Description
Technical Field
The invention relates to the technical field of modified engineering plastics, in particular to nano TiO 2 In fibre-reinforced thermoplastic resin materials as tonersUse is provided.
Background
Today, the plastic industry is rapidly developing, and thermoplastic resin materials modified by filling with fibrous fillers are widely used due to good mechanical properties and processability. In the practical application process, under a plurality of application scenes, the reinforced modified thermoplastic resin material needs to be subjected to toning treatment, so that the molded product has certain aesthetic degree and batch-to-batch color stability. For example, the housings of high-voltage connectors of new energy vehicles are mostly orange, and the housing colors of small circuit breakers (MCBs) and Molded Case Circuit Breakers (MCCBs) in the application field of low-voltage electrical appliances are mainly light gray, and typically represent products such as the DZ47 series of Zhentai electrical appliances. With the improvement of aesthetic concepts of people, people take white as the U.S., in recent years, low-voltage electrical appliances with the whiteness of more than 88 of the breaker shell are proposed by Schneider, and products with higher whiteness are also successively proposed by Zhengtai electrical appliances and Deleisi.
Currently, in order to endow a molded product of a reinforced modified thermoplastic resin material with light color (such as gray and white) or beautiful color and other appearances, a common technical means is to add a certain amount of white pigment such as zinc sulfide or titanium dioxide (the particle size D50 is about 0.2-1 μm) for color matching in the process of modifying the performance of the thermoplastic resin. The zinc sulfide is added into the thermoplastic resin material because of active chemical properties and is easy to react with substances in the external environment, so that the surface of a molded product is yellowed, and the phenomenon that the large-area appearance is yellowed is poor in the industry, so that the zinc sulfide needs to be carefully considered when being used for preparing light-colored materials. The micro-nano titanium dioxide with the particle size D50 of about 0.2-1 mu m is one of white pigments with the strongest tinting strength, has excellent covering power and tinting fastness, high tinting efficiency and good stability, is widely applied (the dosage is less than 5 wt%) in blending light-colored or beautiful colored thermoplastic resin materials, but has higher hardness, the Mohs hardness of more than 6.0, is easy to generate friction and abrasion with fiber fillers in the blending modification extrusion processing process, and reduces the retention length of the fiber fillers in the thermoplastic resin materials, thereby greatly reducing the mechanical property of the fiber reinforced thermoplastic resin materials, and ensuring that the prepared fiber reinforced thermoplastic resin materials can only be applied to products with lower requirements on the mechanical property, such as MCB shells with low breaking requirements. And when the resin is applied to products with high requirements on mechanical properties of materials, such as MCB shells with high breaking requirements, upper covers of MCCB and the like, the scheme of the fiber reinforced thermoplastic resin material which can only adopt zinc sulfide for color matching at present has higher risk of yellowing of the appearance of the products.
