Abstract

The invention discloses a colorful photoaging-resistant glass fiber reinforced polyamide material. According to the colorful photoaging-resistant glass fiber reinforced polyamide material, following components including polyamide, short glass fiber, a compatible toughening agent, an antioxidant, a lubricating agent, a coupling agent, an ultraviolet light absorber, a thermal-oxidation stabilizing agent and toner cooperate for use, specific weight is reasonably selected, so that chromatic aberration change of the color of a colorful glass fiber reinforced composite material is greatly reduced under the conditions of photoaging and thermal aging, the retention rate of mechanical property is high, and the problems of product performance reduction, product discoloration and the like can be effectively solved. Besides, according to a preparation method of the colorful photoaging-resistant glass fiber reinforced polyamide material, the operation is simple, the cost is low, the production benefit is high, all mechanical properties are high and stable, the method is applicable to industrial production, the service life of the material can be prolonged, the environmental pollution can be reduced, and the prepared colorful photoaging-resistant glass fiber reinforced polyamide material has excellent anti-aging mechanical property and color stability.

Description

technical field [0001] The invention relates to a colored light-resistant aging glass fiber reinforced polyamide and a preparation method thereof, belonging to the technical field of polymer materials and processing modification. Background technique [0002] Polyamide resin (PA) has excellent properties such as wear resistance, firmness, cold resistance, non-toxicity, corrosion resistance, easy molding, and easy dyeing. Its glass fiber reinforced materials are widely used in auto parts, electronic appliances, baby carriages, children's toys and other fields. In recent years, glass fiber reinforced polyamide materials have been more and more widely used in the field of electric tools and garden tools, especially in the electric tool industry. Glass fiber reinforced polyamide materials are used as tool shells, and the color difference of their appearance color is in the normal environment. The change is within 2.0, but under some abnormal use of thermal oxygen photoaging and...
