Description

一种导光板的制造方法
技术领域
本发明涉及显示技术领域，特别是一种导光板的制造方法。
背景技术
本发明公开了一种导光板制造方法述导光板的树脂，需要将从导光板的侧方射入的光高效地向面内扩散，故而要求其透明性优良，因此，作为构成导光板的树脂，通常使用未使用过的透明树脂，虽然在制造导光板的过程中产生边角材料，但是在制造要求优良透明性的导光板时无法直接将所述边角材料与未使用过的树脂混合而进行再利用，因此，以往对于在导光板的制造过程中产生的边角材料作为废弃物进行处理，但是，对上述边角材料不进行再利用就处理不仅不经济，另外，从近年来社会要求其目的在于提供对在导光板的制造过程中产生的边角材料等的导光板废料进行再利用而制造高品质的导光板的方法。
发明内容

实现上述目的本发明的技术方案为，一种导光板的制造方法：步骤一、清洗工序，对透明树脂制的导光板的废料进行清洗；步骤二、粉碎工序，将进行了清洗的所述废料粉碎而得到废料粉碎物；步骤三、混合工序，将未使用过的透明树脂和所述废料粉碎物混合而得到混合物；步骤四、成型工序，将所述混合物成形为板状而得到导光板。
所述导光板外表面涂有耐热层。
所述耐热层重量配比为：热塑性苯乙烯20-35％，聚丙烯5-20％、聚乙烯辛烯共弹性5-10％、着色剂0.05-0.15％、复合阻燃剂17-30％、复配抗氧剂0.8-5％、增韧剂1-7％。
所述耐热层涂料是加热熔融得到。
利用本发明的技术方案制作的导光板的制造方法，本发明的导光板制造工艺简单，成本低，可行性好，利用了废料，环保，在重塑的导光板表面涂一层耐热材料，确保使用时间长。
