Dyes for processing refractory wrapping tapes for wires and cables

Abstract

The invention discloses a dye for processing refractory warping tapes of wires and cables and belongs to the field of chemical processing and manufacturing. The dye is mainly prepared from the following raw materials in parts by weight: 25-35 percent of alpha,omega-dihydroxy polydimethylsiloxane, 18-25 percent of polyacrylate emulsion, 6-10 percent of fumed silica, 6-10 percent of alumina, 0.5-2 percent of sintered additive, 1-2 percent of cross-linking agent, 0.1-0.2 percent of catalyst, 5-8 percent of fatty alcohol-polyoxyethylene ether and the balance of water. A ceramic protective layer formed by combustion of the warping tapes processed by using the dye is stable in structure, high in adhesive force and high in compactness, hardly falls off and can easily form a channel so as to achieve the fire-insulated and fireproof effects. Meanwhile, the warping tape processed by using the dye can serve as an auxiliary layer of an insulating sheath, and also has the same flexibility as other types of warping tapes and therefore can be applied to various fields.

Description

technical field [0001] The invention relates to a dye used for processing refractory wrapping tapes of wires and cables, which belongs to the field of chemical processing and manufacturing. Background technique [0002] With the rapid development of economy and society, various types of cable fire accidents occur frequently. Due to the characteristics of rapid spread of cable fire, difficulty in fighting, secondary hazards, and long recovery time, it has brought huge losses to the national economy and the lives and property of the people. Therefore, people pay more and more attention to the fire hazard of wires and cables, and the relevant national departments have higher and higher requirements for performance indicators such as fire resistance and flame retardancy of wires and cables. [0003] The use of fire prevention measures in cables is an important means to reduce the fire and delay of cables. The existing technology includes the method of wrapping the cable with mi...
