Preparation method of high-temperature-resistant and fire-proof carbon fiber cloth

Abstract

The invention discloses a preparation method of high-temperature-resistant and fire-proof carbon fiber cloth. The preparation method is characterized by comprising the steps as follows: (1) blending: all fiber materials are blended and woven into carbon fiber cloth; (2) cleaning and drying: the carbon fiber cloth is immersed in a cleaning fluid for heated cleaning, taken out and dried until the moisture content is 7%-10%; (3) surface reduction: the carbon fiber cloth is subjected to a reduction reaction in a reaction kettle by use of CO gas; (4) impregnation treatment: the reduced carbon fiber cloth is immersed in an impregnation liquid for impregnation treatment; (5) plasma treatment: the carbon fiber cloth is placed in a plasma treatment machine for plasma treatment and subjected to secondary impregnation; (6) oxidation treatment: ozone is introduced into the reaction kettle and oxidation treatment of the carbon fiber cloth is carried out. The prepared carbon fiber cloth has good fire resistance, has better shielding effects on ultraviolet and sunlight and has a deodorization function.

Description

technical field [0001] The invention belongs to the technical field of textile processing, and in particular relates to a method for preparing a high-temperature-resistant and fire-resistant carbon fiber cloth. Background technique [0002] Carbon fiber is a new type of high-strength and high-modulus fiber with a carbon content of more than 95%. It has the characteristics of light weight and high strength, and is widely used in important fields of national defense and civilian use; It also has the softness and processability of textile fibers, and has high axial strength and modulus, low density and high specific performance. According to the different classification of carbon fiber, carbon fiber can be mainly divided into: high strength, high modulus carbon fiber, ion exchange carbon fiber and activated carbon fiber; according to different raw materials, carbon fiber can be divided into pitch base, viscose base, polyacrylonitrile base and wood There are four types of plain...
