Problems solved by technology

However, after the glass fiber is woven into a fabric, due to the pores in the ordinary glass fiber fabric, after being heated, hot air, flames and radiation can pass through the pores in the fabric to the back of the fabric; some sparks or molten iron splash into the fabric. Glass fiber fabric can be embedded in the pores of the fabric after being applied, which is easy to cause harm to human body or facilities

Abstract

The invention provides a heat-insulating and ablation-resistant glass fiber fabric and a preparation method thereof, belonging to the technical field of thermal protection fabrics and preparation thereof. The heat-insulating and ablation-resistant glass fiber fabric product comprises a fabric layer and coating layers on the front and back surfaces of the fabric layer, wherein the thicknesses of the coating layers on the front and back surfaces of the fabric layer are controlled at 30-80 micros; the fabric layer is made from glass fiber fabrics; the coating layers are composite organic silicon resin coating layers which are prepared by mixing an organic silicon resin solution, white carbon black, mica powder and the like in certain percentage by weight; a solute of the organic silicon resin solution is phenyl methyl silicone, a solvent of the organic silicon resin solution is dimethylbenzene, toluene or a mixture of the two, and the mass ratio of the solvent to the solute is 1:1; and a preparation method of a composite organic silicon resin coating layer solution comprises the following steps of: sequentially adding the white carbon black, the mica powder, wollastonite in powder and metallic oxide into the organic silicon resin solution, and stirring to ensure that the substances are uniformly dissolved. The heat-insulating and ablation-resistant glass fiber fabric is simple in process, easy to operate, and excellent in heat resistance, weather resistance, insulating property, reinforcement performance, scrubbing resistance and weathering resistance.

Description

technical field [0001] The invention relates to a thermal protection fabric and its preparation technology, in particular to a heat-insulating and ablation-resistant glass fiber fabric and its preparation method. Background technique [0002] Heat-protective fabrics refer to special fabrics that can shield and reflect the heat emitted by high-temperature heat sources, so that the backside can still maintain a lower temperature, thereby protecting the human body or facilities from harm. Heat insulation and ablation resistance are important protective properties of thermal protective fabrics. In actual use, thermal protective fabrics with thermal insulation and ablation resistance can provide a protective barrier between the external flame and the user, preventing the user from directly Contact with the flame, and block the external heat from being transmitted to the user in the form of heat convection, heat radiation, and heat conduction, so as to ensure its safe operation in...
