为验证本发明制备的色母粒是否达到预期的发明效果，对本发明制备的色母粒进行性能试验分析，结果如下所示：
Figure PCTCN2015092609-appb-000001
从上表可以看出，本发明制备色母粒中使混合载体与混合分散剂、热稳定剂产生协同效应，确保材料在加工过程中和在户外长期使用中都能保证稳定性，材料的力学性能更佳，使用色母粒着色达到均匀分散的效果；使用复配分散剂和混合载体产生协同效果，提高了色母粒的分散性、着色力、遮盖力；同时，加入抗菌剂、抗氧化剂和添加剂，可以进一步强化色母粒抗老化性能，提高色母粒的抗菌性能，达到抗菌、抑菌的作用。
最后应说明的是：显然，上述实施例仅仅是为清楚地说明本发明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基 础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引申出的显而易见的变化或变动仍处于本发明的保护范围之中。
