Abstract

The invention belongs to the technical field of high-polymer materials, and particularly relates to a method for utilizing glass fibers for preparing flame-retardant cloth. The flame-retardant cloth is prepared from, by mass, 30-40 parts of high-temperature-resistant plasticizer, 50-60 parts of modified glass fibers, 10-20 parts of polyurethane, 10-15 parts of polytetrafluoroethylene, 40-50 partsof bonding agent, 2-3 parts of dispersing agent, 1-2 parts of dyed color master batch and 6-20 parts of flexibilizer. According to the method for utilizing the glass fibers for preparing the flame-retardant cloth, by adjusting the proportion of the modified glass fibers, the high-temperature-resistant plasticizer, polyurethane and polytetrafluoroethylene, optimizing silk yarn manufactured under the processing condition and spraying a layer of compact nanometer-type aluminum trioxide to the surface of the yarn, the yarn achieves the flame-retardant and fireproof effect.

Description

Technical field [0001] The invention belongs to the technical field of polymer materials, and specifically relates to a method for preparing flame-retardant cloth by using glass fiber. Background technique [0002] In the patent number CN 107849760 A, it is disclosed that the present invention provides a glass fiber fabric, which has good weaving properties, can reduce the thickness and can suppress the generation of gaps between longitudinal and transverse filaments, and is used to make prepreg The material can suppress warpage and microporosity. The glass fiber fabric is composed of longitudinal filaments and horizontal filaments. The glass fiber fabric has a thickness in the range of 7 to 14 μm, a mass in the range of 7 to 14 g per 1 m2, and an air permeability in the range of 20 to 220 cm3 / cm2 / sec. The horizontal yarn is made up of multiple glass filaments with substantially the same average diameter in the range of 3.5 to 4.4 μm, and the longitudinal and horizontal yarns ha...
