Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below.

[0025] The halogen-free flame-retardant and heat-conducting high-temperature nylon compound of the embodiment of the present invention consists of the following components in parts by mass (parts by weight):

[0026]

[0027] In the following examples,

[0028] The PPA resin is preferably polyphthalamide, a medium-low viscosity resin with a melting point above 310°C and a viscosity between 2.4 and 2.7mpa.s, namely Solvay's 6000 series.

[0029] The magnesium hydroxide of Shenzhen Jinhaohui Mining Development Co., Ltd. is selected as the halogen-free flame retardant, and the specification is JLH-QD2. Magnesium hydroxide has a large heat absorption due to its decomposition and produces H2O, which can isolate the air. After its decomposition, the oxide is a high-temperature resistant substance, so it can not only play a role in flame retardancy, but also does not p...

Abstract

The invention discloses a heat-conducting high-temperature nylon composite material and a preparation method thereof. The heat-conducting high-temperature nylon composite material is composed of, by mass, 19-47% of PPA resin, 20-30% of halogen-free flame retardants, 0-5% of liquid fireproofing oil, 30-40% of heat-conducting packing, 1-2% of coupling agents, 1-2% of antioxidants and 1-2% of lubricating agents. The nylon composite material is good in heat-conducting effect and high in flame retardant grade and can meet the non-halogen requirements of flame retardant materials in the European Union standard.

Description

[technical field] [0001] The invention relates to polymer composite materials, in particular to a heat-conducting high-temperature nylon composite material and a preparation method thereof. [Background technique] [0002] As a new generation of green light source and lighting technology with "high efficiency, environmental protection and energy saving", LED lighting has been rapidly developed and widely used in the global lighting industry in recent years. However, the higher the operating temperature of LED lighting, the shorter the service life. Therefore, the design and application of the heat dissipation system of LED lighting lamps play an important role in determining the luminous efficiency and service life of LED lighting lamps. With the continuous development of new LED lamps, designers and manufacturers continue to explore and research, and they all agree that thermally conductive plastics are a reasonable choice for new thermal interface materials. Thermally cond...
