CN104788943A 一种聚酰胺模塑组合物 无效 - 驳回 转让

一种聚酰胺模塑组合物
摘要：
本发明公开了一种聚酰胺模塑组合物，包括以下组成：a、30wt%-95wt%的在苯酚中pH值小于6.9的聚酰胺树脂；b、0-60wt%的增强填料；c、0-60wt%的添加剂和/或其它聚合物；其中，a、b、c三种组分的重量百分数之和为100wt%。本发明选用在苯酚中pH值小于6.9的酸性聚酰胺树脂制备得到的聚酰胺模塑组合物可以有效防止聚合物在注塑过程中发生降解产生气体，进而解决制品流痕、局部发白等技术问题。同时，聚酰胺模塑组合物的颜色得以改善。
摘要（英）：

The invention discloses a polyamide molding composition which comprises the following components: a, 30-95wt% of polyamide resin of which the pH value in phenol is less than 6.9; b, 0-60wt% of a reinforcing filler; c, 0-60wt% of an additive and/or other polymers, wherein the total weight percentage of the three components (a, b and c) is 100wt%. The polyamide molding composition prepared by selecting the polyamide resin of which the pH value in the phenol is less than 6.9 can be used for effectively preventing the polymers from being degraded and generating gas in an injection molding process, and further solving the technical problems of product flow marks, local blanching and the like. Meanwhile, the color of the polyamide molding composition is improved.
