Problems solved by technology

At present, the general LED lamp does not adopt special heat dissipation measures, and uses the natural heat dissipation of the lamp housing. This method causes the lamp housing to age after the LED lamp has been used for a period of time. Due to the long-term high temperature of the lamp housing, the service life of the LED is reduced; it cannot meet Development Status and Requirements of LED Lamps

Abstract

The invention provides a heat dissipation coating used for LED lights and a preparation method thereof. The coating is characterized by comprising the following raw materials by weight parts: 2-3 parts of methylene bi-cyclohexane amine, 12-15 parts of nano diatomite powder, 15-18 parts of phenolic resin, 1-2 parts of hydroquinone, 4-5 parts of a silane coupling agent KH 550, 1-2 parts of a cross-linking agent TAC, 20-23 parts of organic silicone resin, 8-10 parts of amino silicone resin, 30-34 parts of aluminium nitride, 5-8 parts of ferriferrous oxide, 24-26 parts of ethyl acetate, 10-12 parts of ethyl methyl ketone, 3-5 parts of propylene glycol, 1-2 parts of zinc naphthenate, 1-2 parts of stearic acid, 4-6 parts of butadiene, 1-2 parts of butyl mercaptan tin, and 3-4 parts of a film forming agent. The coating is quick-drying. Meanwhile, through a crosslinking effect of the silane coupling agent KH 550 and the cross-linking agent TAC, a density of the coating is improved, thereby guaranteeing a smooth surface of the coating, increasing beauty, and greatly improving adhesion stress at the same time.

Description

Technical field [0001] The present invention is a coating technology field, which involves a heat dissipation coating. More specifically, it is a cooling coating and preparation method for LED lights. Background technique [0002] With the rapid expansion of LED lights, extending the service life of LED lights has also become an urgent problem.At present, the general LED lights do not use special heat dissipation measures, and the shells of the shell are naturally dissipated naturally. This method makes the LED lights use it for a period of time. Due to the high temperature of the lamp shell for a long time, the LED service life is reduced; it cannot be satisfiedLED light development status and requirements. Invention content [0003] The purpose of the present invention is to provide a heat dissipation coating and preparation method for LED lights. The coatings of the present invention have the advantages of large adhesion, aging resistance, and large heat dissipation factor. ...
