Preparation method of high-temperature-resistant protective isolation pad

Abstract

The invention discloses a preparation method of a high-temperature-resistant protective isolation pad. The method comprises: carrying out mixing soaking on glass fibers and a sodium hydroxide solutionaccording to a mass ratio of 1:8-1:18, filtering, washing, and drying to obtain primarily treated glass fibers; weaving the primarily treated glass fibers and a graphene fiber layer, and carrying outthermal compounding on an aluminum foil and the glass fiber cloth through a flame-retardant adhesive by adopting a thermal compounding machine to prepare a primary glass fiber cloth; carrying out ultraviolet curing to prepare a basic glass fiber cloth; laminating the basic glass fiber cloth and a high-temperature-resistant surface cloth through a laminating device to obtain the high-temperature-resistant glass fiber cloth; drying the laminated high-temperature-resistant glass fiber cloth through a drying device; and slitting into specified specifications to obtain the high-temperature-resistant protective isolation pad. According to the high-temperature-resistant protective isolation pad, the characteristics of the high-temperature-resistant protective isolation pad are improved, the heatpreservation surface is flat and uniform, the heat preservation quality is guaranteed, the overall energy-saving effect is also improved, and social and economic benefits are remarkable.

Description

technical field [0001] The invention relates to the technical field of glass fiber cloth, in particular to a preparation method of a high temperature resistant protective isolation pad. Background technique [0002] At present, some conventional high-temperature-resistant protective isolation pads have low temperature resistance, and are generally hot-pressed and laminated with polyethylene, and then used as a veneer for thermal insulation materials. In some high-temperature occasions, such as high-temperature steam pipelines, there are high requirements for the temperature resistance of aluminum foil glass fiber cloth, which cannot be achieved by conventional products. In the construction of pipelines, the on-site insulation workload is heavy, the materials are wasted, the packaging form is complex and not firm, and the site is damp and easily corroded, and the moisture in the insulation materials cannot be released due to airtightness, and the insulation quality cannot be ...
