Abstract

The embodiment of the invention discloses a production method of PUR glue. The method includes: in the production process of PUR glue, adding an adsorbent while adding raw materials to eliminate carbon dioxide gas generated during in the PUR glue production process. According to the embodiment of the invention, the adsorbent can be added into the PUR glue formula according to the generation amount of carbon dioxide gas to eliminate carbon dioxide gas, thus avoiding carbon dioxide gas escape and accumulation on a product surface to form irregular bubbles or pits, and improving the appearance quality of frameless terminal products. Also, the improved scheme adopts easily purchasable and low-cost raw materials, thereby greatly reducing the material cost and manpower cost of frameless terminal mass production.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of terminal frame packaging, and in particular to a method for producing PUR glue. Background technique [0002] At present, the TP modules (TPedge, frame-sealed photovoltaic modules) and the front shell components of the borderless terminal are usually packaged with polyurethane PUR glue, so that the PUR glue will also participate in the composition of the appearance of the structural parts. As users have higher and higher requirements for the appearance of the terminal, higher requirements are also put forward for the appearance of PUR glue in the manufacturing process. However, due to the chemical reactions that occur in the manufacturing process of PUR glue, these chemical reactions will have many adverse effects on the appearance quality; and when the PUR glue is exposed to strong light or under harsh conditions such as acid and alkali corrosion, the PUR glue will also be damaged. ...
