Abstract

The invention discloses an anti-flaming PET (Polyethyleneterephthalate) resin composition with a function of preventing yellowing. The anti-flaming PET resin composition disclosed by the invention consists of the following raw materials in parts by weight: 22-85 parts of polyethylene glycol terephthalate, 0-40 parts of chopped glass fibre, 12-20 parts of a fire retardant, 0-15 parts of a flexibilizer, 0.3-0.5 part of a nucleating agent, 0.2-0.5 part of a coupling agent, 0.2-0.5 part of an uvioresistant agent, 0.2-1.0 part of an anti-yellowing agent and 0.3-0.5 part of an antioxygen. A preparation method of the anti-flaming PET resin composition disclosed by the invention comprises the following steps: weighing raw materials according to a weight ratio, mixing and subsequently entering a double-screw extruder, adding chopped glass fiber into six zones in the middle of the extruder, cooling, drying and cutting grains. In the anti-flaming PET resin composition disclosed by the invention, the glass fiber is adopted as the performance enhancements component; the anti-yellowing agent and the uvioresistant agent are added; and the PET resin composition prepared through the synergistic effect of the anti-yellowing agent and the uvioresistant agent has the advantages of excellent mechanical property and anti-yellowing property.

Description

technical field [0001] The invention relates to a flame-retardant PET resin composition with an anti-yellowing function and a preparation method thereof, belonging to the technical field of polymer processing. Background technique [0002] The application range of plastic products is getting wider and wider. Many plastic products are often exposed to light and heat. Under the influence of light and heat, the surface of plastic parts will change color, which will affect the appearance of plastic parts. Polyethylene terephthalate (PET) is the main variety of thermoplastic polyester, and its output ranks first in the chemical fiber field. Due to its excellent comprehensive performance and low cost, it has gradually been widely used in the fields of electronics, electrical appliances, automobiles, and machinery. Especially glass fiber reinforced PET, its products have better mechanical properties and heat resistance. However, due to the ester group contained in the PET structu...
