Cement adhesive as well as preparation method and application thereof
The invention provides a cement adhesive as well as a preparation method and application thereof, and belongs to the technical field of cement adhesives. The cement adhesive provided by the invention comprises the following components: aluminate cement, artificial porcelain sand, silica fume, an additive and water, the additive comprises a carbon nanotube, sodium chloride, a water reducing agent and a defoaming agent; the water reducing agent is a polycarboxylic acid water reducing agent. The carbon nanotubes and the sodium chloride can synergistically improve the electrical performance of the cement adhesive, and the synergistic effect of the carbon nanotubes and the sodium chloride in the cement adhesive is mainly reflected in the aspect of improving the electrical conductivity; as a conductive filler, the carbon nanotubes can significantly improve the conductivity of a cement matrix; sodium chloride provides a better dispersion and combination environment for the carbon nanotubes by promoting solidification and hardening of cement, so that a more stable conductive network can be formed, and meanwhile, the dispersity and interface binding force of the carbon nanotubes in a cement matrix can be improved through the coagulation aiding effect of sodium chloride, and the piezoresistive effect of the cement adhesive is optimized.
本发明提供了一种水泥胶合剂及其制备方法和应用，属于水泥胶合剂技术领域。本发明提供的水泥胶合剂包括如下组分：铝酸盐水泥、人工瓷砂、微硅粉、外掺剂和水；所述外掺剂包括碳纳米管、氯化钠、减水剂和消泡剂；所述减水剂为聚羧酸减水剂。本发明中碳纳米管和氯化钠能够协同提高水泥胶合剂的电气性能，碳纳米管和氯化钠在水泥胶合剂中的协同作用主要体现在提高导电性方面；碳纳米管作为导电填料，能够显著提高水泥基体的电导率；氯化钠通过促进水泥的凝固和硬化，为碳纳米管提供更好的分散和结合环境，从而有助于形成更加稳定的导电网络，同时氯化钠的助凝作用有助于改善碳纳米管在水泥基体中的分散性和界面结合力，优化水泥胶合剂的压阻效应。
