Embodiment 1
[0025] Step 1: Prepare sulfonic acid polyethersulfone. Concentrated sulfuric acid is used as sulfonating agent and solvent simultaneously, and the following parts are parts by mass. 100 parts of 98% concentrated sulfuric acid dissolves 20 parts of polyethersulfone resin and carries out sulfonation modification at the same time, introducing sulfonic acid groups into the p-phenylene molecular chain of polyethersulfone. Stir mechanically, the reaction temperature is 30°C, and the reaction time is 6 hours.
[0026] Step 2: Wash with water to remove solvent. Wash the product with a large amount of first-grade distilled water until the pH is 6-8 to ensure that there is no sulfuric acid residue, otherwise it will affect the determination of the degree of sulfonation; when the pH value is stable, dry it, and after repeated tests to determine that it is completely dry, store it in an airtight dry place ; The degree of sulfonation is 4.3%.
[0027] Step 3: Configuration of sulfonated...
Embodiment 2
[0034] Step 1: Prepare sulfonic acid polyethersulfone. Concentrated sulfuric acid is used as sulfonating agent and solvent simultaneously, and the following parts are parts by mass. 200 parts of 98% concentrated sulfuric acid dissolves 16 parts of polyethersulfone resin and performs sulfonation modification at the same time to introduce sulfonic acid groups into the p-phenylene molecular chain of polyethersulfone. Stir mechanically, the reaction temperature is 30°C, and the reaction time is 6 hours.
[0035] Step 2: Wash with water to remove solvent. Wash the product with a large amount of first-grade distilled water until the pH is 6-8 to ensure that there is no sulfuric acid residue, otherwise it will affect the determination of the degree of sulfonation; when the pH value is stable, dry it, and after repeated tests to determine that it is completely dry, store it in an airtight dry place ; The degree of sulfonation is 18.0%.
[0036] Step 3: Same as steps 3-6 in Example ...
Embodiment 3
[0039] Step 1: Same as Step 1-2 of Example 1.
[0040]Step 2: Configuration of sulfonated polyethersulfone sizing agent. Dissolve 0.1723 g of sulfonic acid polyethersulfone in 200 ml of solvent, wherein the solvent is a mixed solution of dimethylacetamide and ethanol, and the mass ratio of the two is 1:1. A sulfonic acid-based polyethersulfone sizing agent was obtained.
[0041] Step 3: Polyacrylonitrile-based carbon fiber sizing. Pour the sulfonic acid-based polyethersulfone sizing agent sample obtained in step 2 into the sizing tank, pass the carbon fiber through the sizing tank at an average speed, impregnate the wire at a speed of 10cm / s, dry and close the wire to obtain the sized carbon fiber .
[0042] Step 4: Preparation of sized carbon fiber composite polyethersulfone splines. Weigh 5g of polyethersulfone resin and dissolve it in 17.4ml of solvent, the solvent is a mixture of dimethylacetamide and ethanol, the mass ratio of the two is 1:1. A polyethersulfone resin...
