Abstract

The invention discloses a heat-conducting nylon with good flame retardance. The heat-conducting nylon with good flame retardance comprises the following raw materials by weight: 20-40 parts of nylon resin, 10-15 parts of a flame retardant, 2-5 parts of aluminum hydroxide, 14-20 parts of magnesium hydroxide, 5-15 parts of calcium carbonate and 3-8 parts of gypsum. The heat-conducting nylon with good flame retardance has the beneficial effects that: through setting of the specific gravity raw materials, especially the setting of the flame retardant and a flame retardant layer, the flame retardant properties are further enhanced while heat conduction is guaranteed, and the heat-conducting nylon is simple, easy to implement and suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of heat-conducting nylon, in particular to a heat-conducting nylon with good flame retardancy. Background technique [0002] At present, thermally conductive nylon is the most widely used among all thermally conductive materials because of its low price, high thermal conductivity, and superior thermal radiation performance. Especially in the emerging field of LED lighting, high-end products basically use thermally conductive nylon as heat dissipation material. Compared with traditional aluminum, plastic is easy to process, low in cost, and has better heat radiation performance. Most of the current technologies consider the use of high thermal conductivity materials to improve internal heat transfer, but at present it seems that high thermal conductivity materials have poor flame retardancy, so it is necessary to develop a thermally conductive nylon with good flame retardancy.
