Manufacturing method for surface sealant of LED flexible strip

Abstract

The invention discloses a manufacturing method for surface sealant of an LED flexible strip, which includes the steps: (1) preparing glue: preparing first glue and second glue required by glue dropping, wherein the first glue comprises cycloaliphatic isocyanate and polyhydric alcohol resin, and the second glue comprises cycloaliphatic isocyanate, polyhydric alcohol resin and phenyl mercuric acetate serving as catalyst; (2) mixing: mixing the first glue and the second glue according to the predetermined proportion, and vacuumizing the mixed glue; (3) dropping the glue: cleaning and baking the LED strip firstly, then fixing the LED strip onto an operating desk, and dropping the mixed glue on the surface of the LED strip; (4) removing bubbles: placing the LED strip dropped with the glue into a vacuum cabinet for removing the bubbles; and (5) baking: placing the glue into a drying oven for baking when the mixed glue on the surface of the LED strip is stirred with a needle and drawing of the glue is in the presence after thirty minutes. The surface sealant of the LED flexible strip manufactured by the method has an ultravioresistant function and is not easy to turn yellow.

Description

technical field [0001] The invention relates to a manufacturing process of a flexible light strip, in particular to a method for making a surface sealant of a flexible light strip. Background technique [0002] At present, the flexible light strips in the market are often processed by epoxy resin dispensing process. The advantages of this method are: low cost, good glue expansion, which is conducive to molding; the disadvantage is: when the amount of mixed glue increases, the curing time will be accelerated. The time is shortened; the hardness of the colloid is low, it is not resistant to UV, it is easy to yellow, degumming and other abnormal problems, and its appearance will be relatively bad after a period of use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for making a surface sealant for a flexible light strip. The surface sealant prepared by the method has anti-ultraviolet performance, good flex...
