Abstract

The invention provides a soft-touch low-odor ABS (acrylonitrile-butadiene-styrene) material special for a keyboard and a preparation method thereof, and relates to the technical field of polymer alloymaterials. The soft-touch low-odor ABS (acrylonitrile-butadiene-styrene) material special for the keyboard is prepared from the following raw materials: ABS (acrylonitrile-butadiene-styrene) resin, TPE (thermoplastic elastomer), a compatilizer, a deodorant, a heat stabilizer and a lubricant. The soft-touch low-odor ABS (acrylonitrile-butadiene-styrene) material special for the keyboard has the advantages of being simple and continuous in preparation process, high in production efficiency and stable in product quality; and meanwhile, the soft-touch low-odor ABS (acrylonitrile-butadiene-styrene) material special for the keyboard has good mechanical properties, meanwhile, has low odor and better in soft touch effect compared with general ABS (acrylonitrile butadiene styrene) resin and can beused for the special requirement for the high-end keyboard.

Description

technical field [0001] The invention relates to the technical field of polymer alloy materials, in particular to a special soft-touch low-odor ABS material for keyboards and a preparation method thereof. Background technique [0002] ABS resin material has excellent mechanical properties, good temperature resistance and electrical properties, and good processing performance, and is widely used in various industries. [0003] TPE material is a thermoplastic elastomer material, which has a good material soft touch, and it has excellent properties such as wear resistance, oil resistance, and high temperature resistance. [0004] At present, the keyboard materials mainly use resin materials such as ABS, PBT, and POM. Among these materials, ABS resin materials are not only excellent in mechanical properties, but also relatively cost-effective, and are favored. This kind of cold feeling, as a keyboard material, is not very user-friendly. In addition, the resin material itself has...
