Problems solved by technology

[0004] However, due to the presence of amide polar groups in PA6, it has strong water absorption and poor dimensional stability, which limits its application. Because PP (polypropylene) has excellent properties such as easy processing and low water absorption, and the price is only PA6 Generally, the PA6 / PP alloy made by blending PP and PA6 can overcome the inherent defects of PA6 and PP, and has good wear resistance, water resistance, corrosion resistance, molding processability and dimensional stability of products. sex etc.
However, the yellowing resistance is poor, and the antistatic property needs to be improved urgently.

Abstract

The invention discloses a yellowing-resistant antistatic PA6 (polyamide) / PP (Polypropylene) alloy for an automotive interior part and a preparation method. The yellowing-resistant antistatic PA6 / PP alloy for the automotive interior part comprises, by weight part, 100 parts of PA 6, 80 to 120 parts of PP, 0.2 to 4 parts of yellowing-resistant agent and 0.5 to 2 parts of antistatic agent. Preferably, the yellowing-resistant agent is formed by one among the following or the mixture of the flowing which comprises distearyl thiodipropionate, hexamethyl phosphoric triamide, N-(ethoxy carbonyl phenyl)-N'-methyl-N'-phenyl formamidine and titanium dioxide; the antistatic agent is formed by one among the following or the mixture of the flowing which comprises glycerine monostearate, alkyl phosphate diethanolamine salt, N,N-bis(2-hydroxy ethyl)-N-(3'-alkoxy-2'-hydroxy propyl)ammonium methyl sulphate and monopalmitin. The yellowing-resistant antistatic PA6 / PP alloy for the automotive interior part has the advantages of being low in production cost, good in processing performance, good in yellowing-resistant and antistatic performance, environmental friendly and particularly suitable for formation of various automotive interior parts by injection molding.

Description

technical field [0001] The invention belongs to the technical field of chemical materials, and in particular relates to a modified PA6 / PP alloy and a preparation method thereof, in particular to a yellowing-resistant and antistatic PA6 / PP alloy for automotive interior parts and a preparation method thereof. Background technique [0002] The automobile industry has become one of the important pillar industries of my country's national economy.
