Abstract

The invention belongs to the technical field of high polymer materials and particularly relates to a PMMA / ASA composite material and a preparation method thereof. The PMMA / ASA composite material comprises the following components in percentage by mass: 49-82 percent of PMMA, 10-25 percent of ASA, 5-20 percent of a toughening agent, 0.2-0.4 percent of an antioxidant, 0.3-0.6 percent of a light stabilizer, 1-2 percent of a scratch resistant agent, 1-2 percent of a toner and 0.5-1 percent of a processing aid. The preparation method comprises the following steps: respectively weighing the raw materials according to the components and the contents thereof and performing mixed treatment to obtain a mixed material; and putting the mixed material into a twin-screw extruder, fusing, extruding and granulating. The composite material is rigid and balanced in overall performance, high in strength, resistant to scratch, ductile, attractive in appearance and very suitable for being used in the fields of automobiles, electronic appliances, other outdoor products and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a PMMA / ASA composite material and a preparation method thereof. Background technique [0002] PMMA (Polymeric Methyl Methacrylate), commonly known as "organic glass" and "acrylic", has excellent light transmission properties, mechanical properties and high coloring properties, excellent aging resistance and weather resistance, chemical properties Stable and resistant to general chemical corrosion such as low-concentration acids and alkalis; PMMA also has the advantages of light weight, low price, and easy molding. Its molding methods include casting, injection molding, machining, thermoforming, etc. In particular, injection molding can be mass-produced, the manufacturing process is simple, and the cost is low. Therefore, its application is becoming more and more extensive, and it can be used in instrumentation parts, automobile lights, optical lenses, tran...
