Abstract

The invention relates to a low-warpage reinforced PBT / ASA (Polybutylene Terephthalate / Acrylonitrile Styrene Acrylate) material, which is prepared from the following raw materials in percentage by weight: 25 to 48 percent of PBT resin, 5 to 10 percent of PET (Polyethylene Terephthalate) resin, 15 to 20 percent of ASA resin, 0 to 3 percent of flexibilizer, 3 to 5 percent of compatilizer, 28 to 35 percent of reinforced fiber and 1 to 2 percent of auxiliary agent. The components of the reinforced PBT / ASA material are all domestic and commercialized, the preparation is convenient, the compatibility of PBT / PET and ASA is good, and the reinforced PBT / ASA material has low warpage, high weather resistance and temperature resistance, and is applied to bases of household appliances and automobile parts.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a low warpage reinforced PBT / ASA material and a preparation method thereof. Background technique [0002] Although PBT resin is an engineering plastic, its price is cheaper than that of general-purpose plastics, with excellent comprehensive mechanical properties, high temperature resistance, and easy flame retardant. Glass fiber reinforced modification, high temperature resistance and good dimensional stability, very widely used. [0003] Reinforced PBT has two disadvantages: 1. The parts are easy to float on the surface, and the appearance is not good. 2. The parts are easy to warp and uneven. [0004] In view of the warping problem, the national invention patent [CN201810799080.X] submitted by Guangdong Shunde Shunyan New Materials Co., Ltd. provides a solution, which adds ASA resin and toughening agent styrene-methyl acrylate-glycidyl methacrylate Copolymer, toug...
