Cement adhesive for large-tonnage glass insulator
The invention discloses a cement adhesive for a large-tonnage glass insulator. The cement adhesive is composed of the following components in percentage by weight: 40-60% of cement, 15-30% of cementing sand, 3-10% of silica fume, 0.03% of anti-cracking fiber, 5-20% of micro powder, 0.03-0.08% of plastic retaining agent, 0.2-1.0% of water reducing agent and 7-12% of water. According to the invention, the water-binder ratio is reduced, the problem of low fluidity is solved, the slurry compactness is increased, the strength of the cement adhesive is improved, the cement adhesive is used on a batch production line, the production and binding process requirements are met, the appearance defects such as bubbles, cracks and the like on the surface of the product are avoided, and the mechanical property requirements of 420-1000kN large-tonnage glass insulator products are met.
本发明公开了一种大吨位玻璃绝缘子用水泥胶合剂，由以下重量百分比的组分组成，其中，水泥40‑60%，胶装砂15‑30%，硅灰3‑10%，抗裂纤维0.03%，微粉5‑20%，保塑剂0.03‑0.08%，减水剂0.2‑1.0%，水7‑12%。本发明不仅降低了水胶比，同时解决了流动度偏低的问题，增加了浆体密实性，提高了水泥胶合剂强度，在批量化生产线上使用，满足生产胶装工艺要求，且产品表面无气泡、裂纹等外观缺陷，满足420‑1000kN大吨位玻璃绝缘子产品机械性能要求。
