所述的复合填料由下述重量份的原料制得：凹凸棒土15-22、碳酸钙3-6、膨胀珍珠岩4-5、玉石2-3、丙烯酸甲酯1-2、辣椒籽油0.3-0.5；
复合填料的制备方法是：将膨胀珍珠岩、玉石粉碎至颗粒大小为8-16目，将粉碎后的粉料加入适量去离子水里，搅拌均匀，浸泡6-8小时后，再离心处理18-25min，所述离心机的转速为1500-1800r/min，离心之后，过滤、干燥后再在800-950℃下煅烧1-2小时，然后，取出，加适量水搅拌均匀，加10-15%盐酸溶液调PH为4.5-5.5，研磨浆料至400-500目后，再加氢氧化钠溶液调为中性，将所得粉末与其它剩余成分混合均匀后，干燥后，即得。
所述的一种农用氟树脂薄膜，其特征在于：制备方法是：将除复合填料、黄丹外原料混匀，送入双螺杆挤出机的料斗中，再将复合填料、黄丹放入双螺杆挤出机的侧喂料斗，进行熔融、混炼、挤出、冷却、干燥、切粒后，通过吹塑制成厚度60-70um薄膜，即得；双螺杆挤出机的螺杆温度控制在220-230℃之间，螺杆的转速控制在150-160转／分钟。
本发明的有益效果为：本发明薄膜能适用于农用棚室的被覆材料,透光率高，所培育出的作物的颜色等的均匀性较好。
