Abstract

The invention relates to silicate cement adhesive for a high-voltage electrical appliance bushing. The adhesive is prepared by combining and proportioning the following raw materials in percentage by weight: 30-45 percent of silicate cement, 25-50 percent of silica sand, 1.0-5.5 percent of water reducing agent, 0.1-2.0 percent of early strength agent and the balance of water, wherein the water reducing agent is of high-efficiency and reaches the water reducing effect of 25-50 percent to satisfy the high-mobility requirement and the strength requirement of the silicate cement for a bushing, the compactness and the early strength of the cement are enhanced by the early strength agent, and the production efficiency is improved. The invention adopting a formula of the raw materials and the proportion has excellent process performance and reasonable mechanical performance and satisfies the binding condition and the use safety requirement of the bushing.

Description

technical field [0001] The invention relates to a Portland cement adhesive for high-voltage electric appliance porcelain bushings (hereinafter referred to as porcelain bushings). More specifically, the present invention relates to a Portland cement adhesive for porcelain sleeves with high water-reducing properties, high fluidity, high strength and other excellent properties. Background technique [0002] With the continuous development of my country's electric power construction, more and more large-scale porcelain sleeves, which play an important role in power transmission and transformation projects, are used, and the plastic packaging of porcelain sleeves is also more and more valued by people. [0003] Cement adhesive is an important part of electric porcelain products, and it plays a role in integrating porcelain parts and metal accessories into a whole. In the prior art, there are the following problems in glue binding of large-scale porcelain sleeves: the fluidity of...
