Abstract

The invention discloses a piano black mirror surface luster spray-free glass fiber reinforced PET polyester material and a preparation method thereof, which comprises the following raw materials in parts by weight: 45-85 parts of PET resin, 3-12 parts of PBT resin, and 18-18 parts of glass fiber 45 parts, toughening agent 2-8 parts, heat stabilizer 0.1-0.8 parts, lubricant 0.2-1.5 parts, nucleating agent 0.2-1.5 parts, black masterbatch 0.5-5 parts, surface treatment agent 0.3-5 parts. In addition, the thermal deformation temperature and mechanical properties are stabilized, the injection molding processing cycle is reduced, the black masterbatch improves the blackness, and the piano black highlight appearance of the product is realized, which is crucial to the effect of the present invention. In addition, the preparation method of the invention is simple and controllable, and the production is easy to operate.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to a piano black mirror gloss spray-free glass fiber reinforced PET polyester material and a preparation method thereof. Background technique [0002] In the industry of engineering plastic modified materials, glass fiber is the most commonly used reinforcing material, which can enhance the rigidity and heat resistance of the material, but the use of glass fiber will also cause the gloss of the product to decrease, the surface is rough, and it is not scratch-resistant In order to overcome this problem, the prior art usually uses paint spraying or electroplating to process products, but this has a serious impact on the environment. Under the trend of stricter and stricter national environmental protection requirements, paint spraying and electroplating factories are closed in dominoes. Therefore, Developing spray-free materials has become an urgent p...
