Medium and high strength insulator material formula and preparation method thereof

Abstract

The invention provides a medium and high strength insulator material formula, which comprises 12 to 18 parts of banshan mud, 12 to 16 parts of jiangchong mud, 13 to 18 parts of Changfeng mud, 12 to 17parts of morantang mud, 16 to 23 parts of Guangdong mud, 3 to 9 parts of Fujian mud, 4 to 8 parts of bauxite, 5 to 11 parts of Zuoyun soil and 3 to 10 parts of Hubei mud. A large amount of clay or feldspar with high plasticity and high binding force in the traditional formula are not needed, the firing temperature of a blank is reduced to 1280-1320 DEG C, and energy is saved. A glaze pouring method is adopted, and glazing is fast and pollution-free. The medium and high strength insulator material can still ensure high mechanical strength and puncture resistance under the condition of higher sodium ion content (1-5%). Compared with the traditional process, the total cost of the medium and high strength insulator material is saved by about 45%, the production period is shortened by about 20%, and the prepared insulator has uniform porcelain structure, small dispersibility and high mechanical strength and electrical strength.

Description

technical field [0001] The invention relates to the technical field of porcelain insulator preparation, in particular to a medium-high strength insulator material formula and a preparation method thereof. [0002] The percentages involved in the present invention are all mass fractions. Background technique [0003] An insulator is a device installed between conductors of different potentials or between a conductor and a component at ground potential, capable of withstanding voltage and mechanical stress. An insulator is a special insulation control that plays two basic roles in overhead transmission lines: it is used to support and fix the busbar and live conductors, and to provide sufficient distance and insulation between live conductors or between conductors and the earth. Insulators are used to increase the creepage distance, commonly used are porcelain insulators and fiberglass insulators. [0004] Electric porcelain billet refers to a mixture of clay raw materials, ...

AI Technical Summary

Problems solved by technology

Some raw materials need to be washed to meet the process requirements, which increases the manufacturing cost and has the potential risk of polluting the environment

[0006] Most of the existing processes adopt the method of spraying glaze, which is difficult to clean the atomized glaze slurry, and there is a problem of serious environmental pollution; the quality of the glaze surface is difficult to control, and defects such as flower glaze, crystallization, and uneven glaze surface are prone to occur, thereby Affect the electrical performance of the product

At the same time, in the glaze spraying stage, it is necessary to repeatedly heat and dry the blank and spray glaze. Each heating and drying takes about 24 hours, the production cycle is long, and the energy consumption is high.
