Abstract

The invention relates to a heat conducting nylon composite material and a preparation method thereof. The heat conducting nylon composite material comprises nylon and heat conducting fillers, wherein the heat conducting fillers include magnesium hydroxide A and magnesium hydroxide B; the grain size of magnesium hydroxide A is 200-1500 meshes; and the grain size of magnesium hydroxide B is 5000-12000 meshes. The heat conducting nylon composite material and the preparation method have the advantages that as two kinds of magnesium hydroxide with different grain sizes are compounded and adopted as the heat conducting fillers of the heat conducting nylon composite material, large-size magnesium hydroxide grains form a heat conducting network while small-size magnesium hydroxide grains fill the space among large-size magnesium hydroxide, thus finely filling the heat conducting network and being beneficial to improving the heat conductivity of plastics; besides, magnesium hydroxide belongs to a halogen-free flame retardant, so that nylon is endowed with certain flame retardance while the heat conductivity of nylon is improved after magnesium hydroxide is added to nylon.

Description

technical field [0001] The invention belongs to the technical field of heat-conducting materials, and in particular relates to a composite material, in particular to a heat-conducting nylon composite material; the invention also relates to a preparation method of a heat-conducting nylon composite material. Background technique [0002] Nylon is a common engineering plastic, widely used in electrical and electronic, household appliances, electromechanical industry, automotive appliances and other fields. The superiority of nylon thermally conductive plastics is particularly prominent in the field of LED applications. The substitution of thermally conductive plastics for aluminum is a bold leap in the plastics industry, and it is also a trend. [0003] In order to enhance the thermal conductivity of nylon plastics, it is common practice to add thermal conductive fillers to nylon. For example, the Chinese invention patent application "Thermal Conductive Nylon Composite Materia...
