Preparation method of chitosan-reinforced carbonized hardened body
The invention discloses a preparation method of a chitosan-reinforced carbonized hardened body. The preparation method comprises the following steps: preparing a solution from low-molecular-weight chitosan and water according to a ratio of 0.02-0.1 g/mL for later use; selecting high-carbonization-activity calcium silicate minerals, and controlling the granularity of the minerals to be 5-15 micronsfor later use through grinding; and mixing ground calcium silicate with the aqueous chitosan solution, carrying out stirring and grinding to realize uniform mixing, carrying out compression molding,and performing curing in a carbon dioxide atmosphere to obtain a carbonized hardened body material. The chitosan is creatively utilized to reinforce the carbonized hardened body, so the carbonized hardened body has higher mechanical properties, and the chitosan can regulate the crystal form of a carbonized product in the carbonized body and promote dissolution of calcium ions, thereby promoting acarbonization Reaction. such a reinforcing technology is low in cost and simple in process, greatly improves the mechanical strength of the carbonized hardened body, and has good application prospects.
本发明公开了一种壳聚糖增强碳化硬化体的制备方法,包括以下步骤:将低分子量壳聚糖与水按0.02~0.1g/mL配置成溶液备用;选取高碳化活性硅酸钙矿物,通过粉磨控制其粒度为5‑15μm备用;将粉磨后的硅酸钙与壳聚糖水溶液混合,经搅拌、研磨后使其混合均匀,通过压制成型,然后在二氧化碳气氛下养护获得碳化硬化体材料。本发明创造性的利用壳聚糖增强碳化硬化体,使其具有更高的力学性能,壳聚糖在碳化体中可以调控碳化产物晶型,促进钙离子溶出从而促进碳化反应的进行。该增强技术成本低廉,工艺简单,并且极大地提高了碳化硬化体的机械强度,具有良好的应用前景。
