S2、将S1制成的浆料升温至65-80℃，加入改性剂，搅拌；
S3、将S2制成的浆料搅拌30分钟、放料、真空抽滤、烘干滤饼即得的抗黄变珠光颜料；
其中，所述金属氧化物为TiO2或SnO2中的一种或者两种组合；添加量以白色珠光颜料计0.6-1.8%重量份；
所述的改性剂为丁基甲氧基二苯甲酰基甲烷，其添加量为白色珠光颜料计0.2-5%重量份。
所述S1步骤金属氧化物还可以是Al2O3、Fe203一种或者两种；还包括在银白珠光颜料和水的混合浆料中加入Al2O3或Fe203溶液，先将浆料升温75-85℃后，匀速加入Al2O3或Fe203溶液进行包膜，搅拌，期间pH保持在4-7之间。
所述的S2步骤中还包括在浆料升温至80℃时，匀速缓慢加入丁基甲氧基二苯甲酰基甲烷，搅拌。
所述的酸碱液优选盐酸与氢氧化钠溶液。
本发明采用金属有机物包膜法对珠光颜料进行包膜处理使得珠光颜料的表面湿润性得到充分的改善后，通过与改性剂丁基甲氧基二苯甲酰基甲烷的混合融合，降低珠光颜料制品在阳光下暴露产生黄变，从而增加珠光颜料的抗黄变特性；具有质量稳定、易生产、制作成本低、抗黄变效果好等优点。
