一种聚缩醛树脂组合物及其制备方法
摘要：
本发明提供一种聚缩醛树脂组合物及其制备方法，该聚缩醛树脂组合物包括：100重量份聚缩醛树脂，0.001～2.0重量份抗氧剂，0.005～3.0重量份甲醛吸收剂，0.002～2.0重量份酸吸收剂，0.001～2.0重量份加工稳定剂，0.1～10重量份改性无机填料，0.005～2.0重量份滑动改进剂与0.1～10重量份韧性改进剂。与现有技术相比，本发明聚缩醛树脂组合物中改性无机填料、滑动改进剂与韧性改进剂协同作用，从而使聚缩醛树脂组合物在保持一定机械强度的基础上，具有较低的摩擦系数和磨损量。
摘要（英）：

The invention provides a polyacetal resin composition and a preparation method thereof. The polyacetal resin composition is prepared from, by weight, 100 parts of polyacetal resin, 0.001-2.0 parts of an antioxidant, 0.005-3.0 parts of a formaldehyde absorbent, 0.002-2.0 parts of an acid absorbent, 0.001-2.0 parts of a processing stabilizer, 0.1-10 parts of modified inorganic filler, 0.005-2.0 parts of a sliding improving agent and 0.1-10 parts of a tenacity improving agent. Compared with the prior art, through the synergistic effect of the modified inorganic filler, the sliding improving agent and the tenacity improving agent in the polyacetal resin composition, the polyacetal resin composition has the lower friction coefficient and abrasion loss on the basis that the certain mechanical strength is kept.
