Abstract
The invention discloses a low-smoke halogen-free flame-retardant non-ferrous alloy material for extrusion and stamping and a processing method thereof. The alloy material mainly comprises the following raw materials in parts by weight: 55-60 parts of PC, 15-20 parts of ABS, 10-15 parts of a halogen-free organic phosphorus flame retardant, 0.3-0.8 part of an impact-resistant filler, 0.4-0.9 part of a lubricating agent and 0.1-0.3 part of a toner. The processing method comprises the following steps: drying PC and ABS to be added into a high-speed mixer to be preheated for 5 minutes, adding the halogen-free organic phosphorus flame retardant, the impact-resistant filler, the lubricating agent and the toner into the high-speed mixer, and mixing for 10 minutes at a temperature of 65-70 DEG C. The modified material is not required to be added with a color masterbatch carrier and is good in flame-retardant effect, free of halogen, low in smoke, easy to extrude, stable to form, smooth in punching surface and free of burr phenomena. The processing qualification rate of products is ensured by means of the excellent performance of the material; the low-smoke halogen-free flame-retardant non-ferrous alloy material disclosed by the invention can be widely applied to high-speed rails, nuclear power, new energy and other electrical fields.
Description
technical field [0001] The invention belongs to the technical field of alloy materials and preparation methods thereof, and in particular relates to a low-smoke, halogen-free, flame-retardant non-ferrous alloy material for extrusion and stamping and a processing method. Background technique [0002] At present, most of the PC+ABS alloy materials on the market are of injection molding grade, but there are few modified alloy materials suitable for extrusion, especially low-smoke, halogen-free, flame-retardant non-ferrous alloy materials that are stable in shape and can be used for smooth punching. There are no technologies at all. At present, the electrical standard color RAL-7035 that can be applied to the field of new energy in the existing technology can only be processed by color mixing of masterbatches, which will affect the flame retardancy of the finished product. In view of the above-mentioned defects in the prior art, it is urgent to develop a new type of low-smoke, ...
