Preparation method of ultra-dispersed silylene concrete reinforcing agent
The invention discloses a preparation method of an ultra-dispersed silylene concrete reinforcing agent, which comprises the following steps: adding deionized water, a dispersing agent and a silane coupling agent into a three-neck flask, fully dissolving, adding silylene into the flask, controlling the system temperature to be 20-50 DEG C, starting stirring, controlling the stirring speed to be 800-1400 rpm, and continuously reacting for 48-72 hours to obtain a light yellow colloidal dispersion solution; the final ultra-dispersed silylene concrete reinforcing agent is obtained. The prepared ultra-dispersed silylene concrete reinforcing agent can rapidly promote cement hydration, shorten the setting time and greatly improve the compressive strength and breaking strength of a concrete material.
本发明公开了一种超分散硅烯混凝土增强剂的制备方法，包括：向三口烧瓶中加入去离子水和分散剂、硅烷偶联剂充分溶解后，向瓶中加入硅烯，控制体系温度为20℃~50℃，开启搅拌，搅拌速率控制为800 rpm~1400 rpm，持续反应48 h~72 h，得到浅黄色胶体分散溶液，即为最终超分散硅烯混凝土增强剂。本发明制备的超分散硅烯混凝土增强剂能迅速促进水泥水化，缩短凝结时间，大幅度提升混凝土材料的抗压强度和抗折强度。
