Abstract

The invention discloses a preparation method of an LED lamp with high heat dissipation and used in the humid and decomposition environment. The preparation method comprises the following steps that waterborne hydroxyl fluorinated polyurethane resin, bamboo carbon fibers, and 2-butoxyethyl acetate are stirred; methyl methacrylate-butadiene-styrene terpolymer is added and continuously stirred to obtain a prefabricated material a; the prefabricated material, waterborne acrylic resin, 2-acetoxy-1-methoxypropane and 2-ethoxyethyl acetate are stirred; talcum powder, montmorillonite, light calcium carbonate, vermiculite powder, and porous powdered quartz are stirred, end vinyl silicone oil, pine tar, a compatilizer, an anti-foaming agent, and a thickening agent are added and uniformly mixed to obtain a pre-processing coating; and the pre-processing coating is applied to the clean surface of an aluminum alloy section bar, an LED rear panel is obtained after solidification, and an LED chip is sealed and packed onto the LED rear panel to obtain the LED lamp with high heat dissipation and used in the humid and decomposition environment.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a method for preparing high heat dissipation LED lamps used in humid and corrupt environments. Background technique [0002] Light-emitting diodes (LEDs) are widely used in the fields of display, TV lighting decoration and lighting because of their advantages that traditional light sources are inferior to, such as environmental protection and energy saving, high efficiency, long life, unbreakable, high switching speed, and high reliability. LED heat sinks are mostly made of aluminum alloy, but the current aluminum alloy is in the market. . . There are still some deficiencies, especially in humid and corrupt environments, where the requirements for moisture resistance and acid-base corrosion are high. At present, it is generally solved by coating heat-conducting coatings on the aluminum alloy surface, but the working reliability of the lamps is still very low. The problem of ...
