具体实施方式
为便于本领域技术人员理解本发明技术方案，现结合说明书具体实施例对本发明技术方案做进一步的说明。
本技术方案一种用于阻燃隔热亚克力板的加工方法，按照以下步骤进行：
第一步，将亚克力板原料加入反应釜中，充分搅拌，在80-85℃的条件下聚合得到液态浆料，然后将阻燃复合制剂加入搅拌溶解，获得混合浆料。
第二步，然后将上述混合浆液注入模具中，在55-60℃的条件下固化4-5小时；在固化期间，使用振动器每隔15-20分钟，振动30-45分钟；完成后，在80-85℃的条件下再固化2-3小时，完成初步固化。
第三步；将上述初步固化后的板材在100-105℃的高温固化设备中高温固化35-40分钟，在常温下冷却，脱模，得到亚克力板半成品。
第四步，向亚克力板半成品的表面多次均匀喷涂阻燃剂，形成阻燃表层，获得阻燃隔热亚克力板。
上述亚克力板原料包括有：90-120重量份的甲基丙烯酸甲酯、5-20重量份的耐热填料、5-10重量份的抗压填料、0.5-2重量份的固化剂、0.3-1重量份的消泡剂、1-5重量份的抗静电剂、1-2重量份的抗菌剂、1-5重量份的增塑剂和2-10重量份的阻燃复合制剂。
上述耐热填料为纳米二氧化硅、氧化锆和硅酸按照1:1:1的混合物。所述抗压填料为乙酸乙酯。所述固化剂为593固化剂。所述消泡剂为二甲基硅油。所述抗静电剂为磷酸钠。所述抗菌剂为氧化铜、硅酸锌和氧化锌按照1:1:1的混合物。所述增塑剂为环氧大豆油。所述阻燃复合制剂为二氧化硅、硅酸钙和纳米蒙脱土按照重量比为1:0.6-0.8:1-1.5混合而成。所述阻燃剂由氯磷酸二乙酯与甲基丙烯酰胺作为原料制得。阻燃剂制备过程为：在烧瓶中放入乙醇，再加入甲基丙烯酰胺，搅拌溶解，30-35℃下缓慢滴加氯磷酸二乙酯，滴加完毕后保温2-3h，然后过滤并用乙醇洗涤，产物于70-80℃真空烘箱中干燥5-7h制得。在第四步中，阻燃剂通过喷枪喷涂在亚克力板半成品的表面。
对上述实施例1至实施例8获得的亚克力板进行性能测试，测试结论为：

2、实施例5至实施例8相比较，实施例5获得的亚克力板在强度、抗冲击强度和阻燃性能三个方面，性能均较为突出，这是因为阻燃复合制剂与足够量的耐热填料具有相互促进作用，使得亚克力板耐热阻燃性能进一步提高。
3、实施例5和实施例6相比较，实施例5获得的亚克力板在强度、抗冲击强度和阻燃性能三个方面，性能均较为突出，特别是在遇到明火时，实施例5亚克力板表面不会出现立即变黑和软化的现象，这说明其表面喷涂的阻燃剂形成的阻燃层具有良好的直接的遇或阻燃的能力。
本发明技术方案在上面结合实施例对发明进行了示例性描述，显然本发明具体实现并不受上述方式的限制，只要采用了本发明的方法构思和技术方案进行的各种非实质性改进，或未经改进将发明的构思和技术方案直接应用于其它场合的，均在本发明的保护范围之内。
