Antistatic mortar
The invention discloses an antistatic mortar. The antistatic mortar comprises the following raw materials in parts by weight: 5 to 20 parts of Portland cement; 10 to 20 parts of quartz sand; 10 to 20parts of anti-static conductive sand; 0.5 to 2.0 parts of modified carbon fiber, 0.5 to 2.0 parts of redispersible latex powder, 0.05 to 0.10 part of cellulose ether, 0.15 to 0.25 part of a water reducing agent, 0.2 to 0.5 part of a defoaming agent, 1.5 to 3.5 parts of an early strength agent, 0.05 to 0.10 part of a retarder, 1 to 2 parts of a volume stabilizer, and 0.1 to 0.2 part of a thixotropic agent. According to the invention, raw materials are selected, and content is adjusted; particularly, the contents of the modified carbon fiber and the anti-static conductive sand are adjusted, andthe modified carbon fiber and the anti-static conductive sand are matched with each other in the mortar and interact with other functional aids, so that the surface resistance range of the mortar meets the anti-static use requirements of different projects, and good physical and mechanical properties are ensured.
本发明公开了一种防静电砂浆，包括以下按重量份数计的原料：硅酸盐水泥5‑20份、石英砂10‑20份、防静电导电砂10‑20份、改性碳纤维0.5‑2.0份、可再分散乳胶粉0.5‑2.0份、纤维素醚0.05‑0.10份、减水剂0.15‑0.25份、消泡剂0.2‑0.5份、早强剂1.5‑3.5份、缓凝剂0.05‑0.10份、体积稳定剂1‑2份，触变剂0.1‑0.2份。本发明通过原材料的选择和含量调整，尤其是利用改性碳纤维和防静电导电砂的含量调整，两者在本发明砂浆中相互配合，并与其他功能助剂相互作用，使得本发明砂浆表面电阻范围满足不同工程的防静电使用要求，并确保具有良好的物理力学性能。
