Embodiment 1
[0042] Weigh 150ml of γ-aminopropylmethyldiethoxysilane and 150ml of deionized water, stir and react at 90°C for 4.5h to obtain aminosilane hydrolyzate (HAPMS). 10 parts by weight of HAPMS, 90 parts by weight of octamethylcyclotetrasiloxane (D 4 ), 0.4 parts by weight of hexamethyldisiloxane (MM) and 0.1 parts by weight of potassium hydroxide (KOH) was heated to 140° C., stirred and reacted for 6 hours to obtain polysiloxane. 40 parts by weight of polysiloxane and 10 parts by weight of maleopimaric acid (MPA) were weighed, heated to 91° C. and stirred for 4 hours. After the reaction is completed, weigh 40 parts by weight of the above product and 10 parts by weight of DOPO, dissolve them in 300ml of chloroform, react at 50°C for 12 hours, and remove the solvent by rotary evaporation to obtain maleopimaric acid modified silicon-phosphorus synergistic flame retardant . Weigh 55 parts by weight of polyether polyol (ZS4110, Jiangsu Zhongshan Chemical Co., Ltd.), 45 parts by weigh...
Embodiment 2
[0048] Weigh 150ml of γ-aminopropylmethyldiethoxysilane and 150ml of deionized water, stir and react at 90°C for 4.5h to obtain aminosilane hydrolyzate (HAPMS). 20 parts by weight of HAPMS, 80 parts by weight of octamethylcyclotetrasiloxane (D 4 ), 0.3 parts by weight of hexamethyldisiloxane (MM) and 0.1 parts by weight of potassium hydroxide (KOH) was heated to 140° C., stirred and reacted for 6 hours to obtain polysiloxane. 30 parts by weight of polysiloxane and 20 parts by weight of maleopimaric acid (MPA) were weighed, heated to 91° C. and stirred for 4 hours. After the reaction is completed, weigh 40 parts by weight of the above product and 10 parts by weight of DOPO, dissolve them in 300ml of chloroform, react at 50°C for 12 hours, and remove the solvent by rotary evaporation to obtain maleopimaric acid modified silicon-phosphorus synergistic flame retardant . Weigh 55 parts by weight of polyether alcohol (ZS4110, Jiangsu Zhongshan Chemical Co., Ltd.), 45 parts by weig...
