Abstract

The invention discloses an early-strength insulator cement adhesive, which is prepared from the following raw materials in percentage by weight: 30%-40% of P.O52.5 portland cement, 35%-50% of sand, 0.4%-1.0% of a water reducing agent, 5%-15% of a mixed mineral admixture and 9%-15% of water, wherein the mixed mineral admixture contains activated silica powder; the activated silica powder is a powder product which is obtained by grinding and grading treatment of siliceous rock which is deposited by volcanic ash; the mean particle size d is 1.53 microns; and the other components are one or two of superfine slag powder and coal ashes. The cement adhesive has relatively high fluidity, also has certain cohesiveness, and is convenient to bind manually; the adhesive binding efficiency and quality are improved; the operation performance of the cement adhesive is fundamentally guaranteed; meanwhile, the early-strength insulator cement adhesive also has the characteristics of high early strength and high late development strength; and the cement adhesive for electrical porcelain binding has excellent overall performance.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an early-strength insulator cement adhesive. Background technique [0002] With the rapid growth of my country's economy and the continuous development of electric power construction, large-span, long-distance, low-loss, and UHV transmission lines have been rapidly popularized. More widely, insulators are indispensable insulation equipment for power systems, mainly playing the role of mechanical connection and electrical insulation. As an important link in the insulator manufacturing process, the plastic packaging of insulators has also received more and more attention. The quality of the cement glue used for insulator binding is an extremely important factor, which directly affects the quality of the insulator, and then affects the entire power transmission and transformation project. [0003] Cement adhesive is an important part of electric porcelain products, mai...
