Problems solved by technology

The strength of electric porcelain products after gluing mainly depends on two factors. On the one hand, the strength of the electric porcelain body itself, and another important factor is the bonding strength between the porcelain parts and the metal flange. The bonding strength depends on The strength of the cement mortar adhesive, if the bonding strength is low, the joint between the porcelain part and the flange will be prone to breakage under the action of external force. Therefore, it is necessary to develop a high-strength inorganic adhesive for high-voltage electric porcelain bonding Gelling materials, while traditional inorganic gelling materials form an acidic environment in the solution under hydrotrophic conditions, which in turn leads to partial dissolution of the target product and gel, forming pores and cracks on the surface and inside of the slurry, resulting in a decrease in structural density , the porosity increases, the water resistance is not good, and the strength decreases

Abstract

The invention discloses a composite cementitious material for bonding high-voltage electric porcelain, comprising the following raw materials in parts by weight: 60-80 parts of cement, 5-10 parts of quartz sand, 1-3 parts of water reducer, 5-10 parts of nano-oxidized 1-10 parts of mineral fibers, 3-10 parts of heterocyclic compounds, 5-10 parts of organic solvents and 10-50 parts of water, the present invention can prevent the further dissolution of by-products and target products in the cement hydration stage, The original structure of the inorganic gelling material is kept from being destroyed, thereby improving the later strength of the inorganic gelling material. The invention also discloses a preparation method of the inorganic gelling material. Heterocyclic compounds can form network structures and film layers in different hydration stages of cement, improving the water resistance of inorganic cementitious materials.

Description

technical field [0001] The invention relates to the field of electric porcelain, in particular to a composite gelling material for bonding high-voltage electric porcelain and a preparation method thereof. Background technique [0002] Cement glue, porcelain parts and metal accessories are also called the three major components of glue-mounted insulators. Cement glue plays an important role in the overall structure and connection of insulators, and is directly related to the performance, life and reliability of insulators. The strength of electric porcelain products after gluing mainly depends on two factors. On the one hand, the strength of the electric porcelain body itself, and another important factor is the bonding strength between the porcelain parts and the metal flange. The bonding strength depends on The strength of the cement mortar adhesive, if the bonding strength is low, the joint between the porcelain part and the flange will be prone to breakage under the acti...
