Abstract

The invention relates to a glass insulator material. An existing insulator is poor in insulation performance of high-alkali glass. The glass insulator material comprises components by weight of 65-72% of SiO2, 0.05-4% of PbO, 2-8% of Al2O3, 2-6% of MgO, 6-12% of Na2O, 3-8% of K2O, 0.5-2% of BaO, 0-0.4% of Li2O and 0.5-1.5% of SrO. When the glass insulator material is 18 DEG C, the volume resistivity is larger than 5*1014. When the glass insulator material is 90 DEG C, the volume resistivity is larger than 2*1010. When the glass insulator material is 18 DEG C, the dielectric loss D is smaller than 1.4%. When the glass insulator material is 40 DEG C, the dielectric loss is smaller than 2.0%. The glass insulator material uses waste leaded glass as main raw materials, changes waste into wealth, and achieves resource utilization of leaded glass. Furthermore, the glass insulator material is high in volume resistivity, low in dielectric loss and excellent in sealing performance and processing performance.

Description

Technical field [0001] The invention relates to a glass insulator material, in particular to an insulator glass piece prepared by using waste lead-containing glass as a raw material. Background technique [0002] An insulator is a device mainly used to support and insulate the wires of overhead transmission lines. The insulators currently used mainly include porcelain insulators, glass insulators and organic composite insulators. Traditional porcelain insulators have complex manufacturing processes, high energy consumption, bulky and fragile products, and poor tensile and bending strength. In addition, the porcelain surface is hydrophilic and therefore has poor resistance to pollution flashover. Organic composite insulators are light in weight, have good anti-fouling performance, and have high strength. The disadvantage is that the production cost is relatively high. Compared with ceramic and organic composite insulators, glass insulators have extremely obvious advantages and h...
