本发明涉及一种具有防弹功能的聚氨酯复合镜片的制造方法,采用3～100层镜片交替叠加粘合的方式完成,最外两层使用聚碳酸酯镜片,内部使用聚氨酯镜片或者聚碳酸酯镜片和聚氨酯镜片的交替叠加；镜片之间的粘合采用聚氨酯粘合剂。通过本申请提供的特定粘合剂进行粘合,可以通过重量为16G+0.1G,直径为16mm的钢珠在氮气20KG时发射速度为200米/秒的强力冲击下,镜片不破裂,镜片具有防弹功能的要求。

The invention relates to a manufacturing method of polyurethane composite lenses with a bulletproof function. The manufacturing method is completed in a manner that 3-100 layers of lenses are alternately stacked and bound, polycarbonate lenses are adopted on the two outermost layers, and polyurethane lenses are adopted inside or polycarbonate lenses and polyurethane lenses are alternately stackedinside; and polyurethane binders are adopted for binding between the lenses. The specific binders provided by the method are used for binding, under strong impacting of steel balls with the weight being 16 G+0.1 G and the diameter being 16 mm under nitrogen being 20 KG with the launching speed being 200 m/s, the lenses do not fracture, and the lenses have the requirement of the bulletproof function.
