Problems solved by technology

[0003] (1) For PPA and PCT injection-molded LED brackets: Although the molding efficiency of this process is high, the LED brackets are used in light and heat environments for a long time, and the bracket body will turn yellow due to heat, resulting in light decay of the brackets. Reduced overall lifespan of LED lights
Moreover, due to the poor toughness of PPA and PCT materials, it is not conducive to the processing and use of the bracket in the later stage
[0004] (2) For LED brackets formed by EMC curing: Although the brackets formed by EMC have the advantages of low yellowing and low light decay compared with PPA and PCT brackets, the brackets formed by EMC can only be molded and cured, and the curing efficiency is extremely high. Low cost and high cost severely limit the popularization and use of LED brackets made of EMC materials

Abstract

The invention relates to the technical field of LED brackets, in particular to a novel LED bracket and a preparation process thereof. The novel LED bracket is prepared from 15 to 85 percent of polysulfone resin, 0 to 50 percent of a reinforcing modifier and 5 to 10 percent of a raw material component of titanium oxide. The novel LED bracket has the advantages of light failure resistance, high toughness, temperature resistance and high airtightness. The process for preparing the LED bracket comprises steps of melting and granulation of all the components and injection molding. The process is high in injection molding rate and has the advantages of easiness in operation and low cost.

Description

technical field [0001] The invention relates to the technical field of LED brackets, in particular to a novel LED bracket and a preparation process thereof. Background technique [0002] The LED bracket is the bottom base used to fix the LED chips. In the prior art, the preparation process of the LED bracket mainly adopts injection molding of polyphthalamide (referred to as PPA) and poly-1,4-cyclohexanedimethyl terephthalate (referred to as PCT) or adopts epoxy molding compound (EMC for short) curing molding. Yet, still there are following deficiencies in the technology for preparing LED support by above-mentioned: [0003] (1) For PPA and PCT injection-molded LED brackets: Although the molding efficiency of injection-molded LED brackets by this process is high, LED brackets are used in light and heat environments for a long time, and the bracket body will turn yellow due to heat, resulting in light decay of the brackets. The overall service life of the LED lamp is reduce...
