The invention relates to an insulator production material, in particular to a formulation of a cement adhesive for a porcelain insulator and a metal accessory. The cement adhesive is composed of the following mixed components in parts by weight: 100 parts of sulfate aluminum cement, 95-105 parts of cementing quartz sand, 27 parts of water and 0.4-0.5 part of water reducing agent, wherein the fineness of the sulfate aluminum cement granules is not larger than 0.09 mm, 0.3-1 mm granules in the cementing quartz sand are larger than 80%, the pH value of the water is 7.0-7.2, and the water temperature is lower than 35 DEG C; and by adopting the cement adhesive for porcelain insulator and metal accessory provided by the technical scheme of the invention, the early strength of the adhesive can be improved, the cost is reduced, and about ***Yuan can be saved for each ton.
Description
technical field [0001] The invention relates to a material for insulator production, in particular to a formula of cement adhesive for porcelain insulators and metal accessories. Background technique [0002] With the continuous development of my country's electric power construction, ultra-high voltage, long-span, and long-distance power transmission have been rapidly popularized, and electric porcelain products, which play an important role in power transmission and transformation projects, are widely used. [0003] Cement adhesive is an important part of electric porcelain products, mainly used in porcelain insulators such as suspension type and line post type, and it plays the role of integrating porcelain parts and metal accessories into a whole. In the prior art, electric porcelain products have the following problems in glue binding: the early strength of the adhesive after the product is glued is small, which seriously affects the production efficiency; in addition, ...
