[0025]Weigh 300g of ordinary glass and put it into a pulverizer and pulverize it for 10 minutes to obtain pulverized glass. Put the pulverized glass into a kiln at 800 °C for 1 hour to obtain a molten liquid. Draw wire at 2000r / min to obtain the self-made glass fiber precursor. Mix the self-made glass fiber precursor and cyanate ester resin according to the mass ratio of 4:1 and grind for 8min to obtain the modified glass fiber. Weigh 12g magnesium hydroxide and 10g The aluminum hydroxide was mixed and poured into a beaker with 45mL of deionized water, and the beaker was placed in a water bath, mixed and stirred at 55°C for 16min, and then 4g of titanate coupling agent TMC-201 was added after stirring, and the temperature was continued. The reaction was carried out for 45 minutes, and finally put into an oven, and dried at 90 ° C for 8 minutes to obtain a self-made modified powder cake. 30 g of river sand was weighed, ground and pulverized for 6 minutes, and then passed through...

[0027] Weigh 350g of ordinary glass into a pulverizer and pulverize for 11 minutes to obtain pulverized glass. Put the pulverized glass into a kiln at 900°C for 1.5 hours to obtain a molten liquid. After removing bubbles, transport it to a porous leakage plate. Draw wire at 2200 r / min to obtain self-made glass fiber precursors, mix the homemade glass fiber precursors and cyanate ester resin with a mass ratio of 4:1 and grind for 9 minutes to obtain modified glass fibers. Weigh 14g of magnesium hydroxide and cyanate ester resin. 11g of aluminum hydroxide was mixed and poured into a beaker with 55mL of deionized water, and the beaker was placed in a water bath, mixed and stirred at 65°C for 18min, and then 5g of titanate coupling agent TMC-201 was added after stirring, and continued Incubate the reaction for 53 minutes, put it in an oven at last, and dry it at 95°C for 9 minutes to obtain a self-made modified powder cake. Weigh 35 g of river sand, grind and pulverize it for 8 min...

[0029] Weigh 400g of ordinary glass and put it into a pulverizer and pulverize it for 12 minutes to obtain pulverized glass. Put the pulverized glass into a kiln at 1000°C and melt for 2 hours to obtain a molten liquid. Draw wire at 2400r / min to obtain the self-made glass fiber precursor. Mix the self-made glass fiber precursor and cyanate ester resin according to the mass ratio of 4:1 and grind for 10min to obtain the modified glass fiber. Weigh 16g magnesium hydroxide and 12g hydrogen The alumina was mixed and poured into a beaker with 65 mL of deionized water, and the beaker was placed in a water bath, mixed and stirred at 75 ° C for 20 min, and then 6 g of titanate coupling agent TMC-201 was added after stirring, and the reaction was continued. 60min, finally put it in an oven, and dried at 100°C for 10min to obtain a self-made modified powder cake. Weigh 40g of river sand, grind and pulverize it for 10min, pass it through a 100-mesh sieve, collect the sieved river sand pow...
