compact; on the other hand, the sucrose has a certainviscidity, the sucrose contains hydroxyl functional groups which are coordinated with calcium ions in the solution, so that the curing protection effect is remarkably improved, the compatibility of the material with a soil body is good, and the surface hardness, the salt corrosion resistance, the weather resistance and the water repellency of the soil body are remarkably improved; and the preparation process is simple, green and environment-friendly, carbon dioxide in air can be absorbed to accelerate solidification of the soil body, and the greenhouse effect is relieved.
一种土遗址保护材料及其制备方法，包括植物源脲酶溶液、尿素溶液、氯化钙溶液和蔗糖，所述植物源脲酶溶液、尿素溶液、氯化钙溶液和蔗糖按照10：5：5：1的质量比进行混合。通过在组分中加入蔗糖改性酶诱导碳酸钙沉淀，一方面为其产生的碳酸钙提供了成核位点，作为调控碳酸钙生长的有机模板，使得碳酸钙的结构更加致密，另一方面，蔗糖具有一定的粘性，且蔗糖中含有羟基官能团与溶液中的钙离子发生配位作用，使其固化防护效果显著提升，与土体兼容性好，显著提高了土体表面硬度、耐盐腐蚀性、耐候性和斥水性；本发明制备工艺精简、绿色环保，能吸收空气中的二氧化碳加速固化土体，缓解了温室效应。
