Abstract
The invention provides a PA / ABS alloy material for 3D (Three-dimensional) printing. The PA / ABS alloy material is prepared from the following raw materials in parts by weight: 30 to 50 parts of PA6, 10to 80 parts of ABS (Acrylonitrile-Butadiene-Styrene), 0.1 to 0.3 part of antioxidant, 3 to 5 parts of compatibilizer, 0.1 to 0.5 part of lubricant, 2 to 5 parts of antistatic agent, 10 to 15 parts offlame retardant and 0.5 to 1 part of processing aid. The invention also provides a corresponding preparation method; by using the preparation method, the prepared PA / ABS alloy material has the advantages of high strength, good appearance, high fluidity and capability of being widely applied to the fields of electronic appliances, automobiles and the like; in addition, the material can achieve good antistatic, dustproof and flame retardant effects in the use process and is particularly suitable to serve as a basic material for 3D printing.
Description
technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PA / ABS alloy material for 3D printing and a preparation method thereof. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files, using powdered metal or plastic and other bondable materials to construct objects by layer-by-layer printing. It has been used in jewelry, There are applications in footwear, industrial design, architecture, engineering, automotive, aerospace and more. At present, domestic 3D printing materials still have problems such as insufficient strength and toughness. [0003] Polyamide (Polyamide, referred to as PA), commonly known as nylon, is a general term for polymers containing amide groups in the repeating unit of the main chain of the macromolecule. PA was originally used as a raw material for making fibers, and later became an engineering plastic widely used in ind...
