High-flame-retardant fire isolation and oxygen isolation glass cloth covering belt

Abstract

The invention relates to a high-flame-retardant fire isolation and oxygen isolation glass cloth covering belt, which belongs to the technical field of electrician insulation materials. The high-flame-retardant fire isolation and oxygen isolation glass cloth covering belt is mainly characterized in that medium-alkali glass fiber cloth is used as base cloth, the medium-alkali glass fiber cloth is treated by a soaking coating curing work procedure for soaking glue materials into base cloth, in addition, excessive slurry is removed, and slitting is carried out after the drying; the glue materials are obtained in the way that heat absorption fire-retardant agents of magnesium hydrate and water are put into a stirring kettle according to a mass ratio being 1:2 to be stirred for at least 30 minutes, and then, copolymer emulsion glue with the same weight as the magnesium hydrate is added to be stirred for 10 minutes until the materials are uniform. The glue materials soaking the base cloth are nonflammable at high temperature, in fire hazards, the passing of flame can be prevented, the insulation layer is protected from burning, the high-flame-retardant fire isolation and oxygen isolation glass cloth covering belt has the characteristics that the folding fracture cannot easily occur, the property is soft, the winding and covering effect is flat, and the like, and moisture is prevented from invading into the insulation layer in the operation process. The medium-alkali glass fiber cloth is inorganic fiber and has the characteristics that inflammability is realized, the water absorption performance is small, the tensile strength is high, the elastic factor is high, and the like. During the glass cloth belt production, glass silks and chips can be effectively prevented from being generated in the production process through the glue material soaking, and the work environment is effectively improved.

Description

technical field [0001] The invention relates to a high flame-retardant, fire-proof and oxygen-proof glass cloth wrapping tape, which is suitable for cable wrapping and belongs to the technical field of cable insulating materials. Background technique [0002] Most of the existing cable wrapping tapes are made of non-woven fabrics, which have a low oxygen index, are easy to burn, have no flame retardant function, and cannot achieve the purpose of preventing combustion. The cable wrapping tape of fire-resistant cables, this kind of glass fiber tape is easy to produce flying glass filaments and chips when it is cabled and wrapped. The flying objects will pollute the environment. Skin allergies. Contents of the invention [0003] The object of the present invention is to provide a high flame-retardant, fire-proof and oxygen-insulating glass cloth wrapping tape, which can solve the above-mentioned shortcomings in the existing cable wrapping tapes, and the present invention is ...
