Embodiment 1
[0044] Add 80ml deionized water and 4g APP into the three-necked flask, heat to 75°C, and stir thoroughly for 1 hour to obtain APP suspension.
[0045] Add 1g of CMSs, 0.5ml of glacial acetic acid, 1ml of KH-550 and 50ml of absolute ethanol into a beaker, and perform silanization reaction at 30°C for 30min.
[0046] Pour the above-prepared silanized modified CMSs reaction dispersion into the APP suspension, reflux at 80° C. for 2 h, and pour off the supernatant to obtain a crude CMSs-APP product.
[0047] The CMSs-APP crude product was dried at 80°C for 12h, ground, washed several times with absolute ethanol to remove unreacted KH-550 and other impurities, and then dried at 80°C for 12h to prepare the CMSs-APP flame retardant.
[0048] The above results were verified by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). figure 1 The morphology diagram of the raw material CMSs is given, which shows that the CMSs are spherically distributed, with smoot...
Embodiment 2
[0058] Add 80ml of deionized water and 2g of APP into the three-necked flask, heat to 80°C, and stir thoroughly for 1 hour to obtain APP suspension.
[0059] Add 1g of CMSs, 1ml of glacial acetic acid, 1.5ml of KH-550 and 50ml of absolute ethanol into a beaker, and perform silanization reaction at 40°C for 40min.
[0060] Pour the above-prepared silanized modified CMSs reaction dispersion into the APP suspension, reflux at 85° C. for 3 h, and pour off the supernatant to obtain a crude CMSs-APP product.
[0061] The CMSs-APP crude product was dried at 90°C for 18h, ground, washed several times with absolute ethanol to remove unreacted KH-550 and other impurities, and then dried at 90°C for 12h to prepare the CMSs-APP flame retardant.
Embodiment 3
[0066] Add 100ml of deionized water and 1g of APP into the three-necked flask, heat to 85°C, and stir thoroughly for 1 hour to obtain APP suspension.
[0067] Add 1g of CMSs, 1.5ml of glacial acetic acid, 2ml of KH-550 and 50ml of absolute ethanol into a beaker, and perform silanization reaction at 50°C for 50min.
[0068] Pour the above-prepared silanized modified CMSs reaction dispersion into the APP suspension, reflux at 90°C for 4 hours, and pour off the supernatant to obtain a crude CMSs-APP product.
[0069] The CMSs-APP crude product was dried at 100°C for 24h, ground, washed several times with absolute ethanol to remove unreacted KH-550 and other impurities, and then dried at 100°C for 24h to prepare the CMSs-APP flame retardant.
