[0027]

[0028] The preparation method of embodiment 1~3 and comparative example 1~2 is as follows:

[0029] (1) Take polyamide 66, compatibilizer, lubricant, anti-glass fiber exposure agent, toughening agent and processing aid in Table 1 and stir in a speed mixer to fully mix to obtain a blend;

[0030] (2) The blend is metered into a twin-screw extruder, and extruded through melt blending;

[0031] (3) When the head of the twin-screw extruder in step (2) is discharging the material, add the measured glass fiber from the side feeding place of the twin-screw extruder, and then shear, knead, extrude, and dry by the screw , Blended and packaged as finished products.

[0032] Wherein, the aspect ratio of the twin-screw extruder is 40; the temperature of the twin-screw extruder is controlled at 250-270° C., and the screw speed is controlled at 200-220 rpm. ...

Abstract

The invention discloses a reinforced polyamide resin material for aluminum alloy building profiles and a preparation method of the reinforced polyamide resin material. The reinforced polyamide resin material is prepared by mixing polyamide 66, a compatilizer, a lubricant, a glass fiber exposure preventive, a flexibilizer, glass fiber and a processing aid. According to the reinforced polyamide resin material for the aluminum alloy building profiles, the mechanical properties of the material are greatly enhanced while the original properties of polyamide are preserved; meanwhile, the product is good in liquidity and easy to machine and shape and is a preferable choice for thermal insulation strips of the aluminum alloy building profiles.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a reinforced polyamide resin material for aluminum alloy building profiles and a preparation method thereof. Background technique [0002] Polyamide is a material with good mechanical properties, electrical properties and processing properties, which makes it widely used in many fields such as automobile field, machinery industry, electronic and electrical industry, communication, and home appliances. However, due to the high sensitivity of the polyamide material to the notch, its application is limited. Contents of the invention [0003] The object of the present invention is to provide a reinforced polyamide resin material for aluminum alloy building profiles and a preparation method thereof to solve the above technical problems. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A reinforced polyamide resin...
