Embodiment 1

[0018] The back adhesive of the LED light bar of the present invention includes a glue layer and a centrifugal paper, one end of the glue layer is uniformly bonded to the back of the LED light bar, and the other end of the glue layer is bonded with the centrifugal paper, and the glue layer is silicone pressure sensitive glue.

[0019] In this embodiment, preferably, the thickness of the adhesive layer is 0.5mm˜2.0mm. The thickness of the adhesive layer should not only consider the effect of the adhesive layer, but also the overall volume of the light bar. If the thickness of the adhesive layer is less than 0.5mm, the effect of the adhesive layer will be affected. It will increase the thickness of the LED light strip, and at the same time, the thickness of the strip is too thick, which also causes a waste of material objectively.

[0020] In this embodiment, preferably, the solid content of the silicone pressure-sensitive adhesive is 40%-50%. The traditional silicone pressure...

Embodiment 2

[0024] The adhesive coating process of the LED light bar of the present invention comprises the following steps:

[0025] Step 1: Apply silicone pressure-sensitive adhesive on the back of the LED light bar to form a glue layer;

[0026] Step 2: Attach centrifugal paper on the silicone pressure-sensitive adhesive layer;

[0027] Step 3: Cut the whole board after airing, and cut the whole board of the LED light strip into multiple LED light strips.

[0028] In this embodiment, preferably, the coating method in step 1 is spray coating or single stick coating. The coating effect of spray coating or single stick coating is good, the coating amount can be adjusted, the coating is uniform, and the coating precision is high.

[0029] In this embodiment, preferably, the coating thickness of the silicone pressure-sensitive adhesive in Step 1 is 0.5 mm to 2.0 mm. The thickness of the adhesive layer should not only consider the effect of the adhesive layer, but also the overall volume ...

Abstract

The invention relates to LED light bar gum which comprises an adhesive layer and centrifugal paper, wherein one end of the adhesive layer is evenly adhered to the back of an LED light bar, the centrifugal paper is adhered to the other end of the glue layer, the adhesive layer is organic-silicon pressure-sensitive adhesive, and the thickness of the adhesive layer is 0.5mm to 2.0mm. The invention further relates to an LED light bar gum coating technology which comprises the following steps: step one: coating the back of an LED light bar complete board with the organic-silicon pressure-sensitive adhesive to form the adhesive layer; step two: attaching the centrifugal paper to the organic-silicon pressure-sensitive adhesive layer; step three: cutting the complete board after airing, and cutting the LED light bar complete board into a plurality of LED light bars. The gum disclosed by the invention has good adhesiveness and no adhesive residue at high temperature and high moisture, can be adhered to a plurality of materials which are difficult to adhere, and is convenient to use. According to the LED light bar complete board gum coating technology, complete board coating is performed before cutting, and then cutting into bars is performed; thus, production efficiency is greatly improved. Furthermore, cutting is performed after complete board coating, so that the problems that the gum is untidy and the centrifugal paper is broken are avoided.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED light bar back glue and an LED light bar back glue coating process. Background technique [0002] With the rapid development of LED technology, LED products are becoming more and more common in the field of daily lighting, and are currently widely used in decoration. LED light strips are widely used in display and decoration. At present, the LED light strips on the market are all processed and divided into strips and pasted with 3M double-sided tape on the back. The manual operation of the adhesive is not neat, the double-sided tape is easy to break and affects the product quality, and the efficiency of the adhesive is low, which affects the entire production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to design a back glue for LED light bar and a coating process for the back glue of LED light bar, so as to so...
