Formula of novel glass fiber composite material

Abstract

The invention relates to a formula of a novel glass fiber composite material. The formula comprises the following raw materials in percentage by weight: 5 to 15 percent of glass fiber plain cloth, 1 to 5 percent of phenolic resin, 1 to 10 percent of a barium titanate powder, 5 to 15 percent of a coupling agent, 3 to 9 percent of polypropylene, 2 to 3 percent of epoxy resin, 1 to 5 percent of glassfiber, 11 to 19 percent of an epoxy resin curing agent, 5 to 7 percent of an antioxidant, 3 to 5 percent of a lubricating agent, 3 to 5 percent of calcium alkyl salicylate, 1 to 5 percent of thiophosphate, 5 to 10 percent of kaolin, 1 to 1.5 percent of a traditional Chinese medicine powder, 4 to 5 percent of titanium dioxide and 2 to 4 percent of zinc stearate. The novel glass fiber composite material has good face-modifying, sunproof and skin-care effects.

Description

technical field [0001] The invention is a formula of novel glass fiber composite material. Background technique [0002] The heat dissipation of LED lights is now more and more valued by people. This is because the light decay or life of LED lights is directly related to its junction temperature. If the heat dissipation is not good, the junction temperature will be high and the life will be short. According to the Arrhenius law Every time the temperature drops by 10°C, the life will be extended by 2 times. From the relationship between light decay and junction temperature released by Cree, it can be seen that if the junction temperature can be controlled at 65°C, then the life of light decay to 70% can be as high as 100,000 hours ; but the heat dissipation of the existing actual LED lamps is far from reaching the required temperature, so that the life of the LED lamps has become a major problem affecting its performance. Moreover, the junction temperature not only affects th...

Moreover, the junction temperature not only affects the long-term life, but also directly affects Short-term luminous efficiency
