specific Embodiment approach 1

[0014] Embodiment 1: In this embodiment, a method for improving the anti-ultraviolet performance of M5 fiber by tubular titanium dioxide is carried out through the following steps:

[0015] 1. M5 fiber pretreatment: add KH-550 to the three-necked bottle, add deionized water drop by drop within 30 minutes, adjust the pH value to 2-5, put the M5 fiber into the solution, and keep the temperature at 45°C-55°C Take it out after reacting for 3h-4h under certain conditions, and place it at room temperature for 12h-24h to obtain the pretreated M5 fiber; the mass ratio of KH-550 to deionized water is 1:(0.4-0.5)

[0016] 2. Preparation of tubular titanium dioxide: dissolve anatase titanium dioxide in a NaOH solution with a concentration of 1mol / L-2mol / L, stir in an oil bath environment with a temperature of 120°C-140°C for 24h-36h, and then use a concentration of wash repeatedly with 0.1mol / L-0.5mol / L hydrochloric acid and distilled water, adjust the pH value to 7, and finally dry in a...

specific Embodiment approach 2

[0021] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the mass ratio of KH-550 to deionized water in step 1 is 5:1. Others are the same as the first embodiment.

specific Embodiment approach 3

[0022] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the pH value is adjusted to 4 in step 1. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

A method of improving an anti-ultraviolet performance of M5 fibers with tubular titanium dioxide. The invention relates to the method of improving the anti-ultraviolet performance of the M5 fibers with the tubular titanium dioxide and aims to solve a problem that M5 fibers is poor in the anti-ultraviolet performance and is liable to damage when being irradiated by light in the prior art. The method includes following steps: preparing the tubular titanium dioxide, supporting the tubular titanium dioxide onto acidized sericite to prepare coating slurry, soaking the M5 fibers in KH-550 to enhance the activity of the M5 fibers, and finally soaking the M5 fiber in the slurry to obtain the M5 fibers coated with tubular titanium dioxide. The method is used for improving the anti-ultraviolet performance of the M5 fibers.

Description

technical field [0001] The invention relates to a method for improving the anti-ultraviolet performance of M5 fiber by tubular titanium dioxide. Background technique [0002] M5 fiber is a liquid crystal aromatic heterocyclic polymer poly[2,5-dihydroxy-1,4-phenylenepyridinediimidazole] fiber, which has excellent mechanical properties and bonding properties, and its high resistance characteristics are due to carbon fibers, while The compression resistance is higher than that of PBO fiber, so it has great competitiveness in the field of high-performance fiber composite materials. Due to the advanced nature of M5, it has better adhesion to the resin, so it also has advantages over other fibers. However, the current weakness of M5 fiber in terms of UV resistance still limits its application. Contents of the invention [0003] The invention aims to solve the problems that the existing M5 fiber has low ultraviolet resistance and is easily damaged by light, and provides a metho...
