Description
Technical field
The invention belongs to chemical material field, it relates to a kind of LED lamp bar silica gel and its preparation method, particularly relate to a kind of fire-retardant LED lamp bar silica gel and its preparation method.
Background technology
Flourish along with LED illumination, LED lamp bar glue becomes the focus that domestic and international researcher is paid close attention to.
At present, lamp bar glue mainly epoxy resin lamp bar glue, urethane lamp bar glue and the organosilicon lamp bar glue that on market, flexible LED lamp bar is conventional, these three kinds of lamp bar glue respectively have its advantage, but also all there is certain defect. Wherein, the most frequently used epoxy resin lamp bar glue cementability is good, but will turn yellow by high temperature, it is easy to becomes crisp cracking, not only affects the see-through of LED, also have impact on aesthetic property; Urethane lamp bar glue also has good cementability, but easily flavescence and hardness are higher, and product only can be applicable to drip glue-type or the soft lamp bar of half-covering tube type, and along with the reduction of temperature, bigger change occurs in the snappiness of lamp bar; Organosilicon lamp bar glue can color inhibition and high/low temperature, to some extent solve epoxy resin and the drawback of polyurethanes lamp bar glue. Therefore, organosilicon lamp bar glue becomes a kind of trend of LED lamp bar glue. But, in epoxy resin, polyurethanes and existing market, existing organosilicon lamp bar glue does not possess flame retardant effect, researching and developing the high performance lamp bar silica gel with flame retardant resistance is the problem that the industry need solve, and has very big challenge, and has very high marketable value.
