Abstract

The invention discloses a reinforced and toughened weather-resistant and flame-retardant glass fiber reinforced PA66 electric power fitting material and a preparation method thereof. The reinforced and toughened weather-resistant and flame-retardant glass fiber reinforced PA66 electric power fitting material is characterized by being prepared from PA66, glass fiber, melamine cyanurate, zinc borate, aluminum hypophosphite, bamboo charcoal, carbon fiber, silicone rubber, waterborne polyurethane, maleic anhydride grafted polypropylene, a bovine serum albumin solution, potassium titanate whiskers, graphene oxide, a thermotropic liquid crystalline polymer, a halloysite nanotube, a carboxylic multiwalled carbon nanotube, hydroxyl acrylic resin, tripoli, aliphatic polyisocyanate and the like which serve as raw materials. The preparation method comprises the following steps: wrapping the melamine cyanurate with zinc borate to obtain a composite flame retardant; modifying the surface of the glass fiber with bovine serum albumin, and preparing a graphite oxide coated glass fiber composite material according to the electrostatic adsorption principle; spraying a prepared tripoli-containing acrylic polyurethane composite coating on the PA66 to form a coating layer to realize higher corrosion resistance and good mechanical property; and obtaining the reinforced and toughened weather-resistant and flame-retardant glass fiber reinforced PA66 electric power fitting material.

Description

technical field [0001] The invention relates to the field of electric power fitting materials, in particular to a reinforced and toughened weather-resistant and flame-retardant glass fiber reinforced PA66 electric power fitting material and a preparation process thereof. Background technique [0002] Fittings are important components in the power transmission process. For the purpose of energy saving and emission reduction, it is of great practical significance to develop new easy-to-process and recyclable plastic power fitting materials. Glass fiber reinforced PA66 composite material has many advantages such as excellent mechanical properties, small specific gravity, superior electrical insulation performance and easy processing and molding. Easy to degrade. [0003] In the paper "Preparation and Performance Research of New Plastic Power Fitting Materials", Chao Fen made a self-made functional masterbatch to improve the long-term hydrolysis resistance and aging resistance ...
