Abstract

The invention relates to a ceramic silicon rubber glass fiber composite insulating rubber for welding machine transformers and other transformer winding wires. D. ₄ , vinyl silicone oil, zinc oxide, sodium bisilicate, quartz powder, muscovite powder, phlogopite powder, melamine, cerium hydroxide, 4# fumed carbon black, superfine calcined clay, hydroxyl silicone oil, surface treatment The base rubber is kneaded at room temperature, and then vulcanized by adding a vulcanizing agent and vulcanized on an open mill. The beneficial effects of the present invention are: 1. Fire resistance, high and low temperature resistance, odorless, non-toxic, non-corrosive, and little negative impact on the environment; 2. High insulation, high resistance to compression deformation and excellent low-temperature elasticity; 3. The production process is simple and safe, the production speed is high and the efficiency is high, and the product is easy to realize.

Description

technical field [0001] The invention relates to a ceramicized silicone rubber glass fiber composite insulating rubber for electric welding machine transformers and other transformer winding wires. Background technique [0002] At present, most of the transformer winding wires of domestic AC arc welding machines use glass fiber wires. In the production process, it is necessary to heat and dry the wires after winding glass fiber wires with multiple layers and impregnating insulating varnish. Its disadvantages are: 1. It is easy to produce quality defects such as missing strands, broken strands, loose strands and fiber gap insulating paint filling, uneven bonding, and easy falling off; 2. Slow production speed, low efficiency, and organic solvent emission odor 3. The thermal stability, oxidation resistance, wear resistance, solvent resistance and arc resistance of the winding insulation layer are poor, and the breakdown strength is low, so it is difficult to ensure the safety a...
