Problems solved by technology

[0002] Electrical control is becoming more and more complex, and the demand for cables will inevitably increase accordingly. However, in some special industries, the electromechanical control equipment needs to be placed in a harsh environment, especially in the coal mining industry. As a result of moisture content, stress, and chemical action, the cable will form a "water tree" phenomenon during operation, causing damage to the insulation layer, and discharge will occur at the defect in the sheath, and even break down the cable, causing a fire
Therefore, it is necessary to use flame-retardant tapes in the cable structure of electrical equipment for mining machines to eliminate potential safety hazards. cost

Abstract

The invention discloses a flame-retardant t belt for a cable. The flame-retardant belt comprises a base layer and flame-retardant film layers pressed on the upper side and the lower side of the base layer. The base layer is made of glass fiber composite felt, the flame-retardant film layers are attached to the upper side and the lower side of the glass fiber composite felt in an adhesive mode through pressure-sensitive adhesive, the glass fiber composite felt comprises a glass fiber layer and non-woven cloth layers located on the upper side and the lower side of the glass fiber layer, and the non-woven cloth layers are arranged on the upper side and the lower side of the glass fiber layer through adhesive in a hot-press mode. By means of the mode, the flame-retardant belt can achieve a good flame-retardant function and good acid and alkali resistance through single-layer lapping, and use cost is lowered.

Description

technical field [0001] The invention relates to the field of insulating materials, in particular to a flame-retardant tape for cables. Background technique [0002] Electrical control is becoming more and more complex, and the demand for cables will inevitably increase accordingly. However, in some special industries, the electromechanical control equipment needs to be placed in a harsh environment, especially in the coal mining industry. As a result of moisture content, as well as stress and chemical effects, the cable will form a "water tree" phenomenon during operation, causing damage to the insulation layer, and discharges will occur at the defects in the sheath, and even breakdown the cable, causing a fire. Therefore, it is necessary to use flame-retardant tapes in the cable structure of electrical equipment for mining machines to eliminate potential safety hazards. cost.
