Abstract
本发明公开了一种聚烯烃高透薄膜的紫外阻隔母粒，以重量份计，包含以下原料：聚烯烃载体树脂65～82份、紫外光吸收剂A 6～12份、紫外光吸收剂B 4～8份、无机纳米粒子5～10份、加工助剂3～5份；本发明的紫外阻隔母粒添加到树脂中制备成聚烯烃高透薄膜之后，所得的聚烯烃薄膜制品阻隔率大于98％，透明性大于90％，具有宽幅的紫外线阻隔效果，高透光性，高耐候性，在紫外光照射3000h之后仍可保持良好的紫外阻隔性能；本发明制备的紫外阻隔母粒可直接添加到聚烯烃树脂中进行制品的制造。
Description
技术领域
本发明涉及高分子材料技术领域，具体是涉及一种聚烯烃高透薄膜的紫外阻隔母粒及制备方法。
背景技术
聚烯烃薄膜由于其良好的气密性以及韧性、质轻、透明等特点，被广泛应用于包装行业，尤其是食品包装、日用品以及工业品包装。在塑料包装行业中，高透的塑料薄膜包装能够更好的展现内在商品的完好程度，但同时普通的高透塑料薄膜在使用过程中，容易使得内在商品受到紫外光的辐射而损坏，缩短商品的使用寿命。因此包装用薄膜通常需要添加紫外光吸收剂或者是紫外光屏蔽剂来实现薄膜的紫外阻隔效果，从而对商品进行保护。
紫外光吸收剂能够有效的吸收紫外光，但由于紫外光吸收剂结构的不同，特定的紫外光吸收剂只能吸收特定波长的紫外光，导致紫外光吸收剂的紫外吸收波长范围较短，无法对材料进行良好的紫外保护。三嗪类紫外光吸收剂由于其具有高效性、耐迁移性，常与受阻胺光稳定剂复配用于制品的耐候性能保护，例如，申请公布号为CN106589514B的发明专利申请公开了一种三嗪类紫外光吸收剂与受阻胺光稳定剂复配母粒的制备方法，该母粒在酸性条件下也具有良好的防老化效果。申请号为CN106977811A的发明专利申请公开了一种用于汽车内饰的聚丙烯母粒，将三嗪类紫外光吸收剂与两种受阻胺光稳定剂进行复配，具有低挥发性、高耐迁移性以及良好的耐候性能。但将三嗪类紫外光吸剂与其他紫外光吸收剂复配提高阻隔效果的专利目前还未发现。
紫外光屏蔽剂主要是无机纳米粒子，无机纳米粒子对紫外光的屏蔽作用最主要是通过对光的散射作用以及吸收光子的能量产生电子空穴对二者共同作用。当无机纳米粒子粒径远小于入射光波长时，会发生瑞利散射，瑞利散射对于短波长的光具有更强的散射作用。无机纳米粒子的电子结构是由充满电子的价态和没有电子的导带组成，禁带与导带之间的能带间隙称之为禁带，当入射光能量大于禁带宽度的时候，光子能够被吸收，价态上的电子将会发生跃迁到导带形成自由电子，而能量小于禁带宽度的光子则不能被吸收。无机纳米粒子具有持久的紫外光阻隔效果，能够作用较宽波长范围的紫外光。但在可见光波长范围内，无机纳米粒子也具有一定的散射作用，过多的添加无机纳米粒子会使薄膜的透光率下降，雾度大幅上升。
发明内容
本发明提供了一种聚烯烃高透薄膜的紫外阻隔母粒及制备方法，该紫外阻隔母粒所制备聚烯烃高透薄膜具有稳定的紫外阻隔性能以及对可见光的透明性、并具有持久的力学性能保护效果。
为实现上述目的，本发明采用的技术方案如下：
一种聚烯烃高透薄膜的紫外阻隔母粒，以重量份计，包含以下原料：聚烯烃载体树脂65～82份、紫外光吸收剂A 6～12份、紫外光吸收剂B 4～8份、无机纳米粒子5～10份、加工助剂3～5份。
优选的，聚烯烃载体树脂为聚乙烯树脂、聚丙烯树脂、聚氯乙烯树脂中的任意一种。
优选的，紫外光吸收剂A为三嗪类紫外光吸收剂；紫外光吸收剂B为苯并三唑类紫外光吸收剂、二苯甲酮类紫外光吸收剂、水杨酸酯类紫外光吸收剂中的任意一种。
优选的，紫外光吸收剂A为紫外光吸收剂UV-1164、紫外光吸收剂UV-1577、紫外光吸收剂UV-400、紫外光吸收剂UV-1600中的任意一种。
