High-toughness flame-retardant polyester resin and preparation method thereof
The invention discloses a high-toughness flame-retardant polyester resin. The invention discloses a preparation method of the high-toughness flame-retardant polyester resin. The preparation method comprises the following steps: preparing a flame-retardant prefabricated material; the preparation method comprises the following steps: adding methyl glycol, 1, 2-propylene glycol and 1, 4-butanediol into a reaction kettle under the protection of nitrogen, then adding fumaric acid, heating to 200-210 DEG C, and carrying out condensation polymerization to obtain pre-polymerized resin; cooling the prepolymerized resin, adding phthalic anhydride, dehydrated malic anhydride, hydroquinone and the flame-retardant prefabricated material, heating to 200-210 DEG C, and carrying out condensation polymerization to obtain composite polyester resin; the preparation method comprises the following steps: uniformly mixing granite aggregate and composite polyester resin, adding styrene, calcium carbonate and a curing accelerator, continuously stirring for 1-2 hours, then adding a diluent, a plasticizer, a curing agent and quartz tailings, uniformly mixing, pouring into a mold, and vibrating for 15-60 minutes; curing at 30-50 DEG C for 10-20 hours, demolding, and curing at room temperature for 1-5 hours to obtain the high-toughness flame-retardant polyester resin.
本发明公开了一种高韧性阻燃聚酯树脂。本发明公开了上述高韧性阻燃聚酯树脂的制备方法，包括：制备阻燃预制料；在氮气保护下，将甲基乙二醇、1,2‑丙二醇和1,4‑丁二醇投入反应釜中，然后加入反丁烯二酸，升温至200‑210℃缩聚反应得到预聚树脂；将预聚树脂降温，加入邻苯二甲酸酐、失水苹果酸酐、氢醌、阻燃预制料，升温至200‑210℃缩聚反应得到复合聚酯树脂；将花岗岩骨料、复合聚酯树脂混合均匀，加入苯乙烯、碳酸钙、固化促进剂继续搅拌1‑2h，接着加入稀释剂、增塑剂、固化剂、石英尾砂混合均匀，浇注到模具，振动15‑60min；30‑50℃固化10‑20h，脱模后室温固化1‑5h，得到高韧性阻燃聚酯树脂。
