Embodiment

[0019] The present embodiment is the preparation method of the orange color PA66 of stable color, and it is made by the raw material of following weight part:

[0020] Polyamide PA66 ER27, 60-80 parts;

[0021] Polyamide PA6YH400, 10-20 parts

[0022] Talc powder HTP05L, 5-10 parts;

[0023] Maleic anhydride ethylene copolymer Fusband 493D, 5-10 parts;

[0024] Titanium dioxide RTC-30, 0.2 parts;

[0025] Orange dye Macrolex 3G Orange, 0.6 parts

[0026] Perenone red dye Macrolex EG Red, 0.05 parts.

[0027] The preparation method of the orange PA66 with stable color in this example includes: mixing the above components evenly according to the set ratio, and then extruding them by extrusion process, wherein the extrusion temperature is 240-280°C, and the screw extrusion speed is 300~500rpm.

[0028] In this example, when using the color-stable orange PA66 preparation method to prepare the product, the equipment used includes Coperion STS 50 twin-screw extruder, Brabender...

Abstract

The invention discloses a preparation method of orange PA66 with stable color. The orange PA66 is prepared from the following raw materials in parts by weight: 60-80 parts of polyamide PA66; 10 to 20 parts of polyamide PA6; 5 to 10 parts of talcum powder; 5 to 10 parts of maleic anhydride ethylene copolymer; 0.2 part of titanium dioxide; 0.6 part of orange dye; and 0.05 part of pyrene red dye. According to the invention, the color stability of orange nylon is greatly improved, and the color fixing property is greatly improved.

Description

【Technical field】 [0001] The invention relates to a polymer material, in particular to a method for preparing orange PA66 with stable color. 【Background technique】 [0002] PA66 is also known as polyamide. Because the amide group is a polar group, it can form hydrogen bonds, the intermolecular force is extremely large, and the molecular chains are arranged regularly, so it has excellent mechanical properties, high impact resistance, and high crystallinity. , high melting point, small coefficient of friction resistance, chemical resistance and other advantages, so it is widely used in various fields such as automobiles, electronic appliances, communication equipment, textiles and so on. [0003] However, PA66 has great water absorption, and the humidity of the environment has a great influence on the size and mechanical strength of the product. Therefore, the product stabilization process is a process in which its water absorption reaches equilibrium. Due to the difference in...
