CN109370144A 一种ABS树脂直接注射成型用高效阻燃抗菌功能母粒及其制备方法 有权

一种ABS树脂直接注射成型用高效阻燃抗菌功能母粒及其制备方法
摘要：
本发明属于塑料改性及加工技术领域，尤其涉及一种可直接应用于ABS树脂制品注射成型加工的高效阻燃抗菌功能母粒及其制备方法；该功能母粒由A和B两种母粒组合而成，A母粒的质量百分比组成如下：载银锌无机抗菌剂6.0～10.0 wt.%、填充剂50.0～70.0 wt.%、热塑性苯乙烯弹性体20.0～38.0wt.%、分散剂0.5～1.0 wt.%、润滑剂0.5～0.1 wt.%；本发明所制备的功能母粒与传统塑料功能母粒相比，避免了载银锌无机抗菌剂与溴系阻燃剂在双螺杆直接强剪切作用下银、锌离子与溴离子之间相互反应导致改性效能互损，显著提高了两者改性效能；该母粒具有易分散易加工特征，可与ABS树脂按配比简单混合后注塑成型，并取得优异的改性效果。
摘要（英）：

The invention belongs to the technical field of plastic modification and processing, and particularly relates to efficient flame-retarding and antimicrobial functional master batch capable of being directly applied to injection molding processing of ABS (Acrylonitrile Butadiene Styrene) resin products and a preparation method of the efficient flame-retarding and antimicrobial functional master batch. The functional master batch is formed by a master batch body A and a master batch body B which are combined, and the master batch body A is prepared from the following components in percentage bymass: 6.0-10.0% of silver-and-zinc-loaded inorganic antimicrobial agent, 50.0-70.0% of filler, 20.0-38.0% of styrenic thermoplastic elastomer, 0.5-1.0% of dispersing agent, and 0.5-0.1% of lubricatingagent. Compared with traditional plastic functional master batch, the prepared functional master batch has the advantages that the situation that under the direct strong shear effect of double screws, silver and zinc ions and bromine ions of the silver-and-zinc-loaded inorganic antimicrobial agent and a brominated flame retardant mutually react, and thus the modification effects are mutually damaged is avoided, and the modification effects of the silver-and-zinc-loaded inorganic antimicrobial agent and the brominated flame retardant are remarkably improved; and the master batch has the advantages of being easy to disperse and process, and can be easily mixed with ABS resin in proportion for injection molding, and the excellent modification effect is achieved.
