Problems solved by technology

[0002] The LED light strip in the LED lamp tube is mostly glued to the inner wall of the lamp tube with silicone glue, and the inner wall of the lamp tube is coated with water-based light-diffusing paint. If the matching between the two is not good, yellowing will easily occur during use. , the traditional test method is to carry out the aging test of the packaged lamp tube. This method is not only time-consuming, but also high in cost. Therefore, there is an urgent need in this field to develop a method for quickly determining the compatibility of the two, so as to select the most suitable coating.

Abstract

The invention discloses a method for quickly determining matchability of silicone adhesive and a water-based photodiffusion coating. The method comprises a step A of coating the inside of a transparent lamp housing with a water-based photodiffusion coating, and after the water-based photodiffusion coating is dried, injecting the silicone adhesive into the transparent lamp housing to form a test coating; a step B of sealing the transparent lamp housing, baking the transparent lamp housing, and observing at intervals of a period of set time whether yellowing occurs in the test coating in the transparent lamp housing; and a step C of recording baking time when yellowing occurs in the test coating. According to the method for quickly determining matchability of the silicone adhesive and the water-based photodiffusion coating, by baking the transparent lamp housing, the yellowing of the test coating is accelerated, and compared with an existing aging test method, the method greatly shortens test cycle and improves determination efficiency.
