Cement adhesive for porcelain insulator and preparation method thereof
The invention provides a cement adhesive for a porcelain insulator and a preparation method of the cement adhesive, and belongs to the technical field of electric extra-high voltage. The cement adhesive for the porcelain insulator consists of a main material and an additive, the main material consists of the following components in percentage by mass: 40-60 wt% of aluminoferrite cement, 35-55 wt% of copper slag and the balance of silica powder, and the total percentage is 100%; the admixture is composed of calcium sulfate whiskers, an anti-cracking agent, a water reducing agent, a shrinkage reducing agent and a defoaming agent; the addition amount of the calcium sulfate whiskers is 5-20wt% of the mass of the main material, the addition amount of the anti-cracking agent is 0.1-0.2 wt% of the mass of the main material, and the addition amount of the water reducing agent is 0.1-0.3 wt% of the mass of the main material; the addition amount of the shrinkage reducing agent is 0.1-0.3 wt% of the mass of the main material; the addition amount of the defoaming agent is 0.2-0.3 wt% of the mass of the main material. The cement adhesive is reasonable in material selection, and the prepared cement adhesive is good in fluidity, high in mechanical property and low in elasticity modulus.
本发明提供了一种瓷绝缘子用水泥胶合剂及其制备方法，属于电力特高压技术领域。瓷绝缘子用水泥胶合剂由主料和外掺剂组成；主料由以下质量百分比的组分组成：40～60wt％的铁铝酸盐水泥，35～55wt％的铜矿渣，其余为硅微粉，合计为100％；外掺剂由硫酸钙晶须、抗裂剂、减水剂、减缩剂和消泡剂组成；硫酸钙晶须的添加量为主料质量的5～20wt％，抗裂剂的添加量为主料质量的0.1～0.2wt％，减水剂的添加量为主料质量的0.1～0.3wt％；减缩剂的添加量为主料质量的0.1～0.3wt％；消泡剂的添加量为主料质量的0.2～0.3wt％。本发明选材合理，制备的水泥胶合剂流动性好、力学性能高、弹性模量较低。
