LED (Light-Emitting Diode) heat radiator and preparation method thereof

Abstract

The invention discloses a preparation method of an LED (Light-Emitting Diode) heat radiator, comprising the following steps of: (a) providing a raw material mixture, wherein the mixture contains epsilon-caprolactam, graphite powder, a catalyst, an auxiliary catalyst, a lubricant and a coupling agent; (b) polymerizing the epsilon-caprolactam in the raw material mixture to form a fused mixture containing polyamide 6; and (c) injecting the fused mixture containing the polyamide 6 into a mould for preparing the LED heat radiator so as to be injected to form the LED heat radiator. According to the preparation method, the LED heat radiator is molded by one step through reaction and injection molding from a monomer, so that a material preparation process is saved, the production efficiency is high and the energy consumption is small; and the heat radiation performance of the prepared heat radiator is excellent.

Description

technical field

[0001] The invention relates to an LED radiator and a preparation method thereof, belonging to the technical field of material preparation, in particular to the preparation of a polyamide 6 resin-based heat-conducting LED radiator by one-step injection molding. Background technique

[0002] As a new type of lighting source, LED light source is known as the darling of green lighting in the 21st century. It has the advantages of small size, low power consumption, long service life, high brightness, low heat, environmental protection, durability, and variety; especially Especially in landscape lighting, its low-voltage power supply has high reliability; good controllability, fast response time, can be turned on and off frequently; good flexibility, and can adapt to decorative lighting requirements of various geometric sizes and different space sizes. However, LEDs generate a lot of heat during lighting, which limits the development of LED lighting technology. ...
